mdstill is a document-ingestion tool purpose-built for LLM and RAG workflows. Where generic converters dump messy text, mdstill outputs clean, semantic markdown that preserves tables, headings, and document structure โ€” the things LLMs actually need to understand context.

What you can do with it:

Prepare documents for RAG pipelines (chunk-ready, semantic boundaries preserved) Feed PDFs, Word files, or spreadsheets into ChatGPT, Claude, or Gemini without losing tables Build knowledge bases in Obsidian, Notion, or Logseq from existing document archives Extract structured context for AI agents and embeddings How it's different: Deep-conversion mode runs layout-aware parsing (tables, OCR, multi-column PDFs) โ€” not just text dumping. Markdown output is ~40% more token-efficient than raw text, so your LLM costs drop. REST API available for pipeline automation.

Free tier, no signup required for basic use. Competes with markitdown, Unstructured.io, and LlamaParse โ€” but with a zero-friction web UI.

ReactDemos.com features and specs

  • Focused on React
    ReactDemos.com is specifically dedicated to React, making it a targeted resource for developers looking for React-related demos, examples, and inspiration without having to sift through unrelated content.
  • Hands-on Learning
    The site provides practical, working demonstrations of React components and patterns, allowing developers to see real implementations rather than just reading about theoretical concepts.
  • Free Resource
    ReactDemos.com offers its demo content for free, making it accessible to developers at all levels regardless of budget, including students and hobbyists.
  • Quick Reference
    Developers can use the site as a quick reference to see how specific React features or component patterns are implemented, saving time compared to building prototypes from scratch.
  • Beginner Friendly
    The demo-based approach is particularly helpful for beginners who learn better by seeing working examples rather than reading through extensive documentation or tutorials.

Possible disadvantages of ReactDemos.com

  • Limited Scope
    As a niche demo site, ReactDemos.com may not cover the full breadth of React topics, advanced patterns, or edge cases that a more comprehensive learning platform or official documentation would provide.
  • Low Visibility and Community
    ReactDemos.com is not a widely known or heavily trafficked resource, meaning it may have a smaller community, fewer contributions, and less peer review compared to established platforms like CodeSandbox or StackBlitz.
  • Potentially Outdated Content
    Smaller demo sites can struggle to keep content updated with the latest React versions and best practices, which may lead to demos using deprecated patterns or older syntax.
  • Lack of In-Depth Explanations
    Demo-focused sites often prioritize showing code over explaining the reasoning behind architectural decisions, which can leave learners without a deeper understanding of why certain approaches are used.
  • No Interactive Editing
    Compared to platforms like CodeSandbox or StackBlitz, ReactDemos.com may lack robust in-browser code editing and live preview capabilities, limiting the ability to experiment and modify demos in real time.

Questions & Answers

As answered by people managing ReactDemos.com and mdstill.

What makes your product unique?

mdstill's answer:

mdstill is built specifically for LLM and RAG workflows, not generic file conversion. Drop any of 20+ document formats (PDF, Word, Excel, PowerPoint, EPUB, and more) and get back clean, structure-preserving Markdown that's tuned for ChatGPT, Claude, Gemini context windows and vector-database ingestion. Tables stay intact, headers become linkable anchors, output is ~40% more token-efficient than raw text extraction. Free web tool + REST API โ€” humans and pipelines use the same engine.

Why should a person choose your product over its competitors?

mdstill's answer:

Alternatives fall into two camps: developer libraries that require setup, or enterprise SDKs that require a sales call. mdstill fills the middle: open a browser, drop a file, get Markdown in seconds โ€” and when you need to scale, the same conversion runs through a REST API. 20+ formats in one tool instead of picking a different parser per format. Tables survive the trip (most tools mangle them). Files are deleted immediately after processing. Free tier, no credit card, no signup for basic use.

How would you describe the primary audience of your product?

mdstill's answer:

Two overlapping groups. Developers building AI features โ€” engineers feeding documents into ChatGPT, Claude, or Gemini APIs; teams building RAG pipelines and AI agents who need reliable document ingestion. Knowledge workers and researchers โ€” Obsidian and Notion users importing legacy PDFs, students preparing papers for AI analysis, analysts converting spreadsheets for LLM review. Common thread: anyone who's discovered that pasting raw PDF text into an LLM loses tables and wastes tokens.

What's the story behind your product?

mdstill's answer:

mdstill started from a personal frustration: feeding documents into ChatGPT and Claude meant pasting messy PDF text with broken tables and lost structure, or paying for heavyweight enterprise tools just to preprocess a few files. The fix seemed obvious โ€” Markdown is what LLMs understand best, so the conversion should be a utility anyone can use, not a product you buy. mdstill was built to make high-quality document-to-Markdown preprocessing free and instant for everyone, with an API for teams who need to scale.

Who are some of the biggest customers of your product?

mdstill's answer:

mdstill launched publicly in April 2026 and is in the early-adopter phase. Currently used by individual developers, indie AI-tool builders, and small research teams โ€” customer logos will be added as early adopters opt in to share them.

Which are the primary technologies used for building your product?

mdstill's answer:

Python + FastAPI on the backend, Next.js + TypeScript on the frontend.
