One-page design · October 2026
A maths tutor in a phone for Class 6. It gives the next step, never the answer, and lets the student prove it to themselves.
The moment that matters
Answer apps hand over “20 cm”. It gets copied, then forgotten. Chirp hands back a smaller question. Two messages later Aarav adds the sides himself and hears “Spot on!”. That is the whole product in one exchange.
01 · Who it’s for
Stuck at 8 pm
Class 6, CBSE. Homework on a family phone. Stuck, and alone with it.

03 · Chirp
Meet Chirp
A curious sparrow who thinks with you.
Renamed from Riya, a common student name (“Hi, Riya. I’m Riya.”). 3D stills plus short clips; Reduce Motion shows the stills.
04 · Ask
One step at a time
Ask in your own words. Chirp replies with one small step and asks one question back.
A blank page, readyEvery launch opens a fresh chat. No menus to learn first.
Explain, then askThe app draws the rectangle itself and never prints the answer on it.
Check, then inviteThe working is checked before praise. Then: “Ready to try this idea yourself?”
- 30–90 words, 2–4 short paragraphs
- Ends with one question
- Never the final answer first
- Diagrams: fraction bar or rectangle, drawn by the app
- English, Hindi on request
05 · Photo
Snap the question
Neev reads the photo. It never solves it.
AttachSaved on the phone until it’s sent.
Read, then tutorA clear reading goes straight to Chirp.
06 · Try alone
Now try one yourself
A fresh problem every time, marked by code. Help is one tap away, and it counts honestly.
Have a go firstAnswer plus working. “Help is always here.”
Visual problemsCharts, number lines, tokens and shapes, all drawn by the app.
Never the same twiceUp to 80 tries to avoid repeats and numbers from the chat.
Celebrate, honestly“One success is early evidence, not mastery.”

Labels come from real attempts. The AI never makes up a score.

After one winPerimeter: Early evidence
Also: “Worth revisiting” (a later miss), “Not checked yet”, “Revisiting an idea”. Computed from the last 20 attempts. Hints, “Work with Neev” or “I used help outside Neev” count as helped. “Later” costs nothing. Thresholds not yet validated.
08 · How it’s built
The model talks.
Code keeps score.
AI explains and reads photos. Practice, marking, diagrams and progress are plain code.
