How it works

From filing to insight, at a click.

Use the live demo immediately, or add the Graffiti shortcut to your browser for accounts you work with every day.

1

Open the accounts

Load a Companies House filing, a direct URL, a local iXBRL file or an ESEF report package.

2

Click your Graffiti shortcut

The filing becomes searchable and its facts, sections and company context become available.

3

Analyse accounts and company data

Ask, compare, validate, annotate and export while keeping the original accounts alongside the answer.

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.

Browser-first by design

Practical for public and local filings.

Opening a local file or report package parses it in your browser; the original file is not uploaded just because you open it. If you use AI, Graffiti sends your question and extracted filing content through its authenticated service to OpenAI. Notes stay in browser storage and are not included in AI or Companies House requests. Only use network features on non-public material when you have authority to share that content.
