Find prospects
The tools help with the post. Extrovert helps with the people.
Extrovert is a LinkedIn outreach assistant for founders and sales teams. It finds prospects, suggests who to comment on or DM today, and prepares drafts in your voice. You decide what goes out.
Finds prospects
Describe your ideal customer to find people who fit, or let Intent Signals find them by their LinkedIn activity. You choose who to add.
Prioritizes actions
Two short lists for today, comments and DMs, every item with a reason.
Prepares drafts
Drafts use the actual post or conversation and your writing style. Extrovert checks for AI-sounding phrases before you review.
Illustration: two stacks, prospects' posts and conversations, sorted into today's priorities. Posts rise with reasons such as "One more comment, then outreach", "On your topic", "Overdue for a comment" and "Where your buyers read"; an off-topic post drops out. Conversations rise with "New role, follow up early", "Two weeks with no reply" and "Ready for a first DM"; a slow nurture waits. The result is two short lists, comments for today and DMs for today; what sinks below the line is marked "Not today".

Frequently asked questions
Are these LinkedIn tools free?
Yes. Every tool on this page is free to use, with no account, trial or card.
Do I need to log in to LinkedIn to use them?
No. You paste text, a post link or a profile link, and the tool works from that. None of them asks for your LinkedIn login or connects to your account.
Which tool should I use before I publish a post?
Start with the LinkedIn Post Formatter. It adds bold, italics, lists and spacing, and its feed preview shows where the post is cut at “…more”. If you only need the length, the Character Counter checks your text against each LinkedIn limit.
