AltText.ai vs Booster AI SEO + AEO Optimizer (2026): which should you pick?

Pick AltText.ai if

• Fits if your store or blog has hundreds of images with no alt text
• Works for multilingual sites that need alt text in several languages

Look elsewhere if

• Tight if you're just looking, as the 25 free credits are one-off and packs cost $3 for 50
• Pricey if you have lots of images, as 2,000 a month is $59 and 10,000 is $229
• Watch out: AVIF, HEIC, SVG and TIFF cost 2 credits and need a paid plan, and each extra language is 1 more
• Watch out: changing plans forfeits that period's unused credits, and used credits are usually not refunded
• Too light for your whole SEO setup, as it only writes alt text

Pick Booster AI SEO + AEO Optimizer if

• Fits if you run a Shopify store and want SEO fixes applied across every product
• Works for stores with big catalogs that are missing alt text

Look elsewhere if

• Tight if you stay free, as it mostly detects problems; meta templates and fixes need Pro at $39 a month
• Pricey if you want image compression or Search Console data, which need Premium at $69 a month
• Watch out: charges come every 30 days through Shopify unless you pay $349 or $619 for the year
• Skip it if your store isn't on Shopify, as it runs nowhere else
