Start with the evidence.
For everyday decisions.
For research that goes deeper.
For regular analysis and bulk research.
Connect one catalogue. Act on the evidence.
One evidence workspace for a portfolio.
Annual payment in full. SKU allowances reset monthly in UTC. Unused monthly allowances do not roll over. Your checkout shows the currency, annual total and any applicable tax before payment.
Use canonical product evidence in your app, research or workflow. API reads return existing records; catalogue scans capture fresh source evidence. Their allowances are separate. New source captures share a limited capture queue and can pause when capacity is exhausted; API reads of existing records continue.

Scanned SKU allowances limit account usage. Fresh source captures are queued within current shared capacity and are not a promise of immediate throughput. A captured record does not automatically receive a verified score. See category rules and release status →
Real recorded reports, with dates, coverage and evidence limits. Historical snapshots are labelled with their own method version.

Inspect the manufacturer’s material declarations and their exact scope. A component percentage does not describe the whole device.
This product record links to repair and materials documentation. No calibrated overall device score is claimed.

Yes. Install the Chrome extension free and connect your HTT account. Your chosen account plan controls report and catalogue access; the extension installation has no separate charge.

All new paid subscriptions bill annually in the selected currency. Existing subscriptions retain their agreed billing terms. The full annual total and any trial shown by Stripe are displayed before you confirm.
Your saved evidence stays in your library. New requests stop at the allowance instead of creating surprise charges. Upgrade online or wait for the next monthly reset.
Manage billing, invoices and cancellation from your account through Stripe. Review the terms and the cancellation screen for the access end date before confirming.
No. Textiles use the recorded fibre methodology. Devices, ingredients and other categories require their own evidence and calibration. A missing or incomplete assessment stays unscored; payment cannot change a public score.
No. Paid access adds tools and capacity. Every score follows the same recorded category method and evidence rules.
