TL;DR

DeepL Translator Individual is $10.49 per user per month ($8.74 billed annually); Team $34.49 ($28.74 annual); Business $68.99 ($57.49 annual). The API is a second SKU. Google Cloud Translation NMT is $20 per million characters after 500,000 free. Microsoft Translator S1 standard text is $10 per million; F0 includes 2 million characters a month. Phrase Team is $1,245 per month billed annually. Lokalise Explorer is $149 a month, Growth $379, Advanced $1,049. ChatGPT is a chatbot with a translate prompt, not a product on this list.

5 tools compared: DeepL, Google Cloud Translation, Phrase, Lokalise, Microsoft Translator
Google Cloud Translation (best for: Product and content APIs that need 100-plus languages and a published per-character rate): From $20.00 per million characters after 500,000 free ($10 credit); free tier yes
Phrase (best for: Teams that need documents, app text and machine translation in one platform and can pay a four-figure monthly fee): From $27/month (Freelancer, billed annually); 14-day trial yes
Lokalise (best for: Software and mobile teams that want translation management without paying per translator): From $149/month (Explorer); 14-day trial, no card

AI translation tools are not AI writing tools. Jasper and ChatGPT draft copy in one language. The products here take a source string, a file, or a repo of keys and return another language, with a glossary, a translation memory, or a per-character invoice.

Mixing the two categories is how a team buys Plus seats and still has no TMS.

The invoice splits three ways. DeepL sells seats for people who paste and upload. Google and Microsoft sell characters through an API. Phrase and Lokalise sell a localization platform, then meter words. A screenshot of a translate box does not tell you which bill you are signing.

DeepL

Top Pick

Best for: People and small teams who want the best European-language output and will pay a separate API bill

PricingFrom $10.49/user/month (Individual, $8.74 billed annually); free API tier yes

+Still the default when the pair is EN-DE, EN-FR or another European pair reviewers already trust

+Individual at $10.49 is cheaper than a ChatGPT Plus seat and actually is a translator

+Paid plans are the ones you put confidential docs on, not the free web box

−Language list is short next to Google or Microsoft. A new locale can force a second engine

−Translator and API are two invoices. Teams that assumed Pro included keys find out at checkout

Google Cloud Translation

Best for: Product and content APIs that need 100-plus languages and a published per-character rate

PricingFrom $20.00 per million characters after 500,000 free ($10 credit); free tier yes

+Official page, no seat minimum, 500,000 characters free every month

+Language coverage is why teams pick it when DeepL does not have the locale

+Advanced adds glossaries and batch without a different NMT rate

−It is an API and a console, not a TMS. Keys, reviewers and TM live somewhere else

−$20 per million is twice Microsoft S1 for the same NMT-shaped job

Phrase

Best for: Teams that need documents, app text and machine translation in one platform and can pay a four-figure monthly fee

PricingFrom $27/month (Freelancer, billed annually); 14-day trial yes

+Unlimited TMS seats on Team, so translators are not the meter

+Language AI, NextMT and glossaries sit in the same buy as the CAT editor

+Published Team capacities (words, MTUs, AI units) you can take to finance

−$1,245 a month is $14,940 a year before overage. That is not a DeepL seat

−Business, Enterprise and several CMS connectors are quote-only

Visit Phrase →

Lokalise

Best for: Software and mobile teams that want translation management without paying per translator

PricingFrom $149/month (Explorer); 14-day trial, no card

+Explorer at $149 is an order of magnitude below Phrase Team

+Translator and reviewer seats are unlimited. You pay managers and processed words

+In-context editors, Git and Figma are the reason product teams pick it over a raw MT API

−60,000 processed words on Explorer is small. A busy app will hit Growth or a top-up

−Pro AI words are a tight separate quota. Standard MT and Pro AI are not the same bucket

Visit Lokalise →

Microsoft Translator

Best for: High-volume text APIs on Azure, or anyone who wants the cheapest published machine translation rate

PricingFrom $10.00 per million characters (S1 text); free tier yes, 2 million characters/month

+Half of Google's NMT rate on the same unit, confirmed in the retail price list

+F0 at 2 million characters/month is the largest free API slice here

+Custom Translator exists if you have parallel data and will pay $40 per million to serve it

−Quality on European pairs is why people still keep DeepL next to it

−No TMS. Same gap as Google: memories and vendors live in Phrase, Lokalise or a CAT tool

What it is

An AI translation tool is machine translation, a translation management system, or both. The engine maps source text to a target language. The TMS stores keys, memories, glossaries, vendor tasks and the Git or Figma connector. DeepL, Google Cloud Translation and Azure Translator are engines you call or sit in.

Phrase and Lokalise are the workflow around the engine.

This is not brand-voice blog generation and not a grammar pass. If you wanted those, AIpresso already has writing-tool and chatbot lists, plus a ChatGPT review. Buy those when the job is drafting.

Buy these when the job is shipping German, Japanese or Arabic without retyping the product.

Why it matters

Five DeepL Team seats at the annual rate are about $1,724 a year. Five million characters through Google NMT after the free slice is about $90. The same five million through Microsoft S1 is about $50. Phrase Team is $14,940 a year before extra words.

Lokalise Explorer is $1,788 a year and includes 60,000 processed words. Those numbers are not substitutes for each other.

The other reason is where the text goes. Free consumer translators may keep input for training. Paid DeepL, Google Cloud and Azure are the ones you put a DPA on. A ChatGPT consumer chat is still a chat.

Key features to look for

Billing unit

Per seat, per million characters, or processed words plus a platform fee. This decides year-one cost more than any quality slide.

Engine versus TMS

An API that returns a string is not a queue of keys, reviewers and a memory. Teams that skip the TMS re-translate the same sentence every release.

Glossary and translation memory

Product names, legal terms and UI labels. DeepL Team starts to share glossaries. Phrase and Lokalise treat TM as the product. Raw ChatGPT does not.

Language coverage

DeepL is narrower and usually stronger on European pairs. Google and Microsoft cover 100-plus languages. A second engine appears the day you add a language DeepL does not ship.

What the free tier is for

Google's 500,000 characters and Azure's 2 million are real API allowances. DeepL Free is a personal cap. Phrase and Lokalise free trials expire. None of them is a production TMS.

Pricing

This category bills three ways: DeepL sells seats, Google and Microsoft sell characters, and Phrase and Lokalise charge a platform fee then meter words, with Lokalise also billing advanced seats while translator seats and hosted-word storage stay unlimited on paid plans.

Google, Microsoft, Phrase, Lokalise and DeepL publish USD prices. DeepL Enterprise, Phrase Business, Phrase Enterprise and Lokalise Enterprise are quote-only.

The cheapest character rate is Microsoft at $10.00 per million, the cheapest seat is DeepL Individual at $10.49 per user per month, and Lokalise Explorer at $149 a month is the low end for a team localization platform.

Costs jump at Phrase Team ($1,245 a month billed annually), on DeepL API overage at $27.50 per extra million, and on custom models at Google and Microsoft. Google and Microsoft include a free monthly character allowance, Phrase and Lokalise offer a 14-day trial, and a DeepL translator seat does not include the API.

Mistakes to avoid

×Buying ChatGPT Team seats because people already type 'translate this.' That is a writing/chat bill. It has no translation memory, no key workflow and no per-character SLA. Keep it for drafts. Put shipping strings in a TMS or an MT API.

×Standardising on DeepL Individual and then wiring production to the same login. Translator Pro is not the API. DeepL Help is explicit: API Pro is gone, Growth or Enterprise API is the other product.

×Picking Phrase Team at $1,245 a month for a five-person app that Lokalise Explorer at $149 would have held, or the reverse: staying on Explorer's 60,000 words after the catalog grew.

Expert tips

→Price the engine and the TMS separately. Google or Microsoft for the raw characters, Phrase or Lokalise for the keys. DeepL if reviewers refuse the hyperscaler output on a few pairs.

→Convert words to characters before you compare invoices. A million English words is roughly 5 to 6 million characters. Google at $20/million and Microsoft at $10/million only make sense after that conversion.

→Keep confidential source off free consumer boxes (DeepL Free, ChatGPT Free/Plus). Paid DeepL, Cloud Translation and Azure are the ones with a commercial DPA path.

The bottom line

If the job is a person translating documents, buy DeepL Individual or Team and stop there. If the job is an API in the request path, buy Microsoft Translator at $10 per million or Google Cloud Translation at $20 when you need the language list or the LLM/Adaptive options.

Do not pay DeepL API rates for bulk UI strings unless reviewers have already failed the cheaper engines.

If the job is a product catalog, screenshots and a release train, buy a TMS. Lokalise Explorer at $149 is the on-ramp.

Phrase Team at $1,245 is the all-products floor. ChatGPT belongs on the chatbot and writing lists, not on this invoice.

Frequently asked questions

What is the best AI translation tool for a team?

DeepL Team if people paste and upload and the languages are ones DeepL supports. Google Cloud Translation or Microsoft Translator if the app calls an API. Phrase or Lokalise if you have keys, reviewers and a release calendar. A team that needs all three jobs will buy an engine plus a TMS, not one SKU.

How much does DeepL cost in 2026?

Translator: Individual $10.49 per user per month ($8.74 billed annually), Team $34.49 ($28.74 annual), Business $68.99 ($57.49 annual), Enterprise custom. API Growth has been listed at $26 a month billed annually with 12 million characters a year and $27.50 per extra million. API Pro is no longer sold. Checked 1 September 2026.

Is ChatGPT a good translation tool?

It will translate a paragraph. It will not give you a glossary you share, a translation memory, a key-based workflow or a per-million SLA. Plus is $20 a month for a chatbot. Use it for a one-off sentence. Do not make it the localization stack. See the ChatGPT review and the AI writing / chatbot lists for that product.

Google Translate API vs Microsoft Translator vs DeepL API: which is cheaper?

On published meters, Microsoft S1 is $10 per million characters, Google NMT is $20 after 500,000 free, DeepL API overage has been about $25 to $27.50 per million plus a monthly API fee. Quality and language coverage are the reasons to pay up, not the unit price. Checked 1 September 2026.
