Product changelog

Every entry names a page you can open. An announcement with nowhere to point is an announcement about our internal life, so this list cannot contain one — a test fails if any entry links somewhere that does not exist.

Looking for when platforms changed their caption requirements? That is a different record: platform requirement changes.

    Answer pages for the compliance questions

    Four guides on evidencing ADA Title II captions, filling in the caption rows of a VPAT, the FCC's four caption quality standards, and checking captions against WCAG 2.1 AA. Every coverage claim on them is generated from the engine's own registry, so a page cannot claim the product settles something it does not.

    Conformance receipts and a sample anyone can read

    A signed, per-asset record of what a caption file was checked against, which version of which standard, and the result per criterion — including the criteria that could not be evaluated and why. The sample is generated through the production engine on every page load rather than being a fixture.

    Conformance reports across a library

    The roll-up a procurement team actually asks for: across everything you publish, which criteria do you meet. Maps onto VPAT conformance levels without rounding a clean scan up to Supports.

    Public receipt verification

    Anyone can check a receipt, including one we hold no copy of, without trusting whoever sent it. Open and stateless by design — evidence you have to come back to us to validate is not evidence.

    The v1 HTTP API

    Caption processing, conversion and QA over HTTP, for teams that want the check in CI rather than in a browser tab.

    Free caption converter, with delivery presets

    SRT and WebVTT conversion and repair with no account: timing, overlaps, reading speed, encoding, and the platform upload rules that silently reject a file. Eleven delivery targets carry the rules their platform actually enforces, kept separate from accessibility standards because the two answer different questions — what will this platform accept, versus what has to be true of the captions.
