Start with any filing
Open a local HTML, XHTML or iXBRL file, an ESEF ZIP package, a direct URL, or search Companies House by name or company number.
Product guide
From accounts to analysis.
Open a filing, click Graffiti and choose the level of detail you need. The source document stays beside the tools throughout.
Move through the accounts
Use the generated Contents view to jump between sections. Select a highlighted item to see its concept, value, period, unit, dimensions and accounting reference.
Find the fact you need
Search concepts, values and periods. Filter standard or custom tags and separate tagged facts from figures recovered from the visible table.
Question the filing
Ask in plain English. Graffiti sends the relevant structured facts—and, where available, narrative sections and company context—to the AI assistant.
Put one year in context
Explore multi-year trends, ratios, filing history, directors, significant controllers and company networks. Compare selected returns from up to four companies.
Check, note and export
Run local iXBRL validation checks, trace table rows back to the page, add encrypted browser notes and export CSV, XLSX or XBRL-JSON.
Data screen
Structured access to the whole filing.
Switch between all facts, numeric or text facts, the full iXBRL document, header and resource data, XBRL-JSON and an AI-ready view. Copy exact values or export only the columns you need.
Validation and trace-back
Graffiti flags provable local issues such as missing contexts or units, unparsable values and duplicate facts. Select a result to return to the source item.
Calculations and footnotes
Inspect calculation relationships and move between facts, continuations and footnotes without manually searching the page.
Privacy and access
Know what stays local.
Local filings and ESEF packages are parsed in your browser and are not uploaded merely to open them. Notes are encrypted in browser storage. AI questions send the relevant analysis context through the authenticated Graffiti service.
Made for different working styles
Use dark or light mode, keyboard navigation, visible focus states and colour-independent underline styles for different tag types.
Keep important work portable
Browser notes belong to the document identity on that device. Save an annotated copy before moving a file, changing its name or clearing browser storage.
