Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.

Studyflash is an AI study app that turns your own lecture slides, PDFs and notes into flashcards, quizzes, summaries, mind maps, podcasts and graded practice exams. Its AI tutor, Max, explains concepts from your uploaded sources and schedules reviews so you walk into the exam prepared.
Upload a lecture PDF, slides or notes and get flashcards, quizzes, summaries, mind maps, podcasts and practice exams generated in minutes.
Each card is scheduled based on how well you remembered it, so you review exactly what you are about to forget before exam day.
Max answers only from your uploaded sources and cites the passage each answer comes from, so you can verify every explanation.
Run timed, graded mock exams that can be modelled on a past exam you upload, so practice matches the real thing.
