Sofii w końcu się udało. Po wielu semestrach dzielenia pokoi w akademiku z obcymi ludźmi, którzy zostawiali brudne naczynia w zlewie i puszczali muzykę o nieludzkich porach, wywalczyła sobie jedynkę. Własna przestrzeń. Własny grafik. Własna błoga prywatność, której nikt nie zakłócał.
Trwało to tylko jedno lato.
— Och! Przepraszam, przepraszam! — powiedziała nieznajoma angielskim z akcentem, najwyraźniej tak samo zaskoczona jak Sofia. — Chyba… to mój pokój? Numer 811?

How we handle dataSecurity you can check
Hosted in Germany, in Hetzner’s ISO 27001-certified data center. Every sub-processor is listed, and a DPA is one email away.
All sub-processorsGive it context
Glossaries, styleguides, translation memory and per-string notes go with every request. You set them up once per project.
GlossariesYou’re the human in the loop
The AI drafts; you decide. Review every change side by side, keep or revert it, and send a review link when a client needs to look.
Review linksAPI, MCP and webhooks
The full API on Starter and Pro. Connect Claude or another AI assistant over MCP, or start runs from your own tools.

Large catalogs, custom workflows, a DPA for procurement. Transept stays self-serve; write to us for the rest.
[email protected]A working day, in five steps
I.Drop in any document, see it translated
Upload a DOCX, EPUB, MD, TXT, or PDF file, or paste plain text. It splits into blocks in a side-by-side editor, and you choose the target language as you import it.
II.A glossary per client that keeps terms consistent
Build it once and switch it on for each project. The client’s terms stay the same from page 1 to page 500, in one language or in twelve.
III.A styleguide that steers every rewrite
Tone, rules, and conventions for each client, generated from a sample page, then versioned and reused. When you re-translate a sentence with a direction ("more formal," "keep the metaphor"), the styleguide steers the rewrite so the result stays in the client's tone.
IV.Literess, your second reader
A literary editor at your side. She reads the translation and flags where the meaning has drifted, the rhythm has gone flat, or the tone has slipped: the small misses that creep in after twenty pages of editing. She also remembers your projects and preferences from one document to the next.
V.Proofread before you deliver
A final QA pass that catches what a tired reader misses: inconsistent terminology, missed glossary terms, slips in style. Run it on a selection or on the whole document.
Simple pricing
Every plan comes with monthly credits. You spend them only on AI work, at the price each action shows before you click. No sales call and no contract: start free and add a credit pack whenever you need more.
One credit covers one source word in Standard mode. Pro mode uses a more capable model and costs 3 credits per source word. Chinese and Japanese source text is counted per character. Manual edits, exports, comments and translation memory are free: you spend credits only when AI translates, rewrites or checks your text, or reads a document to build a glossary or styleguide. Every paid action shows its price on the button before you click. See the price list.

Prices are in euros and exclude VAT. If VAT applies to your purchase, checkout shows it before you pay, and a business with a valid EU VAT ID pays the net price under reverse charge. You can buy credit packs on any plan, including Free: 30,000 credits for €19, 100,000 for €55 or 300,000 for €149. Pack credits never expire. Creating a team and inviting people is free. To share credits, add two or more seats: each seat adds its plan’s monthly credits to the team’s pool, all on one invoice. Cancel anytime and keep your plan until the end of the period you’ve paid for. We give refunds for faults on our side that we can’t fix and for billing mistakes, and EU consumers can withdraw within 14 days and get back the unused part.

Nothing could translate what we wrote — so we built what could
Two writers, one problem.
— Vitalii.I wrote 120,000 words of satirical romance fantasy: mages drowning in debt, a multiverse economy that makes Wall Street look ethical, and a love story tangled up in all of it.
— Mariia.I write semi-fictional stories about real people, built around how it felt. Most of the people I wrote about were foreigners. We met in English, spoke in English, lived those moments in English. So I wrote them that way too.

“But I sometimes wonder what version of them I missed by not writing them in their language.”Mariia
— Vitalii.The same flatness hit me from the other side. Every tool I tried preserved the words but killed the voice. Tone, rhythm, wit, emotional texture: nothing held. It all came back flatter than it went in.
— Both of us.So we did what we know how to do. We read the machine-translation papers. We benchmarked Claude, GPT, Gemini, and a handful of open models on the same 50-page chapter and judged them on accuracy, tone, and whether the satire still landed. None of them held all three; each failed in a different way. So we built the tool we wished had existed when we started.
We still use it every day. This site is localized in Transept: every change to its German and Chinese pages goes through the same workflow you'd use.
FAQ
- Upload DOCX, EPUB, MD, TXT, or PDF files, or import pages from Notion and Google Drive. You can export as DOCX or Markdown, or straight to Google Docs or Notion, and an EPUB goes back out as the same e-book. A PDF comes in as plain text.
- Standard mode is fast and accurate and uses 1 credit per source word. Pro mode uses a more capable model for higher-quality output and costs 3 credits per source word. It is usually worth it for literary or nuanced material.
- Nothing already translated is lost, and your balance never goes below zero. If your balance covers only part of a document, you can translate the part it covers and finish the rest after adding a credit pack: Small (30K / €19), Medium (100K / €55) or Large (300K / €149). Pack credits never expire.
- Yes, when something went wrong on our side: a technical fault that blocked your work and that we couldn’t fix within 3 business days, or a billing mistake such as a double charge. Email [email protected] and tell us which document or payment it concerns and what went wrong. If a single job went wrong, we usually return its credits. A preference for different wording isn’t grounds for a refund, which is why the Free plan gives you 5,500 credits a month to try the quality. EU consumers can also withdraw within 14 days of a purchase and get back the part they haven’t used. You can cancel anytime and keep your plan until the end of the period you’ve paid for.
- Both. Add terms by hand or generate a glossary from existing content, then switch it on or off for each translation.
- Yes. Share a document with specific people, comment on any block, and resolve each thread once it is settled. The activity feed shows what changed.
- Yes. Teams and email invites are built in: add your translators, share resources, and manage projects from one workspace.
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.
