<h2 id="what-is-this">What is this</h2>
<p><em>txtdot</em> is a proxy that requests the page by the given URL,
extracts only useful data including text, links, pictures and tables,
and returns it as an HTML page with a minimalistic design
optimized for text reading.</p>
<p><em>txtdot</em> increases the loading speed and reduces client's bandwidth usage
since no unnecessary code and no scripts are transferred.
Also, you won't see any advertisement (unless it's a static picture that is hard to detect as ads).
There are no trackers too.</p>
<h2 id="how-to-use-it">How to use it</h2>
<p><em>txtdot</em> is an open source software, so everyone can host it on his own server.
The official instance is <a href="https://txt.dc09.ru">txt.dc09.ru</a>,
the list of all instances is <a href="https://github.com/txtdot/instances">here</a>.</p>
<p>On the main page, there's a handy form where you can
specify a URL, choose an engine and a format for parsed data.
On the <code>/get</code> page, "Home" button returns you to <code>/</code>,
"Original page" opens the entered URL in the same window without txtdot proxy.</p>
<p>The latest docs for API endpoints can be found <a href="https://txt.dc09.ru/doc">here</a>.
For handy JSON API, use <code>/api/parse</code> returning an engine result object (see below).
For pure HTML response, use <code>/api/raw-html</code>.
Note that both API and browser endpoints on txt.dc09.ru
are ratelimited to 2 requests per second.</p>
<h2 id="how-it-works">How it works</h2>
<p>This project exists thanks to great Mozilla's
<a href="https://github.com/mozilla/readability">Readability.js</a> library.
The initial idea was to process HTML with it on the server
so the client does not need to download and execute heavy JS,
doesn't need to use an adblock.</p>
<p>Readability performs its work very well in most cases.
But not always. For example, check any StackOverflow page or Google search results.</p>
<p>So <a href="https://github.com/artegoser">artegoser</a> wrote the basis of the code
keeping in mind that we'll extend txtdot with other <em>engines</em>.
For now, engines are functions taking a URL as a parameter,
returning an object that contains extracted HTML and plain text, page title and language.
The object is rendered with ejs template (or, in <code>/api/parse</code>, just sent as JSON).</p>
<p>If an <code>?engine=</code> parameter wasn't passed, but txtdot found
