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.

Lingo.dev

Lingo.dev suits teams that want glossary and tone control on every translation call, with a published fee of $2 per million output tokens and model costs passed through. It has no public OpenAPI file, its llms.txt is one line, and scoped keys, roles and audit logs are limited to the Enterprise plan.

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

Lingo.dev

  1. Send X-API-Key to https://api.lingo.dev and keep the key server-side. On non-Enterprise plans a personal key reaches every engine its creator can
  2. Use POST /process/localize for one language pair and POST /jobs/localization with an idempotencyKey for several. Pipeline stages run on async jobs only
  3. Treat 402 (credit limit) and 429 (daily token quota) as limits to report, not to retry. Retry 500 with backoff
  4. Read usage.cost on each sync response to track spend. Sandbox stops at 100,000 tokens a day
  5. Connect MCP clients to https://mcp.lingo.dev/account. Its tools can create and revoke API keys and invite members, so ask before those calls
