Transept vs Trados desktop CAT vs document-first
No cardFirst 5 pages freeYour work never trains AI
Trados (Trados Studio and the RWS cloud tiers around it) is the tool most professional translation runs through, and has been for decades. Its translation memory is deep (exact, fuzzy, fragment, and upLIFT matches), its plugin library is enormous, its file support is close to universal, and in enterprise, government, and language-service supply chains it’s effectively the default. That depth has trade-offs: Studio is a large program to learn (RWS runs its own courses and certification for it), the flagship is officially supported only on Windows (Trados Go is the browser-based alternative), and only the two freelance plans, Trados Go and Trados Freelance, have published prices. Transept isn’t trying to be a better Trados; it’s built for a different job. Here’s where each one is the right pick.

Trados is for professional and enterprise CAT work: mature translation memory, deep interop, a plugin ecosystem, and a place in LSP and public-sector supply chains that nothing else fully replaces. Transept is for document and content translation that needs to ship now, in the browser, with no segment grid to learn first. Use Trados for the professional CAT program and Transept for the document.
When Transept is the better fit
Nothing to install
Trados Studio, the flagship, is a Windows desktop application. Trados Go runs in the browser, but some work, such as opening project packages or using the AI Assistant, still needs Studio. Transept runs in any browser on any operating system: sign up and translate, with nothing to license, download, or maintain.
No learning curve
Trados Studio is a deep segment-grid CAT environment with decades of accumulated features, and RWS runs e-learning, trainer-led courses and certification to help people master it. Transept is document-first and AI-native: upload a file, translate, review, and export. There’s no segment grid to master first.
Transparent, self-serve pricing
Trados publishes prices for its two freelance plans, Trados Go at £24/month and Trados Freelance at £34/month excluding VAT, each with a 14-day trial. Studio Pro, Team and Business show no price on the pricing page, and Enterprise is sold through sales. Transept is Free, Starter at €29/mo, or Pro at €79/mo, with credit packs that never expire. No sales call.
Memory that remembers the why
Trados translation memory is the state of the art in segment reuse, with exact, fuzzy, fragment, and upLIFT matches. What it stores is the segment. Transept also keeps the reasoning around it, such as the alternatives you rejected and the review comments on a sentence, and feeds that context back to the model. The AI then repeats the decision behind your wording as well as the wording.
4× cheaper model, matched
Give a model the decisions behind past translations, not just their final wording, and it stops guessing. With enough of that context, a model costing a quarter as much matched a premium one on our own benchmarks.
The memory betTrados is built on the segment-grid model of CAT: a document is split into segments, each translated in a grid beside its source, and the translation memory offers matches as you go. Decades of refinement have made that model extremely capable, with strong interop, fragment matching, the plugin AppStore, and package workflows that move work between a language service provider and its vendors. AI arrived later: Language Weaver machine translation first, and now LLM-based generative translation with the model you connect through AI Bridge. The core is still the segment grid, though, and the memory still works by reuse: have we translated this before? Then pull the match. That’s exactly what a mature professional CAT program needs, and it’s why Trados isn’t going anywhere.
Transept starts from the document instead of the segment, and assumes the model is already good (it runs on frontier models, currently Google Gemini). The work happens in the browser, with nothing to install: upload a DOCX or import from Notion or Google Drive, translate with the whole document as context, review with sentence-level alternatives and Smart Proofread, and export back to the original format. The memory goes beyond segment reuse. It keeps the reasoning behind an approved translation (the alternatives you rejected, the review comments) and passes it to the model, and it matches by meaning alongside exact and fuzzy text, so a reworded sentence still turns up. For deep professional CAT work with a package supply chain, Trados is the right tool. For document and content work that has to ship from the browser, with the whole document as context, Transept is. TMX and XLIFF move memory between the two, so using both is easy.

FAQ
- When your work sits inside a professional CAT setup: SDLXLIFF packages moving between an LSP and its vendors, deep plugin dependencies, government or public-sector supply chains, or a mature TM built over years of segment work. Trados is the industry standard there for good reason, and Transept doesn’t replace it.
- Yes. Export your TM from Trados as TMX and import it into Transept. It’s searchable right away, and the AI uses it as reference while it translates. You can export back to TMX or XLIFF at any time, so moving a memory across doesn’t lock you in either direction.
- Trados is the best of classic CAT memory, with exact, fuzzy, fragment, and upLIFT matching perfected over decades. Transept differs in two ways. First, matching: it adds semantic (meaning-based) search on top of exact and fuzzy matches, so a sentence you reworded still comes up. Second, what the memory does: Trados offers matches in the editor and grounds its generative translation in your TMs and termbases, while Transept feeds your matches into the AI draft and the QA pass and also remembers the reasoning behind an approved translation. For deep professional CAT, Trados is excellent; for document and content work, Transept’s memory is the better fit.
- For document and content work, usually not: translation, memory, glossary, QA, and formatted export all happen in one browser workspace. If you’re part of a supply chain that exchanges Trados packages, or you depend on specific Trados plugins, keep Trados for that and use Transept for document-heavy work that doesn’t need a segment grid. TMX and XLIFF move memory between the two.
- For the translation itself, Transept runs on frontier models (currently Google Gemini), enforces your glossary on every pass, and runs a QA pass that re-reads for drift, which works well for documents and content. Trados’s strength is the mature CAT environment around the model, whether that’s RWS’s own Language Weaver or an LLM you connect through AI Bridge. They are different tools for different jobs, and neither simply beats the other on quality.
- For classic professional CAT work (SDLXLIFF packages moving through an LSP supply chain, deep plugin dependencies, a TM built up over years, public-sector interop requirements), Trados is the industry standard and hard to beat. For document-first, AI-native work done in the browser, with no segment grid to learn first, Transept is the better fit. The two are built for different jobs.
- Trados publishes prices for its two freelance plans: Trados Go at £24/month and Trados Freelance at £34/month, excluding VAT, each with a 14-day trial. Studio Pro and the Team and Business cloud plans show no price on the pricing page, and Enterprise is sold through sales. Transept’s pricing is public and self-serve: Free, Starter at €29/month, or Pro at €79/month, with credit packs that never expire. There’s no sales call and no desktop license to buy.
- Yes. Send a review link: the client opens the document in a browser, with no account and no software, and sees the source and the translation. A view link is read-only; a comment link lets them comment under their own name, and they see only that one document. Mark a thread internal to keep your team’s notes out of their view. Links expire after 30 days, and a guest reviewer never takes up a seat.
- No. Transept runs in any modern browser on any operating system (Windows, macOS, Linux, ChromeOS), with nothing to install or license. Trados Studio, the flagship, is a Windows desktop application. Trados Go and the cloud plans run in the browser, though some work, such as opening project packages or using the AI Assistant, still needs Studio.
- Yes. When memory matches went into a translation, the block’s header shows a Memory chip with a count. Click it to see each remembered wording with its match percentage and the document it came from, along with any alternative you rejected for that segment and the reviewer discussion behind it. Each entry is marked Reused, when the output measurably adopts that wording, or Referenced, when the model saw it but wrote something else.
