Pay it forward.
The tools are free for students. Always. But API calls and hosting cost money month after month.
If you're a working practitioner and a tool helped you, you can pay it forward — extend access for students who can't pay.
How it works
Every contribution extends the runway. When contributions cover monthly costs, demos continue. When they don't, Prayas funds them personally. Contributions are not optional — they simply decide how much personal funding is needed.
Demos never pause. When contributions don't cover costs, Prayas funds them personally. Contributions extend the runway.
Support options
₹500 ≈ 50 student analyses · Secure payment via Razorpay
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 Prayas having to fund the gap personally.
If you're part of an institution that benefits from the tools, consider establishing a standing monthly contribution. A design programme using Coherence Diagnostic? A game design classroom using Play Shape Diagnostic? Institutions benefit; institutions can contribute.
What we don't do
- No freemium tiers. The tools are free or they're not.
- No institutional licensing. Schools and universities access the same free tool as individual students.
- No advertising or tracking. Your submissions are not stored, not used to train any model, and not sold, shared, or used commercially.
- No paywalls. Everything published on Koher is freely accessible. Position statements, 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 is used to train or fine-tune any model. The only thing recorded per analysis is an anonymous usage event — timestamp and anonymous user_id — so the daily rate limit can be enforced.
