Five real supplier documents — test TSK yourself
Download a document, upload it to TSK, and see exactly how we extract, verify, and surface every number — including where we honestly say “review this”.
Clean UK Electricity Bill
Happy-path extractionA straightforward UK electricity bill. TSK should extract meter number, consumption in kWh, billing period, and total cost without ambiguity.
Download PDFUK Gas Bill
Multi-fuel showcaseA standard UK gas bill with MPRN, volume in m³, and unit rate. Tests TSK's multi-fuel handling alongside the electricity bill.
Download PDFMulti-Meter Water Bill
Complex aggregationThree sub-meters (factory, canteen, car wash) summed to a single billing period. Tests TSK's ability to aggregate across sites.
Download PDFMessy Electricity Bill
Honest-failure / needs-reviewA deliberately ambiguous bill with merged-cell charges and a smudged row. TSK should produce a 'needs your review' flag rather than a confident wrong answer.
Download PDFSustainability Narrative Report
Different document typeA 3-page narrative report with Scope 1 + Scope 2 GHG inventory and other indicators. Tests TSK on a document type beyond utility bills.
Download PDFTry the questionnaire
After you upload, TSK pre-fills the CDP Climate questionnaire from your evidence with source-attribution badges on every autofilled slot. Quantitative fields (emissions, consumption) fill automatically; qualitative prompts surface the right evidence snippets so you write with confidence. Sign in to try it.
