The first release of Lectern: AI agents that turn a prompt, spreadsheets and documents into an editable presentation.

What's in it

The full flow: brief, Strategist interview, outline you approve, live build with pause and resume, chat edits, export.
Agents: Strategist, Analyst (numbers traced to real cells), Writer, Art Director, Renderer, a deterministic Critic, Editor and Exporter. Your standing rules go into every prompt.
Critic: lints every slide for overflow, small text, weak headlines, contrast, mismatched numbers and placeholder text. Fix in one click, or keep and turn it into a rule.
Undo: per-slide undo, and undo of one chat request that keeps your later edits.
Data: charts and stats linked to sheet ranges; refreshing updates headlines and notes too.
Brand kits: import a .potx for colours, fonts, logos and layouts.
Export: PPTX with native charts, tables and text; vector PDF; PNG slides; speaker notes; an editability report.
Share and present: read-only share links and a presenter view with notes and a pace timer.
Models: Claude Code (local login), Anthropic, OpenRouter, LiteLLM and other OpenAI-compatible gateways, and an offline mode that needs no key.
Images and video: Higgsfield, Google Imagen and Veo, OpenAI Images, FLUX, Runway, Pexels and uploads.
MCP server: 16 tools over stdio (uv run lectern-mcp) or HTTP (/mcp) for Claude Code, Codex, Cursor, Gemini CLI and Antigravity. Approving an outline always stays with a person.

cd server && uv sync && uv run uvicorn lectern.main:app --port 8000
cd web && pnpm install && pnpm dev

Invite by email, comments, Google Slides export and accounts are designed but not built.
Removed slides can't be restored by undo.
PPTX files don't embed Urbanist, so PowerPoint shows a fallback font on machines without it. The PDF is exact.
Paid image providers are wired in but need your own keys or credits.
