Local-first document intelligence
Your documents know more than you think.
Chauncy helps you search, connect, and curate the material you already have: PDFs, email, notes, web clips, and long-forgotten files.
Ask in plain English. Inspect the source. Follow the connections. Chauncy discovers what is related, but you decide what matters.
Mentions the renewal clause, vendor concession, and the email thread from March.
Connects pricing change to the amended service window.
Your note: "This is the clause to challenge if renewal timing changes."
Connected material
Chauncy surfaces evidence. You curate the argument.
Open a source, compare related material, add your own annotation, and keep the trail attached to the document collection.
Private by architecture. Safe by restraint.
Chauncy is not a runaway agent.
It does not browse the web for you, operate accounts, send email, buy things, delete files, or chain together background actions. Chauncy is a retrieval and curation tool for your own material.
Local first
Your documents, search index, embeddings, and annotations live on your machine.
Explicit AI
AI synthesis is optional. You choose the provider, supply the key, and decide when excerpts leave your machine.
Human judgment
Chauncy can surface connections. It does not decide what is true, important, or ready to publish.
Workflow
From scattered archive to usable evidence.
Collect
Bring in PDFs, email, Markdown, Word, PowerPoint, HTML, web URLs, notes, and voice notes.
Ask
Use plain English to search by meaning, not just filename, folder, or exact keyword.
Inspect
Open the source, check the surrounding context, and see related material beside it.
Curate
Add your own annotations, keep the useful trail, and turn discovered material into your work.
Built for serious personal archives
For people who remember the point, not the filename.
Semantic retrieval
Find the memo, quote, email, or note even when you cannot remember the exact words.
Automatic connections
See related material across formats and projects without maintaining a hand-built graph.
Annotations that matter
Attach your intellectual response to source material: disagreement, confirmation, questions, and next steps.
Your AI boundary
Use local search without an API key, or opt into cloud/local AI synthesis only when you choose.
