Best AI translation tools 2026: independent ranking
We rank machine and AI translators for texts and documents by verifiable facts only: what happens to your texts on the paid plan or API, how many languages are supported, document translation, glossaries, offline mode, the price of the cheapest plan and App Store reputation. Every fact links to the official page it comes from and carries the date we checked it. Paid placement never changes the Score.

Not ranked yet: not enough verified data
These services are known to us, but we haven't verified enough facts to rank them fairly.
- Baidu Translate (46% backed by facts)
- Mate Translate (36% backed by facts)
- Reverso (site closed to automated checks, )
- SYSTRAN Translate (58% backed by facts)
- Smartcat (43% backed by facts)
- Yandex Translate (site closed to automated checks, )
- iTranslate (28% backed by facts)
Sites marked as closed refuse automated reading (403 error, captcha or a robots.txt ban). We don't bypass such protection, so we can't verify their facts and they are not ranked. This says nothing about their quality. A company can send links to its official pages to [email protected].
How we calculate the Score
30%
Privacy
Whether the vendor states that texts sent on its paid plan or API are not used to train models and are deleted after translation, and whether it holds ISO 27001 certification.
30%
Features
The officially stated number of languages (log scale, full credit at 250), translation of whole documents with layout, glossaries, a developer API and offline mode in the apps.
20%
Price
Whether a free plan exists and the monthly price of the cheapest paid personal plan: $0 (free-only services) scores 100, $30 or more scores 0.
20%
Reputation
App Store rating (US): 3★ scores 0 and 5★ scores 100, damped when there are few ratings (full weight at 1,000,000); plus the company's track record (15+ years gets full credit).
How to choose a translation tool
Check what happens to your texts
Before you paste contracts, medical records or client data, find out whether the service keeps your texts and uses them for training. Rules often differ between the free version and paid plans.
Make sure your languages are covered
Language counts range from a few dozen to more than 200. Check that your exact language pairs are supported — rare languages often work only in one direction or with lower quality.
Translate files, not just text
If you work with Word, PDF or PowerPoint files, choose a service that translates whole documents and keeps the layout. Check the file size and monthly file limits of the plan.
Use a glossary for recurring terms
Product names, legal terms and company jargon should be translated the same way every time. A glossary saves hours of manual fixes on long or repeated documents.
Have important texts reviewed
Machine translation can be fluent and still wrong. For contracts, official documents and anything you publish, have the result checked by someone who knows both languages.
Frequently asked questions
Which translator is the best right now?
The one at the top of the ranking above has the highest Score by our public methodology. The best choice for you depends on what matters most: privacy for business documents, the number of languages, offline use or price — check the factor bars and pick the leader in that factor.
Is it safe to translate confidential documents online?
It depends on the service and the plan. Several vendors state that texts on paid plans or the API are deleted after translation and not used for training, while free versions may keep or reuse texts. The Privacy facts of each service link to the official page that says so.
Is there a good free translator?
Yes. Most services in this ranking have a free plan or a free app, usually with limits on characters, files or features. The “Free plan” fact shows what we found for each one.
How do you rank translation tools?
By facts from official pages, each with a link and a check date, combined by a fixed public formula. We do not grade translation quality by hand, so the ranking is reproducible and cannot be bought.
