Use this to eliminate, not crown

Start with a real language professionals and operations teams selecting production and quality tools workflow. Eliminate candidates that fail a deployment, format, locale, accessibility, or exit requirement; then test the survivors with your own content.

  • Write three non-negotiable gates before opening the table.
  • Choose the view that matches the decision in front of you.
  • Open the linked documentation for any field that changes the shortlist.
  • Run one representative import, production, review, and export cycle.

Proof-of-work protocol

1. Import a representative source with placeholders, markup, plurals, and right-to-left text.
2. Route it through translation, review, QA, and correction.
3. Exercise automation or integration under realistic permissions.
4. Export every asset and target file needed to leave.
5. Record defects, manual steps, plan dependencies, and owner responses.

Frequently asked questions

Do we still need a CAT tool when using machine translation or an LLM?

Usually yes for professional production. CAT environments preserve segmentation, tags, bilingual review, translation memory, terminology, QA, file reconstruction, and auditable handoff. AI can assist a step without replacing those controls.

Why are QA tools listed beside CAT tools?

They solve different layers. A CAT tool produces and reviews bilingual content; a dedicated QA tool can inspect many files for consistency and terminology. The comparison identifies complements as well as alternatives.

What should we test before buying a CAT tool?

Round-trip your hardest real file and an external package, apply terminology, run QA, test a complex-script target, and export TMX plus the target. Reject a tool that damages the source format or traps essential assets.

How this was built

Admas reviewed current first-party product documentation against criteria specific to this tool category. A missing claim is recorded as not established, not scored as a failure. Entries describe documented product capabilities, not plan entitlement, implementation quality, security posture, or suitability for a particular organization. Re-run the proposed proof-of-work and export test before procurement.
