Drop in a clip with speech and it is transcribed on your own device — nothing is uploaded. Fix any word in the editor, restyle the cues, then export clean SRT/VTT or a video with the subtitles burned in.

Turn an interview, a lecture or a voice memo into a clean text transcript that runs entirely in your browser. Copy the result or download a .txt to drop into your notes or your script.

Convert subtitles between SRT, VTT and plain text, shift the timing to correct an offset, and rescale time when the frame rate changes — all locally, in seconds.

A fast in-browser toolkit for everyday jobs: trim the dead ends, extract the audio to MP3, turn a moment into a GIF or grab a still. Runs on ffmpeg.wasm, so your files never leave the device.

Set a start and an end and download just the part you need. A stream copy keeps the original quality and finishes in seconds; the cut rounds to the nearest keyframe. Runs on ffmpeg.wasm, and nothing is uploaded.

Pull the soundtrack out of a video for podcasts, transcripts or music — MP3 where the browser supports it, otherwise M4A (AAC). Runs on your device with ffmpeg.wasm; the file is never uploaded.

Make a shareable GIF from any clip, with a two-pass palette for a clean result. Capped at 15 seconds to keep the file size sane. Runs on ffmpeg.wasm, and nothing leaves your device.

Catch the perfect frame from any video at full resolution and save it as PNG or JPG — good for thumbnails and press stills. Everything happens on your device, and nothing is uploaded.

A screen recorder with no install and no watermark, with optional microphone narration. Record a tab, a window or any display, then download the clip. Nothing is uploaded.

Record straight from your microphone with a live level meter, listen back, and download the result. No install, no sign-up, and nothing leaves your device.

Make sure your camera and microphone work before a call or a recording — live preview, device selection and a real-time microphone level meter. Nothing is recorded or uploaded.

Take a photo from your webcam with an optional three-second countdown and mirror mode, then download it. A plain, direct camera; nothing is recorded or uploaded.

A rock-steady WebAudio metronome with tap tempo, a custom time signature and an accented first beat of the bar — accurate timing for practice and for tracking.

Point the microphone at any instrument, or sing a note, and get a real-time pitch and cents readout with a clear, sharp indicator. Good for guitar, strings, wind and voice.

Sing the lowest and highest notes you are comfortable with and the tool maps your range, names the notes and suggests a voice type — a quick way to pick keys that suit you.

Sharpen your relative pitch with interval drills, instant right-or-wrong feedback and a streak counter that keeps you focused. A few minutes a day is enough to hear the difference.

Generate a clean test tone at any frequency, choose the waveform and set the level — for checking monitors, headphones, room response or a signal chain.

A full-screen teleprompter that scrolls itself, follows your voice, or mirrors for a beam-splitter rig — and can record your webcam at the same time, so you read straight into the lens.

Paste a script and get an accurate estimate of how long it takes to read aloud at your chosen pace — alongside a word and character count — so your video comes out the length you planned.
