What is on the store

The download counts below are the public Google Play badges, not a private estimate. Each app is published by Devanshu Studios.

PyMaster

Learn Python on a phone

Live on Google Play

PyMaster is a Python course for someone starting out. Lessons are arranged in a path, from a first program through variables, types, and input. Practice works offline. Progress is stored on the phone and synced when a connection returns.

A tutor inside the app answers questions today using Gemini. The lesson text itself does not depend on that call. The store lists 1,000+ downloads. The course has 1,200+ exercises.

Chakuli

Chat that stays on the phone

Live on Google Play

Chakuli is a chat assistant for someone who does not want the conversation sent to a server. The person picks an open model, including Gemma, and the model runs on the device. The store lists 100+ downloads.

Keepary

Scan and keep documents

Closed testing · production access requested

Keepary is a document desk for someone who wants scans, PDF tools, and signatures on the phone rather than in a cloud folder. It is in Google Play closed testing. Production access has been requested. It is not on the public store yet.

What is next

Two pieces of work are planned. Neither is shipped. The apps above are the products that exist today.

Planned · PyMaster

A tutor that explains the exercise in front of the learner

The tutor in PyMaster today uses Gemini. The planned change sends three things to Claude: the learner’s question, the exercise they are on, and what a correct attempt has to show. Claude returns a short explanation of that exercise, not a general essay. Lessons and saved progress stay on the phone. The current tutor stays in place until the new answers are better on the exercises already in the app.

Research · not published

Smaller models that can live where Chakuli already runs

Chakuli already runs open models on the phone. The studio’s research is smaller models of our own, measured on that same kind of device. No paper on that work is published. Chakuli will keep doing inference on the device.
