Mathematics meets performance in v0.8.8. We've completely revolutionized how Lernex renders equations—swapping MathJax for the blazing-fast KaTeX library—and introduced new AI providers that make Pro users' lessons generate faster than ever. This is math, reimagined.
Beautiful equations shouldn't come at the cost of performance. That's why we've migrated from MathJax to KaTeX—the fastest math typesetting library available. The difference isn't subtle; it's transformative.
Whether you're studying calculus derivatives, physics equations, statistical formulas, or chemical notation—every mathematical expression now appears instantly. No more waiting. No more jank. Just crisp, beautiful math the moment you need it.
For our Pro users, we've integrated new AI providers specifically optimized for educational content generation. The result? 40% faster lesson generation without any compromise in quality.
Pro users now experience lesson generation in under 3 seconds on average—keeping you in the flow of learning without frustrating wait times.
We're constantly evaluating new providers and models, always searching for the optimal balance between speed, quality, and cost. Your learning time is precious—we refuse to waste it.
Great products are built from countless small refinements. This release includes dozens of improvements that collectively elevate the entire experience:
Streamlined lesson rating system
More accurate usage tracking
Refined visual details throughout
Faster loads, smoother animations
Transparency builds trust. We've completely reworked usage limit tracking to be fairer and clearer. The analytics page now shows exactly where you stand—no guesswork, no surprises.
We've also fixed edge cases where limits weren't being tracked correctly, ensuring everyone gets exactly the learning time they're entitled to. Our goal remains simple: maximize your learning while keeping Lernex sustainable.
Many of these improvements originated from your feedback. Every bug report, feature suggestion, and comment shapes what Lernex becomes. Keep sharing your thoughts—we read every single message and take them seriously.
STEM learners, this one's for you. Equations have never rendered faster or looked better. Open a math-heavy lesson and experience the difference yourself.
Mathematics, perfected.
