Run Embers from Claude
Your relationship database, kept current by the assistant you already talk to.
Nick Sims · July 3, 2026
The hardest part of any relationship system isn't the software. It's the upkeep nobody does.
You meet someone worth knowing and mean to add them. You don't. Someone gets promoted, and their record falls behind. The work of keeping it all current turns into its own chore, so it slides, and a few months later, your database is half true, and you have quietly stopped trusting it. Every tool in this category fails the same way. Not from a missing feature. From the maintenance tax.
So we moved the maintenance to the assistant you already talk to. Embers now runs from Claude as a full read-and-write surface. Not just "connect and look." You run the whole thing by asking.
Read the whole network, not one card at a time
You can finally point your agent at everyone. "List the people I haven't logged anything on in months." "Who is missing an employer or an email?" It pages through your entire network and tells you where the gaps are, so a cleanup that used to mean an afternoon of clicking becomes one question.
Write to it by talking
This is the leap. Add a person with everything you know about them in one sentence. Fix a title after a promotion. Log that you grabbed coffee with someone, which quietly marks them as freshly in touch. Record that two people are married, or used to work together. The record updates the way you would describe it to a colleague, because that is exactly what you are doing.
It keeps itself current while you work
Put the first two together and the database starts maintaining itself. The standing instruction that does the most:
"Look at my last thirty days of meetings and my calendar, add everyone I met with twice, log what we covered, and queue a follow-up where I committed to something."
The agent reads the sources and writes the people, the notes, and the drafts into Embers. You did the meetings. The record of them now writes itself.
Two lines we hold no matter what. Nothing sends without your yes, so every captured follow-up waits for you. And the agent keeps only the derived facts, never the raw meeting notes or articles it read to get them. It is your network, walled off to you alone.
Stop maintaining your network by hand. Run it from Claude.
