nuntius

Draft Slack and Microsoft Teams replies with Claude or a local Ollama model, right inside each app.

nuntius is a side-panel assistant for Slack and Microsoft Teams that helps you draft replies without leaving the conversation you are already in. Open a thread, channel, DM, or Teams chat, then generate a suggested reply directly from the page context. The extension reads the recent conversation, lets you choose a tone, and inserts a draft into the correct composer so you can review and send it yourself. Why teams use nuntius: Works inside Slack and Microsoft Teams in one extension. Drafts replies in context instead of making you copy and paste chats into another tool. Supports Claude through a local native host setup. Supports local Ollama models for private, on-device workflows. Lets you steer tone with moods like professional, direct, empathetic, playful, technical, or one-liner. Saves personal voice samples and optional profile details to better match your writing style. Includes a side panel that stays docked while you work. Supports light and dark theme syncing. Typical use cases: Catch up on a long thread and draft a polished response quickly. Rewrite a message to be more concise, warmer, firmer, or more executive-friendly. Answer internal questions in your own style with less typing. Keep sensitive workflows local by using Ollama on your machine. How it works: Open Slack or Microsoft Teams in Chrome. Open the nuntius side panel. Choose your provider, tone, and optional instruction. Generate a draft. Review the inserted message before sending. Important notes: nuntius only works on Slack and Microsoft Teams web apps. Claude support requires a one-time local native host installation. Ollama support requires a local Ollama instance and installed model. You stay in control of the final message. Drafts are inserted for review, not auto-sent.
