Four things you actually need before you hit publish. The character counter and the timing guide are instant and unlimited. The two AI tools ask for your email and run twice an hour.
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.
