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.
