Alta review
A focused web tool for contextual alt text, charts, infographics, and CMS exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Alta is a browser-based AI alt text generator for website owners, marketers, and accessibility teams. It accepts PNG, JPEG, WebP, and GIF images, then produces descriptions designed for screen readers. Its focus extends beyond standard image captions: charts and infographics can receive long descriptions and data tables, while contextual generation helps tailor output to the surrounding content. Three alt text styles and 13 languages give users several ways to shape the result.
The published plans show a straightforward freemium structure. Free provides unlimited page scans, all three styles and 13 languages, with no signup. Pro costs $29 per year and adds unlimited generations, bulk upload for 50 images at once, CSV export for CMS workflows, commercial use, and support. Image processing without storage is also part of the product's workflow. This makes the free tier suitable for scanning pages and exploring the available styles, while Pro is the more practical option for recurring production work and larger batches.
Alta also fits websites built with Shopify, Wix, Squarespace, Webflow, or WooCommerce through its listed integrations. CSV export supports CMS publishing workflows, although the product remains web-only and does not provide native CMS plugins. Its strongest fit is a team that needs accessible descriptions for ordinary images plus structured treatment of charts and infographics, without requiring a broader content operations platform. Choose Alta for focused scanning, contextual generation, and small-to-medium batch work; look elsewhere if browser-only access or CSV-based publishing does not fit your process.
