Saner.AI alternatives: 8 open-source picks
These 8 Saner.AI alternatives replace it for $0, led by Open Notebook, Khoj and Atomic. All 8 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
A private source notebook with search and chat; capture is upload-first, not frictionless.
licenseMIT
runsyour server
installDownload the official Docker Compose file, set an encryption key, and start the Open Notebook and SurrealDB containers
enginesOpenAI, Anthropic, Google Gemini/Vertex, OpenRouter, Groq, Mistral, DeepSeek, xAI, Azure/OpenAI-compatible services and local Ollama; optional speech providers for podcast generation
dataNotebook 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
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.
setupDocker 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

Search and chat across personal files, now self-host only because the cloud shut down.
licenseAGPL-3.0
runsyour machine or their cloud
installUse the hosted app, or self-host the server with Docker or pip and optionally install its desktop/browser/Obsidian clients
enginesLocal OpenAI-compatible servers such as Ollama, llama.cpp, LM Studio or vLLM, plus OpenAI, Anthropic Claude, Google Gemini and other cloud APIs
dataHosted 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
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.
setupThe hosted app is immediate, but private self-hosting requires Docker or Python, PostgreSQL/pgvector, model configuration and an initial document index

Capture, automatic connections and cited chat over your notes; bring the model yourself.
licenseMIT
runsyour machine or their cloud
installDownload the macOS/Windows/Linux desktop release, use Atomic Cloud, or self-host its three-service Docker Compose stack
enginesOllama, OpenRouter or any OpenAI-compatible model/embedding endpoint, with separate choices for embeddings, tagging, wiki generation and chat
dataKnowledge 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
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.
setupThe 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
