What AltText.ai does
Finds images without alt text and writes descriptions for them, in many languages, through plugins, an API or a browser extension.
AltText.ai generates alt text, the written descriptions attached to images, for websites and applications. According to its homepage, it can scan a site for images that are missing alt text and then produce accessibility-friendly descriptions. Output is available in 130+ languages, and custom SEO keywords can be applied.
For existing libraries, a bulk updater repairs images already on a site, and images can be imported from CSV, Dropbox, Cloudinary or Pinterest. Besides the web interface, the vendor lists a Chrome extension and Firefox AddOn for right-clicking an image, a Developer API, a Webflow app that adds alt text to CMS items, and pre-built connectors for Zapier, Pabbly, Albato and SureTriggers. Advanced image formats such as AVIF, HEIC and SVG are for paid plans only.
Pricing is credit-based, and one credit generates alt text for one image. Every new account starts with 25 free credits, with no credit card required. Paid plans are listed with monthly prices: Bronze $5/mo, Silver $19/mo, Gold $59/mo, Titanium $119/mo and Platinum $229/mo. The homepage gives a yearly example of $49/yr with 2 months free, matching the $5/mo starting price. A credit pack of 50 credits costs $3 with no subscription.
Stated limits: unused plan credits roll over at each renewal, and unused credits stay in the account after cancelling. Changing plans, up or down, forfeits the current period's unused plan credits. The free scanner crawls up to 25 pages, and the homepage demo accepts files up to 16MB.

Pros and cons

Cons
- Advanced formats such as AVIF, HEIC and SVG are for paid plans only

Our take
AltText.ai fits site owners, ecommerce teams and agencies with many images that lack descriptions and who want to automate that through a web interface, a browser extension, a Webflow app, an automation connector or an API. The 25 free credits, with no card, let you check the output on your own images before paying. The trade-offs are that billing is per image credit, so large libraries need a plan sized to the volume, and changing plans mid-period forfeits that period's unused plan credits. Advanced formats such as AVIF, HEIC and SVG need a paid plan. The pages describe the tool only as an alt text generator, so check the pricing page for the credit allowance of each plan before choosing one.
