licenseMIT
runsyour server
installDeploy the documented Docker Compose stack; source and manual installation paths are also available
enginesMore than a dozen configurable providers including OpenAI, Anthropic, Gemini/Vertex, OpenRouter, Ollama, and LM Studio, assigned separately to chat, embeddings, text-to-speech, and speech-to-text roles
dataUploaded sources, generated audio, and checkpoints live in the mounted ./data directory, while notebook records and indexes live in the mounted SurrealDB data directory
the catch vs LateralIt gives grounded chat, notes, and search, but lacks Lateral's literature-review-specific screening, extraction, and evidence-organization workflow.
setupDocker is the first hurdle, followed by supplying at least one provider API key or setting up Ollama and assigning models to the required roles
