Free voice and text tools
Thirty-two small tools for dictating, transcribing, testing your audio, converting files, measuring, counting and cleaning up text. Each one opens in this tab and runs on your own machine — no account, nothing to install, nothing that expires. Anything you paste stays inside the page, and so does any audio file you drop in. Two kinds of tool work differently, and each page says so: the live speech-to-text tools listen through your browser's own speech engine, and the audio-to-text converters download an open speech model once, then transcribe on your device.
Speech and dictation
Talk instead of typing, transcribe a recording, find out how fast you actually speak, and work out how long a script will run. Speech to Text and the Voice Typing Test listen through your browser's speech engine; the audio-to-text converters run the open Whisper model on your own device; the calculators are plain arithmetic and hear nothing.

Talk, get text, copy it out. No signup and no file upload.
Open toolVoice Typing Test

Open toolAudio to Text
Transcribe a recording with Whisper on your own device. Export TXT, SRT or VTT.

Transcribe an MP3 on your device, with timestamps and SRT export.
Open toolMP4 to Text
Pull the speech out of a video file and transcribe it locally.

Speech to text in your language
The same Speech to Text tool, opened with another language already selected:
Audio and hardware checks
Check that your microphone works, how loud the room is and whether both speakers are wired the way you think; convert, trim and join recordings; find your pitch and vocal range. Everything runs in the tab: the sound test generates its tones and never asks for your microphone, the live microphone tools record nothing, and files you open are never uploaded.
Microphone Test
Live level meter, device picker and instant playback. Nothing leaves the tab.
Open toolSound Test
Left/right, stereo, phase and a 20Hz-20kHz sweep. No microphone needed.
Open toolDecibel Meter
Live estimated dB, average and peak from your mic, with calibration. Nothing is recorded.
Open toolAudio Trimmer
Cut a clip out of a recording on a real waveform. The file never leaves your tab.
Open toolM4A to MP3
Voice memos and M4A audio to MP3, converted in the tab. Batch supported.
Open toolWAV to MP3
Shrink WAV recordings to MP3 at the bitrate you choose, locally.
Open toolWEBM to MP3
Turn WEBM recordings into MP3 (audio track only), in the tab.

Open toolVocal Range Test
Sing low and high to find your range and likely voice type.
Open toolPitch Detector
Live note, frequency and cents from your mic, for voice or instrument.
Open tool
Speed tests
Timed tests for how fast you type and what the number means next to everyone else's. The clock starts on your first keystroke and runs in the page — there is no leaderboard to sign up for.
Text cleanup
Paste something messy and get readable text back. Built for transcripts, subtitle files, AI output and anything that arrived carrying stray line breaks, smart quotes or timestamps.
AI Text Cleaner
Clean AI output and see every invisible character it was carrying.

Word count to page count for your real font, spacing and margins.

Why these are free
They are the browser-sized version of what the VoiceSnap Pro desktop app does system-wide. Nothing here is a trial, nothing expires, and nothing asks for a card.
A slice of the desktop app
VoiceSnap Pro is a Mac and Windows app: hold one keyboard shortcut, speak, and punctuated text appears in whatever field your cursor is already in. Each tool here does one piece of that job inside a single browser tab, so you can find out whether dictating actually suits the way you work before you commit to anything.
They run on your device
Every tool on this page is client-side JavaScript. The text you paste and the files you open are processed in the page and never sent anywhere, so there is no upload to sit through and no copy of your audio or transcript parked on a server. We could not read it if we wanted to — it never reaches us. Two kinds of tool deserve a plain note. The live speech-to-text pages, in every language, and the Voice Typing Test hand your microphone audio to your browser's own speech service, which in Chrome means Google. The audio-to-text converters download the open Whisper speech model from Hugging Face the first time you use them; after that the transcription happens on your device and the audio itself is never uploaded.
Free here, and free to start there
These tools stay free and unmetered, with no account. The desktop app is a free download too: every account starts with a free allowance and every feature switched on, no card needed, so you can try the real thing on your own work before deciding whether Pro is worth it.
VoiceSnap Pro is free to start on macOS and Windows.
Download freeWhat the desktop app does that a browser can't
A web page can only write into itself. This is the honest gap between the tools above and VoiceSnap Pro running on your Mac or PC.
It types into every app, not just this page
A browser tool can only put text into its own text box. You still have to select it, copy it, switch windows and paste it where it was actually going. VoiceSnap Pro writes straight into the field the cursor is already in — a reply in your email client, a Slack thread, a Word document, a Notion page, a comment box, a code editor, a search field. There is no copy step and no intermediate window.
A global shortcut that works while another app has focus
The shortcut is registered with the operating system, not with a web page, so it fires while you are inside a spreadsheet or a design tool. Hold it, speak, release. You never tab away from what you are doing, and you never go hunting for the tab you left this site open in.
Custom vocabulary that remembers your words
Add the names, product codes, acronyms and jargon you use every day and they come out spelled correctly every time, instead of being guessed at phonetically. A browser tool has no memory of your last session, let alone of how your colleague spells her surname or what your internal project is called.
Voice notes that sync, and remind you
Keep optional dictation history on your computer when you want a text copy, or save an idea as a voice note in your account: tag it, file it in a folder, lock it, rework it with AI actions, or have it remind you tomorrow at nine. A browser tool keeps its text only for as long as that tool's own storage allows.
No tab that has to stay open
VoiceSnap Pro runs in the background and is ready the instant you hold the shortcut. Nothing to keep pinned, nothing to reload after your laptop sleeps, and no microphone permission prompt each time a new tab asks for one.
The desktop app punctuates as it transcribes and uses your personal vocabulary before pasting the text where your cursor is. It also gives you a shortcut to paste your last dictation again, and a pop-up to find the ones before it.
The desktop app is the next step
VoiceSnap Pro is free to start on macOS and Windows: 20 minutes of transcription, 50 AI actions and up to 20 notes, once per account, with every feature and no card. After that, Pro is $18 a month or $108 a year.
