what AI can build
Prompt an LLM for outline, generate slide/cards JSON, render with templates, export PDF/PPTX, and host a share page.
An AI slide generator is buildable, but Gamma's strength is layouts, editing model, exports, hosting, analytics, and shareable deck/site UX.

the prompt
Catalog estimateBuild me an AI slide-deck generator to replace Gamma. Requirements: - A Node CLI around Slidev. `deck new "<topic>"` asks an LLM (key in .env) for an outline, then slide-by-slide content as JSON: title, bullets, speaker notes, layout name. - Render that JSON to a Slidev slides.md; `deck preview` runs the Slidev dev server, `deck export` writes PDF and PPTX. - Five layouts: title, bullets, two-column, big-quote, image-right. Images are optional via an image API key in .env; skip them cleanly when absent. - One theme file for fonts and colors so every deck matches without redesign. - `deck redo <n>` regenerates a single slide by number and leaves the rest untouched. - Decks are files in ./decks/<slug>/ (slides.md plus assets), kept in git and hand-editable after generation. No database. - No accounts, no telemetry; the only network calls are the LLM and optional image API. - Out of scope: a web editor, share links with analytics, collaboration. slides.md in my editor is the editor. - README: keys, export commands, and how to add a layout.

questions
Can AI replace Gamma?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: polished editor, responsive card model. Validate the prompt against your own acceptance criteria before committing.
How much does Gamma cost?
Gamma is listed at about $12/month (Plus, checked 2026-07-30), or $144 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing Gamma?
Honestly: polished editor; responsive card model; exports; analytics; custom domains; template quality; collaboration. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Gamma?
Yes — Slidev (Open-source Markdown/HTML slide deck generator; good foundation for a developer-oriented c). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
