NotebookLM is one of the best and most useful AI platforms out there, but once you start using it regularly you also feel its limitations leaving something to be desired more.
- There are limits on the amount of sources you can add in a notebook.
- There are limits on the number of notebooks you can have.
- You cannot have sources that exceed 500,000 words and are more than 200MB.
- You are vendor locked in to Google services (LLMs, usage models, etc.) with no option to configure them.
- Limited external data sources and service integrations.
- NotebookLM Agent is specifically optimised for just studying and researching, but you can do so much more with the source data.
- Lack of multiplayer support.
...and more.
SurfSense is specifically made to solve these problems. SurfSense empowers you to:
- Control Your Data Flow - Keep your data private and secure.
- No Data Limits - Add an unlimited amount of sources and notebooks.
- No Vendor Lock-in - Configure any LLM, image, TTS, and STT models to use.
- 25+ External Data Sources - Add your sources from Google Drive, OneDrive, Dropbox, Notion, and many other external services.
- Real-Time Multiplayer Support - Work easily with your team members in a shared notebook.
...and more to come.
