Proofbird
Closed beta · Windows

Proofreading inside the apps you already write in.

Proofbird reads your text as you work in Trados Studio, Trados Cloud, Word, Outlook and your browser, and marks spelling, grammar, style and terminology right on the page. The grammar and spelling models run on your own machine.

Proofread by a bird that never looks away.

Your text stays on your machine

Spelling and grammar run on models installed on your PC. Nothing is uploaded, nothing is logged by us, and it works offline.

  • On-device models for English, German, French, Spanish and Italian
  • Your termbases and dictionaries stay local too
  • Text leaves your machine only through an AI engine you connect yourself

Bring the AI you already pay for

For rewrites and translation, connect a subscription you already have. No developer account, no per-word charges.

  • Claude Code · ChatGPT Codex · Z.AI · Ollama Cloud
  • Or Ollama and LM Studio on your own PC
  • You choose which engine does what, and when it runs

Optional. Proofreading works with no engine added.

Private by construction, not by promise.

Proofbird was built for translators, who sign confidentiality agreements for a living. The proofreading you get out of the box never sends a word anywhere. When you do connect an AI subscription, it is your account, your plan and your choice, one engine at a time.
