Overview

Audit page copy for accessible text using Chrome on-device AI. No data leaves your browser.

AltSpark scans any page and fills accessibility gaps (missing alt text, vague "click here" links, and generic headings) using Chrome’s on-device AI. It’s private, fast, and reversible. Why AltSpark? Many pages still ship with images without alt text and unclear labels. AltSpark gives you clear, human-sounding descriptions in one click, and no data leaves your browser. What it fixes: 🖼 Images: generates descriptive, context-aware alt text. 🔗 Links: rewrites vague text (e.g., "Read more") into meaningful labels. 🧭 Headings: suggests clearer, scannable headings that improve page structure. How it works: - Scan: run an audit from the popup or Side Panel. - Quick Fix: apply safe fixes in one click. - Auto‑mode: automatically applies safe fixes as you browse (per‑site control). - Right‑click "Describe this image": get a copy‑ready alt description on demand. - Undo/Export: revert instantly or export findings for developers. Key features: ⚡ On-device AI (no cloud calls; works offline once available). 🌍 Language-aware: detects page language; can localize suggestions. 🧪 Preview & Undo before/after, plus optional Export of findings. 🧩 Works anywhere you browse — no site access or logins needed. Technical information: - Uses the new Chrome Built-in AI APIs. - Uses Gemini Nano multimodal functionalities.
