The unit of work
A question thread
Subject, grade, points, answers, comments. One record that web and the apps share. Tomorrow’s student should land here instead of posting again.

Find last night’s answer before you post tonight’s
The product is a homework Q&A community for school students. Someone stuck on a problem searches the archive. If a worked explanation already exists, they use it. If not, they post. Classmates, teachers, and subject specialists reply. Useful answers rise; a verified mark is stored on the thread, not only in a chat that disappears.
Copy and photographs on this page are original to Omnisense360. They describe the model we shipped. They are not taken from the client’s marketing pages, app store listing, or UI. The India site is built around board subjects (including CBSE) and book-level solutions, plus a phone app that can photograph an exercise.

From the basics
What does this website actually do?
It is not a school LMS and not a paid tuition marketplace first. It is a public library of homework threads. The student comes in stuck; the product’s job is to get them an explanation without creating the tenth copy of the same NCERT exercise.
India-specific
Book-level solutions
Worked steps tied to books students actually carry — board subjects plus exam-prep titles. Search by book, not only by free text.
Phone
Type, photo, or voice
Most students arrive on a phone. Photograph the exercise, land on a community thread, read a checked explanation. Same archive as the website.
How a student uses it tonight
- Search before you postType the problem, or a few distinctive numbers. OpenSearch should surface near-duplicates. If an old thread already has a worked solution, stop there.
- Still stuck — askPick a subject (Math, Physics, Biology, Hindi…). Asking spends points. That tax exists so the feed is not spam. Attach a photo of the page if the algebra is messy.
- Wait for the communityPeers answer for points and rank. Moderators and subject experts mark a reply as verified. Votes push the useful explanation up — latest comment does not win by default.
- Come back on webThe Android ask at 21:14 is the same GraphQL object on brainly.in in school the next day. No re-ask.
Who else is on the site
Not only the kid with the homework
People who answer (other students, teachers, volunteers) earn rank. Parents and schools have their own doors in. Written conduct rules matter: without a moderation queue, a homework site becomes an answer-key dump.
A first-time visitor should see the shape of a thread — question, subject, replies — before they create an account.
Business model
Free archive, then paid plans
The library of old threads is the moat. Revenue is the right to skip ads and caps — and, at the top tier, a live specialist when the archive is not enough.
01 · Free
Search + ask with limits
Anyone can search and join. Ads and a cap on how many full explanations you see keep the lights on. Points make answering a game so the library grows without paying every reply.
02 · Paid
Unlimited answers, fewer ads
Subscription for students who hit the free wall mid-homework. Same community content — just not gated after the third click. This is the volume SKU.
03 · Live help
A person when the thread is not enough
Top plan includes the paid archive plus a monthly bag of live sessions with a vetted specialist (core science and maths, middle school through college). Chat, diagrams, follow-ups. A queue, not a named private teacher.
04 · AI + scan
Instant path, same index
Camera OCR and an AI explainer sit on top of the community corpus. They should retrieve an existing verified answer when one exists — not hallucinate a fifth quadratic. That is why OpenSearch is in the stack, not only a chat model.

Ranking
Verified beats newest
Latest comment. Points as a toy. Experts drowned.
Votes + expert flag + moderation states. Green check is a field, not a sticker.
Clients
One schema, three apps
Web, Android, iOS each waiting on a different PHP shape.
React + Kotlin + Swift talk to the same GraphQL/Apollo gateway.
Technologie
React and native apps on one GraphQL contract.
Web is React. API is a GraphQL / Apollo gateway on Node.js, still talking to existing PHP services. Mobile is native Kotlin and Swift with Apollo clients. Search is OpenSearch. Hosting and jobs sit on AWS.
That mix exists because a homework thread is a document (question, answers, votes, attachments, moderation) that three clients must read the same way — and because “similar question” is a search problem, not a JOIN.

What the community can do now
Fewer clone threads
The quadratic posted at 19:00 is a search hit at 21:14, not thread number eleven.
One field, three clients
Verified flag ships once on GraphQL. Web, Android, and iOS consume it.
Moderation has a queue
Conduct rules are not a PDF in the footer. Report is a state machine. Ban is a user flag.
