Compose length-correct image alt text and clean SEO filenames offline, then paste into any editor. No uploads, no accounts. Write consistent, length-correct image alt text and clean SEO filenames in seconds - without uploading a single image. AltSmith is a fully offline composer. You fill a few descriptive slots (subject, attributes, brand/context, location) and it assembles concise alt text within your target length, plus a lowercase, hyphenated, junk-stripped filename like blue-ceramic-coffee-mug-handmade.jpg. Then it pastes the alt text straight into the focused field of your editor, with a one-click clipboard fallback. It is NOT an AI image describer and never uploads your images. It is the fast, offline, length-correct assembly + paste step that turns a per-image chore into a few keystrokes. WHAT YOU GET - Live character counter that warns past your target length (green/amber/red). - SEO filename generator: lowercase, hyphenated, diacritics stripped, word-capped. - One-click paste into the focused alt-text field, with adapters for common editors and a generic fallback for any standard web field. Clipboard fallback when a page can't be scripted. - Reusable templates for different contexts (blog hero, product photo, listing). - Page scan that lists every image on the current page missing or with empty alt text - click an entry to jump to and highlight it. - Adjustable length targets. - Local JSON backup: export and import your templates and settings. PRIVATE BY DESIGN - No accounts, no sign-in. - No image uploads. - No network requests - everything runs locally in your browser. - Your templates, settings, and inputs stay in local storage and are never transmitted. WHO IT'S FOR Bloggers, Etsy/Shopify/eBay sellers, affiliate and real-estate site editors, and anyone adding many images a week who needs concise, consistent alt text and clean filenames - fast, and without burning an upload quota. HOW IT WORKS Open the side panel, pick a template, fill the slots, watch the preview and counter update live, then Copy or Paste. The first time you paste or scan on a site, Chrome asks once for access to that site; granted per-site, never broadly.
