Kelvi Family
NewFor children and caregivers
A K–8 math path that never leaves an idea behind. Concepts return in new problems—a little deeper each time—so your child builds lasting understanding, not just checked boxes.
Discovery-based mathematics
Kelvi is a human-centered mathematics platform that uses AI to help learners develop ideas through conversation—at home, in school, or with a problem of their own.
Piloting at schools across the US and India.
A real exchange
Kelvi reflects the learner's idea and asks what follows—without praise, a score or a verdict.
I can see you've noted the scale (1 : 6,480,000), calculated the map area as 8.6 × 5.4 = 46.4 cm², and you've mentioned wanting to scale it up.
One thing to think about before you finish that sentence: the scale applies to lengths. When you scale an area, what happens to the scale factor?
You're using the square of the length scale for area.
What does that make the area scale factor?
Real personalization
Two learners can give the same answer while seeing entirely different mathematics. Kelvi listens for the strategy, representation and connection underneath the result.
The same commitment to mathematical thinking, designed for three different learning contexts.

Kelvi School
For teachers and classrooms
Create discussion-based mathematical experiences and see the ideas, strategies and connections students are developing—not only what they scored.
Active pilots in the US and India.
Kelvi Open
For middle and high school students
Bring a mathematical question or a photo of your work and think it through with Kelvi, one question at a time.
Kelvi Family · K–8
Ideas resurface on purpose—mixed with new ones and growing in depth—because real understanding develops through connections, not completed topic boxes.
Already set up? Child login →
Begin with a situation—not a topic label or a procedure to copy.
Try a strategy and put the emerging thinking into words.
Examine another child’s strategy and make connections.
Connect the discovery to mathematical language and notation.
Return to the idea later, mixed with others and growing in depth.
Kelvi School
Kelvi School supports discussion-based mathematics without taking instructional judgment away from the teacher. Students develop and explain ideas; teachers see the thinking behind the work.
Create mathematical experiences designed for discovery, explanation and classroom conversation.
Surface student strategies and connections rather than reducing learning to a single score.
Kelvi supports the teacher’s decisions. It does not replace the teacher or prescribe what must happen next.
Currently piloting at schools across the US and India.
Kelvi Open
Kelvi Open is for middle and high school students who want to talk through a mathematical idea, share a photo of their work and remain responsible for the reasoning.
Start with the problem you are already working on.
Kelvi asks the next question instead of handing over the next answer.
Work through the reasoning yourself instead of copying a generated solution.
A note from the founder
As a teacher at Phillips Exeter Academy and as a parent, I grew tired of seeing a student's learning reduced to a number. Around a Harkness table, I see everything that number leaves out: students testing ideas, articulating partial understanding, listening to one another, and making mistakes that move the conversation forward. Mathematics becomes a language they can speak—not simply a collection of procedures they are expected to reproduce.
I wanted every learner to have that experience. So I created Kelvi from an asset-based belief: learners arrive with ideas worth hearing, and teachers bring judgment worth preserving. Kelvi begins with what the learner already sees, asks the question that helps the idea develop, and adds support only when it is needed.
The goal is not to deliver answers faster. It is to help learners understand, articulate, and take ownership of their mathematical thinking.

Kelvi is shaped in close collaboration with Mehak Mahajan—co-conspirator, lead UI/UX designer and thought partner—and through ongoing conversations with learners, families and educators.
Kelvi Family is a flexible, problem-first K–8 curriculum for children working independently after caregiver setup. Mathematical ideas return over time, mixed with other ideas and growing in depth. Kelvi School is for teachers and classrooms. Kelvi Open is for middle and high school students bringing a mathematical question or their own work.
