Karla was an AI-assisted text editor built for journalists that turned raw source material — notes, documents, transcripts and press releases — into structured, publishable articles. The product has since been rebranded as Prism, which now focuses on building a protocol and platform to define and execute complex processes with AI; the journalism tooling lives on in the separate Newsrun.ai service.

Paste notes, documents, transcripts or press material and let the AI reshape it into a coherent article draft.
An editor built around the way newsrooms work, so structure and flow matter as much as speed of drafting.
The engine underneath was built as a large-language-model-based writing assistant rather than a simple summariser or rewriter.
The project has evolved into Prism, a platform for defining and executing complex AI processes, with journalism features maintained at Newsrun.ai.
