Stability & Performance Update
Whatās New?
Weāve been working hard to make Cubrain even more reliable and faster. This update focuses on performance optimization and a more engaging processing experience.
š Performance & Optimization
- Batch Processing: We now group 5-10 highlights into a single AI prompt. This significantly reduces API costs and speeds up the generation process by up to 60%.
- Async Queue System: A new background processing system ensures that large PDFs donāt time out. You can now track your progress in real-time.
- Empty File Validation: Added strict validation for file uploads. No more āghostā decks from empty or unreadable PDFs!
š Visual Progress UX (The Pacer)
Weāve introduced āThe Pacerāāa real-time character animation that reflects the processing state.
- Running: When AI is actively synthesizing your cards.
- Success: When your deck is ready for review.
- Purpose: Weāve turned technical latency into an entertaining visual element to keep you engaged while you wait.
š”ļø Stability & Subscription
- Grace Period Logic: Pro users now have a 3-day grace period after their subscription expires before losing access to premium features.
- Supabase Auth Refactor: Improved session management for a more stable login experience.
š Bug Fixes
- Fixed a layout shift on the landing page when the launch banner was active.
- Improved the real-time counter for the early bird discount.
š ļø Under the Hood: Batching & The Pacer
To handle the massive textbooks used by Med and Law students, we implemented a Vectorized Batching strategy. Instead of processing highlights one-by-one (which is slow and expensive), we group related annotations into a single high-context prompt.
Additionally, weāve decoupled the AI processing from the web request using an Asynchronous Task Queue. This is why you see āThe Pacerā animationāitās not just a decoration, but a real-time listener to our backend queue, ensuring that even if a synthesis takes 30 seconds, your browser connection remains rock-solid.
