Pros and cons

Riff

Pros

  • Free, with no account, subscription or API key
  • Generation runs on-device with Gemini Nano, so text is not sent to a server
  • Covers replies, DMs, posts and X threads in one side panel
  • Never presses send, which keeps the user in control
  • Dials for tone, pitch and length, plus a Fresh score to avoid repetitive openings

Cons

  • Requires desktop Chrome 138 or newer and a one-time Gemini Nano download
  • Output quality is limited by the small on-device model
  • Chrome only; no Firefox, Safari or mobile support
  • Very new, with few reviews on the Chrome Web Store

Runway

Pros

  • 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
  • Native iOS and Android apps

Cons

  • 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
