Plus
For the learner who shows up every day.
- Everything in Free
- About 200 lessons a month
One 30-day pool instead of a weekly one, so exam weeks can borrow from the quiet ones.
- Personalization that deepens over time
Your learner model is rebuilt every 7 days, so lessons get more tailored the longer you stay.
- 300 saved lessons, 30 playlists, bigger uploads
Higher caps everywhere, and dense documents go through in one pass.
- A Plus border and icon that stand out
A distinct border and profile icon wherever you show up in the community.
Premium 5×
5 times the room, and the models that earn it.
- Everything in Plus
- About 1,000 lessons a month
Exactly 5× the Plus pool, and about 23× the room of Free. A ceiling you would have to try to reach.
- Our flagship models, and a faster queue
The most capable models we run, for the material that actually resists you, and never served from the economy queue everyone else waits in.
- Personalization at its deepest
Your learner model is recompiled every 3 days by our strongest reasoning model, so it knows what you forgot before you do.
- Unlimited saves, playlists, and uploads
No caps on anything you keep, build, or bring in.
- Highest-quality document and image parsing
High-detail OCR for dense textbooks, diagrams, and handwriting.
Switch or cancel in two clicks. Everything you've made stays yours on every plan.

- Work on every plan, including Free
- No subscription required
Every capability, side by side.
Same engine on all four. What changes is how much of it you get, how fast it arrives, and how well it knows you.

Plan perks
The fine print, in plain words.
Is the free plan really free?
Yes. Free forever, no card required. About 10 lessons a week, refilling every 7 days, plus quizzes, flashcards, spaced review, streaks, and the full For You feed.
Can I cancel anytime?
In two clicks, from your profile. You keep access through the end of the period you already paid for. No emails, no phone calls.
What's the refund policy?
There's a 14-day money-back guarantee on paid plans. If the progress isn't there in your first two weeks, reach out and we'll refund you in full.
What are Sparks?
One-time top-ups for when you hit your plan's limit mid-session. They never expire, stack on any plan including Free, and don't change your subscription.
What happens when I hit my limit?
Everything you already made stays. New creation pauses until your limit refreshes, or you can use Sparks to keep going right away. On Premium Unlimited this question has no answer, which is the point of it.
What is the difference between Premium 5× and Premium Unlimited?
Both run our flagship models, the deepest personalization and the highest-quality parsing. Premium 5× gives you 5 times the Plus pool, which is roughly 1,000 lessons a month. Unlimited removes the pool entirely and adds the things you feel rather than count: a priority queue on every generation, 8 lessons building at once, a learner model rebuilt daily, and uncapped video lessons.
Is "unlimited" actually unlimited?
Yes. There is no pool, no monthly ceiling and nothing that stops you mid-session. We do run automated protection against scripted abuse, the same way any service does, and it is set far above what a person studying can reach. If you are a human being using Lernex to learn, you will never encounter it.
Can I switch plans later?
Anytime. Upgrades take effect immediately and are prorated; downgrades apply at your next billing date. Your learning history carries over either way.
Is payment secure?
Payments run through Stripe and support all major cards and digital wallets. We never see or store your card details.
