The trade-offs
Strengths and Limitations
Async
Strengths
- Records, cleans up, edits and publishes in one browser tool
- Editing by chat instruction rather than by timeline
- Turns one recording into clips, captions and a transcript
- Free plan available, and a developer voice API alongside the studio
Limitations
- The public pricing page names the plans but leaves the amounts blank, so a price has to be looked up in the help centre or in the app
- Metered in AI credits, so heavy months cost more regardless of seat count
- Free plan's AI credits and transcription are lifetime allowances, not monthly ones
- The vendor cautions that AI edits need reviewing
Supertone Clear
Strengths
- Real-time, so it works live as well as in post
- Perpetual licence rather than a subscription
- Three controls, with little to learn
Limitations
- Dialogue cleanup only, no editing or mastering
- No ongoing free tier, the trial inserts noise every 60 seconds
- A plugin, so it needs a DAW or another host
