A memory layer you own.
Bring any AI on top of it.

Aristra builds one brain from the tools you already use and opens it to whatever you ask: Claude, ChatGPT, Gemini, your own agents, or Aristra itself. There is no wall around it. Switch models and the memory comes with you.

Knows your voice

Drafts sound like you, not like a template.

Knows your people

“The invoice with Dana” is enough.

Knows what you decided

Ask why, and get the thread that settled it.

It’s your brain. Open it, edit it, export it, delete any of it. Nothing you do here trains a model for anyone else.

Text it.
Or don’t open anything at all.

Aristra lives in the places you already look. Start on your phone, pick up on your laptop, ask from inside Claude. Same brain everywhere.

Open a doc and write with an agent that already knows the project. It proposes, you accept or reject, line by line. Nothing lands in your draft until you say so.

Machine learning, in three ideas.

Machine learning is the practice of teaching a system to find patterns in data instead of following rules written by hand.

Supervised models learn from labeled examples, mapping inputs to known outputs so they can predict the next one.

Unsupervised learning finds the structure on its own, grouping what belongs together without a single label.

Reinforcement learning improves through trial and error, rewarded each time it moves closer to the goal.

In practice you move between all three, often inside the same project

Also works inside Claude and ChatGPT, so your memory follows you there too.

One memory
for the whole team.

Index your shared drives, wikis and repos once. Everyone on the team gets an Aristra that knows the company, with roles deciding who sees what.

Shared memory, personal drafts.

The team’s wikis, drives and repos in one index. What each person writes stays theirs until they share it.

Roles and invitations built in.

Invite by email, set who sees what by role. Admins decide which sources the whole team can draw on.

Encrypted at rest with keys you can rotate.

Your data is encrypted with keys you control. Rotate them from the admin panel whenever your policy says to.
