Open Notebook
open sourceMITSelf-host36kaug 2026A private source notebook with search and chat; capture is upload-first, not frictionless.
The catch vs Saner.AIIt is an upload-first source notebook, so quick capture, automatic connections, and everyday personal-knowledge workflows are weaker than Saner.AI's.
Install, platforms & data +
- platforms
- webself-hosteddocker to self-host
- install
- Download the official Docker Compose file, set an encryption key, and start the Open Notebook and SurrealDB containers
- setup
- Docker and 4 GB RAM are required, and the user must replace default secrets then configure at least one model provider or add an Ollama container
- engines
- OpenAI, Anthropic, Google Gemini/Vertex, OpenRouter, Groq, Mistral, DeepSeek, xAI, Azure/OpenAI-compatible services and local Ollama; optional speech providers for podcast generation
- your data
- Notebook metadata, notes, source records and encrypted provider credentials live in the self-hosted SurrealDB; uploaded source files live in the mounted notebook_data directory, with selected context sent to any cloud AI provider used

Khoj
open sourceAGPL-3.0Local or hosted36kaug 2026Search and chat across personal files, now self-host only because the cloud shut down.
The catch vs Saner.AIIt is strongest at searching and chatting over existing files, not Saner.AI's frictionless capture and automatic visual connection of new knowledge.
Install, platforms & data +
- platforms
- desktopwebself-hosteddocker to self-host
- install
- Use the hosted app, or self-host the server with Docker or pip and optionally install its desktop/browser/Obsidian clients
- setup
- The hosted app is immediate, but private self-hosting requires Docker or Python, PostgreSQL/pgvector, model configuration and an initial document index
- engines
- Local OpenAI-compatible servers such as Ollama, llama.cpp, LM Studio or vLLM, plus OpenAI, Anthropic Claude, Google Gemini and other cloud APIs
- your data
- Hosted accounts store chats and indexed documents in Khoj's cloud; self-hosting stores application data and vector embeddings in the operator's PostgreSQL/pgvector database while original synced files remain at their source

Atomic
open sourceMITLocal or hosted1.6kjul 2026Capture, automatic connections and cited chat over your notes; bring the model yourself.
The catch vs Saner.AIIt covers capture, links, and cited chat, but its mobile capture, integrations, and overall polish are less mature than Saner.AI's managed workspace.
Install, platforms & data +
- platforms
- desktopmobilewebself-hostedextensionone-click install
- install
- Download the macOS/Windows/Linux desktop release, use Atomic Cloud, or self-host its three-service Docker Compose stack
- setup
- The desktop binary installs cleanly, but first-run setup cannot finish without an embedding and generation backend, either an API key or Ollama plus downloaded models
- engines
- Ollama, OpenRouter or any OpenAI-compatible model/embedding endpoint, with separate choices for embeddings, tagging, wiki generation and chat
- your data
- Knowledge is stored as Markdown 'atoms' plus tags, chunks and sqlite-vec embeddings in Atomic's local/server data directory; cloud users keep that database on Atomic's hosted service, and cloud-model calls send relevant text to the provider
