Show HN: DocEditor – LLM Open Source Document Editor (Streamlit Live Demo)

I'm excited to introduce DocEditor, an AI-powered document editor designed for smart editing and real-time feedback. It’s open source, completely free, and doesn’t require a login. You can try it live at: https://doc-editor.streamlit.app https://doc-editor.streamlit.app (hosted on Streamlit Cloud). You can also access the code on my github repo at: https://github.com/clchinkc/streamlit-editor/ https://github.com/clchinkc/streamlit-editor/ What DocEditor Offers: - Intelligent Editing & Feedback: Uses DSPy’s signature definition for context-aware suggestions. - Handles Long Documents: Leverages LangChain to process and manage extensive content seamlessly. - Structural Refinements: Goes beyond grammar checks to improve clarity, flow, and organization. Recent Enhancements: - Added Ollama/OpenRouter support (details on GitHub). - Redesigned Summary Dashboard based on user feedback. - Introduced a manual summarization toggle to reduce token usage. - Mermaid-based summary visualization for clearer insights. Looking for Feedback On: 1. Document Compatibility: How well does DocEditor handle different file formats you work with? 2. Domain Specialization: Should I focus on a specific area like legal, academic, or technical writing, or keep it general? 3. Tech Stack Migration: Streamlit struggles with complex editing—would moving to a full framework like NextJS be a better option? Try it out and let me know what you think.
