Free credits for your students

We issue a batch of one-time codes for your course. You hand one to each student; they redeem it on their own account and get a large prepaid balance — enough to work through a whole course without thinking about limits. There is no plan to manage, nothing to cancel, and no card involved at any point.

1. 1

   Tell us about the course

   Send a message with your institution, the course, and roughly how many students. That is enough for us to size a batch.

2. 2

   We send you the codes

   You get a list — one code per student. Hand them out however suits you: a slide, a handout, the course page.

3. 3

   Students redeem their own

   Each student signs up free, opens Billing, and enters their code. The credits land on their account immediately.

How the codes work

• One code per student. Each code works exactly once, so a code that leaks costs one grant and nothing more.
• Students redeem on their own accounts — there is no shared class login, and their work stays theirs after the course ends.
• Credits do not expire once redeemed. A student keeps what they were given, including after they graduate.
• Codes themselves expire a year after issue, so an old handout cannot be redeemed indefinitely.
• A student may redeem more than one code, so a short workshop now does not rule out a full semester grant later.
• No payment details are ever required — not to sign up, not to redeem.

What to include

So we can size a batch without a round-trip, mention:

• Your institution and your role
• The course, and roughly when it runs
• How many students you expect

Send us a message and we will get back to you with codes. Get in touch .

Are you a student?

Ask whoever teaches the course to write to us — we issue codes to institutions rather than individually. In the meantime the free tier needs no card, and the playground needs no account at all. Try the playground .
