Ask before purchase
The buyer seals the need, complete action set, constraints, and Outcome plan before seeing the result.
Buyer-side intelligence for AI agents
Memory for machine purchases.
Perpensum helps a buyer AI learn from purchase experience it could not collect alone—and knows when the evidence is too thin to answer.

↕Collective Experience Network
Current truth: the system is live; the independent cross-buyer network is just beginning. The implemented pilot profile is structured invoice extraction through Replicate. Other purchase types are not plug-and-play today.
The product
Experience first. Decisions second.
A payment dashboard can show what one account spent. Perpensum preserves the context, alternatives, choice, and observed result needed to learn what happened—and makes only bounded use of comparable experience.
Record what happened
The buyer purchases through its existing route, then appends the Choice and typed Outcome or explicit missing observation.
Answer within evidence
The Decision Engine separates direct evidence from looser signals and may prefer, collect more, or abstain. It does not invent certainty.
Why a network
A single buyer can optimize only from the failures and alternatives it has already seen. CEN is meant to preserve independent experience across buyers without turning raw customer data into a shared database.
Data boundary
The purchasing evidence enters. The private payload does not.
Stays with the buyer
- provider and payment credentials
- raw prompts, inputs, and outputs
- customer records and private artifacts
- purchase execution and final authority
Private purchase ledger
- typed goal and situation
- complete considered actions
- choice and purchase evidence digest
- typed Outcome, missingness, and time
Collective projection
- only consented, eligible fields
- independent-control accounting
- support, uncertainty, and limitations
- no public named-seller score
Cross-buyer price sharing is disabled for the first pilot.
First independent buyer
Three natural purchases. Thirty days. Free.
We are opening one private design-partner place for an AI-native operator already choosing repeatedly among two or more Replicate-hosted model offerings for structured invoice extraction. Purchases continue through the buyer’s existing Replicate path.
