Synthadoc

Synthadoc is an open-source knowledge compilation engine that processes raw files into a structured, persistent, and local-first Markdown wiki.

Synthadoc acts as a knowledge compilation engine that converts raw documents, such as PDFs, spreadsheets, videos, and web pages, into a structured, persistent wiki. Unlike traditional retrieval-augmented generation tools that summarize data at query time, this system synthesizes information during ingestion to ensure cross-references are built and contradictions are identified immediately. Users manage their data entirely locally, with outputs stored as Markdown files that integrate into environments like Obsidian. The platform includes agentic workflows to handle orphan page detection, verify claims against source material, and manage a document lifecycle. It scales from individual researchers to enterprise teams, operating without proprietary cloud storage to prevent vendor lock-in.
