Try SynapseΒΆ
The whole app running in your browser with no server and no account. It starts loaded with a small example workspace (a few MIT OpenCourseWare courses). Everything you do stays on this device.
A few things to try:
- Open a course, read the annotated lecture PDF, add a highlight or a note.
- Generate exercises from a document (needs an AI key, set in Settings > This device; the demo works without it, you just won't get generated questions).
- Watch the progress page fill in as you answer.
- Export your workspace from Settings > Backup & sync, and import it into the installed app later.
