About SmaRTL — automatic RTL/LTR by on-device AI

Not yet another RTL toggle. SmaRTL uses on-device AI to detect each paragraph's language and set its text direction — RTL or LTR — automatically, in real time as text appears. No buttons to flip, no whole-page guessing. • Per-paragraph, dynamic: mixed Hebrew/Arabic + English reads correctly, line by line — even as a chat streams in. • On-device AI: detection runs locally using Chrome's built-in AI, with a fast heuristic fallback. No network requests, no data collection, no account. • Automatic on Claude.ai; on ANY site on demand (one click) or via an allowlist (auto-run on sites you choose). • Hebrew, Arabic, and ~30 other right-to-left scripts. • Text only, never layout: it sets the text-direction attribute and leaves the site's structure, menus, and design untouched. • Bonus on Claude.ai: an optional Markdown formatting toolbar for the composer.
