Free podcast tools
Nine things podcasters check or fix before publishing, done in the browser. Your files stay on your computer, and you never need an account.
The AI models for speaker detection and transcription run on your machine too.
Before the edit
Line up the cameras and catch file problems while they’re still easy to fix.
Fix the audio
Catch the two things listeners notice most: dead air and wrong volume.

Silence remover
Find long pauses, tighten them to a natural beat or cut them out, then download the audio or an EDL for your editor.

Loudness checker
Measure integrated LUFS and true peak against what Apple Podcasts, Spotify and YouTube expect.

Nothing leaves your computer
These tools do their work with your browser’s own audio and video APIs. We never see the file, and there is no upload to wait for.

When the whole episode needs cutting
The free tools handle one job each. WizCut itself edits multicam video podcasts: it listens to who is talking and switches cameras for you.
