How It Works

1

Share Your Email Draft

Share any email to your boss, a client, a colleague, or anyone.

Can you check the tone of this email I'm about to send to my manager? Hi David, I still haven't received the updated figures you promised last Tuesday. This is holding up the entire report and the deadline is tomorrow. Please send them today.

Is this the first time you're chasing him, or has he ignored you before?
Twice already.

Do you need to keep him on your side after this, or do you just need the numbers?

Get a Detailed Tone Breakdown

The tool identifies exactly which words or phrases create the wrong impression, whether that's sounding demanding, passive-aggressive, cold, or overly casual. You'll see why each flag matters.

The email opens on the attack. It's urgent, but the kind of urgent that makes people feel cornered. "I still haven't received" and "you promised" frame David as someone who already failed — before he's even finished the first line. People who feel blamed don't rush to help, they rush to defend themselves. "This is holding up the entire report" is factually true, but saying it out loud assigns fault rather than creating urgency.

Receive a Personalized Rewritten Version

Get a polished rewrite that fits the situation. Same meaning, only the parts that could backfire get fixed.

Here's a rewritten version that keeps your urgency while protecting the working relationship: Hi David, I wanted to follow up on the figures we discussed for Tuesday — I haven't received them yet, and our report deadline is tomorrow. Could you send them over today? Happy to jump on a quick call if anything came up on your end. Thanks, [Your Name] Blame replaced with shared context, demands replaced with requests. Same urgency — without putting David on the defensive before he's even replied.

What You'll Improve

Spotting Unintentional Tone

Learn to recognize phrases that read as passive-aggressive, cold, or demanding, even when you did not mean them that way.

Rewriting for Clarity and Warmth

Practice replacing harsh or vague phrasing with language that gets your point across while keeping the relationship intact.

Calibrating Tone to the Relationship

Develop the ability to adjust your email register, more formal with a client, more direct with a peer, without sounding stiff or cold in either case.

Writing Follow-Ups That Get Responses

Stop accidentally guilt-tripping or pressuring people with follow-up emails. Learn the patterns that prompt replies instead of resentment.

Delivering Feedback Without Creating Conflict

Learn to write honest, direct feedback that people can actually hear without triggering defensiveness or damaging trust.

Setting Limits Without Sounding Dismissive

Practice writing firm boundary-setting or decline emails that are professional and respectful, not cold or curt.

Voices from Our Users

“

I sent a follow-up to a client that I thought was professional. My manager saw it and said it sounded aggressive. Now I run every client-facing email through this tool first. Hasn't happened again.

Priya N., Project Manager

“

My close rate actually improved after I started checking my follow-up emails here. Turns out I was coming across as impatient and clients were going cold. Fixing the tone fixed the conversion.

HR emails are a minefield. One word wrong in a performance message and you have a grievance on your hands. This tool has saved me from at least three situations that could have escalated badly.

Aisha Okafor, HR Business Partner

“

I'm technical, not a writer. I used to just send what I drafted and hope for the best. Now I paste it in, get the rewrite, and actually understand why my original version sounded blunt. It's made me better at writing, not just dependent on the tool.

Marcus.L, Engineering Lead

Tech Startup

“

Dealing with frustrated customers over email is genuinely hard. This tool helped me find the line between empathetic and firm — I stopped sounding either defensive or like I was caving. My CSAT scores went up noticeably.

Sofia Bergmann, Customer Success Manager

Enterprise Software

“

When you work for yourself, every email to a client either builds the relationship or chips away at it. I check all my difficult emails here before sending. It's like having a senior colleague review my drafts — except available at midnight.
