What it does

One workspace, the whole legal method.

Chat & research

DeepSeek V4.1 Flash by default, plus Qwen, Llama 4, Mistral, GLM, Kimi and Gemma — up to 1M tokens of context.

44 legal skills

Contract review, citation verification, research memos, intake, deadlines, governance and more — loaded on demand.

Legal agents

Contract Reviewer, Citation Verifier, Memo Drafter and Client Intake — each with the method built in.

Provenance ledger

Every claim labelled [AUTHORITY], [REASONING] or [NOT IN SOURCE], traceable to a pin cite.

Documents & search

Upload files, search the web, and keep matter context across sessions.

Private by design

Your own account and storage; no training on your data; human sign-off always.

Why it costs less

Open-source models. Closed-model savings.

We route your work to the best open-source models through one account. On typical drafting and review, that can be a small fraction of the per-token cost of closed frontier assistants — often up to 100× cheaper.

Questions

Is this legal advice?

No. It is an information and drafting tool. Every output is labelled and a qualified lawyer must review and sign off before it is relied on.

Which models can I use?

DeepSeek V4.1 Flash by default, plus Qwen, Llama 4, Mistral, GLM, Kimi and Gemma — up to 1M tokens of context.

Where is my data stored?

In your own account on infrastructure we control, with encrypted credentials and private document storage. You can bring your own model keys on Firm plans.

Can I pay as I go?

Yes — buy credit packs with no subscription and spend them across models and agents.
