Research & Writing Tools
Free, practical calculators for research and document work — convert words to pages, estimate reading and writing time, score readability, budget AI token costs, and measure how tightly a summary compresses its source. Everything runs in your browser; nothing is stored.
Word Count to Page Count Converter
Turn a word count into an estimated page count (or the reverse) for a standard 12pt page, switching between single and double spacing.
Reading Time Estimator
See how long a text takes to read silently and to read aloud, from its word count and an adjustable words-per-minute speed.
Flesch Readability Scorer
Score a passage with the Flesch Reading Ease and Flesch–Kincaid grade formulas, with the word, sentence, and syllable counts behind them.
AI Token & Cost Estimator
Convert prompt and response word counts into estimated tokens and dollars, using separate input and output rates, for one request or a batch.
Writing Time Planner
Estimate how long a draft will take from a target word count and a realistic pace, spread across your writing hours per day.
Summary Compression Ratio Calculator
Compare a summary with its source to see the compression ratio, the reduction, and how many times shorter the summary is.
Document Planning Reference
Five typical document lengths laid out against page count, reading time, and writing time, plus three sample passages showing what a readability score actually measures — every figure computed live from the calculators above.
