Frequently Asked Questions

Everything you need to know about Notlo.

Is Notlo really free to use?
Yes, completely! Notlo is built by a student, for students. We operate on a generous free tier of **5 notes per day** using our shared API keys. If you want unlimited study materials, you can easily save your own free Groq API key in the settings, allowing you to use Notlo infinitely for free!
What kinds of files can I upload for transcription?
Notlo supports standard audio formats (MP3, WAV, M4A), course slides and textbook PDFs, and public YouTube video links. For visual learners, our Syllabus Exam Prep engine even processes uploaded curriculum images using high-end Llama Vision OCR models!
Are my custom API keys secure?
Absolutely. Your custom Groq API keys are stored entirely inside your browser's local sandbox storage ('localStorage'). They never leave your device and are sent directly to the AI inference engine over HTTPS, ensuring your credentials remain 100% private.
Does the study note generator suffer from time outs?
No! Most AI study tools crash on long lectures due to serverless execution limits. Notlo utilizes a proprietary client-side segmentation pipeline that breaks long transcripts into smaller chunks and compiles them sequentially, ensuring reliable, timeout-free note generation.

"I built Notlo because I was tired of manually summarizing textbook chapters and copy-pasting definitions into flashcards. Most online study tools either restrict basic features behind expensive paywalls or crash on long lectures.

Notlo uses local client-side segmentation to compile massive syllabi reliably. It is built as an honest, direct utility to help you study more effectively."
