Smart Sentence Splitting

Unlike dumb splitters that chop words in half, Tweet Splitter looks for sentence endings (.?!) first. If a sentence is too long, it finds the nearest safe space to break, ensuring your thread reads naturally.

5 Platforms + Custom

X (280), Bluesky (300), Threads (500), Mastodon (500), LinkedIn (3K) — or enter any custom character limit. Counter reservation ensures numbering never pushes a chunk over the limit.

Privacy by Design

100% client-side. Your text never leaves your browser. No OAuth, no account, no API calls. Export your thread as .txt or .md. Keyboard shortcuts (when focus is outside the text box): Ctrl/Cmd+Shift+Y copy all, Ctrl/Cmd+Shift+E export .txt.

Frequently Asked Questions

How do I split text into a Twitter thread?

Paste your long text into the box above, make sure the platform is set to Twitter/X, and click Split. Tweet Splitter automatically breaks your text at sentence boundaries into numbered tweets, each under 280 characters. Click Copy on each tweet and post them in sequence on X.

What is the character limit for a tweet in 2026?

The standard character limit on X (formerly Twitter) is 280 characters for free accounts. X Premium subscribers get up to 25,000 characters per post. Tweet Splitter defaults to 280 characters and adjusts automatically.

How many tweets can a thread have?

There is no official limit on thread length. In practice, threads of 5–25 tweets perform best for engagement. Tweet Splitter will split into as many tweets as your content requires.

Is Tweet Splitter free? Do I need to create an account?

Completely free. No account, no login, no subscription. Tweet Splitter runs entirely in your browser — your text is never uploaded to any server.

Does Tweet Splitter store or read my text?

No. Tweet Splitter is fully client-side. Everything runs in your browser tab. Your text never leaves your device. This is a core id8 principle — privacy by default.

Can I use Tweet Splitter for Bluesky or Mastodon?

Yes. Select Bluesky (300-character limit) or Mastodon (500-character limit) from the platform buttons. Tweet Splitter splits your text and reserves numbering space accordingly. Copy each chunk and paste it into your post composer manually — Tweet Splitter never connects to any platform API.

What is a good free alternative to Typefully or Chirr App?

Tweet Splitter is a free, no-login alternative to Typefully, Chirr App, Hypefury, and similar paid tools. It does one thing extremely well: splits long text into a properly numbered tweet thread in seconds. No subscription. No watermark. Input auto-saved locally, never uploaded.

How do I convert a blog post into a Twitter thread?

Copy the key sections of your blog post, paste into Tweet Splitter, and click Split. The tool breaks text at sentence boundaries and numbers each tweet automatically. Then copy each tweet and post in sequence on X. For a full guide, see our blog post: How to Repurpose a Blog Post as a Twitter Thread.

Does Tweet Splitter work for LinkedIn?

Yes. Select LinkedIn from the platform buttons to use the 3,000-character limit. Tweet Splitter splits your long-form content into sequential posts with automatic numbering, perfect for LinkedIn carousel-style threads. Copy each part and post in sequence.

How does the smart split feature work?

Tweet Splitter uses the Intl.Segmenter API to detect sentence boundaries accurately. It splits at full stops, question marks, and exclamation marks. If a single sentence exceeds the character limit, it falls back to word boundaries — never cutting a word in half. This ensures every chunk reads naturally.

Can I add custom numbering to my threads?

Yes. Tweet Splitter supports three numbering modes: End (appends 1/N at the end), Start (prepends 1/N at the beginning), and None (no numbering). The tool automatically reserves character space for the counter so your content never overflows the platform's limit.
