Accessibility Checker for Word: How Accessr Works (Client‑Side, Private)
Published 11 November 2025
Accessr runs entirely in your browser. That means documents never leave your device and no servers ever see your content. Here’s what that looks like in practice:
What the checker covers
- Detects missing or empty alt‑text for images and prompts fixes
- Heading order and structure checks (H1 → H2 → H3)
- Contrast warnings for embedded color styles
- Hyperlink text clarity (flags raw URLs like
http://..) - Basic table semantics (header row detection)
What remains manual (and why)
Certain tasks still require human review, like complex charts or decorative images that need confirmed intent. We surface these in the report so you can triage quickly.
Privacy by design
- No uploads — parsing happens via browser APIs
- No tracking cookies — by default we ship with zero analytics
- Open by default — simple HTML/JS so you can audit how it works
