AI writing assistance for journalists — now rebranded as Prism
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.
A free, AI-powered academic search engine for 240M+ papers across every scientific field
Search 241 million-plus publications from every scientific field using natural-language queries that match meaning rather than exact keywords.
Each indexed paper gets a one-sentence machine-generated TLDR so you can triage results before committing to reading the full text.
An augmented PDF reader that highlights citations, definitions, equations and figures inline, and shows which later papers cited the passage you are reading.
See how a paper was cited, whether citations were influential, and which references shaped the work — useful for literature reviews and citation chasing.
