Draftspect — open Word or Excel and chat with your own local Claude Code: it reads and edits the document and can pull in any local folders/files you point it at (notes, drafts, data, a repo) as context. Your configured agent — MCP, skills, CLAUDE.md — on your machine. Powered by Claude Code.

AI Summary

Draftspect is a free add-in that brings an AI assistant directly into Microsoft Word and Excel. Instead of copying your text into a chatbot elsewhere, you open a side panel inside your document and chat with an AI that can read, edit, and improve your work in real time. In Word, the AI makes edits as tracked changes so you can review every suggestion. In Excel, it writes formulas, creates charts, and manages your data. The AI uses your own locally-installed Claude Code, meaning it can access folders and files on your computer as background context—your notes, previous drafts, or any reference material you point it to. Everything stays on your machine; only the document content goes to the AI service to get a response.

How It Works

1
💡 You want AI help while writing in Word

You're working on a document and wish you could ask an AI to summarize, edit, or review it without leaving Word.

2
🖥️ You install Claude Code on your computer

You download and set up Claude Code, the same AI assistant you might already use in a terminal, signing in with your account.

3
📦 You download and start Draftspect

You download Draftspect from the internet and run a simple start command. A small icon appears in your menu bar.

4
✨ A helpful panel appears inside Word or Excel

You open your document, click a button, and a chat panel slides open on the right side of your screen.

5
📁 You point it at your reference files

In the Settings tab, you add folders from your computer—your notes, previous drafts, or research files—so the AI can read them as background context.

6
You chat with the AI about your document
📝
In Word: edits appear as tracked changes

The AI rewrites paragraphs, adds comments, or highlights issues—and every change shows up as a tracked change you can review.

📊
In Excel: formulas and data appear in cells

The AI writes SUM formulas, adds new rows, creates charts, or explains what your data means—all in your live spreadsheet.

✅ Your document is polished and ready

You review the AI's suggestions, accept what you like, and send it off—your document now has professional edits, comments, and formatting.

What is Draftspect-Add-Ins-for-Word-and-Excel-Powered-by-Claude-Code?

Draftspect is an add-in that drops a chat panel directly into Word and Excel, letting you talk to your own local Claude Code while you work. It reads your document, edits it, adds comments, and writes formulas — all through conversation. The key differentiator: you can point it at any folder on your machine (notes, prior drafts, a repo, a data export) and Claude reads those files as background context while it works in your document. It runs your configured agent with all your MCP servers, skills, and CLAUDE.md settings intact.

Built in JavaScript using Electron for the tray app, a Node daemon that wraps the Claude Agent SDK, and Office.js for the task pane UI. The daemon speaks WebSocket to the panel and forwards your local MCP servers into each session.

Why is it gaining traction?

The official Claude for Word/Excel add-in is polished and zero-setup, but it only sees documents you have open. Draftspect reaches beyond Office into your entire filesystem. If you need Claude to cross-check a contract against your `~/Research` folder, or fill a spreadsheet from last quarter's data export, that's the hook.

It's also open source. You can clone it, tweak the UI, add custom presets, or modify the system prompts. For developers who live in Claude Code already, having that same agent work inside their documents — with the same tools and context — is the draw.

Who should use this?

Writers and analysts who want AI assistance that knows their whole project, not just the open file. Researchers comparing drafts against reference materials. Developers who track notes in plain text and want that context available while editing a Word doc. Anyone with Claude Code configured who prefers working in Office over the terminal.

Not for teams needing a shared, hardened service. Windows users should note that macOS is the primary platform.

Verdict

This is a clever, well-documented project for a specific niche: Claude Code power users who want document AI with local file context. The credibility score of 0.899% reflects its early stage — 11 stars, limited Windows testing, and no production hardening. If that profile fits you, it's worth a weekend to set up. If you need stability or cross-platform confidence, wait for more traction.
