Spotter

A coding gym: practise without AI, spotted only when stuck

Should you build this?Build it

Paid coding practice has proven buyers, and Adarsh's college-club and X reach can get the first users.

The problem

Beginners who lean on AI to write their code never build the skills to write or debug it themselves, and Indian juniors are asking where the struggle that used to teach them went.

Writing code, hitting an error and fixing it by hand is how people learn to program, and AI tools now skip that step. Students and first-year developers pay for it in weak interviews and in being unable to judge whether AI code is correct.

The idea

Spotter gives you a 20-minute daily coding problem in a browser editor that blocks paste and AI, and it only offers hints once you have been stuck for a while.

1Open today's problem, picked from your college syllabus (C, Python, DSA), and type your own solution.
2Stuck for 10 minutes? Ask for a hint. They start vague and only get more specific if you stay stuck.
3Solve it and get a shareable proof card showing a replay of you typing it.

Price: Free: 3 reps a week. Pro: ₹149 a month or ₹999 a year, with unlimited reps, the hint ladder, proof cards and squads. Later: a club licence of about ₹2,999 a semester for running No-AI Nights.

Who paysThe student (or a parent) pays about ₹149 a month, or ₹999 a year, by UPI. Tech clubs run free group sessions that feed paid signups.

Who uses itCS students and first-year developers in India learning to code, including complete beginners struggling with C, Python and basic DSA.

First 10 usersAdarsh posts a 7-day no-AI C or Python challenge on X and LinkedIn with proof-card replays as the hook. He asks Kolkata GDG on Campus and Takshila leads to host a No-AI Night in their lab and signs up attendees on the spot. He also replies with specifics in r/developersIndia threads on juniors and fundamentals. He offers a ₹499 six-month founding plan to the first 10 and spotters those 10 by hand over WhatsApp.

Why not just AIThe learner who wants to struggle is the same person who will type 'just give me the code' at 1am, so an agent with a tutor skill can still cave. A proof of unaided solving has to come from a third party, not from the learner's own agent. An agent also has no aggregate data on where thousands of Indian beginners get stuck on the same syllabus problems, and it can't give you a squad of peers to explain your code to.

[ How to start ]3 steps

01
Build the no-paste editor with typing replay for C and Python first.
02
Run a 7-day no-AI C challenge on X and LinkedIn; track signups.
03
Book one No-AI Night with a Kolkata GDG or Takshila lead.

[ Inspired by ]What it borrows, and what's different

Boot.dev
A gamified, paid path with streaks and XP that keeps learners practising. Boot.dev is dollar-priced, backend-only and AI-on. Spotter is rupee-priced, built on Indian college-syllabus problems, and its point is deliberately removing AI.
Receipts
Keystroke replay as proof a person wrote their own essay. Receipts is for essays and defends against accusations. Spotter applies replay to code, as a positive learning record that recruiters, club leads and seniors can check.
CodeTrain
A tutor that asks questions and never writes the learner's code. CodeTrain targets engineering teams working in their own repos and relies on the learner's own agent. Spotter targets zero-to-one students with an enforced editor, hints drawn from many learners' stuck-points, and a peer squad.
