9 Best AI Translation Tools of 2026

DeepL is the simplest way for a business to get strong machine translation into everyday work. The Pro plans cover pasted text and whole documents: Individual includes 3 file translations and 300,000 characters a month, Team raises that to 20 files and 1,000,000 characters per user and adds bulk file translation, five glossaries, analytics and single sign-on, and Business allows 100 files of up to 100 MB with unlimited glossaries and translation memory. DeepL states that paid plans do not train on your texts, which matters for legal and HR documents. The limits are the trade-off. File counts are per user and per month, translation memory arrives only on Business, and DeepL is a translator rather than a localization platform, so app teams still need a tool such as Lokalise or Crowdin. Prices on the page we fetched were shown in euros, so the USD price is still pending. For document-heavy teams it remains the easiest place to start.

Weglot is the fastest route to a multilingual website on this list. It reads your site's content, runs AI translation and lets you correct the result in a visual editor, with a glossary, translation exclusions, multilingual SEO, visitor auto-redirection and media translation listed on every plan. The free tier allows 2,000 words and one language, enough to test a small site. Starter costs $17 per month or $170 per year for 10,000 words and one language, Business costs $32 per month for 50,000 words and three languages, and Pro at $87 adds translation and page view statistics plus translated URLs. The catch is how quotas work: the word count is the total unique words across all your languages, it is a fixed limit, and it does not renew each month, so a large catalog or blog moves you up tiers quickly. Weglot does not handle documents or app strings. For a marketing site or online store, it is the least technical choice here.

Lokalise is built for teams that ship software in many languages. Every plan includes unlimited hosted words and unlimited standard seats, document localization and 24/7 support, and the platform adds in-context editors for web and mobile, screenshots and over-the-air delivery so translators see where a string appears. Explorer costs $149 per month with annual billing and suits a first app, with 5 projects, 10 languages, 2 integrations and 240K standard AI or machine translated words a year. Growth at $379 per month removes the project and language limits, adds glossary and translation memory and includes 40K Pro AI translated words a year. Advanced at $1,049 adds style guides, branching, versioning and user groups. That ladder is the main drawback: core translation assets that a growing team will want sit on the second tier, and there is no free plan beyond the 14-day trial. For app teams with a developer workflow, it is one of the most complete options.

Crowdin covers the same ground as Lokalise, localizing apps, games, websites and documents, but with a lower way in. Its free plan supports public projects with 40K hosted words and includes Crowdin AI, Crowdin Assistant and AI Pipeline auto-translation, and non-profit open source projects can request a free license. The paid Pro plan is for private projects starting at 80K hosted words, and the Team plan starts at 500K hosted words with 5 managers, a private workspace, termbase, style guides and context tools. Crowdin lists 700+ apps and integrations, and its mobile SDK delivers translations over the air with real-time preview and screenshots. Managed Balance lets you prepay for machine translation from engines such as DeepL and Google, AI proofreading or professional translators from inside the platform. Note that free plan translations are donated to Crowdin's shared translation memory. The page we fetched showed euro prices, so the USD price is pending.

Google Cloud Translation is Google's translation service for businesses, delivered as an API. The pricing page lists Neural Machine Translation for text, batch text and XLSX files at $20 per million characters after the first 500,000 characters each month, which Google applies as a $10 monthly credit. Document translation for DOCX, PPT and PDF files costs $0.08 per page, custom models trained with AutoML Translation cost $80 per million characters, and the Translation LLM is charged $10 per million characters each for input and output. Language detection is free when you leave the source language blank, and glossary creation carries no charge. For batch jobs, characters are multiplied by the number of target languages, so a five-language run costs five times as much. Like Azure, it needs a developer and a cloud account, and there is no reviewer workspace. It is a good fit for engineering teams that want dependable translation at a low unit cost.

Azure Translator is Microsoft's translation API, and it suits teams that want to translate inside their own software rather than in a separate app. The service covers text translation, language detection, a bilingual dictionary and transliteration, plus document translation and an image translation option. The F0 free tier includes 2 million characters a month. On the pay-as-you-go S1 tier, the US pricing page lists standard text translation at $10 per million characters and document translation at $15 per million characters, while Custom Translation, which trains a model on your own bilingual data, costs $40 per million characters plus training and hosting fees. High-volume users can buy monthly commitment tiers. The weaknesses are practical: you need an Azure account and a developer to call the API, and there is no editor for reviewers. The price table loads through JavaScript, so confirm the rate in the Azure calculator for your region before you commit.

Phrase is the most complete platform here for a company that runs localization as a program. Its business plans bundle Phrase TMS for documents and marketing content with Phrase Strings for software, plus machine translation with custom profiles and glossaries, Language Quality Assessment, vendor management and workflow automation. The Team plan lists unlimited TMS seats, 20 Strings seats, 2,500,000 TMS processed words a year, 12,000,000 machine translation units and 25,000 AI units, with integrations for Figma, Slack and WordPress. Business adds single sign-on, branching, advanced translation memory and unlimited MT profiles. There is also a Software UI/UX plan for product teams and a Freelancer plan for individual translators. The downside is complexity: usage is counted in several units, the Team plan is sold through sales, and smaller businesses may never use most of it. The figures on the page we fetched did not show a currency symbol, so the USD price is pending.

Rask AI is on this list because many businesses now need to translate video, not only text. You upload a video and Rask transcribes, translates and dubs it in 135+ languages, with the option to clone the original speaker's voice in 57 languages and fine-tune each line in an editor. Creator costs $28 per month billed $329 yearly and includes 300 minutes a year, Creator Pro at $67 per month adds multi-speaker lip-sync and 1,200 minutes, and Business at $167 per month adds on-screen text translation, batch uploads, a shared brand glossary and reviewer roles. Rask lets you re-edit and redub without paying again. The limits are worth reading closely: plans are yearly only, minute allowances are annual, and extra minutes at $3 each start on Creator Pro. Rask does not translate documents or websites, so most teams pair it with a text tool. For training videos, product demos and social clips, it is a focused choice.

Smartling sells both the software and the translation itself. The platform includes a CAT tool with visual context, quality checks, workflow and project management, translation memory and glossaries, and its AI Hub routes content through 20+ LLMs and machine translation engines. The plans page publishes per-word service rates: machine translation from $0.0075 per word, AI translation from $0.06, AI human translation from $0.12 and human translation from $0.20 through a network of 4,000+ linguists. The Core plan is free to start and fits small teams translating business documents, but it keeps translation memory for 180 days and offers basic workflows. Enterprise adds customizable workflows, unlimited translation memory, the LQA Suite, a web proxy and the option to bring your own translators, with pricing set by sales. The result is strong for companies that want one vendor for tools and translators, and less attractive for teams that only need machine translation.
