Transept vs memoQ professional CAT vs document-first
memoQ is one of the most respected professional CAT tools — built by translators for translators, with deep translation memory and terminology, LiveDocs, and an on-prem option that regulated buyers rely on. Transept is a different shape: browser-based, AI-native, document-first, self-serve. Both are excellent at what they’re for; the honest question is which surface your work actually lives on.

memoQ — memoQ translator pro on the desktop, plus a TMS available as cloud, private-server, or on-prem — is one of the most respected professional CAT tools, with a heritage summed up by its own line, "created by translators for translators." The translation memory and terminology are deep, LiveDocs and Muse are genuinely useful, AGT brings LLM-based adaptive translation, and the on-prem option matters for regulated buyers who can’t use cloud. The trade-offs are the familiar CAT ones: a steep learning curve, subscription-only pricing (translator pro around €396/year and the TMS from roughly €2,904/year), a web version less mature than the desktop, and AI bolted onto a segment-by-segment TM paradigm. Transept is a different shape — browser-based, document-first, self-serve. Here’s how to tell which fits your work.
Segment-by-segment CAT vs document-first workspace
memoQ is for professional CAT and language operations — deep TM and terminology, LiveDocs, strong interop, and an on-prem option regulated buyers need. Transept is for high-quality document and content translation that ships now, in a browser, without a desktop install or a steep learning curve. Use memoQ for the professional CAT program (especially on-prem); use Transept for the document.
When Transept is the better fit
Nothing to install
memoQ translator pro is a Windows desktop application, and its web version is less mature than the desktop. Transept runs in any browser on any OS — sign up and translate, nothing to license or maintain.
No learning curve
memoQ is deep, and depth comes with a steep learning curve. Transept is document-first and AI-native — upload, translate, review, export. There’s no segment-by-segment grid to learn before you ship useful work.
Transparent, self-serve pricing
memoQ is subscription-only — translator pro is around €396/year and the TMS starts near €2,904/year, sales-led. Transept is Free, Starter €29/mo, or Pro €79/mo, with top-up packs that never expire. Self-serve, no sales call.
Memory that remembers the why
memoQ’s TM and LiveDocs are the state of the art of segment reuse. What they store is the segment. Transept also keeps the reasoning around it — the alternatives you rejected, the review comments on a sentence — and feeds that context back to the model, so the AI repeats the decision behind your wording, not just the wording.
memoQ, like Trados, is built on segment-by-segment CAT: the document becomes a grid of segments, the TM offers matches, and terminology is enforced from term bases as you go. It’s a mature, well-loved implementation of that paradigm — LiveDocs turns past bilingual documents into a living reference, the interop is strong, the support is well regarded, and the on-prem deployment gives regulated buyers a private option nothing cloud-only can match. AGT layers LLM-based adaptive translation on top, but the memory underneath is still segment reuse — Level 1: retrieve the past segment, fill the gap. For a professional running an ongoing CAT program, that depth is the point.
Transept starts from the document instead of the segment, and builds around the model rather than treating AI as a layer on a grid. It runs in a browser with nothing to install: upload a DOCX or pull from Notion or Google Drive, translate with full-document context, review with sentence-level alternatives and Smart Proofread, export back to the original format. Its memory remembers the reasoning behind an approved translation — the rejected alternatives, the review comments — and feeds that to the model, and it matches by meaning as well as exact and fuzzy text so a reworded sentence surfaces. The one thing Transept doesn’t offer is on-prem: it’s EU-hosted cloud, private by default and never used for training. So for deep professional CAT or a private-server requirement, memoQ is the right pick; for document and content work that ships in a browser without a learning curve, Transept is. TMX and XLIFF move memory between the two.
Questions, answered without the fluff
- When you need deep professional CAT — a mature TM and term base, LiveDocs, tight interop with an LSP supply chain — or an on-prem / private-server deployment for regulatory reasons. memoQ is genuinely excellent there; Transept is EU-hosted cloud and doesn’t offer on-prem.
- Yes — export your TM as TMX (and terminology as CSV) from memoQ and import into Transept; the memory is searchable immediately and fed to the AI as reference during translation. Export back to TMX or XLIFF whenever you want to move — nothing is locked in.
- memoQ is the best of classic CAT memory — deep TM plus LiveDocs, with exact, fuzzy, and context matches. Two differences. First, matching: Transept adds semantic (meaning-based) search on top of exact and fuzzy, so a sentence you reworded still surfaces. Second, what the memory does — memoQ fills the segment for you to confirm; Transept feeds your matches into the AI draft and the QA pass, and remembers the reasoning behind an approved translation, not just the segment. For deep professional CAT, memoQ is excellent; for document and content work, Transept’s memory is the better shape.
- No — Transept is EU-hosted cloud, private by default and not used for model training. If your requirement is a private-server or on-prem deployment, memoQ is the right pick for that constraint. For teams that are fine with EU cloud, Transept covers the document workflow without the install.
- On the translation itself, Transept runs on frontier models (currently Google Gemini) with a glossary enforced on every pass and a QA pass that re-reads for drift — strong for documents and content. memoQ’s strength is the mature CAT environment around the model, not the raw model. The honest framing is different tools for different jobs, not one beating the other on quality.
- For deep professional CAT — a mature TM and term base, LiveDocs, tight LSP interop, or an on-prem deployment for compliance — memoQ is excellent and well-loved by translators. For document-first, AI-native work that ships in a browser without a desktop install or a steep learning curve, Transept is the better fit. Different shapes for different jobs, not a head-to-head on the same axis.
- memoQ is subscription-only: memoQ translator pro is around €396/year, and the TMS (server) starts near €2,904/year and is sales-led. Transept is transparent and self-serve — Free, Starter €29/mo, or Pro €79/mo, with top-up packs that never expire. No sales call for the everyday tier.
- No — Transept is EU-hosted cloud, private by default and not used for model training. memoQ’s private-server and on-prem options are a real advantage for regulated buyers who can’t use cloud; if that’s your constraint, memoQ is the right pick. For teams comfortable with EU cloud, Transept covers the document workflow without the install.
- Yes — export your TM as TMX and terminology as CSV from memoQ, then import into Transept. The memory is searchable immediately and fed to the AI as reference during translation; glossaries are enforced on every pass. Export back to TMX or XLIFF whenever you want to move — nothing is locked in.
- memoQ’s TM and LiveDocs store approved segments (and past bilingual documents) and offer them back as matches — the best of segment reuse. Decision-context memory also keeps the reasoning around a translation: the alternatives you rejected and the review comments on a sentence. Transept feeds that back to the model, so it repeats the decision behind your wording rather than just the wording — and it matches by meaning as well as exact and fuzzy text, so a reworded sentence still surfaces.
