Build social media bios with character limits for each platform, emoji suggestions, and link formatting.
You fill in who you are and what you do, and the tool drafts a bio for each major platform, counting every character - spaces, emojis, and your link included - against that platform's own limit. Over-limit drafts get flagged or trimmed before you paste them, and emoji suggestions plus link formatting are part of the same pass. The thing that catches people out: the limits sit far apart. A bio that fits Instagram's 150 and X's 160 characters is already too long for TikTok's 80 or Facebook's 101, and pasting an over-limit draft just makes the platform truncate it mid-sentence, no warning.
A concrete input and expected output from the current implementation.
Input
Marketing consultant for small businesses. I turn spreadsheets into strategy, and strategy into sales. Book a free audit: linktr.ee/janedoe
Expected output
Count: 139 characters, link included. Fits: Instagram (150 limit, 11 spare), X (160 limit, 21 spare). Over limit: TikTok (80), Facebook (101) - flagged for trimming.
The draft counts to 139 characters - 42 for the first sentence, 60 for the second, 37 for the third including the 17-character link - so it clears Instagram (150) and X (160) but overruns TikTok (80) and Facebook (101). Those two get flagged for trimming instead of truncating on paste.
Every platform enforces a different ceiling: 160 for X, 150 for Instagram, 80 for TikTok, 101 for Facebook's About field, 2,600 for LinkedIn. The tool counts the draft as written - spaces, punctuation, emojis, and the URL all included - compares it with each ceiling, and reports per network whether the draft fits, by how much, or how many characters over it runs.
Suggested emojis are inserted into the draft and counted like any other character, so a bio that fits plain can tip over once decorated. The link is formatted for clean display in a profile, and it consumes budget too: a short address such as linktr.ee/janedoe alone costs 17 characters before any text is counted.
Usually one of three things: the platform changed its limit after the tool's data was last updated, an emoji composed of multiple code points counts as two characters on the platform's counter, or you edited the draft after the count ran. Paste the exact final text into the platform's own editor and let its counter decide.
Yes. The URL occupies part of the budget on every platform - a linktr.ee address alone runs 15-20 characters - and the tool counts it like any other text. If the count is tight, shorten the address first, or move the link to a pinned post or a dedicated link-in-bio field where the platform offers one.
