Hey Everyone! We’re Praxim.

The Problem:

Microsoft Word serves over a billion users, but Copilot is still stuck in the Stone Age, requiring manual selection just to generate crude, format-ignoring block replacement edits completely devoid of context from your preferences, files, or the web.

The Solution:

With a single prompt, Praxim makes edits across your entire document:

  • No required manual selection to edit
  • No more copy-pasting and context switching between different apps
  • No formatting worries
  • Takes into account your preferences

Praxim knows exactly what to change and what to keep and edits with word-level granularity—precisely editing only what needs editing, not making brute block replacements.

Most importantly, Praxim creates real Word formatting:

  • Actual lists, tables, and styles—not fake imitation structures that are actually just paragraphs
  • Maintain formatting, or even change it

Pull data, research, and edit all without leaving Word, with features that 10x your productivity:

  • File and Web context
  • Voice dictation at the speed of thought
  • Intuitive edit previews and clickable references that jump to the location in the document

Praxim is already used for use cases from form filling with data from multiple sources to contract redlining with precise legal edits.

Why only now? Programmers left the era crude AI assistance years ago with agentic code editors. Formatted document editing is a far harder technical problem—a single word is encoded by formatting and structural markup several orders of magnitude more complex than plaintext code, with countless ways to render correct text incorrectly. Semantic meaning and formatting both matter.

Praxim for Word solves this, delivering a quantum leap over any other Word editing tool today. Start using Praxim today at praxim.ai!
