Gems is an AI knowledge assistant that connects your tools, notes, and documents and returns ready-to-use, written-out answers — each one called a Gem — complete with sources, so you can stop manually organizing everything.
Summon Gems with a shortcut and ask anything in your own words instead of digging through folders and apps.
Gems returns structured, written-out answers rather than a list of links, so you can act on them immediately.
Every answer includes its sources, so you can go back and prove where a conclusion came from at any time.
Connect your existing tools in seconds and let Gems index your knowledge without manual filing or tagging.
