Academic proofreading, plagiarism checking and AI-powered writing tools in one place
A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
A private, offline notebook that turns your own sources into reports, decks and briefings
Install a normal desktop app on Windows, macOS or Linux and run it with no account. With a local model you can pull the network cable and keep querying your indexed sources, since nothing is sent to a vendor.
Choose a bundled local Qwen or Gemma model at first launch, or paste a key for OpenAI, Anthropic or any OpenAI-compatible endpoint. The model is a setting rather than a fixed vendor choice.
Turn one set of sources into slide decks, reports, briefing notes, podcasts, mind maps, flashcards, quizzes, Markdown, Word, PDF, HTML and spreadsheet outputs — generated and stored locally.
Optional plugins pull research from Google Search, Reddit, YouTube, Instagram, TikTok, Google Maps, Amazon, Walmart, Indeed and the open web, and anyone can register their own MCP server.
