Common use cases

GPA planning

Model “what if” grades to understand which assignments move your final grade the most.

Focused study sessions

Use Pomodoro intervals to stay on task, then log sessions to build momentum week by week.

Unit and formula checks

Convert units before calculating and write the formula first. This prevents most avoidable errors in science and engineering problems.

Essay editing

Word count, reading time, and keyword frequency help you tighten writing and reduce repetition.

Privacy & saving your progress

Some tools in this category can save your entries locally (for example, tasks and study sessions) using localStorage. This data stays in your browser and can be cleared at any time using the tool’s reset button.

Study workflow tip

Keep a separate row per class and include credits to get a weighted GPA that matches most transcripts.
