Quickstart ​

What is OpenDocBot? ​

OpenDocBot is a 100% client-side, provider-agnostic AI agent for Microsoft Office (Word, Excel, PowerPoint). Connect your own API keys from any provider (OpenAI, DeepSeek, Anthropic, Gemini, Ollama, OpenRouter, OpenCode, or any OpenAI-compatible endpoint), and the model reads, writes and formats your content directly.

Bring your own keys and models, gate every action behind human-in-the-loop approval, or self-host it: your data never has to leave your infrastructure.

Try the hosted instance ​

A public instance is hosted at opendocbot.com/app. We only serve the add-in once, when your Office taskpane first loads; afterwards everything runs entirely on your machine and talks to your AI provider directly. No document data ever reaches our servers.

Requirements ​

  • Microsoft Office 365: Word, Excel or PowerPoint (desktop or web)
  • An LLM provider that allows browser access (see below)

1. Sideload the add-in in Office ​

⚠️ OpenDocBot is currently in Early Access. Microsoft Marketplace distribution is coming, but sideloading is currently required. This is the same OpenDocBot experience you'll get through Marketplace. We're onboarding power users now to help test the product, find edge cases, and shape what's next.

Office 365 Local ​

In case of having the Office 365 apps installed locally, the add-in can be sideloaded persistently.

Run the following command in PowerShell as administrator:

powershell
irm https://opendocbot.com/sideload.ps1 | iex

This command runs the https://opendocbot.com/sideload.ps1 script on your machine, which automatically configures persistent add-in sideloading via the network share method.

Admin Priviledges

This scripts requires admin priviledges due to the required creation of a local network share (New-SmbShare cmdlet). The script can be fully audited at https://opendocbot.com/sideload.ps1

Run the following command in Terminal:

bash
curl -fsSL https://opendocbot.com/sideload.sh | bash

This command runs the https://opendocbot.com/sideload.sh script on your machine, which automates the sideloading process for macOS: it downloads the manifest into the add-in folder (wef) of Word, Excel and PowerPoint.

Restart Word, Excel and PowerPoint, then check Home > Add-ins.

Note that clearing the Office cache removes the add-in.

Office 365 Web Version (any OS) ​

Download the manifest file from the link below and upload it in the app (Home > Add-ins > More Add-ins > My Add-ins > Manage My Add-ins > Upload My Add-in). Unfortunately this method does not load the addin persistently, the add-in may vanish on page refresh.

Download manifest.xml

Teams and IT-managed devices ​

Deploy the manifest.xml file centrally via the Microsoft 365 admin center: Manage deployment of add-ins.

Note that, despite using the hosted instance, none of your document data reaches our servers. Despite that, the the application serving can also be self-hosted for fully airgapped deployments.

OpenDocBot is Source-Available and 100% free for personal use and small teams (up to 30 users)

2. Connect a provider ​

  1. Open the add-in Settings (gear icon)
  2. Pick a Preset, paste your API key
  3. Test Connection, then Apply

3. Talk to your document ​

Type a request and press Enter; for example, in Word: "Make the selected heading green and bold." Or in PowerPoint: "Turn this deck into a retro wine label style."

Self-hosting ​

If you want full control, or need the proxy for providers without browser CORS (like OpenCode), you can run OpenDocBot on your own infrastructure. The full guide (Docker, Node, static hosting, HTTPS/TLS certificates, the proxy and production manifests) is on the Self-hosting page.
