Comparison
A privacy-first alternative to Google Translate and DeepL for documents
General translation tools are useful, but confidential documents need a clearer data boundary. Veil Translate masks detected and confirmed sensitive entities in your browser before translation. Choose browser-direct BYOK, where masked text and your key go straight to your provider, or the capped managed mode, where masked text is relayed through Veil Translate to a fixed Cloudflare Workers AI model.
Managed translation relays masked body text through Veil Translate to Cloudflare Workers AI. Undetected sensitive data and the remaining body text may still be processed there. Read Cloudflare's privacy policy.
Short answer
Veil Translate is a private document translator for confidential files, not a general replacement for every translation tool. For teams looking for a DeepL alternative, it adds local masking before either browser-direct BYOK or fixed managed translation, then restores confirmed sensitive values on your device.
What's different
The original file, mapping table, passwords and derived keys stay in the browser. A BYOK API key stays only in the current tab's memory and is sent only to your chosen provider, never to Veil Translate or disk. Parsing, detection, masking, restoration and file rebuilding happen locally; only masked body text leaves the browser.
In BYOK mode, your browser sends masked text and your key directly to the OpenAI-compatible endpoint you choose. In managed mode, the official client sends masked text through Veil Translate's fixed proxy to Cloudflare Workers AI; you cannot choose an upstream URL, model or prompt.
An honest boundary
Veil Translate is not end-to-end encrypted translation. It protects the sensitive entities it detects and you confirm; undetected sensitive data and the remaining de-identified text may still leave as plaintext. BYOK sends them directly to your chosen provider, while managed mode relays them through Veil Translate to Cloudflare Workers AI.
When to use which
For casual, non-sensitive text, a mainstream translator is fine. For contracts, HR files, financials or anything with personal data — especially in DOCX/XLSX/PPTX where layout matters — Veil Translate keeps the sensitive parts on your device and preserves formatting.
Frequently asked questions
How is this more private than Google Translate?
The original file and mapping table stay in your browser, and confirmed sensitive entities are replaced with placeholders before translation. BYOK sends masked text directly to your provider; managed mode relays masked text through Veil Translate to Cloudflare Workers AI. The remaining de-identified body text still leaves as plaintext.
Does Veil Translate use DeepL?
No. This is a comparison of privacy workflows, not a DeepL integration. BYOK sends masked text to the OpenAI-compatible endpoint you choose; managed translation uses a fixed Cloudflare Workers AI model.
Does it cost anything?
The managed mode includes a capped free daily quota. BYOK use of the app is free, but your chosen model provider may charge for translation calls made with your key.
Which engines can I use?
BYOK supports OpenAI-compatible endpoints such as OpenAI, DeepSeek, Kimi, OpenRouter, or a custom base URL that allows browser requests. Managed translation uses a fixed Cloudflare Workers AI model and does not use a user-supplied URL, model, prompt or key.
Is Veil Translate a private translation app or confidential translation software?
It is a browser-based private document translation app, not an offline or on-device translation model. The original file and confirmed sensitive values stay local, but masked body text is still processed by your BYOK provider or, in managed mode, Cloudflare Workers AI.
