If you run an agency, the most expensive thing you do every single day is re-explain your clients to your own tools, and hermes obsidian memory is how you stop doing it.
Here is the problem nobody talks about: your AI agents have amnesia.
One agent drafts a brief, another writes the copy, a third does outreach, and not one of them remembers what the client actually sells, who they sell to, or what tone makes them flinch.
So your team becomes a human glue stick, re-briefing every agent, every session, on context that should already be locked in.
That is not a tooling problem. That is a memory problem. And it is solved.
The real cost of an AI team with no shared brain
Most agencies bolt AI onto a broken foundation.
They give every account manager a Claude tab, every writer a Gemini window, every ops person their own prompt library, and they call it an AI team.
It is not a team. It is a room full of strangers who have never met your client.
Without a shared brain, here is what actually happens across the week:
- Your strategist tells the AI the client’s positioning on Monday. Gone by Tuesday.
- Your copywriter re-pastes the brand voice into every single prompt, forever.
- Two agents produce two contradictory recommendations for the same account, and a human has to referee.
- A new team member onboards by asking the same questions the AI already had answers to last month.
- Every output sounds a little generic, a little off-brand, because the model is guessing instead of remembering.
That drift is silent and it compounds.
It is the difference between a lean team that scales and a busy team that just burns tokens re-establishing context it already paid for once.

The fix: hermes obsidian as one shared brain
The fix is embarrassingly simple, and it is free.
You take Hermes (free, open source) and you point it at an Obsidian vault (a free markdown folder), and together they become a permanent shared brain.
Call it an infinite context engine if you like: a single store of goals, notes, client facts and business context that never forgets and never resets.
The magic is not the vault itself. The magic is who reads it.
The same Obsidian vault is read by Hermes, Claude, OpenClaw, Gemini and Antigravity.
So every agent, and every team member’s AI, pulls from one set of facts about each client and business.
They speak in one voice. They align instead of clashing.
One agent drops a note about a client’s new product line, and the next morning another agent reads it before it writes a word. That handoff is the wiring. That is the whole game.
Why this changes the economics of client work
When the context lives in the shared brain, three things happen at once.
First, outputs become personalised and grounded in the real business, not generic filler that could belong to any client.
Second, you burn fewer tokens, because you stop pasting the same brand brief into every prompt and you stop re-prompting agents that should already know.
Third, the loop gets sharper daily, because Hermes writes the notes as work happens. The brain learns the client while the team delivers.
For an agency, that is not a nice-to-have. That is the operating leverage.
Without a shared brain vs with hermes obsidian memory
Here is the honest before-and-after for a team doing client work at volume.
| Team & client work | Without a shared brain | With hermes obsidian memory |
|---|---|---|
| Client context | Re-explained every session, in every tool | Lives once in the vault, read by every agent |
| Agents (Claude, Gemini, OpenClaw, Antigravity) | Each guesses; outputs clash | One voice, one set of facts, aligned |
| Handoffs between agents | Lost; humans re-brief | One drops a note, another reads it next morning |
| Output quality | Generic, off-brand, needs heavy edits | Personalised, grounded in the real business |
| Token spend | High, paying to re-establish context | Lower, no re-prompting |
| Onboarding a new hire | Re-asks what the AI already knew | The brain already holds the answers |
| Over time | Drifts further out of sync | Gets sharper daily as Hermes writes notes |
Read the right-hand column again. That is what a lean team looks like when it stops fighting its own tools.
How a 70+ person agency actually runs on a shared brain
I am not theorising here. Goldie Agency is a real seven-figure SEO and link-building agency with a 70-plus person team, and AI already handles a large share of our operations.
The only reason a lean team can keep client work consistent at that scale is the memory layer.
When every agent and every person draws on the same shared brain, consistency stops being a discipline problem you police and becomes the default behaviour of the system.
A new client gets onboarded into the vault once. From that moment, every brief, every draft, every outreach email is grounded in that client’s real facts.
Nobody has to remember to stay on-brand, because the brain remembers for them.
That is the difference between an agency that scales by adding bodies and an agency that scales by adding context.

Best home for the shared brain: a mission-control Agent OS
A shared brain is powerful on its own, but it is at its best when you can see the memory and the work in one place.
That place is a mission-control Agent OS: one dashboard where your agents, your vault and your active client work all live together.
You watch a note get written, you watch the next agent pick it up, you watch the work move. No more guessing what your AI team knows.
And you do not have to build it by hand. Hermes can build the mission control for you.
What if our notes are a mess right now?
Most agencies have a graveyard of half-written docs, scattered briefs and dead Notion pages. That is fine.
If your vault is messy, Hermes organises it and colour-codes it for you.
And if you want the inputs handled automatically, OMI (free) can auto-sync memories straight into Obsidian, so context flows into the shared brain without anyone manually filing it.
You do not need a clean start. You need a system that cleans itself as it goes.
Where this earns its keep
This shared-brain approach pays off hardest anywhere the output has to sound like a specific client or brand:
- Client work where consistency across a 70-plus person team is non-negotiable.
- Content strategy that has to stay anchored to each client’s positioning, not the model’s generic instincts.
- Copywriting where one wrong-sounding line undermines the whole brand.
- Any output where “close enough” is not good enough and the voice has to be exact.
If your work lives or dies on sounding like the client, a shared brain is not optional. It is the foundation.

Frequently asked questions
What is Hermes Obsidian memory for an agency?
It is a shared brain made from Hermes (free, open source) plus an Obsidian markdown vault. The same vault is read by every AI agent and team member, so client and business context stays in one place and every output is grounded in the real account rather than generic guesses.
How does a shared brain keep an AI agent team aligned?
Every agent reads and writes to the same Obsidian vault, so Claude, OpenClaw, Gemini and Antigravity all speak in one voice with one set of facts about each client. One agent drops a note, another reads it the next morning, so the team aligns instead of clashing.
Is hermes obsidian memory actually free?
Yes. Hermes is free and open source, and Obsidian is a free markdown vault. OMI is also free and can auto-sync memories into Obsidian. You can start without paying for a memory layer.
What if our vault is a mess?
Hermes organises and colour-codes a messy vault for you, and it writes notes back as the team works, so the shared brain gets sharper every day instead of decaying.
Where does it work best?
Inside a mission-control Agent OS, where you see the memory and the work in one dashboard. Hermes can build that mission control for you. It shines on client work, content strategy and copywriting.
