5 AI Social Media Post Generators With Scheduling (2026), Verified
You generate captions, threads and posts in your own voice and schedule them from one tool. Five verified tools compared on price, free plan, networks and monthly caps.
AI post generators draft captions and threads from an idea, then queue them for publishing. The five tools here come from our verified catalogue: Ocoya, Supergrow, Tweet Hunter, TweetAI and OpenTweet. Ocoya covers several networks with a brand kit. Supergrow is built for LinkedIn. The other three focus on X. Only TweetAI has a free plan, and its free access is limited per day. The rest offer 7-day trials, some of which require a card. Credits, auto-DM caps and per-network limits differ, so read the limit column. Always review AI-written posts before publishing and follow each network's rules on automation.
