I can see — it's asking to factor x² − 5x + 6. I'll add this as a worked example under chapter 1?
हाँ
ठीक है — example added with the full solution. live now.
That's tara, the assistant for a math teacher. Same model, same code, runs locally — and works in Hindi or English.
01
Each person gets their own agent
Their name, their personality, their tools, their memory. Mom's agent isn't your agent isn't your friend's agent. No shared context. No data mixing.
02
Text it like a friend
Plain language. Voice notes. Photos. Hindi or English. The agent listens, asks if it's unsure, and does the work — without making you learn a new app.
03
It just works
Websites update. Chapters get written. Questions get answered. The agent remembers what you said last week. You see the result in WhatsApp.
Voice notes
Hold the mic, speak in Hindi or English. Faster than typing on a phone keyboard.
Web search
The agent can look things up for you — a definition, a reference, a current event.
Memory
Each agent remembers their person's preferences and past conversations across sessions.
Hindi · English
Type in whatever script you prefer. The agent responds in the same one.
Local, private
The AI runs on a machine you control. Your conversations don't go to a cloud provider.

Tara's site
Tara is a math teacher. She doesn't write HTML. When she wants to add a chapter, fix a typo, or change the colour, she just messages her assistant on WhatsApp. The site updates in seconds.
Every change she makes lands at tara.e51.org — built by the same agent you saw in the chat above.
Why WhatsApp
600 million people in India use WhatsApp. Almost none of them have downloaded ChatGPT. The friction isn't the model — it's everything around it: the app store, the email signup, the credit card, the new vocabulary. Take all that away and AI becomes something your mom uses the same way she uses any other contact.
