What the framework does in deployment.
ClassGrade is BlueberryML's framework for sovereign partner deployments — exam authoring and grading, outcome-based reporting, school and student dashboards, voice-first speaking and reading assessment, and a student app, all running on the partner's infrastructure under the partner's brand. This site is the capability surface.
The capabilities below ship as ClassGrade — used directly, or as a custom-branded build. Chrysalis AI is one such build: BlueberryML's framework in production across 300,000+ students and 1,000+ schools in India, through our partner EZ Vidya — a deployment successful enough to carry the partner into the B2C space. Every capability below runs there today.
The closed core, the open tools.
The manifold stays sealed; the tools put it to work — author against it, grade against it, report against it. The same tools run in production today as Chrysalis AI.
See what each skill builds on, and what comes next.
Every subject builds on a published open standard — a public seed anyone can read. For English that’s CEFR; Maths and Science build on their own, TIMSS and NGSS. On top of the seed sits a proprietary layer, read from data and kept private to whoever owns it — here, Blueberry. This demo runs in English: switch the lens and watch the shared CEFR seed and the private read diverge.
The system retrieves the exact skills on either side of this point, then writes them up. The wording is generated; the skills it’s built on are retrieved, not invented — read straight from the model underneath.

Interested in deploying this? Start at the partnership page.
ClassGrade does not have a sales motion. The partnership page on blueberryml.com describes what partners bring, what the framework provides, and how the data architecture works. Serious operators evaluating the pattern start there.
Each deployment is partner-led and partner-branded. The framework is the substrate; the surface the end-customer sees is the partner's.
