A manuscript editor that
catches errors early
We make it possible to apply large language models safely and transparently in scientific publishing. Our AI understands your manuscript in full context — including cited references and domain language — to provide precise, verifiable assistance that makes research writing faster, clearer, and more accountable.

Write your manuscript with AI assistance
More than a manuscript editor—your complete research workspace
Manuscript, notes, measurements, and references—all in one place. Track your experimental data alongside your writing. Control who can make direct edits and who must use track changes. Link measurements from your research notes directly into manuscript text. Manage collaboration permissions at the workspace level. Everything syncs automatically.
A reference manager that actually works
Find papers directly inside First Author with our search engine that prioritizes relevant results—then cite them instantly. No context switching. No broken links.
Survival trade-offs in plant roots during colonization by closely related beneficial and pathogenic fungi
The sessile nature of plants forced them to evolve mechanisms to prioritize their responses to simultaneous stresses, including colonization by microbes or nutrient starvation. Here, we compare the genomes o...
See exactly who changed what, when
Every edit is attributed. Comments thread directly on the text. Suggest changes that authors can accept or reject. Perfect for reviewer feedback, co-author revisions, and PI comments.
Our findings indicate demonstrate that the novel pathway plays a critical role in cellular response.
"Demonstrate" is stronger here. Can we add a reference to support this claim?
Full control over collaboration
Share links with external collaborators. Decide who can edit directly and who must use track changes.
Enforce track changes
All edits from this link will be tracked
Values that update themselves
Store experimental measurements in your research notes. Reference them in your manuscript. When the analysis changes, every citation updates automatically—no copy-paste errors.

Two AI assistants designed to catch manuscript errors
Pro and Max plans include Helion and Aureon—specialized AI assistants that review your manuscript at two levels. Helion catches surface issues like typos, grammar, and spelling in real-time. Aureon goes deeper, analyzing structure, logical consistency, and the accuracy of scientific claims. Together, they help ensure your work is polished before submission.
