Features
Everything the RAG stack needs.
Nothing it doesn't.
Ingest anything
PDFs, DOCX, HTML, plain text. Every document becomes clean Markdown, structured sections, and embedded chunks — instantly queryable.
Retrieve precisely
Hybrid BM25 + vector search with RRF. Section-aware scanning finds the right document before paying for full retrieval.
Ask, get answers
One call to /ask returns grounded, cited answers. Configurable depth from quick lookups to deep multi-document research.
API-first from day one
Project-scoped API keys, org management, and role-based access. The infrastructure layer your whole team can rely on.
Real-time events
WebSocket streams for every document lifecycle event — uploading, processing, sectioned, embedded, ready. Build reactive UIs instantly.
Bring your own model
Use Dewey's managed embeddings or plug in your own models with BYOK. Swap without re-indexing your entire corpus.
How it works
Ship AI search in three steps.
Create a project
Sign up, create an org, and provision a project in seconds. You get live and test API keys immediately — no infrastructure to configure.
Upload documents
POST any file to a collection. Dewey converts it to Markdown, extracts a section hierarchy, chunks it, and embeds everything in real time.
Query and ask
Query for hybrid search results with full citation lineage back to the source, or ask for a grounded answer synthesized at any research depth — from a quick summary to a deep cross-document analysis.
