Free social media tools.
No account, no email.
Four things you actually need before you hit publish. Use them as often as you like — the AI-powered ones are capped per hour so they stay free for everyone.
Character Counter & Preview
Paste a post and see instantly whether it fits X, LinkedIn, Instagram, Bluesky, Threads, Pinterest and Facebook — with the real cut-off points marked.
Open the counter →Caption Generator
Describe your post and get three publish-ready captions in three different angles — direct, story-led and question-led — written for the platform you pick.
Write captions →Hashtag Generator
Twenty hashtags ordered from broad reach to niche buying intent, sized for the platform — not twenty copies of the same giant tag nobody converts from.
Generate hashtags →Best Time to Post
Posting windows by platform, converted to your own time zone, with the honest caveat about what these averages can and can't tell you.
See the windows →These four are the manual version
AIBrandBlast does the whole loop instead: it writes the post, generates the image or video, publishes it to your platforms and your own website, then schedules the rest. A week of marketing in about 20 minutes.
