A calmer place to get your writing ready.
Glyphometer is a free, static browser tool for people who write captions, post updates, prepare titles, and need to keep track of changing platform limits.
What makes it useful?
A single draft can have a different counted length on X, Bluesky, TikTok, and YouTube. Glyphometer offers quick visual comparisons and twelve practical text operations—from fixing duplicate spaces to decoding HTML entities—in one accessible workspace.
Built to load quickly
The site uses plain HTML, CSS, and JavaScript with no external JavaScript framework, web font download, sign-up service, or backend. Text transformations work locally on modern browsers. Optional ad integration is disabled until configured by the website owner.
Limits and transparency
Glyphometer's counters are drafting aids rather than official validation tools. Platforms can update limits or use account-specific requirements. Automatically corrected homophones and slang should be reviewed before use; they cannot understand every possible context.
