Karla (now Prism)
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.
Turn raw source material into articles
Paste notes, documents, transcripts or press material and let the AI reshape it into a coherent article draft.
Structured writing workflow
An editor built around the way newsrooms work, so structure and flow matter as much as speed of drafting.
LLM-powered drafting
The engine underneath was built as a large-language-model-based writing assistant rather than a simple summariser or rewriter.
Now evolved into the Prism platform
The project has evolved into Prism, a platform for defining and executing complex AI processes, with journalism features maintained at Newsrun.ai.
Pontos fortes e vantagens
+Purpose-built for newsroom and editorial workflows
+LLM-based drafting that goes beyond simple summarisation
+Turns scattered source material into a structured starting draft
+
Technology lives on and is actively developed under the Prism brand
Limitações
–The Karla name no longer exists — the product is now branded Prism, which can confuse people looking for the original tool
–Journalism-specific workflow features have been split off to a separate product, Newsrun.ai
–New target audience (developers and process designers) means some original newsroom-oriented features may not map to every user's needs
