ByteProof proofreads the text you select. In Word, edits arrive as tracked changes. In any other app, your selection is replaced with the polished version.
Tracked changes in Word
Polishes text in any app
Cmd+Shift+' to proofread
Local AI included, or bring your own model
Three steps, one hotkey. Each clip below is the real app, about three seconds long.
Cmd+Shift+' on a Mac, Ctrl+Shift+' on Windows. ByteProof reads the words around your selection too.
Each suggestion shows the original, the replacement, and a short reason. Apply the ones you want, or dismiss the rest.
Apply every change in one click. If you change your mind, Undo puts the original text back.
ByteProof detects what you are working in and adapts. The hotkey is the same either way.
For papers, theses and reports where every edit has to be visible.
Email, browsers, editors, chat. Select, press the hotkey, and read the suggestion.
Four kinds of writing. ByteProof keeps your meaning and cuts what gets in the way.
For a manuscript heading to a top-tier journal: wordy phrasing trimmed, argument untouched.
"We utilise a range of methods in order to examine the relationship due to the fact that the data is limited."
"We use a range of methods to examine the relationship because the data is limited."
Three phrases cut. The finding is unchanged.
A routine team email: filler removed, tone kept friendly.
"Hi team, the meeting has been rescheduled to Thursday at 10am instead of Wednesday. Sorry for any inconvenience. The agenda has been updated and is in the shared folder if you want to look before the meeting."
"Hi team, the meeting has moved to Thursday at 10 am instead of Wednesday. Apologies for the inconvenience. The agenda is updated and in the shared folder, so you can review it beforehand."
Shorter, still friendly, ready to send.
A chapter draft: your voice and your argument stay, repetition goes.
"To examine the relationship between corporate governance and firm value, this chapter draws on agency theory. The analysis focuses on the role of independent directors and how their presence affects monitoring quality."
"To examine the relationship between corporate governance and firm value, this chapter draws on agency theory. It focuses on independent directors and how their presence affects monitoring quality."
Meaning and voice kept; the repeated clause removed.
A professional letter: formal, and clear about what you want.
"Your account shows an outstanding balance of $450, overdue since 1 March. Please pay as soon as you can. If you have any questions, contact our accounts team."
"Your account has an outstanding balance of $450, overdue since 1 March. Please arrange payment at your earliest convenience. If you have any questions, please contact our accounts team."
Formal, direct, no filler.
Small mistakes matter in academic and professional work. ByteProof is made for that.
Every edit lands as a tracked change. Accept or reject each one.
Short notes explain why a change was made, instead of quietly rewriting your work.
References, equations and tables are kept as they are.
Tone, references and meaning stay consistent with the rest of the document.
