Casual to professional
yeah that timeline wont work, its way too tight. we need two more weeks or quality is gonna suffer
Unfortunately, that timeline is tighter than we can deliver against responsibly. Could we extend the schedule by two weeks? That would give the team enough time to complete the work without compromising quality.
Why the rewrite is better: It removes slang and blame, states the constraint clearly, and turns the complaint into a specific, constructive request.
Plans from $9/mo, or Lifetime from $69 with your own API key.
More before and after examples
Each rewrite preserves the original intent while making the task clearer and easier to act on.
Formal to warm and conversational
Please be advised that your attendance at the aforementioned onboarding session is requested at your earliest convenience.
We’d love to have you join the onboarding session. When you have a moment, please choose the time that works best for you.
Why the rewrite is better: The rewrite replaces bureaucratic phrasing with a warm invitation and a simple action while keeping the request respectful.
Blunt feedback to tactful and direct
this draft is confusing and way too long. redo it before the client sees it
The main recommendation is difficult to find in the current draft, and several sections repeat the same point. Please lead with the recommendation, remove the repeated background, and send a shorter revision before we share it with the client.
Why the rewrite is better: It replaces a personal judgment with observable problems, gives concrete revision steps, and keeps the deadline and quality bar clear.
One desktop install works everywhere, with writing profiles such as Professional, Email, Reply and Concise plus a per-app default profile. The Chrome extension is an addition for in-place rewriting and per-website profiles without Accessibility permission. Optional IDE extensions add profile and output controls in editor AI chat panels, while the desktop app already covers them and terminals.
