Everything you need to transform knowledge
Find everything. Miss nothing.
Three-way retrieval combines semantic understanding, contextual awareness, and keyword precision for 91% recall accuracy.
Built for the most security-conscious organizations
Simple for you. Powerful underneath.
You upload files and ask questions. We handle the complex stuff—organizing, understanding, and keeping everything current—so you don't have to think about it.
One home for everything
Like having one library instead of 50 scattered bookshelves
Your documents, databases, and live data streams all live together. Ask questions across everything at once.
Always in sync
Like a photo album that updates itself
When you update a document, the AI learns immediately. No manual re-syncing, no stale answers, no "did you try refreshing?"
A time machine for your data
Like having a complete audit trail of every change, ever
Need to know what your AI would have answered last month? Or prove what you knew on a specific date? Just ask.
Your data stays yours
Like owning your home vs. renting
We use open standards, not proprietary formats. Export everything, use any tools you want, switch anytime. Zero lock-in.
