Tools that measure or visualize what's already in front of you. Word Counter tallies words, characters and estimated reading time as you type or paste, Text Summarizer condenses a long article down to its key sentences, and Audio Oscilloscope draws a live waveform from your microphone or an audio file.
The analysis runs entirely on your device — pasted text and microphone audio are processed locally and never sent anywhere for scoring or storage. Useful for writers checking an essay against a word-count limit, students skimming a long PDF's argument, and musicians watching signal levels in real time.
