What GhostCalc makes

GhostCalc takes the familiar TI-84 Plus form factor and adds a hidden AI layer for study workflows: asking questions, checking steps, reading notes, and moving calculator programs faster. The goal is practical hardware that feels finished, not a loose prototype.

Hardware first

Each unit is assembled, flashed, and bench-tested before it ships.

Calculator native

The normal calculator experience stays at the center of the product.

Real support

Setup, firmware notes, and order questions go through Discord or email.
