The TI-Nspire series uses a different operating system compared to Texas Instruments' other calculators. In 2019, the TI-Nspire CX II was added, with a boost in clock speed and changes to the existing operating system. TI got rid of the removable keypad with this generation and therefore, the TI-84 compatibility mode. The updates included improvements to the original's keyboard layout, an addition of a rechargeable lithium-ion battery, 3D graphing capabilities and reduced form factor. In 2011, Texas Instruments released the CX line of their TI-Nspire calculators which effectively replaced the previous generation. The original TI-Nspire was developed out of the TI PLT SHH1 prototype calculator (which itself was derived from the Casio ClassPad 300), the TI-92 series of calculators released in 1995, and the TI-89 series of calculators released in 1998.

The calculators feature a non- QWERTY keyboard and a different key-by-key layout than Texas Instruments's previous flagship calculators such as the TI-89 series.

The TI-Nspire is a graphing calculator line made by Texas Instruments, with the first version released in July 2007.
