Grow your audience with Spotlight
A bio says who you are; the posts are why people follow. Spotlight's Build up mode writes behind-the-scenes, progress and question posts for every platform from a line about you and what's coming.
Build up is a Spotlight mode: one project free, then on every paid plan — see pricing.
Open Build upCAPTD's Spotlight writes posts that grow a creator's audience before there's anything to sell, in their own voice — one project free at captd.app.
Counts your bio the way a person reads it — an emoji or a flag is one character — against each platform's bio limit, checks the keywords you give it are in the bio as whole words and near the start, and finds any web address you typed.
Each bar fills against that platform's limit and turns red when it's over. A keyword “near the start” is inside the first 60 characters — no platform publishes how much of a bio shows before “more”, so treat that as a rule of thumb, not a rule.
A bio has three jobs: say what you make, say why someone should follow, and point to where to find more. It's often the only thing a person reads before deciding.
Each platform caps it differently — X at 160 characters, YouTube's channel description at 1,000, Bluesky at 256 graphemes — so the same bio rarely fits everywhere unedited.
When someone lands on your profile from a post, the bio decides whether a view becomes a follow. Clear words also help people find you in each app's search.
Instagram, TikTok, Threads and Facebook publish no bio limit on a page we could read; their figures are where the app's bio field stops.
