Kept running
Pay it forward.
Everything here is free to everybody. Always. But API calls and hosting cost money, month after month.
If you're a working practitioner and something here helped you, you can pay it forward — extend access for somebody who can't.
How it works
Every contribution extends the runway. When contributions cover monthly costs, the demos continue. When they don't, I fund them personally. Contributions don't keep the lights on — they decide how much personal funding is needed.
Demos never pause. When contributions don't cover costs, I fund them personally.

Or just use the tools. That's enough too.
Engaged, ongoing support matters most
One person paying ₹500 every month does more than ten people paying ₹500 once. Monthly contributions are predictable — they let hosting continue without me funding the gap personally.
If you're part of an institution that benefits from the tools, consider a standing monthly contribution. If Coherence or Fragment Mapper is useful inside an institution, that institution can contribute.
What we don't do
- No freemium tiers. The tools are free or they're not.
- No institutional licensing. An institution gets exactly what one person gets, and pays the same for it.
- No advertising or tracking. Your submissions are not stored, not used to train any model, and not sold or shared.
- No paywalls. Everything published on Koher is freely accessible — positions, reading lists, essays, all public, no login.
Data use
Submissions to hosted demos are processed in memory and discarded. No submission text and no model outputs are stored, and nothing you submit trains or fine-tunes any model. The only thing recorded per analysis is an anonymous usage event — a timestamp and an anonymous user_id — so the daily rate limit can be enforced.
