Same algorithm as the free web version. Now for power users: process folders from the command line. Offline, private, pay-what-you-want.
Split an entire folder of articles in one command. No more pasting one-by-one.
Identical semantic splitting as the free web version. Lexical cohesion, not word count.
Every input file becomes a separate _topicsplit.md with ### Topic N headings.
No server, no API key, no tracking. Runs on your machine. Your data never leaves.
Adjust from 0.0 (few segments) to 1.0 (many granular segments). Find your sweet spot.
Install via pip. Pipe text in, split it out. Integrates with any shell script or automation.
One line, any system with Python 3.9+.
Get clean segmented markdown.
Split every article in a directory at once.
TopicSplit Pro is pay-what-you-want. Minimum $5 unlocks the CLI. More = more tools built.
Web-only, single paste
Everything in free, plus:
After paying, install via pip — no license key needed. Honor system.
There's no license key. Buy on Ko-fi or PayPal, then pip install topicsplit-pro. It's honor system. The tool checks nothing — trust.
Email me (find it on the GitHub repo) — I'll refund. This is a human-scale operation, not a SaaS.
Yes. MIT license. Use the output however you want. Pay once, use forever.
I want the tool accessible to students and hobbyists, but I also need to eat. $5 minimum keeps the project alive. If you value it more, pay more. If $5 is a stretch, use the free web version.
Not yet. If you need custom integration, custom algorithm tweaks, or priority support, email me. I'm open to it.
