Install SlydeForge
A Windows application, user-mode install, no administrator rights required.
- No more waiting for the AI: while a request is running, "Send" becomes "Add to queue". Your requests go out one at a time, in order, as soon as the AI is free. "Slide 3" still means the slide you were looking at when you typed.
- No more waiting for your review either: results wait for your approval in a non-blocking combined review window, approved in order (D1, D2…), action by action if needed.
- On the thumbnails: D1, D2… badges on modified slides, added slides shown dotted, and an orange "Conflict" badge if you edit by hand a slide that a pending request also changes. Read-only Preview of the presentation with all pending changes.
If Windows shows “Windows protected your PC”
Click “More info”, then “Run anyway”. SlydeForge is an independent project whose installer isn't signed with a commercial certificate yet, so Windows shows this warning as a precaution.
Requirements
- Windows 10 or 11
- No separate Python install required (bundled Python environment)
- No administrator rights required
- Compatible with network-drive installs (UNC)
On first launch
SlydeForge walks you through turning on AI: a free Google key, created in a minute, is enough to try it. Editing, PowerPoint export and slideshows work even without AI.
Quick start
Download and install
Run the installer downloaded above: it installs SlydeForge in your Windows profile, no admin rights needed. Prefer the .zip archive? Extract it fully into a folder of your choice (right-click > Extract All).
Launch
Open SlydeForge from the Start menu or the desktop shortcut. The app bundles its own Python environment: nothing else to install.
Turn on AI
On first launch, SlydeForge walks you through it: create a free Google Gemini key in a minute (or Groq, OpenRouter), no credit card — or use SlydeForge credits. Your own access (Azure OpenAI, Copilot Enterprise, GitHub Models, Ollama) is available with a subscription.
Create your first deck
Describe a brief, attach your source files if needed, and let the AI generate your first presentation.
Version history
Release notes
✨ New — Assistant request queue
- No more waiting for the AI: while a request is running, "Send" becomes "Add to queue". Your requests go out one at a time, in order, as soon as the AI is free. "Slide 3" still means the slide you were looking at when you typed.
- No more waiting for your review either: results wait for your approval in a non-blocking combined review window, approved in order (D1, D2…), action by action if needed.
- On the thumbnails: D1, D2… badges on modified slides, added slides shown dotted, and an orange "Conflict" badge if you edit by hand a slide that a pending request also changes. Read-only Preview of the presentation with all pending changes.
- Validate automatically (option): each result is applied as soon as it is ready, with one undo step per request.
✨ New — Changing a specific area of a slide
- On a busy slide (dashboard, several tables or blocks), a request only changes the targeted area; the rest of the slide stays as it is.
- When in doubt, the assistant asks: the possible areas are numbered in orange on the slide, or you draw it yourself ("I'll draw it on the slide").
✨ New — Live dictation
- The text appears while you speak, like on a phone keyboard, in every prompt box. No Internet needed, in French, English, Spanish, German and Italian (about 40 MB per language, installed once).
- Spoken punctuation ("comma", "period", "new line"…) and automatic capitals. An EN ▾ button switches language in one click.
- "Prepare the microphone" on the first click on "Dictate": checks that the microphone is selected and set up.
✨ Improved — Microphone sound
- A close, clear voice in recordings, where it used to sound "far away": right channel picked, light noise reduction, less room echo, standard loudness for spoken videos.
- Guided microphone setup in 15 seconds (Settings › Voice and dictation… › Microphone), with a clear verdict and before/after listening. Microphone meter in the presenter console while recording.
✨ New — SVG images
- SVG images accepted everywhere (insert, drag and drop, brand kit, brief, assistant), including a drawing pasted from Inkscape or Figma.
- Change the color of an SVG icon: Properties › Image › Drawing color, brand kit or custom color. The assistant can do it too ("make the icons accent-colored").
🧭 Changed — Settings menu
- Organized in 4 sections: Artificial intelligence, Content and media, Application, Updates. New Royalty-free photos…, Voice and dictation… and Language and appearance… windows (with dark mode).
- Clearer AI… window: "Advanced" section, "Assistant" tab, no more cut-off fields.
🐛 Fixes
- "Add a green background to slide 3" gave a red background: the requested color is now respected.
- "Turn slide 3 into a table" no longer produces an empty slide: automatic retry, otherwise the slide stays unchanged with a clear message.
- No more false "figures missing from the sources" alert on 01, 02, 03… numbering.
📖 User guide
- Guide (app and website, French and English) updated: request queue, specific area, live dictation, reorganized Settings, new screenshots.
Release notes
✨ New — Copy / paste
- Copy slides from one project to another, including between two SlydeForge windows: Ctrl+C on the thumbnails, Ctrl+V in the other project. Notes, animations and transitions come along; a single Ctrl+Z undoes the paste. Slides keep the look of their source project, with an "Adapt to project theme" banner one click away.
- With PowerPoint, both ways, plus Office-style paste options (keep source formatting, use project theme, picture). Drag thumbnails between windows to copy.
- Paste content from elsewhere: images (screenshots, browser), formatted text (Word, mail, web, PDF), PowerPoint shapes, Excel or web tables (a real, editable table), a full Word document with its images and tables. Drag an image or text straight onto the slide.
- "Duplicate" (Ctrl+D) no longer overwrites the clipboard.
✨ New — Routines (formerly "Agents")
- "Agents" are now "Routines" (Routines menu,
/routine;/agentstill works). Your existing routines are kept. {{Name}}variables: the information is requested each time you use the routine (text, date, number, list, web address, files), with remembered values and per-client value sets.- ✨ Improve: the AI challenges the routine's prompt. ✨ Translate also translates the variables. A "Client presentation" routine is provided.
✨ New — Brief and sources
- 🔍 Challenge the brief: the AI restates what it understood, proposes an outline and asks at most 4 questions before generating.
- File › Extract project brief: rebuilds a standalone brief that reproduces the same presentation from a project you have edited.
- Blocked web pages (LinkedIn…): assisted reading — open the page inside SlydeForge, frame the useful info and pick up the photo.
- Addresses written "www.…" without
https://are now read along with your request.
✨ New — AI usage
- "AI usage" window (Settings, Subscription menu,
/consommation): all consumption by period, project and AI, with plain-language explanations, a detailed log, CSV export, a personal monthly budget and non-blocking alerts.
🐛 Fixes
- "Rewrite slide 7 as a table and write its notes": the rewrite is no longer lost; the notes describe the new content, follow your tone and duration, and outdated notes are flagged.
Release notes
✨ New — Spell checker
- The spell checker no longer uses AI by default: in the brief, the chat, agents…, it now relies on the Windows spell checker — free, offline, instant, with no tokens used. Nothing changes in use: mistakes underlined in red, one-click correction, "Ignore". It also catches repeated words ("the the") and suggests the word closest to what you typed.
- Advanced AI correction, optional (Settings › AI › "Advanced AI spell checking with this engine", unchecked by default): it also catches grammar, agreement and homophone errors, but uses tokens at every typing pause. The choice is remembered for each AI engine — for example on for a local model, off for an engine that bills its tokens.
🐛 Fixes — Generating from a brief
- Much faster generation start with a local model (Ollama): spell checks on the brief could pile up and run before the presentation outline, causing waits of up to several minutes. Only one check now runs at a time, and it stops as soon as you click "Generate".
- The brief dialog closes immediately when you click "Generate" (it could freeze for about 2 seconds).
- Waiting explained: if the AI model hasn't started answering after 20 seconds, the assistant explains why (local model still loading, or busy with a previous request).
ℹ️ Good to know
- Updating from within SlydeForge: nothing to do, as usual.
Release notes
🐛 Fixes
- Component installation: frozen progress bar and "SlydeForge is not responding": after updating from an older version, leftover launcher settings slowed the component installation down considerably and froze the startup window on "Preparing download…". This is fixed: a full installation takes about 40 seconds again.
- More informative progress bar: it now moves steadily through every step — looking for components, downloading file by file (name and size shown), then installing, the longest step.
ℹ️ Good to know
- Updating from within SlydeForge: nothing to do, as usual.
Release notes
🎨 AI Theme Studio — the highlight of this release
- Create a theme with AI (Theme menu, ✨ Create with AI… button in the theme editor, ✨ New theme… button in the brief): only a short text is required (business, mood). Optional: website, colors (enforced or as inspiration), logo, images, icons, existing documents (PPTX, PDF, screenshots), expected layouts, fonts and format.
- 3 clearly different proposals in a single AI call, shown as real slides with content drawn from your business. Click to choose, double-click to see every layout, Ctrl+click to blend two proposals (0 tokens) or ✨ Refine with a free-form request.
- Cost shown before you start, then the amount actually used.
- Your website read in under 20 s: colors actually displayed, fonts, logo, photos, business. A site that blocks automated reading is reported, never bypassed.
- Step-by-step progress, with a Stop button.
- Consistent quality whatever the AI model: palettes with computed contrast, 8 graphic styles (banner, rules, diagonal, soft shapes, frame, dot pattern, offset blocks, full-page photo), checked layouts (overflow, broken words, logo legibility).
- Fonts: a missing font is replaced by a close one, and you're told; a Google Font installs in one click, without admin rights.
- Logos legible everywhere: several variants per theme (color, white, monochrome…), each slide automatically picks the most legible one for its background, on screen and in PowerPoint.
- The created theme applies its style to all generated slides.
✨ New
- AVIF images accepted everywhere (theme, image insertion, brief, chat, workflows).
- Thumbnails and drag-and-drop for files in the Studio, and a large view of each proposed layout.
🚀 Startup and installation
- New, lighter
SlydeForge.exelauncher: SlydeForge starts directly, with no command window or hidden step. In Task Manager, the app now shows up as "SlydeForge". - Fewer antivirus alerts: the new startup avoids a sequence that some antivirus products (including Kaspersky) wrongly took for malware. The launcher now carries its publisher and version information.
- Faster startup: components checked in ~0.3 s instead of about 4 s, roughly halving the time between the click and the loading screen.
- SlydeForge-branded startup window when components need installing (first launch), with a real progress bar and a clear message if something goes wrong.
- First launch explained: if Windows shows "Windows protected your PC", SlydeForge explains once why, and how to stop seeing it. A "LISEZ-MOI - Premier lancement.txt" file (French and English) is included in the .zip archive.
🐛 Fixes
- Updates: no more command window or full reinstall of components (~310 MB) after each update; an interrupted update is offered again on next launch.
- Much faster first installation: 34 s instead of almost 3 minutes.
- "Failed to load Python DLL" error when changing language.
- A second SlydeForge window wouldn't open if one was already open.
- Small windows flickering at startup; invisible close button on the loading screen.
- Some AI providers (Copilot GHE) were wrongly treated as unable to see images.
- Studio: a reference page (Wikipedia, LinkedIn…) no longer gives its own logo to the theme; an error after the AI response no longer loses the paid call ("Rebuild (0 tokens)").
- Team layout: member roles now meet the minimum readability contrast.
ℹ️ Good to know
- Updating from within SlydeForge: nothing to do, as usual.
- Installing from the .zip archive: before extracting it, right-click the .zip file › Properties › tick Unblock › OK. Windows then won't show a warning at launch.
Release notes
🎬 Motion engine — the highlight of this release
- The slideshow really plays animations: fade, rise, pop, bounce, wipe, mask reveal, exits, pulse… Text stays sharp, a click during an animation moves to the next step, and going back or jumping to a slide shows it without replaying anything.
- Morph transition: between two slides, shared elements glide, resize, change color and rotate instead of disappearing. Exported as a real PowerPoint Morph (with a fade fallback for PowerPoint 2016, LibreOffice and Google Slides). Duplicate for Morph from a right-click.
- Kinetic typography and living data: text revealed line by line, word by word or letter by letter, a counter on a figure ("12,500 customers", "98.6%"…), highlight, charts and timelines that draw themselves, a slow Ken Burns zoom on the background image.
- 10 motion styles (Corporate sober, Keynote, Tech neon, Editorial luxury, Cinema, Data storytelling…) in 3 clearly distinct intensities (Subtle, Elegant, Spectacular), and 4 animated backgrounds in your brand-kit colors.
- Motion window (Ctrl+Shift+M): looping animated preview of the slide, a plain summary of what the style does, applied to the whole deck, the current slide or the selected slides. ▶ Play button in the editor to replay a slide without starting the slideshow.
- "Animate slide (AI)" knows all these effects, with a before/after preview and lines you can uncheck; the chat understands "put a counter on the figure" or "do a Morph with the previous slide".
- Faithful PowerPoint export: native effects, "with / after previous" triggers finally respected, fully editable file. "100% PowerPoint" mode so the slideshow and the file play exactly the same thing.
- Check motion: non-blocking warnings (animation too long, slide empty until the click, too many strong effects…).
✨ New
- Group / ungroup objects (Ctrl+G / Ctrl+Shift+G): move and resize together, kept as real groups in PowerPoint.
- Edit several objects at once from the properties panel (text, colors, outline, shadow, animation, position…), without touching anything else on each object.
- Better-looking tables: style gallery in your brand-kit colors (Grid, Clean, Banded, Accent, Minimal), solid or underlined header, total row, density, vertical alignment, readability fixed automatically.
- Slide language in the brief: language selector (5 languages) saved in the project, then respected by AI edits and speaker notes.
- GitHub Copilot Enterprise: list of the models your organization actually allows, a clear message when a model is refused, and "Test connection" tests the configured model.
- Simpler thumbnail context menu: 8 entries grouped by purpose instead of 17, with no feature removed.
🔒 Subscription
- From the Essential tier: personal AI connectors (OpenAI-compatible API, GitHub Models, Copilot Enterprise), motion styles and animated backgrounds. Classic animations and transitions, Morph and "Simple animations" stay free; an already staged deck plays and exports normally.
- Free trials (Gemini, Groq, OpenRouter) capped at 300,000 tokens per month without a subscription, uncapped with one.
🎯 Better results with local models (Ollama, gemma4…)
- No brand-kit slide delivered empty anymore: a poorly filled slide is retried on its own, otherwise its content goes into an equivalent layout.
- Response format enforced for local models: tables, steps and comparisons finally filled with the real data.
- The model's context window is detected and respected; "Test connection" explains how to enlarge it, based on your actual setup.
- Thinking mode no longer makes generation fail: a step that runs out of room is redone without thinking.
🐛 Fixes
- Reliable token count: the amount shown is exactly the amount counted, reasoning and images included; the cost of a cancelled action stays visible.
- PPTX export: no more white table rows with unreadable text.
- Lists shown in brackets (
["…", "…"]) on some slides. - "Custom…" color in the properties panel never applied.
- Dark theme: disabled items are now greyed out.
Release notes
🎯 New generation engine — the highlight of this release
- The AI writes, SlydeForge lays out: the AI now only writes the content; the layout is computed from your brand kit (grid, typography, measured contrast, no overflowing text). Measured on an 8-slide presentation: 13.6 s instead of 152.7 s, about 17 times fewer tokens, no layout defect detected (24 before).
- Your brand kit's slide templates guide the result in every format (16:9, square, portrait) and are preferred by the plan.
- Visible progress: the plan's titles, then each slide, appear as they arrive, at no extra cost.
- A complete result from the very first generation (checkboxes in "New from a brief"): transitions and animations (free, no AI call) and speaker notes.
- Your brief is really used: attached images are placed on slides (portraits on a "team" slide), web links cited are actually read as sources, and royalty-free photos are kept far more often.
✨ New
- Two-step Formatting: other structures, then bold art directions (value-based color coding, title band, depth, status icons…) as real previews. ✨ Refine bar for a free request or to combine two proposals, 🔍 Enlarge to compare full size, Create a new slide checkbox to keep the original.
- Challenge asks questions first: a diagnosis, then up to 3 one-click questions before rewriting the slide; about 70% fewer tokens, and figures or dates lost or added are flagged.
- Photo button (
/suggest_image): up to 6 royalty-free photos already built into the slide, with a readable credit. - AI-generated images: AI image button (
/generate_image) and a "Generate AI images" checkbox in "New from a brief", with an upfront cost warning (requires a configured image generation service). - Search the whole presentation (Ctrl+F): slides, tables, charts, timelines and notes, with highlighting, a counter and a list of matches.
- Local model check (Ollama…): "Test connection" explains in plain words whether the model is suitable (speed, thinking, vision) and how to pick another one.
- Zoom in the before/after preview: click an image to compare full size.
🐛 Fixes
- Generation stuck for minutes with a local "reasoning" model (gemma4, qwen3…): thinking is now turned off automatically (8-slide presentation in 19.8 s instead of 53.9 s).
- Spell check: the chosen correction replaces exactly the misspelled word, and clicking in the text works normally again.
- "Team" slide left empty despite attached photos; extra empty circle in a brand-kit agenda.
- Only one art direction offered on a slide based on a brand-kit template.
- A Challenge rewrite can no longer make the slide poorer (lost photo, icons or cards) without warning you.
- Numbers better centered in badges; table and chart text more faithful on screen; bullets properly spaced in the PowerPoint export.
Release notes
✨ New
- Tables: per-axis borders and custom sizing — row and column separators can now be shown independently (horizontal only, vertical only, both, or neither), and multiple selected columns or rows can be resized at once to a precise width or height.
- Hyperlinks now exported to PowerPoint: text carrying a link stays clickable during the presentation, not just in the SlydeForge preview.
🐛 Fixes
- Multi-series charts turning monochrome, or unreadable text on a dark background: each series gets its own distinct color again (preview and PowerPoint export), and pie chart label text now automatically switches between white and black based on the background color.
- Double-clicking an element (timeline, table, chart…) sometimes ALSO opened the slide background properties — fixed.
- The custom color picker would sometimes reopen itself right after confirming a choice — fixed.
- Buying a paid marketplace component: now redirects straight to the slydeforge.com pricing page, without asking for an email address inside the app.
