Builds the whole ad, not a clip
Brief it once and the Solid Agent writes the concept, picks the takes, writes the script, adds the voice and assembles a finished, editable ad.
An honest, side-by-side comparison of Solid and Kapwing on features, pricing and fit.
Quick comparison
Solid vs Kapwing: For performance video ads, Solid is the stronger choice. Kapwing is a friendly browser editor with strong subtitle and translation tools, but you still edit every ad yourself. The Solid Agent builds the ads for you from your own footage in a chat, follows your Brand Hub and returns every hook, format and language variant, all editable in Solid’s AI video editor. Pick Kapwing for quick edits, subtitles and translations of single videos.

Solid is not only a generator. It cuts your real footage into ads and generates what is missing.
Real footage first
Generation built in
The Solid Agent
Other tools generate assets. The Solid Agent runs the production end to end, on your own footage and brand.
Brief it once and the Solid Agent writes the concept, picks the takes, writes the script, adds the voice and assembles a finished, editable ad.
It searches every scene, transcript and person in your library and cuts your best takes in order. Generation only fills the gaps.
It reads your Brand Hub, video guidelines and House Rules before every script, and remembers what you teach it.
It proposes concepts and recommends one, so you steer the idea before anything is rendered.
Rewrite a line, add hooks, swap a clip or restyle captions by typing. Every hook, body and CTA combination stays editable.
It summarizes reviewer comments, works the feedback in and translates approved ads for every market in one request.
