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.
Open the accounts
Load a Companies House filing, a direct URL, a local iXBRL file or an ESEF report package.
Click Graffiti Bookmarklet
The filing becomes searchable and its facts, sections and company context become available.
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 private filings.
Local files and ESEF ZIP packages are parsed in your browser. Encrypted notes stay in browser storage. AI and Companies House features use authenticated network requests.
