Fast-read signals for fit, pricing, and trust.
Start with where your images live: AltText.ai publishes connectors for eight named platforms, plus browser extensions and an API. Then look at whether your backlog is a one-off sweep or a steady trickle, because the annual arm grants the whole year's credits at the start rather than releasing them monthly: Silver at $189 a year hands over 6,000 credits on day one. The trap sits next to that. Unused plan credits roll forward only on a normal renewal, and changing plan forfeits that period's unused credits — so size the tier for the backfill you have before you start it, not halfway through.
AltText.ai does one job. It generates alt text for images, in bulk, and it is built around reaching images where they already live rather than around a single upload box. The route in is either a platform connector, a browser extension or the API.
The unit of cost is a credit, and the arithmetic is worth doing before you choose a tier. A standard image costs one credit. An advanced format — AVIF, HEIC, SVG or TIFF — costs two, and those formats are available on paid plans only. Every additional language costs another credit per image. So a 4,000-image store that wants English and Spanish is an 8,000-credit job, not a 4,000-credit one, and more than that if the photography is stored in a modern format.
The ladder runs Bronze, Silver, Gold, Titanium and Platinum at $5, $19, $59, $119 and $229 a month, carrying 100, 500, 2,000, 5,000 and 10,000 credits respectively. Each is also sold annually, and the annual arm behaves differently rather than simply costing less: the full year's allocation — twelve times the monthly number — arrives at the start of the period. For a backfill, that is the whole point.
The rule that catches people is rollover. Unused plan credits carry forward only when the plan renews normally, with no plan change. Change plan and that period's unused plan credits are forfeited. The practical consequence is that starting small and upgrading when you run out is the expensive path through this pricing, and buying the tier that matches your actual backlog is the cheap one.
Top-up packs are the exception to all of that: 50 credits for $3, bought once, outside the subscription cycle, and unaffected by a plan change. They are sized for the last stretch of a job rather than for the job itself.

Aggregate community sentiment, summarized — not native reviews.
Across YouTube and Product Hunt, a question recurs before purchase: does this work outside WordPress? Five separate accounts across five different threads ask it — about Google Business Profile listings, about sites built without a CMS. These are doubts raised before buying rather than reports of a limitation, and they establish nothing about what the product does or does not support. They are worth knowing for a narrower reason: platform fit is something prospective buyers raise repeatedly before signing up, and it is a question that already has a published answer. Eight platforms are named on the pricing page, with browser extensions and an API behind them. Check yours against that list before you evaluate anything else about the product.
What you can actually do with this tool.
WordPress, Contentful, Dato CMS, Storyblok, Shopify, WooCommerce, Magento and BigCommerce are named on the pricing page, alongside browser extensions and an API. This is the first thing to check, because it decides whether captioning your library is a one-click sweep or a small engineering project.
Annual plans hand over twelve times the monthly number at the start of the period rather than releasing it month by month. For a backfill that is the difference between finishing this week and finishing next year.
Unused plan credits carry into the next period only when the plan renews normally on its regular cycle with no plan change. Upgrading mid-project forfeits what you have not spent, so the cheap tier you picked to start with can cost you more than the right one would have.
50 credits for $3, bought as a top-up rather than a subscription, and they survive a plan change. That makes them the safety valve when a sweep overruns its estimate.
A standard image is one credit; advanced formats (AVIF, HEIC, SVG, TIFF) cost two and are paid-plans only; each additional language costs one more credit. A multilingual store's real credit requirement is a multiple of its image count, not equal to it.

Every new account starts with 25 free credits and no credit card is required. That is a one-off starting grant to try the product, not a recurring free allowance — there is no standing free tier.
