How it works
- Make your cards. Type your notes below. Each card is one calculator screen.
- Download one file. You get a small
.pyprogram with your notes inside. No coding needed. - Send it to your calculator. Use TI Connect CE, the free Texas Instruments program, and the USB cable. See how.
- Open it. On the calculator, start the Python App, choose your program, and press ENTER to flip through your cards.
CONFIDENCE INTERVAL estimate +- margin of error

Your program's source code
Good to know
- Check your class rules. Use note cards for studying and for tests where calculator notes are allowed. Many exams require calculator memory to be cleared.
- Size limit. A program can be up to 6,000 bytes here. The TI Python App holds 50 KB or 100 programs in total, so archive programs you are not using.
- Plain characters only. The calculator shows standard keyboard characters. Curly quotes and long dashes are converted; anything else becomes "?".
- On the calculator. Press ENTER for the next card, 1 to go back, 2 for the menu, and 0 to quit.
- Not individually tested. Each program is built from one fixed template around your text. Hidden Word Scanner does not see, store, or review what you type.
- Privacy. Downloads and preview starts are counted in total only. Your notes, title, and program name are never sent.
