Why per-platform limits matter

The same caption that fits an Instagram post gets truncated on X and cut off on Bluesky. Oxhype solves this automatically — it writes a native-length caption per platform from one upload, so you never hand-trim again.

Check any caption in three steps.

  1. Paste your caption

    Drop your draft into the counter. Nothing is uploaded — it runs entirely in your browser.

  2. Scan every platform

    See your live character count against X, Bluesky, Threads, Instagram, TikTok, LinkedIn, and YouTube limits at once.

  3. Trim or let Oxhype handle it

    Cut where you're over, or let Oxhype write a native-length caption per platform from one upload.

Stop counting characters by hand.

This tool tells you where you're over. With AI turned on, Oxhype drafts a correctly sized caption for each platform.

  • Per-platform captions

    Oxhype drafts a native-length caption for every network from a single upload — no manual trimming.

  • Always in-limit

    Captions are generated to fit each platform's format, so posts never get truncated unexpectedly.

  • One upload, many posts

    Write once; Oxhype adapts length, tone, and hashtags per platform and publishes for you.

Character counter questions

Is this character counter free?

Yes. It's completely free, needs no sign-up, and runs entirely in your browser — your text never leaves your device.

What platform limits does it check?

It checks X/Twitter (280), Bluesky (300), Threads (500), Instagram and TikTok captions (2,200), LinkedIn posts (3,000), and YouTube descriptions (5,000). Platforms occasionally change these, so confirm against the network's current docs.

Do emojis count as one character?

The counter counts by Unicode code point, so most emoji count as one. Note that some platforms count certain emoji or links differently in their own editors.

Can Oxhype write captions that fit?

Yes, if you turn on AI. Oxhype's AI assistant drafts a platform-native caption for each network from your text, sized to fit that platform, so you don't hand-trim.
