AltText.ai Review: Automatic Alt Text Generation in 2026

What is AltText.ai?

AltText.ai is an AI tool that automatically writes alt text — the short descriptions screen readers use and search engines index — for your images. Instead of manually describing hundreds of photos, product shots, and blog images, you point AltText.ai at them and it generates accurate, human-readable descriptions in seconds, helping your site meet accessibility standards like WCAG and ADA while improving image SEO.

It is built for anyone who publishes images at scale: bloggers, e-commerce stores, agencies, and developers. It can scan an existing site for missing alt text, fill the gaps in bulk, and keep new uploads covered automatically through integrations or its API — in 130+ languages.

Benefits of Using AltText.ai

Using AltText.ai delivers several clear benefits:

• Accessibility compliance: Descriptive alt text helps your site meet WCAG and ADA requirements, making content usable for people who rely on screen readers.
• Better image SEO: Accurate alt attributes give search engines context, improving image search visibility.
• Huge time savings: Bulk-generate alt text for hundreds or thousands of images instead of writing each one by hand.
• Hands-off coverage: Integrations auto-generate alt text for new uploads so you never fall behind again.
• Multilingual output: Generate descriptions in 130+ languages to match your audience.
• Developer-friendly: A REST API and browser extensions fit it into almost any workflow.

AI Features of AltText.ai

  The core engine analyzes each image and produces a concise, accurate description of what it shows. You can add keywords and context so the output fits your content and SEO goals, and review results before publishing.

  

• Bulk Processing & Site Scan

  AltText.ai can scan your whole site for images that are missing alt text and process them in bulk, turning a huge manual accessibility backlog into a one-click job.

  

• Native Integrations

  With 22+ integrations — including WordPress, Shopify, and Contentful — new images get alt text automatically as you publish, keeping coverage complete without extra steps.

  Built-in quality checks help catch weak descriptions, and newer analysis features assess how well your images are described for AI assistants like ChatGPT, Claude, and Perplexity.

Pricing of AltText.ai

AltText.ai uses a credit-based model where, in general, one credit generates alt text for one standard image (advanced formats may use two). Plans are billed monthly or annually, with annual billing cutting the effective per-image cost:

• Platinum: $229/month (or $2,199/year) — 10,000 credits per month.

There are also one-time credit packs (for example, 50 credits for $3) for occasional needs without a subscription.
