For translators

The tools are free. The evidence is yours.

Professional tools without ransom: a full CAT editor you don't have to buy — translation memory, terminology, and live quality checks on every segment. Work arrives as offers you can read and counter, ranked by real fit rather than auctioned to the cheapest bid. Your translation memories and glossaries stay yours to keep and export, and the quality checks are your evidence, not a rate lever: deterministic, inspectable, the same verdict for the same text.

In-editor translation memory and QA loopA segment receives translation memory matches and machine translation suggestions, the translator edits it, live QA detectors check the result and offer auto-fixes, and the confirmed segment is written back to the translation memory.SegmentSuggestTM match · MTEdittranslatorLive QAtags · numbers · termsConfirmauto-fix appliedconfirmed segments update the translation memory

The editor

Professional CAT tooling, no licence fee

Translation memory, terminology, machine-translation suggestions, and live QA hints, on the segment, while you type. Term matching is lemma-aware in around 35 languages, spellcheck covers 13 European languages, and Finnish translators get dedicated spellcheck plus real grammar checking, not an afterthought.

You can build and attach your own TMs and glossaries, and export them again as TMX and TBX. Your language assets stay yours.

  • TM matches per segment
  • Termbase highlighting
  • MT suggestions
  • LLM repair chat
  • Spellcheck
  • Finnish spellcheck

Getting work

Offers, not auctions

Work arrives as offers you can accept, decline, or counter — rate, deadline, and the full volume breakdown by translation-memory band, all shown before you commit. Ranking rewards real fit: language pair, service, and domain experience, so the work you see is work you can actually do, and there's no penalty for turning one down.

Your profile in the people directory shows your pairs, domains, and history, visible to the PMs who assign work.

  • Negotiate rate & deadline
  • Counter-offers
  • Translation opportunities for new faces
  • Profile & work history

Quality

QA that has your back

The detectors catch tag mismatches, number drift, and doubled words before a reviewer does, with auto-fixes where the repair is mechanical. Deterministic checks mean no arguing with a black box: the same text always gets the same verdict.

  • Live hints while typing
  • One-click auto-fixes
  • Deterministic checks

Quality estimation

The QE score is your evidence

Our scoring system scores the machine translation before you touch it. When a segment arrives bad, the score says so: proof of what the machine handed you, and of the work your edit added. Quality estimation here is your shield, never a rate lever.
