Free Multilingual Website Translation AI: SeaText AI Translates 125 Languages Automatically

Direct answer

SeaText AI is a free multilingual website translation AI that translates your entire site into 125 languages automatically, with no limits on pages, languages, traffic, or usage. You activate it once and it runs by itself.

How the free translation works

1. One-time install. Add a small code snippet to your site header (works on WordPress, Tilda, Weebly, Thinkific, Webflow, Shopify, and 200+ other platforms).
2. Automatic language detection. SeaText detects each visitor's language before the page loads.
3. Instant translation. The AI translates the page to that language in about 3 ms.
4. Continuous background updates. When you publish new pages, posts, products, or edit headlines, SeaText sees the changes and translates them automatically — no manual requests, no translate button, no page-by-page workflow.

What "free" actually includes

• 125 languages supported
• No page limits, no language limits, no word-count limits, no traffic limits
• Free cloud storage for translated images (upload once, auto-swap per language)
• Free automatic multilingual SEO for every translated page
• Works on dynamic websites and ecommerce stores

Trade-off to know

The free plan gives you a single AI translation per page. The paid plan ($29/month) adds A/B-tested translation variants — SeaText creates up to ten variants per page, tests them, and serves the one with the highest conversion rate and zero errors. If you only need accurate automatic translation at scale, the free tier covers it; if you want conversion-optimized, error-minimized variants, the paid tier adds that layer.
