Use case · Research
Research that reads everything and keeps its sources.
Good research means reading everything, checking the figures against each other and keeping the citations. Sentinel does all three across your own files and the web, and saves what it read so the next question starts where this one ended. Every claim keeps the page it came from.
$ sentinel research ./sources --cite --keep Reading 12 sources … Cross-checking figures … 12 / 12 Flagged 2 figures that disagree Saved to knowledge base: 12 documents Wrote battery-brief.md · sources.bib
How it fits together
Three pieces, one platform
The same model, the same rules and the same runtime, pointed at this kind of work.
Reads everything you give it
PDFs, papers, web pages and your own notes, read in full rather than skimmed, with long sources split and summarised in order.
Keeps every citation
Each claim in the brief points back to the page it came from, and figures that disagree are tabled instead of averaged away.
Remembers for the follow-up
Sources go into your knowledge base, so a follow-up question next week cites the same pages without reading them again.
Structured output
Straight into your pipeline
Briefs, claim tables and citation files come out clean, so the research drops straight into the next document, deck or analysis.

Across the work
The research a chat window leaves half-done
Literature reviews, market scans and your own archive all need more reading than one chat reply holds. Switch tabs to see each one.

From your knowledge base
An example run: every source read in full and cross-checked, with the citations kept beside each claim.
Live view
Research that shows its work
Every source is read and checked against the others, and the trail is kept, so a reviewer can follow any claim back to the page it came from.
FAQ
Questions, answered
How is this different from a chat assistant?
It reads every source in full, works across your own files as well as the web, keeps citations per claim and saves what it read for next time.
Is my research private?
Yes. Sentinel and its knowledge base run on your own machine. Your sources and notes are not uploaded to us.
Does it cite its sources?
Every claim points to the source and page it came from, and conflicting figures are shown side by side.
Can I ask follow-ups next week?
Yes. Sources are saved to your knowledge base, so follow-ups cite the same pages without fetching them again.
How is it priced?
Free to start. Pro at $20 a month covers everyday research. Max adds parallel agents in one call for large reviews.
