  • Building an AI research copilot that catches its sources lying
    Research tools forget across sessions, and they never notice when two sources disagree. Crosscheck is a small copilot on top of cogneethat does both: persistent memory of everything you feed it, and a hero feature that flags when sources contradict each other โ€” e.g. "FooDB sustained 50,000 req/s" (2021) vs "only 10,000 req/s" (2024). - Source: dev.to / about 1 month ago

    Looks nice! Would wait for the documentation to learn more. How does this compare to Notesnook?
