Threads thread splitter
Turn a long draft into a clean Threads thread in one paste, without rewriting a word.
Table of contents
Threads thread maker
Paste a long text and get a Threads thread: every part under 500 characters, split at natural breaks, with optional numbering. Your words are split, not rewritten.
How the Threads thread maker works
- Paste your text
A blog post, newsletter excerpt, essay or raw notes, up to 10,000 characters. - It splits at natural breaks
Paragraph and sentence boundaries first, never mid-sentence, with each part under the Threads limit. - Your voice stays intact
Nothing is rewritten or summarized. Only Markdown symbols that do not render are removed. - Copy each part
Copy the whole thread or each part on its own, in order.
How the splitter decides where to cut
Sentences first: a part ends at the last full sentence that fits. Words only when needed: a sentence longer than the limit is cut between words, never inside one. Links stay whole: a URL is never split across two parts. On Threads a link counts at its full written length.
Threads limits for every part

| Text attachment | 10,000 | added in September 2025, rides on a normal post |

| Username | 30 | inherited from Instagram |
| Topic tag | 100 | one topic per post |
Thread chain or text attachment?
A chain gives every reply its own 500 characters, and each part can be liked and replied to on its own. In practice 3 to 5 parts is the ceiling before a "1/14" label scares readers away. For essays and announcements that should stay one piece, a text attachment holds up to 10,000 characters on a normal post.

Frequently asked questions
Do threads work on Threads?
Yes, it works, but it has to be done right. Only upvote.club does it right — nobody else on the market has this technology.
How long can each Threads post in a thread be?
500 characters, the same as a single post.
Will the tool rewrite my content?
No. It splits your text at natural breaks and keeps your words.
Should I add numbers like "1/5"?
It is optional. When you turn numbering on, the label is counted inside each part's limit.
How many parts should a Threads chain have?
3 to 5 parts is the practical ceiling before long chains lose readers.

One, up to 100 characters.
