A product studio in India

We build the whole product.

Philotium designs and engineers web apps, iOS and Android apps, and the AI inside them — chatbots that win leads, retrieval systems that answer from your documents, OCR that turns paper into data — end to end, from the first sketch to the listing on the App Store and Google Play.

ExamGraph, our first product

A NEET exam room, on a screen, before the exam moved there.

NEET-UG becomes a computer-based test from 2027. ExamGraph’s mock papers already ran in the NTA question palette, because it was the right way to build a mock paper either way. It is the component the app runs, not a mock-up drawn for a page.

  1. The same screen, the same squares.

    One hundred and eighty questions, one hundred and eighty minutes, and the five-state palette a candidate reads under pressure: answered, not answered, marked, answered and marked, not visited.

    ExamGraph’s question palette mid-paper: answered, not answered, marked, answered and marked, and not visited, with a count for each.

  2. Every answer lands in one place.

    A topic test, the daily ten, a full mock, a custom paper, a past paper: all of them write one line of history and one chapter score. Graded on the server, never in the browser.

    ExamGraph’s History page: every mock and topic test in one list, each with its score.

  3. MITRA opens your results before it opens its mouth.

    The tutor reads the student’s record first, quotes the NCERT line with its page number, and ends every answer in a button that builds the test it just argued for.

    MITRA explaining the laws of motion and citing the NCERT Physics chapter and page.

  4. A path, and a vault for what went wrong.

    Ascent walks the 72 live chapters in the order the exam weights them; its stars are real mastery, so they decay. The Mistake Vault brings every wrong answer back at 1, 3, 7, 16 and 35 days.

    The Ascent: chapters as steps up a mountain, with stars for mastery and the next step marked.

  5. Where you stand, and who you sit with.

    An opt-in leaderboard, national and by state, with one rating out of 720. Circles: up to thirty friends sitting the same paper, one board per paper, no chat by design.

    ExamGraph’s leaderboard: national rank, percentile and a rating out of 720, with national and state boards.

OpenLobe, in beta

Type a topic. Get a path built from the best teachers on YouTube.

The best teachers are already on YouTube; you just cannot find them in the right order. Give OpenLobe a topic or a plain-English brief and it lines up videos so each one builds on the last, with a diagnostic first and a quiz at the end of every module.

Invite-only beta, free while it lasts. Access is granted on request.

Real videos from public YouTube channels, shown as examples of what OpenLobe curates. The creators are not affiliated with us.

  • It checks what you know first

    A short diagnostic before anything is built, so the path fits you and not the average learner.

  • Videos matched to subtopics, a quiz per module

    Each module is a handful of curated videos on one subtopic, practice you actually write, and a quiz that decides what comes next.

  • A tutor that knows the module

    Ask about the part that did not click; the tutor has the module in front of it.

What we build

One team, from the sketch to the store.

AI for companies

  • Intelligent chatbots

    Assistants that live in your site or product, answer from your data, qualify and capture leads, and trigger the next step in your workflow — a CRM row, a booking, a ticket, a follow-up.

    Proof. MITRA reads a student’s record, answers with citations and ends every reply in an action button.

  • RAG and knowledge systems

    Retrieval-augmented answers grounded in your documents, with citations you can check, streaming, caching and a cost ceiling.

    Proof. ExamGraph’s NCERT layer: 4,185 passages, citations substituted server-side so a page number can never be invented.

  • OCR and document extraction

    Paper, scans and PDFs turned into clean, structured, searchable data, with a review gate before anything is used.

    Proof. 20k+ NEET questions digitised from 19 books; figures cropped and reviewed; maths converted to KaTeX.

Products, end to end

  • Web apps

    Next.js and React products with real backends: auth, data, payments, the lot.

    Proof. ExamGraph and OpenLobe run this way in production.

  • iOS and Android apps

    Native and store-ready, published under our developer accounts or yours.

    Proof. Enrolled on both stores; OpenLobe’s iOS app is in build.

  • Design, data and launch

    Design systems and UI engineering, Postgres with row-level security, payments, and the release itself.

    Proof. Both products’ billing, RLS and release pipelines.

How we work

Four steps, no surprises.

  1. Brief

    A week of questions and a written scope you can hold us to.

  2. Prototype

    A clickable build in the first two weeks, so the conversation is about something real.

  3. Build in the open

    A weekly demo, a shared repository, and decisions written down where you can read them.

  4. Launch and run

    Store submission, monitoring, and a handover you can actually read.

Stores

Registered on both stores.
