Company

We’re building the explain key for every screen.

tintlo is a Mac and Windows app. Drag a box around anything on your screen, ask out loud, and tintlo explains it by drawing on it: circles, arrows and labels, right where you're looking.

Don’t get it? tintlo it.

The problem

The AI can already read screens. What’s missing is an assistant that answers on the screen.

A chart in a report. An error in the code. A figure in a paper. A slide ten minutes before the exam. Today people take a screenshot, paste it into a chatbot, and get back a wall of text that never says which part of the screen it means. Then they switch back and try to match the words to what they see.

The team

Three founders. One obsession.

Product, distribution and community, each owned by one founder from day one.

Co-founder & CEOIntelligent Manufacturing Engineering · Xi'an Jiaotong University

Mujtoba leads tintlo's product, design and growth. He has spent years designing and shipping products across software, AI, real estate and manufacturing, and he is the Managing Director of a real estate development company in Bangladesh with commercial and residential projects. He knows what it takes to run a business with real customers, real payroll and real deadlines.

He studies Intelligent Manufacturing Engineering at Xi'an Jiaotong University, one of China's leading engineering universities, where the discipline is designing whole systems rather than single parts. That is how tintlo is built: capture, reading, reasoning, drawing and memory, designed as one experience.

tintlo lives or dies on one second: the moment someone goes from lost to “oh.” Mujtoba designs for that second, and has the operating experience to build a company around it.

Co-founderLaw · University of Nottingham

Radeen leads community and retention. He builds the spaces where tintlo's earliest users gather, the referral and ambassador programmes that turn them into advocates, and the first-week experience that turns a download into a daily habit.

He studies Law at the University of Nottingham and brings that rigour to the parts of tintlo people have to trust: privacy, data handling and a clear line on academic integrity. In a product that looks at your screen, trust is the growth strategy.

Growth that lasts comes from people who stay and bring friends. Radeen owns both: the community, and the trust that makes it safe to join.

Co-founderEntrepreneurship · UCSI University, Malaysia

Nafis runs the engine that gets tintlo seen: short-form video and the creators who make it. Every tintlo answer is a drawing on a real screen, which makes each one a ready-made clip. Nafis turns that into a daily publishing rhythm, a creator program and launch campaigns built to travel.

He studies Entrepreneurship at UCSI University in Malaysia, and he belongs to the audience tintlo launches to first. He knows what students watch, what they share and what they scroll past, because it is his own feed.

Consumer apps are won on distribution. Nafis owns ours from day one, and he is building it with the people who will use it.

Why this team

We are the first user

All three of us are students today. tintlo launches to students first, and we are building it for the version of ourselves stuck on a problem at 11:40 pm.

One owner per lane

Product, distribution and community each have exactly one owner. Decisions are fast, because nobody has to guess whose call it is.

AI-native by default

We design, build and test with AI tools every day. It keeps us fast and lean, and it makes us exactly the kind of user tintlo is for.

What we believe

Four rules we build by.

Explain, don't just answer

tintlo is built to help people understand, not to do their work for them.

Your screen is yours

Process only what you select. Send only what the answer needs.

Calm beats clever

A lost person needs clarity, not features.

Show, don't tell

If we can draw it, we don't write a paragraph.

For investors

Build the next verb with us.

We’re speaking with early investors who back consumer AI, education and desktop software. If that’s you, we’d love to talk, and we’ll share our deck and plan.
