The Free-Tier Promise
Written before any paywall exists, so that when one does, it's built against a public commitment โ not an evolving internal guess.
Draft v1 ยท Last updated 2026-08-08 ยท Any change to this page is dated below, never silent
Everything that is free on ClipSAT today stays free forever. A future paid tier will sell convenience, coaching, and institutional tooling on top โ it will never move a proof, an explorer, or a chapter that is free right now behind a paywall.
ClipSAT has no accounts, payments, or paid tier today โ everything on the site is free. This page exists so that changes, whenever they come, get judged against a written promise instead of drifting. Treat this draft as pending Mr. Abdallah's sign-off before it's presented as final.
Free forever โ the non-negotiable floor
Every one of these stays free, for every user, with no login required, permanently:
- Every chapter, proof, and derivation, across all 21 tracksIGCSE, A-Level (AS & A2), AP Calculus AB/BC, AP Precalculus, AP Statistics, IB Math SL/HL, Calculus, Algebra, Algebra 2, Geometry, Pre-Calculus, SAT, ACT (both forms), EST (both forms), and Qudrat/Tahsili โ no track, current or future, is held back as "premium."
- Every interactive explorerAll canvas-based visualizations โ tangent lines, Riemann sums, transformations, and everything added going forward.
- Quiz generation and practiceRandomized chapter quizzes, difficulty filters, and the full question bank behind them.
- Mistake tracking on your own deviceThe existing "practice my mistakes" loop, stored locally in your browser.
- Published downloads and worksheetsEvery worksheet and answer key already published to a track's Downloads section.
What a future paid tier may add on top
None of this exists yet. If and when it ships, it will be genuinely new convenience layered on top of the free floor above โ never a feature that's free today, relocated behind a wall. This tier, informally, is ClipSAT Plus.
The trial and this price apply only to the Plus features listed below. Nothing in the free-forever list above is ever time-limited, trial-gated, or affected by whether a Plus trial has been used or expired.
- Step-Coach, the AI tutorConstrained Socratic hints against ClipSAT's own worked solutions and proofs.
- Unlimited mock exams with predictive scoringE.g. an estimated AP score band or Tahsili percentile, shown with a confidence interval, not a guarantee.
- Spaced-repetition schedulingAutomatic review timing for the existing flashcard/active-recall feature, instead of manual review.
- Printable packet exportsFormatted, downloadable practice packets beyond what's manually published today.
- Institutional toolingPer-seat licensing, teacher/parent dashboards, and LMS integration for schools and districts โ priced separately from the individual tier and never a condition of the free floor above.
The vow
If a paywall is ever built, whatever is free the day before it ships stays free after it ships. This page will be updated with a dated note describing the change, not silently edited.
ClipSAT Plus is priced at $20/year, after a 30-day free trial โ anchored to be affordable for a self-motivated individual student first, reach over margin, especially early on. That price applies to Plus only; it is never a cost of the free floor above.
A lapsed or unpurchased Plus trial never locks you out of the free floor. It ends the trial's extra features and reverts your account to everything in the free-forever list โ never to a blocked or paywalled site.
If this promise is ever broken, that's a bug in ClipSAT's word, not a pricing decision โ and it should be reported the same way any other bug would be.
