One memory per client. Walls between them.
hyyve is the client memory layer for solo consultants, agency owners, and fractional operators. It turns scattered client context into reviewed memory your AI tools can use: in ChatGPT and Claude, with nothing to install and no client ever mixed with another.
Your AI only sees the client you allow
Meridian: invoice net-30 via their Hamburg entity, not the holding.
Never mention competitor pricing in anything drafted for Nordwind.
Kickoff for the Baumann rebrand moved to October 14.
Every card belongs to exactly one client. No bleed, no mix-ups, no awkward drafts.
Every card links to the email, note, or call it came from.
You sign off before anything becomes memory your AI can use.
hyyve works where you already work: ChatGPT, Claude, your email, notes, and files. Each one stays the source of truth.
You already told your AI this. Three times.
You juggle a dozen clients, and the context lives everywhere except where your AI can use it: email threads, call notes, old proposals, your head. Every new chat starts from zero, so you re-explain the same client again. Or worse, ChatGPT remembers the wrong one and client A's details surface in client B's draft.
From scattered context to client memory in four steps.
The same flow runs whether you paste a note or forward an email, and you sign off before anything becomes memory.
Built like a database, not a doc.
Every source becomes a small, structured memory card with a client, a visibility level, and a freshness state. That structure is what makes it safe to hand to your AI.
Source-backed memory
Every card links back to where it came from, so you can always check the original.
Structured into cells
Each memory carries a client, a type, and a visibility level before any AI can use it.
Scoped for retrieval
Your AI reads one client's cards at a time, never your whole book of business.
The graph is the proof.
Every answer starts as a source, becomes a reviewed card, and only then can your AI read it. You can follow that path at every step.

Vault gateStale, private, and conflicting memory stays out of your AI's reach until you resolve it.
Your AI only sees the client you allow.
Use it from ChatGPT, Claude, or any agent you run. No terminal, nothing to install. hyyve keeps the source visible, the memory reviewable, and every access explicit.
Your AI reads one client at a time. Client A never leaks into client B's draft.
Memory needs your approval before any AI can use it. AI can suggest, never approve.

Pull access to a client instantly. When an engagement ends, so does the memory access.
One graph. Every source held, every memory reviewed, every client walled off.
Not a notes app. Not ChatGPT's memory.
hyyve is an inspectable client memory: source-backed, scoped per client, and easy to export. Native AI memory is personal and mixes everything; notes apps can't talk to your AI.

Is this just another notes app?
No. Your emails, notes, and docs stay the source of truth. hyyve keeps the extracted memory on top: small, source-backed cards per client instead of pages you maintain by hand.
How is this different from ChatGPT's built-in memory?
Native memory is one personal pool: it quietly mixes all your clients and you can't fully see what's in it. hyyve gives you one reviewed memory per client, readable card by card, with hard walls between clients.
How does it connect to my AI tools?
ChatGPT and Claude read hyyve directly. No terminal, nothing to install. Your AI queries the client you allow, gets cited answers, and every read is logged.
What can I bring in?
Start by pasting or forwarding what you have: emails, call notes, proposals, PDFs, recordings. Connectors for your other tools come next.
Can I export everything?
Yes. Every client's memory exports to Markdown with your raw files. When an engagement ends, you can hand the whole thing over or take it with you.
What is in the private preview?
A hands-on look at one client memory built from your real data, plus a direct line to shape what we build next.
Test hyyve on your messiest client.
hyyve is easiest to judge on real mess: context in email threads, decisions from calls, rules you keep re-explaining. Bring the client you re-explain most.
