The math kid
Hi, I am Ankit, one of the creators behind Matharium, a project you can now find on most social platforms, Pinterest included.
Growing up, I was one of the cool kids in math. I scored perfect marks, and yes, I was the math teacher's favourite too. My mom taught math at a primary school, and my interest in the subject started with her. In grades 6 and 7, my benchmate and I would crack problems from the next chapter while our teacher was still teaching the previous one to the rest of the class. Thank you, Kumar Rana of Chirag Higher Secondary School, for what you taught me and for keeping the math alive in me. I am grateful to have been your favourite student.
Losing it, and watching AI take it
Around grade 9, I slowly lost my taste for math. I kept finding excuses to get away from it, and eventually my scores dropped too. From math geek I drifted into astrophysics, then into CS and AI, and I always felt I had lost that bright kid who was curious enough to solve math problems.
Watching AI's progress in math now, I feel both sad and optimistic. Models are solving long-open Erdős problems and starting to approach the Millennium ones. It is sad for the researchers who worked tirelessly on these problems for years; some of them may well have been making progress, who knows? AI has been brutal here, taking the credit, the research jobs, and, worst of all, the research itself. At the same time, it is exciting to have a big model like Fable or Opus 5.5 at hand and to see what you can unlock with it. I have been following math closely, and I keep seeing 18- to 20-year-olds cracking Erdős problems with AI-assisted research. So there is a brighter side too.
Back to math, with a name
With the rise of frontier intelligence, it felt like the right time to get back into math. This time, though, I wanted to teach, to visualise, and to build a cross-platform brand. I called it Matharium.
Matharium is a blend of Math and Aquarium. We are on X, Instagram, Facebook, Threads, YouTube, TikTok, Pinterest and more. I started digging into it around June or July 2026. Finding a username turned out to be one of the hardest parts: X has been around since 2006, so most good handles were taken long ago. I used Claude Code with browser use to hunt through candidates; after a lot of trial and error, and about $25 worth of tokens, it gave me a shortlist with the right one in it. The Math + Aquarium meaning came from Claude too. Pretty nice, right? Cool math in the right place, a gallery or a museum of math.
Shadow ban, Manim and copycats
I opened @matharium on X and started posting math quotes with cool visuals. Then came a shadow ban. It took about three months to get out of it and back on track, more time than I have ever spent growing an account, and I have grown accounts in several other niches. Slowly, Matharium picked up momentum. Around that time, I discovered Manim, the animation library built by the OG himself, 3Blue1Brown. I was surprised I had never heard of it: a math animation library, fully open source, and a perfect fit with Claude. So I started an Instagram account for the visualisations. In those early days I had not found the right brand or colours, and I was posting low-effort illusion videos just to keep the account alive.
With both X and Instagram at their lowest, I decided to rework the branding properly. This was also when content thieves discovered Matharium. I saw copies of our posts all over Facebook, Pinterest and Threads, pulling in thousands of likes. That was the wake-up call to put Matharium on every major platform myself. My coding background helped here: I automated reposting every Instagram video to YouTube, and I set up a personal intern, Grok Bot, to carry Matharium's X posts over to Pinterest. Grok Bot has brought in around 142 Pinterest followers so far, which I think is good given how Pinterest works, and over 1.1M views across all the pins.
The rebrand and the surge
Then came the rebrand: from a cream background to dark chocolate, with a rust accent and a soft teal. I made a lot of videos and learned a lot of math along the way: fractals, Fourier series and other geometric patterns. Drawing shapes with Fourier circles was a big unlock; it grew Matharium on X, and the same idea worked on Instagram in its own format. The major boost came from videos on the functions behind beats in hip-hop, Opium and Phonk. This month, Matharium crossed 40M+ impressions on Instagram and passed 50,000 followers, up from under 2,000 two weeks earlier.
Playing around with Claude has unlocked a lot for us, including infographics for teaching in both video and image form. Matharium is now monetised on X and on the waitlist on Facebook, where it has over 25,000 followers. From getting shadow banned, to two months of grinding to get the account back, to this point: it has been a hell of a ride, and it was worth it.
Who kept the math in me
Through all of it, I have managed to keep the core: the math, the memories, that bench partner, that teacher, and everyone who kept the mathematical spirit alive in me. I am really grateful to all of them. My mom was always happy to see me do well in this field. A part of me already feels happy and blessed imagining how she will feel when I tell her I have started teaching math in some cool new ways. ;)
