About Alesis

We are Alesis.ai Limited, a software company based in Chester. We build Alesis for the research, evidence and drafting that sit behind UK legal work.

Our starting point is the person reviewing the work. An answer needs sources they can read. A finding needs a page they can check. A draft needs room to be challenged before it goes out.

How we build Alesis

These decisions shape what you see in the product, from opening a citation to reviewing a draft.

Keep the source beside the answer

Citations open the document, decision or provision behind a point. Matter documents retain their page references, so you can read the passage in context before relying on the answer.

Document pages, cited passages and official sources.

Make missing evidence visible

If a document page cannot be read, it is flagged. If the available material does not support a point, the answer should identify what is missing. A gap needs your attention, not a more fluent sentence.

Unread pages and unsupported points are surfaced for review.

Give you ways to challenge a draft

Council reviews work through simulated perspectives, including a counterparty, an ombudsman or a tribunal judge. You can inspect the objections, revise the draft and decide what to use. The review is a simulation, not a decision or prediction.

You review, approve and send the work.

Keep access tied to the matter

Information is held in the UK and processed in the UK and the EU. Firms are kept separate, and people inside a firm see only the matters they are on. Your work is never used to train anything for anyone else.

The same boundaries apply to papers, questions and drafts.
