## Runway strengths

- Combines video, image and audio generation and editing in one workspace
- Offers Runway's own Gen-4.5 plus third-party models such as Seedance 2.0
- Creative Agent builds videos from a conversation
- Runway Dev API with Node and Python SDKs
- Free plan with 125 credits that do not expire

## Runway limitations

- Credit-based pricing: a 5-second Gen-4.5 clip costs 60 credits, so the 625 credits on Standard cover about 10 such clips
- Standard and Pro credits do not roll over at the end of the month
- Some App Store reviewers complain about the cost of failed or unusable generations
- 4K upscaling is unlimited only on Pro and Max

## Voice AI Checker strengths

- Usable without an account, with one free check per day
- Uses a named third-party detection model (Modulate Velma-2) and discloses it
- Clear plans with a $4.99 no-subscription option
- Honest about limits: results are labelled as a signal, not proof
- Failed checks return the reserved credit automatically

## Voice AI Checker limitations

- Free tier is very small: 1 check per day (15 seconds) without sign-in
- No accuracy figures; the only evidence is a four-clip case study where both human clips returned "unclear"
- The owner or legal entity is not named; support is a personal Gmail address
- Clips capped at 30 seconds, and reliability drops with music, noise or multiple speakers
- Web only, with no public API
