What's AI here, and what isn't

This is an AI agent: it uses an AI model to read, sort, score or draft. It runs in your own accounts. Anything it would send outside your business waits for your approval unless you choose otherwise, and it never needs your passwords. Our AI disclosure.

How do I get LinkedIn Post Check?

It isn't on sale yet. It's planned at Free on Gumroad, with a 14-day refund. Press "Get notified" to follow us on Gumroad and hear when it launches.

Does it post to LinkedIn?

No. It never logs in or posts. You copy the post and publish it yourself.

Will this get me more reach?

It cannot promise that. It checks the habits that make posts harder to read; what you say still matters most.

Why flag Unicode bold?

Those letters are maths symbols. Screen readers may read them letter by letter or skip them, and LinkedIn search does not match them.

Is the free version limited?

One post per run. No account and no cap.
