Letter Moth vs SmartWriter: Personalised Outreach Compared
SmartWriter is generally described as an AI tool for personalised outreach in sales prospecting. Letter Moth drafts one message at a time from the page you have open, and never sends or automates anything. If you run prospecting at volume, a sales-focused tool may suit you. If you write individual messages and want control, Letter Moth is simpler.
The deciding question is scale and style. Do you want to personalise many messages through a sales workflow, or write each one yourself with a drafting assist?
We make Letter Moth, so we are not neutral. We keep SmartWriter's description general because products change, and we suggest checking its site for what it does now.

What is the difference between Letter Moth and SmartWriter?
SmartWriter is generally positioned for sales and prospecting, helping personalise outreach for lists of leads. Check its site for specifics, since features and workflows change.
Letter Moth is deliberately not a prospecting platform. It is a Chrome extension (also Edge, Brave, Opera, not Firefox or Safari). You click the toolbar button, it reads the page text you approve, and it drafts a LinkedIn note, cold email, referral request, follow-up, reply or job answer in your voice.
One is oriented around prospecting workflows. The other is oriented around a single message and your editing.
When is a sales prospecting tool the better choice?
If your job is outbound sales at volume, with lists of leads, repeated personalisation and a sales stack, a prospecting-oriented tool is a better match. Letter Moth has no CRM, no sequences, no analytics, no email finding and no bulk sending.
We designed it that way on purpose, partly because bulk automation can get accounts flagged and make outreach feel impersonal. If you want to understand the difference in approach, read LinkedIn automation tools vs AI drafting assistants.
For a broader list, see the SmartWriter alternatives guide.
When does Letter Moth fit better?
When you want to stay the sender. You open a profile, check what it found, untick anything you do not want used, pick a tone and generate. The draft lands in the box, trimmed to the character limit. You edit and press send.
It suits job seekers asking for referrals, recruiters writing to a few candidates, founders reaching out to a handful of people, and anyone who would rather send 10 considered messages than 500 templated ones. Try the LinkedIn message generator page.
It also covers job-application answers, which prospecting tools generally do not.
How do safety and privacy compare?
Letter Moth reads page text only when you click the toolbar button or use the right-click menu in a text box. It never reads password or payment fields. Page text goes to our server and the AI provider only to write that draft, is not sold, and is not kept after the draft is made. It never clicks or sends for you.
For SmartWriter, review its data practices and how it gathers information on its own site.

How do you keep outreach personal at any volume?
Whatever tool you use, the messages that tend to land are short, specific and clearly written by a person who read the profile. A drafting assist can speed up the reading and the first sentence, but it cannot supply genuine interest.
A practical rule: if you would be embarrassed to see the message screenshotted, send fewer messages and write them better. We do not promise reply rates, and you should be sceptical of any tool that does.
- Reference one real detail from the recipient's work.
- State why you are writing in the first two sentences.
- Make the ask small and easy to answer.
- Follow up once, politely, with something new.
How do they compare in a table?
SmartWriter's column is general on purpose. Competitor products change, so verify details on its site.
