Claude Scientific Writer—the same AI-powered research and writing engine behind K-Dense Web—is available as a free, open source tool. Whether you're preparing your next manuscript, drafting a grant proposal, or documenting clinical findings, this tool transforms how researchers create publication-ready documents.
The Real Problem with AI Writing Tools
If you've tried using ChatGPT or similar tools for scientific writing, you've probably encountered the same frustrations:
Hallucinated citations. The AI confidently cites papers that don't exist, or misattributes findings to the wrong authors. You spend more time fact-checking than you saved on writing.
Generic outputs. A Nature paper has different conventions than an NIH grant proposal. Most AI tools produce one-size-fits-all text that requires extensive reformatting.
No access to current literature. Your field moves fast. AI models trained on year-old data can't help you contextualize your work against the latest findings.
Disconnected from your data. You have spreadsheets of results and folders of figures, but getting an AI to meaningfully reference your actual experimental data feels impossible.
Claude Scientific Writer was built to solve these problems.
Research First, Then Write
The fundamental difference in our approach: Claude Scientific Writer researches before it writes.
When you ask for a paper on your research topic, the tool first searches current literature using Perplexity Sonar Pro Search. It identifies relevant findings, verifies claims against actual publications, and generates proper citations automatically. The result is text grounded in real, verifiable sources—not AI confabulation.
This matters because scientific credibility depends on accurate attribution. A single fabricated citation can undermine an entire manuscript. By building verification into the writing process itself, we've eliminated one of the biggest risks of AI-assisted writing.
Publication-Ready Outputs Across Domains
The tool produces properly formatted documents for the venues researchers actually submit to:
Scientific papers structured for top journals—Nature, Science, Cell, NeurIPS, ICML—with correct section organization and citation formatting.
Grant proposals meeting the specific requirements of NSF, NIH, DOE, and DARPA, including budget justifications and timeline templates.
Research posters generated as professional LaTeX documents ready for conference presentation.
Literature reviews with systematic organization and comprehensive citation management.
Clinical documentation including case reports, diagnostic summaries, and trial reports following medical documentation standards.
Each output type follows the conventions of its target venue. An NSF proposal reads like an NSF proposal, not like a blog post with section headers added.
Your Data, Integrated
Scientific writing isn't just prose—it's the presentation of results. Claude Scientific Writer understands this.
Point the tool at your data files and figures, and it will reference them meaningfully in the generated text. Describe your Western blot results, cite the statistical significance from your spreadsheet, discuss the trends visible in your graphs. The AI doesn't just acknowledge your data exists; it interprets and presents it in context.
This integration extends to document conversion. PDFs, Word documents, and presentations are automatically converted to formats the AI can understand, so your existing materials become part of the writing context.
Iterative, Not One-Shot
Good scientific writing emerges through revision. The tool supports this natural workflow with features like peer review simulation using a quantitative evaluation framework, context-aware revision suggestions, and the ability to continue editing previous outputs.
Start with a rough draft, refine the methods section, strengthen the discussion of limitations, add a comparison to related work. The AI maintains context across these iterations, understanding what you've written and what still needs work.
All of This—And More—In K-Dense Web
Everything in Claude Scientific Writer is also available in K-Dense Web, our full-featured AI agent platform. K-Dense Web extends these capabilities with deeper research integration, enhanced figure generation, persistent project sessions, and enterprise features for research teams.
If the open source tool fits your needs, use it freely. If you need more power or want a fully managed experience, K-Dense Web builds on the same foundation with additional capabilities.
Free and Open Source
Claude Scientific Writer is released under the MIT license. Use it, modify it, build on it. We believe powerful research tools should be accessible to scientists everywhere, regardless of institutional resources.
The code is available on GitHub at github.com/K-Dense-AI/claude-scientific-writer. Installation takes minutes via pip or as a Claude Code plugin.
Join the Community
We've built a Slack community where researchers share tips, ask questions, and help each other get the most from these tools. Whether you're troubleshooting an installation issue or sharing a workflow that worked well for your lab, we'd love to have you.
