Key takeaways
- Free to start: OnePrep, PolyPrep and Origami. CookSAT, Crackd and UWorld offer trials or refunds, not free tiers.
- UWorld starts at $59 and teaches with video lessons, but has the smallest bank here at 1,700+.
- PolyPrep is free to start, then $29, $59 or $129 a month, with tests and daily AI chats rationed by tier.
- Crackd is paid only, $29 to $99 a month, and the $99 tier buys a private tutor you can text daily.
- Origami is the value pick: a free tier plus the lowest paid pricing ($14 to $29/mo) for a full platform with AI help.
- Best overall for most students who want real tests, AI feedback, and a plan without overspending: Origami.
Short answer: Three of these are free to start, OnePrep, PolyPrep and Origami. CookSAT runs from $19/month, Crackd from $29, and UWorld from $59, none of them with a free tier. Among full platforms, Origami is the value pick: a genuine free tier plus the lowest paid pricing anywhere ($14 to $29/month), including an AI tutor and real adaptive tests. Competitor prices here were checked against each site on 28 July 2026, and Crackd on 31 July 2026.
The field at a glance
The real split is not indie against legacy, it is who lets you practice at $0. OnePrep, PolyPrep and Origami have genuine free tiers. CookSAT gives you three days, Crackd gives you one mock and a three-day refund, and UWorld runs a trial. Here is how the six stack up, with every competitor figure checked against their own site:

The ones you can actually start free: OnePrep, PolyPrep and Origami
OnePrep is the deepest of the indie tools, 4,000+ human-written questions, its own AI explainer, and a 110-lesson course, with paid tiers sold per exam term. Origami matches it at $0 and goes further on the free tier itself: real two-module adaptive tests, a skill-level score report, and a taste of the Kami AI tutor, then cheap upgrades only if you want unlimited depth.
The paid indie: CookSAT
CookSAT is worth knowing for one thing the others do not offer: its Premium tier bundles two live tutoring sessions a week. It carries 2,800+ questions, a 650-word vocabulary trainer, and Desmos regression walkthroughs. There is a 3-day trial rather than a free tier, and Plus runs $24/month, or $19/month on the annual rate.
The gamified one: PolyPrep
PolyPrep is free to start (its Rookie tier), then $29, $59 or $129 a month. It carries 3,000+ official College Board questions plus 2,000 written harder than the real test, and leans on competition with head-to-head battle mode. The catch is that the tier decides how much you may use: 4 full-length tests and 10 AI chats a day at $29, 10 tests and 20 chats at $59, and unlimited attempts with 5+ hours a week of live lectures at $129. Read the full Origami vs PolyPrep comparison.
The tutoring one: Crackd
Crackd is paid only: one free mock, then $29/month for Plus, $49 for Pro and $99 for Premium, with a refund window of three days rather than a trial. The yearly rate is cheaper per month ($199, $399 and $599 a year), and the $14 you may see advertised is per week, not per month. Its bank is 4,000+ handcrafted questions across 29 modules, but the plan decides how much you use: 5 mocks on Plus and 11 on Pro, with the AI tutor starting at Pro and going unlimited only at Premium. What it sells that nobody else here does is a private tutor you can text daily, plus two live seminars a week, all run through Discord. Read the full Origami vs Crackd comparison.
The established brand: UWorld
UWorld's strength is teaching rather than volume: video lessons, thoroughly worked explanations, and an optional printed guide, starting at $59 with a free trial. Its bank is the smallest of the five at 1,700+ questions, and there is no AI explainer, so it suits students who would rather be taught a concept than drilled on it.
Where Origami wins on value
- Free to start, like the indies, no credit card for core practice.
- Lowest paid pricing of any full platform: $14/mo Plus, $29/mo Premium, and the free tier never expires.
- AI tutor built in (Kami), most competitors either gate this or don't offer it.
- Real Bluebook-format adaptive tests plus a skill-level score report that tells you what to fix.
The bottom line
Choose UWorld if you specifically want its taught video lessons, or Crackd if you want a private tutor on daily text and can pay for one. For nearly everyone else, students who want real tests, AI feedback, and a clear plan without overspending, Origami delivers the most for the least. Start free on Origami, or see the full pricing.
