What this tool is for
You want a starting draft without creating another account. Paste a topic you actually know something about, generate once, then rewrite the top third and the last line by hand. That is the honest use of a free generator.
It is not a replacement for a content system. There is no voice profile, no avoid-list, and no reviewer agent. If every draft you get from generic AI still needs a full rewrite, the bottleneck is constraints, not another prompt box.
How to get a usable draft
Be specific in the topic field. "Leadership" produces soft mush. "I waited three weeks to fire a vendor and it cost the April launch" gives the model something to hang a story on. Add a tone hint if you want shorter lines or a drier voice.
After it generates, run a short human pass: cut the throat-clearing opener, add one detail only you would know, and delete any sentence that could sit under a competitor's name. Use the character counter if you care about the see more cutoff around 1,300 characters.
Format bold or bullets with the text formatter before you paste into LinkedIn. Unicode styling is optional. Clear writing matters more.
Limits and why they exist
Free AI tools without a daily cap get scraped into oblivion. Three successful generations per IP per day keeps cost predictable and keeps the page available for people who actually need a draft. The bot check exists for the same reason.
When you need more volume, or drafts that start from your real posts, that is what the linkedinpost.ai free plan is for: voice profile, Council review, and approval before anything schedules. This page is the ungated on-ramp, not the whole product.
When to switch to the full product
Switch when you are posting two or three times a week and tired of re-explaining your voice every Monday. Switch when generic drafts keep dying in your notes app. Switch when you want a calendar and a clear approve step instead of Slack threads.
Stay on this free tool when you only need an occasional jumpstart and you already write well. Plenty of people do both: generate a rough angle here, finish the system inside the product.
