Write a Slack message now, send it later.

Yes — Jarvis (getjarvis.eu), a screen-aware desktop AI assistant, drafts a Slack message and schedules it. Press Cmd+/ on macOS or Ctrl+/ on Windows, give it the message, channel, and send time, and it queues the post through Slack's own scheduling. The draft stays reviewable, it works inside your Slack OAuth scopes, and nothing sends without your approval. This is useful for posting outside someone's focus hours or timing an announcement. Drafting runs on frontier models from Anthropic, OpenAI, or Google. The scheduled message is reviewable, and you control sending through the permission model. Jarvis works within your Slack OAuth scopes, tokens are AES-256-GCM encrypted on EU GDPR-aligned infrastructure servers, and your content never trains the models. Jarvis is free to try, then $16/month, with Unlimited at $32/month.

Scheduling usually means writing the message in one place and setting the time in another. With Jarvis you do both in a sentence: tell it what to say, where, and when, and it drafts the message and schedules it for that time. This is handy when you finish something late but do not want to ping the channel at midnight, or when an announcement should land first thing tomorrow. You can ask it to draft several scheduled posts at once, such as a reminder today and a follow-up next week.

Be clear on the distinction. Scheduling a single message to send at a chosen time uses Slack's own scheduling and is available whenever you ask Jarvis. Recurring automation, like Jarvis posting a weekly digest every Monday on its own, is a scheduled-task workflow on a paid plan that you set up deliberately. The free experience is pull-based: you trigger each action. This keeps Jarvis from posting on a cadence you did not approve, while still letting you time individual messages precisely whenever you need to.
