Our take
Summarize a recording you already have on your own computer. Use a live notes app when the class is an online meeting.
Choose local if…
- The lecture is private
- You already have the file
Choose cloud if…
- You want notes during the class
- The class is a video call

Questions
- Does this upload my files?
- The local tools on this page don't upload your files. The cloud options in the comparison do.
- What does it cost?
- Most options are free. A few apps are a one-time purchase, and a few models need a computer with more memory.
- What if it will not fit?
- Use Check my computer, or turn on the lighter memory filters. A red light on the model page means the file is too big.
