| Notestack turns any blog, newsletter, website or folder of markdown into a grounded research notebook, then into audio | |
| overviews, videos and launch kits, all traced back to the exact lines the writer actually wrote. | |
| - Design doc: [docs/DESIGN.md](docs/DESIGN.md) | |
| - Foundations task list: [docs/PHASE0.md](docs/PHASE0.md) | |
| ## Why Notestack instead of NotebookLM | |
| NotebookLM is a great general research notebook. Notestack is built for people who publish: it starts from your whole | |
| archive, stays in sync with it, cites the exact lines behind every answer, and turns what you wrote into things you can ship. | |
| | | Notestack | NotebookLM | | |
| | --- | --- | --- | | |
| | Getting your writing in | Syncs any blog, newsletter or site (Substack, Ghost, WordPress, Medium, RSS, or crawled with Firecrawl), plus md, txt, html and pdf uploads | Add sources one at a time | | |
| | Stays in sync | New posts arrive automatically | Re-add sources by hand | | |
| | Citations | Exact line ranges, verified before you see them | Passage level citations | | |
| | Not in your sources | Says so; unverifiable claims are dropped | Grounded, passage citations | | |
| | Audio | Two hosts on ElevenLabs voices, or your consented voice clone | Two host overviews, Google voices | | |
| | Video | 9:16 shorts, 16:9 explainers, 1:1 audiograms, quote cards, in your brand | Video overviews | | |
| | Publishing | Launch Kits (threads, LinkedIn, Notes, Bluesky, SEO, carousels) and auto posting | Not a publishing tool | | |
| | Your voice | Voice profile learned from your posts, used in every draft | General purpose writing | | |
| | Seeing your archive | Topic constellation with rising and dormant topics, evergreen resurfacing | Idea Constellations per notebook | | |
| The full comparison lives at [notestack.ai/notebooklm-alternative](https://notestack.ai/notebooklm-alternative). | |
| ## Layout | |
| ``` | |
| backend/ FastAPI + SQLAlchemy + Alembic, Postgres job queue worker, DSPy (LLM agnostic, Z.ai first) | |
| frontend/ React + Vite + TS: night sky landing, pricing, blog, auth, Mission Control | |
| renderer/ Remotion compositions + render service that uploads to R2 via presigned PUT; trailer and demo scripts | |
| marketing/ Launch trailer, poster and logo files | |
| docs/ Design doc and task lists | |
| ``` | |
| ## Run locally | |
| ```bash | |
| cp .env.example .env # fill LLM_API_KEY (Z.ai), GOOGLE_CLIENT_ID, RESEND_API_KEY | |
| docker compose up --build | |
| ``` | |
| - App: http://localhost:5173, API: http://localhost:8000/docs, MinIO console: http://localhost:9001 | |
| - Local storage is MinIO standing in for R2. Presigned URLs point at `http://minio:9000`, so add | |
| `127.0.0.1 minio` to your hosts file for browser uploads to work locally. | |
| - With `EMAIL_PROVIDER=console`, verification codes print in the `api` logs. | |
| Without Docker (one API process does everything): | |
| ```bash | |
| cd backend && python -m venv .venv && .venv/Scripts/pip install -r requirements.txt | |
| alembic upgrade head && uvicorn app.main:app --reload # SQLite at backend/notestack.db | |
| cd frontend && npm install && npm run dev | |
| cd renderer && npm install && npm start # only needed for videos, quote cards, carousels | |
| ``` | |
| - With `ENV=development` the API runs the job worker in process (`RUN_WORKER_IN_API`), so syncing, | |
| topic mapping, audio and launch kits work without a second terminal. In production run | |
| `python -m app.worker` separately and set `RUN_WORKER_IN_API=false`. | |
| - With no R2 settings, files live on local disk under `backend/.storage` and are served through | |
| signed `/api/storage/local/...` URLs (range requests supported for audio and video seeking). | |
| - Audio needs `ELEVENLABS_API_KEY`; everything text based needs `LLM_API_KEY`. | |
| - Launchpad: Bluesky connects with an app password. X and LinkedIn need developer apps; the | |
| redirect URIs are listed in `.env.example` and on the Launchpad page. Substack Notes has no API, | |
| so those posts (and any post without a connected account) arrive as an email reminder at send time. | |
| ## What is in the app | |
| | Menu | Does | | |
| | --- | --- | | |
| | Mission Control | Pre-flight checklist, jobs in flight, sources, notebooks, recent launches, upcoming posts | | |
| | Notebooks | Group posts, chat with cited answers (history kept), summaries, audio overviews, videos, quote cards | | |
| | Sources | Connect feeds (Substack archive included), import one URL, upload md/txt/html/pdf, read posts by line | | |
| | Topic map | LLM tagged topics per post, merged into a constellation; make a notebook from any topic | | |
| | Voice profile | Writing voice built from your posts (editable), host voices, consented voice cloning | | |
| | Video and audio | Audio overviews, 9:16 shorts, 16:9 explainers, 1:1 audiograms, quote cards | | |
| | Launch Kit | Hooks, X thread, LinkedIn, Substack Notes, Bluesky, SEO pack, carousel, quote cards, all editable | | |
| | Launchpad | Calendar and agenda, auto posting to X, LinkedIn and Bluesky, email reminders, tracked links, engagement | | |
| | Archive | Every generated artifact with filters, players, downloads, retry and delete | | |
| | Resurfacing | Evergreen scores and reshare angles for old posts, on this day, straight into a kit or the calendar | | |
| | Settings | Profile, workspace, brand kit, privacy, plan usage meters, connections, sign out everywhere, delete | | |
| ## Key choices | |
| | Concern | Where | | |
| | --- | --- | | |
| | Cloudflare R2 storage (keys, presign, uploads) | `backend/app/services/storage.py`, `backend/app/routers/storage.py` | | |
| | Resend email + unsubscribe + campaigns | `backend/app/services/email.py`, `backend/app/worker.py` | | |
| | Google + email code auth, JWT revocation | `backend/app/auth.py`, `backend/app/routers/auth.py` | | |
| | Research over posts as files (no embeddings) | `backend/app/corpus.py`, `backend/app/pipeline/research.py` | | |
| | LLM provider (swap by env) | `backend/app/llm/provider.py`, `.env` `LLM_*` | | |
| | Three plans, billing off | `backend/app/services/plans.py`, `BILLING_ENABLED` | | |
| | Blog posts | `frontend/src/content/blogPosts.ts` (`/blogs`, `/blogs/:slug`) | | |
| | Logo | `frontend/public/logo.svg` (white tile, black ringed planet); lockups in `marketing/logo/` | | |
| | Sky background | `frontend/src/components/SkyCanvas.tsx` | | |
| ## Switching LLM providers | |
| ```bash | |
| # Z.ai (default). Cheaper: glm-5.3-flash. Free for dev: glm-4.7-flash | |
| LLM_MODEL=openai/glm-5.3 LLM_API_BASE=https://api.z.ai/api/paas/v4 LLM_REASONING_EFFORT=low | |
| # Anthropic | |
| LLM_MODEL=anthropic/claude-sonnet-5 LLM_API_BASE= | |
| # OpenAI | |
| LLM_MODEL=openai/gpt-5 LLM_API_BASE= | |
| ``` | |
| ## Videos and brand | |
| | Asset | File | Rebuild | | |
| | --- | --- | --- | | |
| | Launch trailer (82 s, "Coming soon") | `marketing/notestack-launch.mp4` | `renderer/scripts/make_launch_vo.py`, then `make_launch_music.py`, then `npx remotion render src/index.ts LaunchTrailer ../marketing/notestack-launch.mp4` | | |
| | Landing demo (47 s) | `frontend/public/demo.mp4` | `renderer/scripts/make_demo_vo.py`, then `npx remotion render src/index.ts LandingDemo ../frontend/public/demo.mp4`, then bump `DEMO_VERSION` in `Landing.tsx` | | |
| | Logo | `marketing/logo/` (mark, lockup for dark and light backgrounds) | Mark is `frontend/public/logo.svg`; the renderer uses a copy at `renderer/public/logo.svg` | | |
| Narration is voiced on ElevenLabs (run the scripts from `backend/` with `PYTHONPATH=.`); music is synthesized, no samples. | |
| Preview any composition with `cd renderer && npm run studio`. | |
| ## For AI agents | |
| `https://notestack.ai/llms.txt` tells assistants and crawlers what Notestack is, which pages answer which questions, and | |
| what not to index. It is generated on every build from `frontend/seo/sitemap.ts` alongside `sitemap.xml` and `robots.txt`, | |
| so new blog posts appear in all three automatically. | |
| ## Roadmap | |
| - [ ] Complete the checkout flow | |
| - [ ] Delete a free tier knowledge base after one week, prompting the writer to upgrade to keep it | |
| - [ ] Onboarding message: the free tier indexes the first 5 posts; upgrade to index the rest | |
| - [ ] An inner "galaxy" view inside the topic map, using a statistical word model to link related pieces of knowledge | |
| - [ ] Make the main app view look good on mobile | |
| - [ ] Explore a whole website through its `llms.txt` and sitemap XML, so every post and page gets included | |
| ## Rules | |
| - No em dashes in any UI, email or generated copy. `npm run check:copy` and | |
| `app/llm/postprocess.py` enforce it. | |
| - Palette is black, `#217cff` and white only. | |
