Free AI LinkedIn Post Generator
Generate LinkedIn posts that earn 10+ word comments instead of 'great post!' emoji replies. Tuned for the 2026 LinkedIn algorithm: comment-depth as the dwell-time proxy, the 90-day cadence reset, the 3-5 PascalCase hashtag sweet spot. No signup, no card.

Why this generator works for LinkedIn
What we actually enforce for LinkedIn
Not the numbers in the platform's docs. These are the ones our own publisher validates every post against before it ships.
- Character cap
- 3,000
- Hashtags allowed
- 5
- Images per post
- 20
- Media required
- no
The generator aims at 1200 to 1500 characters. That is our engine's default for LinkedIn, not a measured optimum for your account, and we are not going to present it as one.
Go past the cap and we trim at the nearest sentence boundary rather than rejecting the post or cutting mid-word. Truncates at ~140 characters in feed. Image recommendation: 1200x627. Multi-image carousels: 2-20 images.
Architected to earn substantive comments
LinkedIn now ranks comments-with-substance (10+ words) much higher than emoji or single-word replies. A post with 30 substantive comments out-distributes one with 200 "great post!" replies. Our generator architects every post around a question that requires the reader to share their own experience to answer, exactly what the algorithm rewards in 2026.
Hashtags formatted as #PascalCase
LinkedIn favours #PascalCase tags (#SocialMediaMarketing, not #socialmediamarketing). Our generator formats hashtags correctly per LinkedIn convention and stays inside the 3-5 sweet spot, not the 10+ tag stuffing that LinkedIn explicitly demotes.
150 to 300 word body sweet spot
LinkedIn lets you write 3,000 chars, but the real engagement sweet spot is 150-300 words. Long enough for a real take, short enough to not hide the engagement question past the "see more" fold. Our generator hits this band consistently.
Cadence-aware (works inside the 90-day window)
LinkedIn re-evaluates an account's relevance score on a roughly 90-day rolling window. Inconsistent cadence drops the score; even low-frequency steady (2 posts/week) beats inconsistent 5/week. The full Content Drifter app schedules around this; the free generator gives you the post.

Frequently asked questions
Is this LinkedIn post generator really free?
Yes: no signup, no credit card, no rate limit on this landing. The full Content Drifter app (scheduling + auto-publishing + brand-voice training + closed-loop analytics across all 9 networks: LinkedIn, IG, X, Facebook, Threads, YouTube, Pinterest, Bluesky, TikTok) also has a free forever plan. LinkedIn, like every network, is on the free plan; hands-off auto-publishing of a scheduled post starts on Starter ($19/mo).
How is this different from ChatGPT for LinkedIn posts?
ChatGPT writes posts but doesn't know LinkedIn's 2026 algorithm shifts (comment-depth weighting, 90-day cadence reset, PascalCase hashtag convention). Our generator is tuned every week to the latest platform signals and architects every post around a real engagement question, not a "thoughts?" close. ChatGPT also writes in a "polished essay" cadence that LinkedIn's AI-content-disclosure detection now flags.
Will my posts sound like ChatGPT wrote them?
Not if the cadence rules do their job, which is the part you can judge for yourself in one generation. On this free landing, the captions follow our anti-AI-cadence prompt rules (no em-dashes, varied sentence length, contractions, fragments). For full Voice-Match (the AI scores every generated post against your actual writing style and rewrites it on drift), sign up free and paste 3-5 of your past LinkedIn posts.
Does this generate LinkedIn carousels too?
Not from this free landing: carousel generation needs the design layer. Sign up free and the carousel maker builds 5-slide decks with your Brand Kit applied automatically (your logo, your colors, your fonts), so you stop opening Canva for the weekly LinkedIn carousel.
How long should a LinkedIn post be in 2026?
The 2026 sweet spot is 150-300 words. LinkedIn lets you write 3,000 chars but anything past 300 hides your engagement question below the "see more" fold and loses the dwell-time signal. Our generator stays inside the 150-300 band by default, with longer 500-word "essay-post" mode available when the topic genuinely needs it.
