## Which one, for what

### Amazon Translate (B)

Good for: Operators already on AWS who want translation inside IAM and CloudTrail, with S3 batch jobs and terminology files.

Ahead on:
- Reliability, 90 against 55
- Agent ergonomics, 80 against 70
- Security & auth, 75 against 58

Watch for: AWS may store and use text to improve Amazon AI services unless the organisation sets an opt-out policy

### Phrase (B)

Good for: Teams that keep translation projects, term bases and translation memories in Phrase and want an agent to run them, or to translate through engines chosen per language pair.

Ahead on:
- Payments & pricing, 30 against 20
- Maintenance & community, 83 against 25
- Transparency & trust, 74 against 69

Also in its favour:
- Free to start without a card

Watch for: status.phrase.com lists 14 incidents between 10 July and 8 October 2026, two marked critical and ten major, most confined to one component

## Verdicts

**Amazon Translate.** IAM policies scope access per action and resource, with a `TranslateReadOnly` managed policy, and CloudTrail logs each call. AWS may store and use text to improve Amazon AI services unless the organisation sets an opt-out policy.

**Phrase.** Nine APIs with public OpenAPI specs, Markdown docs and a hosted MCP server that signs in with OAuth and separates view, create and delete consents. The status page lists 14 incidents in 90 days, 12 marked major or critical. Capacity top-up prices aren't public, and the terms permit training some models on customer content and prohibit benchmarking.

## Before you call either

### Amazon Translate

1. Chunk real-time text under 10,000 bytes, not characters, so multibyte scripts fit less per call
2. Pass `SourceLanguageCode` auto to detect the source language, and handle `DetectedLanguageLowConfidenceException`
3. Read `AppliedSettings` in the response, since unsupported formality or profanity settings are dropped without an error
4. Retry `TooManyRequestsException` with backoff, which the AWS SDKs do by default
5. Set the AI services opt-out policy before sending private text

### Phrase

1. Exchange a Phrase Platform API token at `https://eu.phrase.com/idm/oauth/token` (or `us.phrase.com`) for a Bearer JWT, which lasts about four hours, and refresh it before it expires
2. Send a `User-Agent` header naming your application on every Strings and TMS call. The Strings API answers 400 without one
3. Keep Strings calls under 1,000 in five minutes and four in parallel, and read `X-Rate-Limit-Reset` and `X-Rate-Limit-Reason` on a 429
4. Send at most six texts of 2,000 characters to `/v2/textTranslations`, with `consumerId` and `targetLang`. Term bases and translation memories work only with an AI translation agent profile
5. Use the MCP URL for the account's region, `https://mcp.eu.phrase.com` or `https://mcp.us.phrase.com`, and ask the user for the view consent alone unless the task writes
