SuperDocs is an AI document editing platform. The AI edits inside the document itself instead of regenerating it in a chat window, so it changes the section you asked for and leaves the rest of the document and its formatting intact.
There are three ways to use it: a full web editor at use.superdocs.app, a REST API, and an MCP server with 38 tools and 4 prompts for AI clients such as Claude Code, Cursor, Windsurf and VS Code. The AI model is included, so there is no separate model key to manage and no separate token bill.
Documents import from .docx, PDF, HTML, Markdown, RTF and plain text, and export to .docx, PDF, HTML, Markdown and plain text. Tables, fonts, colours, lists, indentation, headers and footers, footnotes, citations and tracked changes survive both the edit and the round trip.
Every AI change can be reviewed as a red and green diff, approved or denied individually, and reverted per message with full change history. Several documents can be open and edited in a single conversation, and there is a durable file library across sessions.
Other capabilities include semantic search and summarising, a template and style-guide library, image generation and editing, diagrams, hand-drawn canvas, LaTeX equations, automatic tables of contents, and editing in more than 16 languages.
The free plan includes 500 AI operations per month and needs no credit card.

You can create 4 different variations of a Socket.IO server with minimal code changes. And trust me you do NOT want to use the default one. I will be comparing combinations of the runtime (Bun, Node) and the websocket server (ws, uWebSockets.js, bun engine) to see how they perform under load. - Source: dev.to / 7 months ago
One possible solution is to use websockets, which establish a persistent connection between the client and server. This will allow us to send data to the client when we want to, without waiting for the clientโs next request. Websockets have their own protocol (though the connection is initiated with HTTP requests) and are language-agnostic. We could, if we wanted, implement a websocket client and its corresponding... - Source: dev.to / 8 months ago
Socket.IO is a JavaScript real-time chat library, you can read the documentation here since itโs outside the scope of this article, but I will try to explain a little that will be useful for this article. - Source: dev.to / 11 months ago
