BUILT FOR LAW FIRMS

Your AI, briefed on every matter.

Deepmatter keeps a living memory of each matter and briefs whichever AI you ask, such as Claude, ChatGPT, Gemini, or Copilot. Answers arrive specific, current, and cited. And what one matter teaches is there for the next.

You control the memory

Every matter teaches your firm something.

Deepmatter remembers it.

WHERE IT FITS

Deepmatter knows what you're working on. And what came before it.

Deepmatter gets to know each matter as you work it. Ask an AI tool for help and Deepmatter hands it the relevant context and precedents. The first thing you notice is that the answers stop being generic.

No prepping it: It follows the work in the background. You never tag or paste a thing. Open it any time to see what it knows.
Evidence on every answer: Every response lists the emails, conversations, and documents behind it.
It has seen this before: Deepmatter remembers how the firm handled the same point on earlier matters and brings that in.

In practice

Same question. Very different answers.

A task lawyers run every day, asked twice. Once with the agent on its own, once briefed by Deepmatter.

You ask

Draft a reply to opposing counsel on the indemnity cap.

Without Deepmatter

Claude, on its own

Here's a draft: 'Thank you for your markup. We have reviewed the proposed adjustment to the indemnity cap...' Parties typically address a known exposure through a price adjustment, an escrow, or a specific indemnity. If you can share the draft and the correspondence, I can tailor this to your negotiation.

Thank you for your markup of August 12. Our client cannot accept a price adjustment for the identified exposure. The structure discussed on August 3, a twelve month escrow with the cap unchanged, addresses the risk appropriately. If it assists in closing this point, our client is prepared to move on timing.

You ask

Get me ready for the 4:30 call with the mediator.

A solid mediation prep covers three things: your walkaway, the other side's likely range, and the concessions you can trade. If you tell me the offer history and your authority, I can make this concrete.

Where it stands: claimant at 90k since Tuesday; your authority is 75k plus the agreed reference, a 15k gap. Reinstatement is off the table per the mediator. Tradeable: reference wording and payment timing. Suggested opening: 62.5k with the reference offered early.

Hi Priya, a quick update on the round. Investor counsel cleared the charter on Thursday, and your board consents came in yesterday. Two items remain before closing: the IP assignment, which is with us, and the bank consent, which we expect this week.

FAQ

Get in touch

What if I'm not using any other AI tool yet? Can I just use Deepmatter?

Yes. Deepmatter works on its own: ask it directly and it answers from your matters with sources. If you pick up other AI tools later, the memory is already there waiting for them.

I use Claude for some things and Copilot for others. Does it work with both?

Yes, and that is the point. Many lawyers already bounce between tools. The memory sits under all of them, so what Claude learned about the matter this morning is there when you ask Copilot this afternoon.

Don't Claude and ChatGPT already remember my conversations?

They remember something, but not the way a lawyer needs. General memory is one undifferentiated pile, with every client and every conversation blurred together, and only inside that one app. Deepmatter organizes memory the way you organize your practice: matter by matter, each one kept separate, visible, and under your control, behind whichever AI agent you use. And what a matter teaches does not vanish when the chat ends or the lawyer moves on. It stays with the firm.

Do I have to change the way I already use my AI chatbot?

No. You keep asking exactly the way you do now. What changes is what comes back: answers that already know the matter, with the sources listed underneath.

How does this compare to things like Harvey or Legora?

Harvey and Legora give you a new place to do legal work with specialized workflows inside. Deepmatter keeps you where you already work and adds the missing piece: a memory of your matters and of your firm's precedent, for whichever AI you use. For most firms the context was the missing piece.

How does the firm's memory get built?

It starts with what the firm values most, its precedent libraries and the sources it chooses to bring in first. Then it grows on its own as lawyers work new matters.

Is any of my data used to train AI models?

No. Nothing you connect is used to train any model, ours or anyone else’s. Your memory is encrypted, scoped to you, and used for exactly one thing: briefing your own AI on your own matters.
