Send a string, a web page or an i18n file to one REST API. AIbit translates the words and leaves markup, attributes, keys and protected values where they were. Name the engine per request, or let the API route it.
Measured on 7 days of production traffic, 6-13 Sep 2026. Latency and success rate on text under 256 bytes.
Free tier with 1,000 requests a month, no credit card. Paid plans from $9.99/month.
Choose any of 249 languages, name an engine or let the API route the request, and read the exact response body. Examples open with responses captured from production; Send runs them again, live, on a shared demo key.

A named engine runs the request or refuses it with 409. It is never swapped for another.
Refusals are answered before quota is counted, so a request the API will not serve costs nothing.

Yes — AIbit actually uses Google Translate, Microsoft, Yandex, and Baidu under the hood. You get the same translation quality at a fraction of the cost. You can even switch engines per request to pick the best one for your language pair.

Free: 5 req/s — Pro: 20 req/s — MEGA: 200 req/s — Enterprise: 300 req/s — Unlimited: 500 req/s. All plans support burst requests. If you need a custom rate limit, contact us for a dedicated plan.
Yes, this is one of our key features. JSON translation preserves all keys, data types, and nested structure — only the string values are translated. HTML translation keeps all tags, classes, and attributes intact, translating only visible text content. Perfect for app localization and website translation.
We do not store or log the content of your translations. Requests are proxied to the underlying translation engines (Google, Microsoft, etc.) and discarded immediately after the response. We only retain basic usage metrics (request count, latency) for billing and monitoring purposes.
We guarantee 99.9% uptime (less than 9 hours downtime per year). Over 7 days of production traffic (6-13 Sep 2026), 99.98% of short text requests were answered successfully. Enterprise and Unlimited plans include priority support with a 1-hour response SLA.
Absolutely. You can upgrade, downgrade, or cancel your plan at any time from your AIbit dashboard at app.aibitranslator.com. No lock-in, no cancellation fees. If you cancel, you keep access until the end of your current billing period.
