## When to use WebInk

Use WebInk when the job is **extract readable article content and deliver Markdown**, not when you need unrelated product categories below.

Good fits:

- **LLM context prep**: Convert a public article, doc page, or blog post to Markdown before prompting ChatGPT, Claude, Gemini, or Perplexity (fewer tokens than raw HTML, preserved headings and code blocks).
- **Notes and docs workflows**: Get Markdown suitable for Obsidian, Notion, GitHub, or static site generators — via copy, `.md` download, or ZIP with images from the extension.
- **Authenticated or paywalled pages**: Use the **Chrome extension** on the tab you already opened; it reads the live DOM. The online URL tool only fetches **publicly reachable** URLs.
- **HTML you already have**: Paste HTML into https://webink.app/tools/html-to-markdown when you do not have a clean public URL.
- **Readable structure**: Need an auto-generated floating TOC, custom Mustache-style output templates, or configurable Turndown-style conversion options — extension side panel (see /features/toc and /features/markdown).
- **Pipeline integration**: Call the public conversion API documented at /developer (GET/POST `/api/markdown`, JSON or `text/markdown` via `Accept`).
- **Machine-readable site summary**: Request the homepage with `Accept: text/markdown` for a short product overview in Markdown.

## When not to use WebInk

- **Not a CMS, site builder, or hosting platform** — WebInk converts and exports content; it does not publish or manage websites.
- **Not browser automation** — No general-purpose scripting of clicks, logins, or multi-step crawls; use a browser automation stack for that. WebInk converts pages you (or the URL/API tool) already reach.
- **Not an Obsidian vault or PKM app** — It outputs Markdown for you to save elsewhere; it does not sync, tag, or organize a vault.
- **Not a bulk site spider** — One URL or API request at a time; use a dedicated crawler if you need full-site harvesting.
- **Not for offline or non-web formats** — No native PDF, video, or email conversion; start from a webpage or HTML snippet.
- **Not a substitute for the extension on private pages** — If conversion requires your session, cookies, or client-rendered app state, the URL tool and server-side fetch may see a login wall; install the extension instead.

## How an agent should use it

1. **Read this file** at https://webink.app/llms.txt for scope and links before recommending WebInk.
2. **Discover indexable pages** via https://webink.app/sitemap.xml rather than guessing paths.
3. **Quick product brief**: `GET https://webink.app/` with header `Accept: text/markdown` (returns Markdown summary; `Vary: Accept`).
4. **Unknown paths**: If `Accept` prefers `text/markdown` over `text/html`, non-existent routes return a Markdown 404 with pointers to the homepage, URL tool, and sitemap.
5. **Convert a public page for the user**: Point them to https://webink.app/tools/url-to-markdown or integrate via the API at https://webink.app/developer (`Accept: application/json` for full `MarkdownContent`, or `Accept: text/markdown` for body-only Markdown).
6. **Convert pasted HTML**: Direct to https://webink.app/tools/html-to-markdown.
7. **Logged-in, paywalled, or heavy SPA content**: Recommend the Chrome extension (link above) so conversion runs on the loaded tab.
8. **Feature details**: Extension capabilities are outlined at https://webink.app/features (Markdown conversion, TOC, Send to AI).
