Image Voice vs Alt Text Generator AI
Last updated: September 11, 2026
Alt Text Generator AI has one idea we genuinely like: its credits never expire. Buy a hundred descriptions and they are yours until you use them. For a store that adds a handful of products a month, that is a better shape of pricing than a subscription that resets every thirty days.
This page is short, because the listing is short. Everything below is quoted from it.
What Alt Text Generator AI actually does
Generate alt text for all product images using bulk feature
Generate alt text for individual product images directly.
Multiple languages are available including English, Spanish, German, and more
The listing says it uses AI; it does not say whether that means looking at the image or writing from product data, so we will not guess.
Pricing — read the listing yourself
Its plans, as shown on the pricing cards:
| Plan | Price | Credits |
|---|---|---|
| Free | Free to install | Buy credits as needed |
| Basic | $7 / month | 100 |
| Pro | $10 / month | 500 |
| Premium | $30 / month | 1,200 |
One credit is one description, and the listing says "credits never expire" and "unused credits roll over."
Two lines on the same listing are worth reading before you buy. The description says:
We don't like monthly plans or subscriptions, so all of our plans are one-time payment plans.
— while the pricing cards above show each plan as "/ month." And the pricing section notes:
External charges may be billed by AltTextGeneratorAI separately from your Shopify invoice.
We are not suggesting anything by quoting these; we are quoting them because they are the two facts a buyer would most want settled, and the listing does not settle them on its own. Ask the developer which it is before you pay.
Image Voice, for comparison, bills through Shopify: flat monthly prices, charged on your Shopify invoice, cancelled from your Shopify admin.
Where it is better
- Credits that do not expire. No monthly allowance to lose. If your catalogue grows slowly, you pay for exactly what you write.
What is actually different
Image Voice grades what you already have before it writes anything. Every existing description is sorted into missing, junk, weak or good, with a vision-checked sample you read yourself. Alt Text Generator AI's listing describes generating alt text; it does not describe checking the alt text you already have, though it is tagged with Shopify's "SEO score audits" category.
After that, Image Voice reads each image individually, writes what is in the frame, and holds changes for your approval unless you switch on auto-pilot — every one undoable for 30 days, on every plan.

What to do about it
Run the free audit first. It is free, it needs no card, and it tells you how many of your images actually need writing — which is the number you would want before buying credits from anyone, including us.
