To my immunologist and biomedicine colleagues —at the very least, for making scientific illustrations that are spot on... from your own PDFs or summaries of the literature, I've yet to see anything better.
DeepWriter is not an LLM itself- it sits on top of other LLMs and does the agentic work (right now it uses Gemini 2.5, but can use Gemini 3 or other LLMs at some point, I understand).
For reports and work I do, it's better than any of the "AI Scientists" I've seen so far. And the great thing is... as other LLMs improve, the DeepWriter overlay improves.
And this is just for science. I've used it for many other things as well. It's fantastic.
If you are a VC or seed fund, I'd seriously look at these guys.
Public service announcement —I hold no equity or monetary-compensated position with DeepWriter, but I have been advising them on how to nudge it toward better-written reports. The illustration work they did shocked me at how accurate it can be. I want them to succeed because I can already see how essential what they have is to my work. The illustration below is from a prompt I asked them to generate about tertiary lymphoid structures. I've used their illustrations in several of my recent biomedical talks.
We asked DeepWriter about tertiary lymphoid structures for cancer therapy.
It returned a full report with illustrations and PubMed citations.
The report had a clear evidence-to-conclusion narrative.
