Pricing
Start free with a one-time lifetime allowance, then pay only when you grow: a flat monthly subscription, or pay-as-you-go (PAYG) per call. Every paid tier delivers up to ~80% AI token savings — recalled memory replaces context you would otherwise re-send on every request.
Paid plans settle by card via Stripe, or in USDC.e on COTI V2 mainnet (canonical, no premium) — directly from your wallet, or via a gasless signed-authorisation email if you don’t hold COTI for gas.

Paid plans are monthly subscriptions; cancel anytime. Subscription tiers hard-cap at their monthly quotas — no surprise overage billing. Token-savings figure reflects agent workloads where recalled memory replaces re-sent context; actual savings vary by workload. SHM (Super-Human Memory) — an Enterprise-tier add-on for semantic recall, concurrent-thread continuity, and consolidation — is announced here; availability and terms are discussed directly.
Free
Activate a free, one-time lifetime memory allowance — no card. It is a fixed allotment of writes, reads, and shares that never resets or refills (it is not a trial). Every memory is sealed under a key only you hold, from the first cell.
Activate from the command line with a one-time GitHub device sign-in that confirms a unique person — the sign-in stays in your browser and no token is ever handed to SAIHM:

Pay-as-you-go (PAYG)
No subscription. Each call settles on-chain at write time.
| Operation | USD / call |
|---|---|
| Remember | $0.10 ($10 per 100 writes) |
| Recall | $0.05 ($10 per 200 reads) |
| Forget (cryptographic erasure) | $0.10 ($10 per 100 forgets) |
| Sharing — TEMPORARY (under 24 hours, limited) | $1.00 / grantee |
| Sharing — PERMANENT | $10.00 / grantee |
| Sharing — SYNDICATE | $25.00 / grantee |
PAYG break-even vs Pro ($50/mo): Remember at 500 writes/month; Recall at 1,000 reads/month. Below those volumes, PAYG is cheaper than Pro on the corresponding operation. Pro’s value is in its 1-year audit retention, dedicated call quota, and included sharing contracts.
PAYG audit retention: 30 days. Longer retention requires a subscription tier.
Billing and refunds
All payments are final. Subscriptions and pay-as-you-go calls are non-refundable. Cancel anytime to stop the next renewal; the current paid period continues to its end with no further charges.
Sharing by plan
| Plan | Sharing | Allowance |
|---|---|---|
| Pro | yes | 250 contracts/mo |
| Pro Fast | yes | 2,500 contracts/mo |
| Enterprise | yes | 5,000 contracts/mo |
| Enterprise Fast | yes | unlimited |
| PAYG | yes | per-grantee (see PAYG table) |
A share grants the named grantee read access to a specific cell only. Receiving a share does not change the grantee’s own subscription tier and does not confer re-share rights; only the original cell-holder may extend or revoke access.
Payment methods
You can settle in any of the following:
- Fiat via Stripe (subscription tiers): pay a monthly tier by card or another Stripe-supported method at Join — no crypto, no gas, no bridging. Subscriptions are processed by Stripe, renew monthly, and can be cancelled any time. Pay-as-you-go settles on-chain in USDC.e.
- USDC.e on COTI V2 mainnet (canonical, no premium): the bridged USD Coin already native to COTI V2. Pay your tier address directly.
- Gasless via signed authorisation (email): sign an authorisation in your wallet (off-chain, zero gas), email it to join@saihm.coti.global, and your tier settles in USDC.e on-chain with no gas paid by you. See below for how to start.
Tier selection is performed by your AI agent on your behalf — you say “Join SAIHM at the Pro tier” and it handles the rest.
Decision matrix
Side-by-side comparison of your payment options. Pick what matches what you already hold.
| Method | Premium | Customer gas | Prerequisite | Typical wall-clock | Best for |
|---|---|---|---|---|---|
| Fiat via Stripe (card & other methods) | none | n/a (fiat) | a Stripe-supported payment method; subscription tiers only | instant | subscribers who want to pay in fiat with no crypto, gas, or bridging |
| Direct USDC.e on COTI V2 | none | customer pays | USDC.e + small COTI (for gas) on COTI V2 | seconds (one transaction) | buyers who already hold COTI for gas and want on-chain control |
| Gasless via signed authorisation (email) | none | zero | USDC.e on COTI V2 (no COTI required) | a few minutes | buyers who hold USDC.e but no COTI, or don’t want to manage gas |
Coming from Ethereum L1? See below for the bridging-in path.
Coming from Ethereum L1?
If you hold USDC on Ethereum L1, self-bridge it to USDC.e on COTI V2 via Hyperlane Nexus, then your tier payment in USDC.e settles normally. SAIHM does not orchestrate the bridge — you sign the bridge transaction and pay the bridge fee, the same way you would for any cross-chain transfer.
If you hold a different Ethereum stablecoin (USDT, DAI, etc.), swap to USDC on Ethereum first using any DEX of your choice, then bridge as above. The swap is your decision, your DEX, your transaction; SAIHM is not in the swap path.
Verified route: Ethereum L1 USDC → Hyperlane Nexus → USDC.e on COTI V2 (mainnet-verified bidirectional, 2026-04-29).
What SAIHM does: accepts your USDC.e payment on COTI V2 once it arrives at your tier address. What SAIHM does not do: custody on Ethereum, hold balances on Ethereum, sign your bridge transaction, or perform a swap on your behalf.
Only USDC.e on COTI V2 mainnet settles your tier. Assets that arrive in any other form — USDT, DAI, native ETH, native COTI sent to a USDC.e tier address, or anything bridged to a non-USDC.e contract — will not credit your account. If you are unsure, complete the bridge first, verify the asset on mainnet.cotiscan.io as USDC.e at the contract 0xf1Feebc4376c68B7003450ae66343Ae59AB37D3C, and then send to your tier address.
Gasless via signed authorisation (email)
What: sign a message in your wallet (off-chain, no gas), email the signed envelope to join@saihm.coti.global, and SAIHM settles your tier on-chain in USDC.e at zero customer gas. Mainnet-validated 2026-05-05.
Best for: you already hold USDC.e on COTI V2 but don’t want to manage COTI for gas.
Your AI agent can do this for you — say “Join SAIHM at the Pro tier” and it handles the signing and the email. Join SAIHM →
