How it works

Three steps. Fifteen seconds.

No AI rewriting your words. No login. No server. 100% private — everything runs in your browser.

01

Paste your text

Drop in anything — WhatsApp, notes, rough draft. Writing quality highlights appear instantly. The hook analyzer flags weak openings and suggests 3 rewrites.

02

Pick platform or Repurpose All

Format for one platform with full control, or hit Repurpose All to generate 6 platform-optimized versions simultaneously. Viral Score tells you what's working.

03

Edit, export and post

Every card is editable inline. Export any post as a shareable image card. Copy individual posts or everything at once. History is always recoverable.

Why ThreadFormatter

Built for creators who already have the content

Every day, millions of creators write something valuable in their notes app or WhatsApp — then spend 20 minutes manually reformatting it. ThreadFormatter takes what you already wrote and formats it correctly for each platform, instantly.

Unlike Typefully or Chirr App, ThreadFormatter requires zero signup. Open, paste, format, copy. V2 adds Bluesky support, Substack Notes, hook analysis, viral scoring, image export, templates, and repurpose-all — all 100% free, all running locally.

FAQ

Common questions

A Twitter thread formatter takes your long text and automatically splits it into individual tweets of 280 characters or fewer. Use the target count slider to specify exactly how many tweets you want — the formatter adjusts density automatically.
Yes! V2 adds Bluesky support with 300-character post splitting, thread numbering, and an Open in Bluesky button that uses the official intent API.
Substack Notes is like Twitter for Substack writers. Our formatter creates hook-first, conversational posts optimized for the Notes feed, with an optional subscribe CTA.
The viral score is 100% rule-based (no AI). It checks hook strength, thread length, CTA presence, filler word density, sentence variety, and more. Each check passes or fails with clear feedback.
One click generates platform-optimized output for all 6 platforms simultaneously. Each gets the right format, character limits, and tone. Copy each one individually.
Never. All formatting and writing checks happen entirely in your browser. No text ever reaches our servers. History uses browser memory only and clears when you close the tab.
