New features
A card for every scanner rule
Every rule axe-core checks — 104 of them, the experimental and retired ones too — has a card. Its face says what goes wrong in plain words, its severity and status, who owns the fix and how an audit catches it, with the rule's ID as the scanner reports it.
Open a card and it unfolds like a map: why it matters, who it affects and how hard, the business impact, each fix as a Do and a Don't in code with what a screen reader says, and a quick test you can run in thirty seconds.
Explore the A11Y Cheat SheetFind the one your scan raised
Paste a rule ID or the scanner's message into the search, and what matched is marked on the cards — with a snippet when it's something the card's face doesn't show. Narrow the deck by theme, severity, WCAG level and version, who owns the fix, how an audit catches it and status; a sentence says what you're looking at, and any part of it comes off with a click.
My Learning
Press the (+) on a card to put it on your learning queue, and the (✓) once you've mastered it. Your queue and your mastered skills sit above the filters, with a gauge of how far through the deck you are; download either as one PDF. It's kept in your browser — nothing to sign in to.
WCAG 3.0 draft cards
Choose WCAG 3.0 under WCAG Level & Version for W3C's Working Draft of 10 September 2026, a card for each of its 46 guidelines. Open one for Core Purpose, Key Requirements in the draft's own words, and Key Takeaways. It's a draft: nothing on these cards is something to pass or fail yet, and each links to its place in W3C's draft.
Filters your way
Drag the filters into the order you use them — kept in your browser — and sort the deck by severity, theme, rule ID, WCAG level, the newest in WCAG or the most recently reviewed. The sentence above the cards says what you're looking at; take any part off with its ×, or Clear it all.

Read aloud, PDF and phone
Read aloud reads a card as it's laid out, outlining what it's reading and keeping it in the middle of the window; skip a panel at a time, or jump to any. Save any card — or a whole collection — as a PDF laid out for A4. And it all works on a phone: filters behind a button, a swipe to move along a card.
