How it works

From filing to insight, at a click.

Browse Companies House filings for free, without an account or installation. Sign in to keep your companies and filings across devices, and to use your paid or Demo licence here.

1

Find a company

Search Companies House by name or number, or paste the link to a filing.

2

Open its accounts

The filing opens with Graffiti running: facts, sections and company context, all searchable.

3

Ask, compare, validate, export

Work on the data while the original accounts stay alongside the answer.

A paid or Demo licence also gives you the Graffiti bookmarklet, which runs the same tools on any filing page or local file. See plans.

Built around the evidence

The accounts stay in control.

A quick answer is useful. A quick answer you can verify is better.

Graffiti works on the filing itself. Click a highlighted value to see what it means, where it came from and which period it covers. AI helps with the first pass; the source remains visible for professional judgement.

How network features work

Know what is sent, and when.

Graffiti analyses the filing in your browser. Opening a hosted filing fetches the source document, Companies House features request published registry data, and signing in syncs the companies and filings you save to your account. When you ask an AI question, Graffiti sends the question and the extracted filing content through its authenticated service to OpenAI. Notes stay in browser storage and are never included in AI or Companies House requests. Use network features on non-public material only when you have authority to share it.
