Do I need crypto or a wallet to use SAIHM?

No. The free tier needs no payment method at all, and paid plans can be paid by card through Stripe, or by card and M-PESA through Paystack in Africa. Stablecoin is an option for people who prefer it, and it is the only route that needs a wallet.

Can SAIHM read my memories?

No. Each memory is encrypted on your device before it is stored, so SAIHM, your agent vendor and whichever node holds the encrypted copy all see ciphertext only.

What happens if I lose my key?

The memories sealed with it cannot be recovered, by you or by anyone else. That is the same property that makes erasure real, and it is why the key is worth backing up the way you would back up a password manager.

What does “forget that” actually do?

It destroys the key that decrypts the memory. Copies, replicas and backups are left as unreadable ciphertext rather than merely hidden from search, which is the difference between erasure and de-listing under the right to erasure.

Does my memory survive if I switch AI agents?

Yes. Memory is held under your key rather than inside one vendor’s account, so a new agent that speaks the same protocol reads the same memory and carries on.

Tell your agent “Join SAIHM.”

That’s really it. Your AI agent gets a memory that travels with you, that you control, and that you can wipe in one sentence whenever you choose.

Why this matters

Right now, your AI agent forgets you between conversations — or, worse, it remembers you on someone else’s server, in someone else’s shape, under someone else’s rules. SAIHM flips that.

Sovereignty. Your AI Agent’s memory belongs to you, not to whoever made the agent.
Privacy. Memories are sealed before they leave your device. Nobody else — not us, not your agent vendor — can read them.
Sharing, on your terms. Want a teammate, a doctor, an accountant, or another agent to see a specific note? Grant access. Revoke it whenever.
Persistence. Switch apps, switch agents, upgrade your phone — your memory is still there.

SAIHM is not an AI agent

SAIHM is the memory layer that any AI agent can use. Commercial assistants, the open-source ones you install yourself, brand-new agents that haven’t shipped yet — if it speaks the standard agent protocol, it can use SAIHM. That matters because:

You are not locked to one vendor. Your AI Agent’s memory outlives the agent you use today.
Open-source agents get the same memory layer as the big commercial ones. The playing field is level.
You can switch agents the day a better one launches and your memory follows you.

How to join

Start free. No card, no wallet, no crypto, nothing to install beyond your agent. Most people never need anything else, and the free tier stays free — it is not a trial.

1. Free — one sentence

Tell your agent: “Join SAIHM.” If you drive it from a terminal, that is one command:

npx -y @saihm/mcp-server-pro free-join

It shows a short code and a link; open the link and approve with your GitHub account, and your agent has memory from that moment. Prefer Google or Microsoft? Start from /free in a browser instead — same free tier, same key. Nothing to configure and no payment method to enter.

2. Paid — pay by card

When you outgrow the free allowance, say “Join SAIHM at Pro.” Paid plans are monthly.

Card, worldwide. Handled by Stripe. SAIHM never sees your card details.
Card and M-PESA, Africa. Handled by Paystack, priced in Kenyan shillings. An M-PESA payment buys one month outright rather than starting a subscription, so there is nothing to cancel.

Both routes are on the Join page, and the prices are on the pricing page rather than quoted per customer.

3. Paid — stablecoin, if you prefer it

If you already hold stablecoin and would rather pay that way, you can. It is an option, not a requirement, and it is the only route that needs a wallet. The quickstart walks it through with the expected result at every step; pricing covers what settles and what does not.

Picking a tier

Just tell your agent. Examples:

“Stay on the free tier.”
“Use pay-as-you-go for now.”
“Join SAIHM at Pro — put it on my card.”
“Join SAIHM at Pro Fast — high-volume month.”

Quotas and rates are on the pricing page. PAYG is pennies per call for everyday use.

Real-world examples

Names invented; circumstances drawn from how the protocol actually fits.

Maya, freelance designer. Six active clients across two countries; her assistant remembers each client’s brand rules, contract dates, and who pays late. When a contract ends, she tells the assistant to forget that client — the underlying memory key is destroyed and the conversation cannot be reconstructed later, even by accident. PAYG covers her light months; the Pro tier handles the busy ones.
Hassan, parent of three. The family assistant keeps each child’s allergies, school timetable, and dietary rules. When the school nurse asks for the allergies note ahead of a field trip, Hassan grants temporary, single-record access; the nurse reads exactly that one cell, the share auto-revokes, and nothing else moves.
Priya, late-career professional. Her financial-planning assistant tracks years of advice, retirement timelines, and tax-loss carryforwards. She is not willing to hand that detail to whichever AI vendor she happens to be using today — SAIHM keeps the memory hers across vendor switches.
Tomás, language learner. His Spanish tutor app remembers his vocabulary gaps, his accent progress, and which tenses still confuse him. When a better tutor app launches, he switches in five minutes; the new tutor reads the same memory and picks up where the old one left off.
Aiko, solo entrepreneur. Her sales assistant remembers every lead, every objection answered, and every follow-up promised. When she onboards a contractor for two weeks, she shares the “current pipeline” cell read-only and revokes when the engagement ends — no per-seat license to renegotiate.

What if I change my mind?

You can wipe a memory whenever you want. Tell your agent “forget that” and the underlying key is destroyed — the memory cannot be reconstructed by anyone, including us. You can also cancel a subscription, switch tiers, or move to a different agent without losing what you have already remembered.
