Claude Scientific Writer

Claude Scientific Writer is an open source deep research and writing tool that produces publication ready scientific papers, reports, posters, grant proposals, literature reviews and other academic documents. It researches before it writes, so each claim is meant to rest on real, verifiable sources, and it combines real time literature lookup, paper detection, citation verification, document conversion and AI generated diagrams in one workflow. It suits researchers, lab members and technical writers who want a drafting agent that works from their own data and figures. It runs three ways: as a Claude Code plugin, which is the recommended route, as a Python package installed from PyPI with an asynchronous paper generation API, or as a native command line tool with controls for permissions, budget, token usage and effort level. Research lookup and web search run through Parallel Search and Extract, optional image generation for schematics, figures, slides and infographics runs through OpenRouter, and PDF output relies on a local LaTeX distribution. Optional extras add cohort statistics and survival analysis, plus Word, PowerPoint and Excel helpers. The tool is free and released under the MIT license. Running it requires an Anthropic API key and Parallel credentials, and an OpenRouter key for image generation, so real costs come from those third party services at their own rates. The project comes from a company that also sells a hosted AI research agent, with a free pay as you go Personal tier, Plus at $199 per month or $1,799 per year, Team at $499 per month or $4,499 per year, and custom Enterprise pricing. Those plans are separate from this free open source writer.
