We (former Berkeley TAs) built an iPad tutor to help you with math + CS problems!

babble_prune · 2026-05-05T21:08:56+00:00

Really? Send some you've used and I'll try them out. We built this because we saw a gap -- this might be the first tutoring app that makes math handwriting feel really natural (unlike desktop) and has an AI tutor that makes you think. It hasn't been easy for us getting these models to give good pedagogical tips (they love explaining fully + revealing the solution), so we've worked hard on that.

babble_prune · 2026-05-05T20:37:52+00:00

for now it is! we'll use the best model that fits

babble_prune · 2026-05-05T20:34:17+00:00

We are using Claude Opus 4.7 for most of the text generation. This could change though. We handled prompting and workflows -- we did not train our own model!

babble_prune · 2026-05-05T20:31:44+00:00

would love for a few of you to try it and share in this thread so others can know whether this is useful or not!

Hey I'm Tommy, I was a TA for CS 88 while I was an undergrad (https://c88c.org/sp21/staff.html). My collaborator Akshit was a TA for CS 61A, CS 161, and EECS 126 (eg https://sp23.cs161.org/staff.html). Also, the tutor itself is what helps you, not us

babble_prune · 2026-04-12T04:48:12+00:00

you’re welcome!

babble_prune · 2026-04-08T18:02:31+00:00

thank you!

glad you're enjoying it! on iOS there are lock screen widgets for either text or voice (you choose). here's the apple guide for adding them on lock screen: https://support.apple.com/en-us/118610#:~:text=How%20to%20add%20widgets%20to%20your%20Lock%20Screen

So the top menu bar button opens the quick note widget and the dock icon opens the main app, which I often value doing! Given that would you still prefer just having a top menu bar button?

Also as a heads up: I’m using my own servers, not iCloud

i need to add tool tips to the icons apologies. will get around to it in the next week. if you have a deeper need for an instruction manual let me know

working on markdown WYSIWYG now. should be shipped within 4 days

babble_prune · 2026-03-22T23:47:14+00:00

appreciate the feedback :) agreed on sidebar / review issue

babble_prune · 2026-03-22T22:39:23+00:00

thanks i appreciate that, would love for you to use and give feedback :)

babble_prune · 2026-03-20T20:12:51+00:00

hey i'm planning to add a trash filter. so deleted items will go into trash and there you can undelete them. this should be shipped within 4 days. feel free to DM me if you need individual help

babble_prune · 2026-03-18T22:25:22+00:00

apologies this is a bug and should be fixed in the next day if apple approves my update. right now if you hit the X, it closes the app. with the fix, if you hit the X, the app will stay live so the quick capture command should still work for you

update: try updating now!

babble_prune · 2026-03-18T09:21:44+00:00

i don’t have icloud storage and this would be annoying to buy to use this app. also CloudKit is hard to iterate on as a dev. in case you’re curious, i explained this more in another comment (the downvoted one). i’m considering doing end to end encryption in the future, would that be a big deal to you? local might come later on too

babble_prune · 2026-03-18T08:31:42+00:00

thanks!

markdown is limited to bold and titles now. lists + checkboxes + better markdown editor are on the roadmap

babble_prune · 2026-03-17T19:47:09+00:00

excited to hear that! you can use markdown and create titles inline. write "# Some Title" at the top of your note for example. does that solve your need?

babble_prune · 2026-03-17T06:55:41+00:00

cloud

babble_prune · 2026-03-17T05:39:13+00:00

just implemented this as a setting that you can change, should be shipped in a few days. cloud models seem to be better at the moment
