Description
From the marketplace listing
You can't remember everyone. Orbit can. Orbit keeps track of who you've talked to on Substack, what you discussed, and where things stand, and what your writing does. Ask ChatGPT about your Substack people and your writing, and it answers from your own Orbit data.
With Orbit, you can:
• Know who to talk to: the subscribers who read everything and have never heard from you, five people worth talking to today, and who's gone quiet.
• Get your Substack briefing: Orbit asks once what matters to you, then brings you the people paying attention to you, the conversations slipping away, and the people worth knowing.
• Catch up before you reply: what you and someone talked about before, and the replies still waiting on you.
• See what's working: ask what's working in your Notes lately, whether you're reaching new people or the same ones, and what to do differently next week. Orbit finds the patterns across your Notes and essays and shows your own examples as the evidence.
• Meet the people behind your numbers: who subscribed after each Note or essay, who replied and restacked, and which of them you already talk with.
• Find what you said before: search your Notes, essays and comments for the conversation you know you had.
Every answer links back to Substack.
When you ask, Orbit can also save a private note or tag on a person, clear a reply from your queue, hide someone from your reminders, mark a DM's status, or save your briefing settings and preferences. It never posts, comments, or sends messages on Substack.
Requires an Orbit account. Orbit fills itself in through its Chrome extension while you use Substack as usual; your Substack login stays on your computer. Direct messages are included only if you turn them on.
Orbit is an independent tool and isn't affiliated with Substack.
