So you finally got ChatGPT to know you.
Your projects, your tone, what you're actually working on. Months of conversation.

Then you switched to Claude.
It knows nothing about you. Or your projects. Or your style. Don't you wish what you tell one app, every other app already knew?

We built Context Hub while building Rehearsal AI.
Gradeless AI is a frontier application lab born inside the Integral Education Society — the 60+ year Indian education trust that operates the Jaipuria Institute of Management and Seth M.R. Jaipuria Schools.
We're best known for Rehearsal AI: a mobile-first microlearning platform that delivers 15-minute capsule courses on management, business, and AI concepts — paired with AI voice-agent mock interviews for MBA, FAANG, and consulting candidates. Building Rehearsal stretched our agentic-AI orchestration engineering hard — multi-agent routing, real-time evaluation, persistent memory across learning sessions — and forced us to solve cross-tool memory ourselves.
Context Hub is the first of those internal primitives we're open-sourcing. More agentic-AI building blocks are coming through 2026.
