Free AI LinkedIn Message Generator

FirstLine is a free Chrome extension that generates personalized LinkedIn messages — not from a template, but from the actual profile you're looking at. It finds a real reason to reach out first, then writes the message around it.

How it works

  1. Open any LinkedIn profile. FirstLine lives in a side panel inside LinkedIn — no tab switching, no copy-pasting.
  2. It reads the profile and finds signals. Role changes, career patterns, stated priorities — concrete facts, not "works in tech."
  3. You pick the signals and the goal. Book a demo, pitch a role, or just start a conversation. You stay in control of the angle.
  4. It writes two drafts under 50 words each. An initial message and a follow-up, ready to edit and send yourself.

A real output, generated from a profile's role change and growth signals:

Generator vs. templates vs. ChatGPT

Template tools scale the wrong thing: the same message to everyone. Chat tools can write well but start from a blank page every time — and the research is still on you. A context-first generator does the research step, which is the part that actually earns replies. More on that in our outreach framework.

What it deliberately doesn't do

Frequently asked questions

Is it really free?

Yes. Install the extension and start generating — no card, no trial countdown. A Pro plan with advanced features is on the roadmap, but the core product is free today.

How is this different from ChatGPT?

ChatGPT writes from whatever you paste into a blank prompt. FirstLine reads the profile automatically, extracts signals, lets you choose which ones to use, and writes grounded messages inside LinkedIn's side panel.

Does it send messages automatically?

No — drafts only. You stay in control of every send.

Who is it for?

Sales reps and SDRs, recruiters sourcing passive candidates, and founders doing manual outbound. Pick your role and the generator adapts its insights, tone, and goals. Want to see the output style first? Browse 15 example messages.
