Wisio

Wisio is a writing tool built specifically for researchers drafting scientific manuscripts, aimed particularly at people writing in English as a second language. It combines a manuscript editor with an AI advisor that gives project-scoped feedback, rather than acting as a generic grammar checker. A feature called Precision Mode lets a user index up to five of their own reference PDFs so that AI suggestions are grounded in those specific sources instead of the model's general knowledge, and a built-in search over PubMed and Crossref lets users find and insert APA-style citations without leaving the editor. Other features include Scientify, which turns rough notes or non-English drafts into academic English, grammar correction tuned to academic conventions like passive voice and formal register, and an AI Feedback pass that flags claims in the draft that aren't backed by a citation. Wisio says it is used by more than 35,000 researchers across 500-plus universities. The product offers a 7-day free trial with full access, after which a Pro plan costs $12 a month billed yearly or $24 month-to-month, plus a Teams plan with custom seat-based pricing. It does not list an API or third-party integrations, so it is best suited to individual manuscript writing rather than being wired into a larger research workflow.
