Letter Moth vs Gmail Help Me Write: Which Should You Use?
Gmail's Help me write is Google's built-in AI drafting feature for email, part of its Gemini features. If you only write in Gmail and your account has it, it may be all you need. Letter Moth drafts from the page you have open, across LinkedIn, email and job forms, in a voice based on a profile you write once.
Availability of Google's feature depends on your account and plan, and it changes over time, so check whether it appears in your own Gmail.
We build Letter Moth, so we are not neutral. We will cover where the built-in feature is a natural choice and where a separate extension adds value.
| Question | Letter Moth | Gmail Help me write |
|---|---|---|
| What it is | Chrome extension for outreach drafts | Google's AI drafting inside Gmail |
| Where it works | LinkedIn, email boxes, job forms | Inside Gmail |
| Availability | Chrome, Edge, Brave, Opera; sign in with Google | Varies by account and plan, check yours |
| Context from other sites | Yes, the page text you approve | Not its purpose (check) |
| Character-limit fit | Reads the box limit and trims | Check whether it does |
| Sends messages | Never | You send from Gmail |
| Cost | Free plan, Pro on pricing page | Check Google's current plans |
What is Gmail Help me write?
It is Google's AI drafting help inside Gmail's compose window. You describe what you want and it produces a draft, which you can refine. It is part of Google's Gemini features, and whether you can use it varies by account type and plan. Check Google's help pages and your own compose window.
Because it is inside Gmail, it requires no extra install, and it is aware of the email context in front of it.
Letter Moth is a different kind of tool: a Chrome extension (also Edge, Brave and Opera, not Firefox or Safari) that works across sites rather than only inside one.
When is Help me write the better choice?
If your outreach lives entirely in Gmail, you have access to the feature, and you are comfortable with Google's data handling, it is a natural option. There is nothing to install, and it is integrated with the product you already use.
It may also be better for replying within long email threads, since it sits within the mail interface. Check what context it uses before relying on it.

Where does Letter Moth add value for cold email?
Cold email often starts from something outside Gmail, such as a LinkedIn profile, a company page or a job post. Letter Moth reads the page text you approve and drafts from it, then you take that to the email box. The same tool can also write the LinkedIn note, referral request and follow-up from the same profile of you.
You write a profile once, so your name and role go into every draft. You choose a tone: natural, professional, casual, warm or concise.
See the cold email writer page for details, and our guide on writing a cold email that gets replies.
How do they differ on privacy and control?
For Gmail's feature, review Google's privacy information and your account's settings.
For Letter Moth, page text is read only when you click the toolbar button or use the right-click menu in a text box. You see the context first and can untick parts. It never reads password or payment fields. The text goes to our server and the AI provider only to write the draft, is not sold, and is not kept after the draft is made.
Letter Moth never sends anything and never clicks for you.
How do you write a cold email that sounds like you?
Start with who the email is for and why them. A short subject, one specific line of context, one clear ask. Drafting tools, built in or otherwise, work best when you give them a real reason for writing rather than a vague goal.
Then edit hard. Cut anything that sounds like a brochure. If a sentence could be sent to a hundred people unchanged, replace it with one that could only be sent to this person.
- Keep it under about 120 words where you can.
- Put the ask in the last line, in plain words.
- Avoid claims you cannot back up.
- Send a single polite follow-up if you hear nothing.
How do they compare in a table?
Google's features change and differ by account, so verify what your own Gmail offers.
