Letter Moth vs LinkedIn AI Writing Assistant: Which Helps?

· 3 min read · By the Letter Moth team

LinkedIn has been adding its own built-in AI help for writing, and what you see depends on your account and plan. Letter Moth is a separate Chrome extension that drafts from the page you have open, on LinkedIn and elsewhere. If the built-in option covers what you need, use it. If you want one tool across LinkedIn, email and job forms, Letter Moth may help.

We cannot describe LinkedIn's current AI features precisely, since they vary by account, region and over time. Check what appears in your own account before comparing.

We make Letter Moth, so this is our perspective. We will focus on the practical differences in where each tool works and how much control you keep.

What is the LinkedIn AI writing assistant?

It refers generally to AI-powered writing help that LinkedIn offers inside its own product, such as help drafting messages or posts. Availability can depend on your account type and plan, and the details change. Look for it in your own message box, and check LinkedIn's help pages for the current description.

Because it is built into LinkedIn, it lives where LinkedIn lives. That is both its convenience and its boundary.

Letter Moth is a separate Chrome extension (also Edge, Brave and Opera, not Firefox or Safari). It works on LinkedIn pages, email compose boxes and job forms.

When is the built-in option enough?

If you only write on LinkedIn, and the built-in assistant is available on your account and does what you want, you may not need anything else. It requires no install and no extra sign-in. Try it first, and judge the drafts against your standards.

It is worth checking whether it uses the recipient's profile, whether it respects the connection note limit, and whether you can choose a tone. Those are the questions that matter, and the answers may differ by account.

Our connection request guide is useful whichever tool you use.

When does Letter Moth add something?

When your outreach is not only on LinkedIn. The same profile of yours drives a connection note, a cold email in Gmail, a referral request, a follow-up and a job-application answer. You write your profile once, and your name and role go into every draft.

It reads the page text only when you click the toolbar button or use the right-click menu in a text box, shows you the context, and lets you untick parts. It also reads the box's character limit and trims the draft to fit.

For job seekers, the job application answer generator page covers the non-LinkedIn side.

Which keeps you more in control?

Both should leave you as the sender. Letter Moth never sends anything, never clicks for you, and does no scraping or automation. It also 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.

For LinkedIn's own feature, review LinkedIn's privacy information and settings for AI features in your account.

How can you test both quickly?

Open the same profile and draft a connection note with each option. Look at three things: whether the draft uses a real detail from the profile, whether it fits the note's character cap without clumsy cuts, and whether it sounds like you.

If one tool consistently needs less editing, that is your answer for now. Tools change, so repeat the test occasionally.

  • Does the draft mention something specific about the person?
  • Is it within the limit without awkward trimming?
  • Can you choose a tone that matches your style?
  • Does it leave sending entirely to you?

How do they compare side by side?

The LinkedIn column is cautious because features differ by account and change over time. Verify what you have in your own account.

What does Letter Moth cost and not do?

LinkedIn's AI features may be tied to a paid plan or may not be available to you, so check your account. Letter Moth has a free plan with 10 drafts a day and 3 saved prompts, no card. Pro is unlimited, prepaid at INR 299 for 30 days or INR 2,499 for a year, with no auto-renewal and a 7-day refund on the first Pro purchase. See pricing.

What Letter Moth does not do: it has no CRM, sequences, analytics or email finding, and it does not send. It also does not replace LinkedIn. If you want to try a cross-site drafter, add Letter Moth to Chrome.
