In development
You need this for two weeks. Not twelve months.
Finals are in nine days. A monthly subscription you'll forget to cancel is the wrong shape for that, and we know it — most people who use this tool use it hard for one night and then don't come back for a month. So: a pass. Fixed window, unlimited solving, one payment, nothing to cancel.
No account, no card. One email when there’s something to show you.
Why a pass instead of a subscription
We looked at how this tool actually gets used, and it was humbling: most people who solve anything do all of it on a single day. Not because they hit a limit — because the assignment ended.
That's not a broken user. That's a real pattern: work comes in bursts, panic comes with a date attached, and then it's over until the next one. Selling a monthly subscription against that is selling the wrong container, and it mostly means people either don't buy or buy once and resent the second charge.
What we think it looks like
- A fixed window — something like 7 or 14 days, starting when you activate it, not when you buy it.
- Unlimited solving inside that window. No counting, no running out at 1am the night before.
- One payment. It ends by itself. There's nothing to cancel, so there's nothing to forget to cancel.
- Buy another one next time, if there is a next time. No hard feelings if there isn't.
What we don't know yet
These are genuinely open, and the note field above is where you get to answer them:
- How long? A week covers a finals push. Two weeks covers a revision run-up. A month is basically the subscription again.
- What's it worth? Somewhere between a month of Student ($4.99) and a month of Pro ($9.99) is our guess, but a guess is what it is.
- Does "unlimited" need a ceiling? Probably, for abuse reasons — but set high enough that nobody studying normally ever sees it.
Meanwhile
The free tier is 20 solves, no card, no account needed to start — enough to get through a problem set tonight. If you want it now rather than when the pass ships, start there. If your exam is further out and you want the honest low-cost option, Lite is $1.99/month and covers a weekly set.
This doesn't exist yet — today there's a free tier and monthly plans. We're working out whether a fixed-window pass is what people actually want before we build the billing for it. Tell us and you'll be first to know.
