How it works

From a photo to the winnable marks.

CheckMate turns any marked paper into an honest, plain-language diagnosis — with the smallest fixes that win the most marks back.

1 · Capture on your device

Open the camera in the browser (with permission) or upload photos or a PDF. Every page is downscaled and compressed on your device — nothing heavy is ever sent up.

2 · Read, mark, double-check

Each answer is read and marked. A second independent pass audits the marking and downgrades anything it is unsure about, so you never get false confidence.

3 · The winnable-marks report

You get the recoverable-marks number, the micro-gaps behind lost marks, a "silly mistakes" log, and readiness bands for JEE / GUJCET / boards.

Honest by design

Evidence tiers (Full / Grounded / Indicative) tell you how sure the read is. We never present an unsure read as a confident one.

Built for real papers

Handles teacher-marked papers, standard answer keys, or just the student's answers — and multi-page tests in one go.

Private & compliant

Student names are aliased before any AI sees the work, scans are encrypted at rest, and everything follows India's DPDP Act.

Start with one paper.

In about a minute you'll see exactly which marks were within reach — and how to get them back.
