Bourdon vs Cogni vs Knownbase (Agency Memory Architecture Tradeoffs)
These three solve different halves of the same agency problem: Bourdon optimizes for instant recognition across a multi-tool stack, Cogni for reasoning over linked client facts, and Knownbase for a durable per-project record. The decision hinges less on feature lists than on whether your delivery model needs speed of recall, depth of inference, or an auditable archive, and on how cleanly each layer exports if you switch. Whichever you pick, test the export path before you migrate a single client account, because a memory layer that traps institutional knowledge converts a tooling decision into a retention risk.

Which should an agency choose?
Bourdon vs Cogni vs Knownbase (Agency Memory Architecture Tradeoffs)
Bourdon
Best for: Agencies running one delivery pod across four or more AI coding tools where recall speed matters more than archive structure.- Recognition-first recall keeps latency near zero because a fact learned by one agent is recognized by the others without a search step
- Federates memory across Claude, Codex, Cursor, Copilot, and Devin, so a discovery made in one tool does not have to be re-taught in the next
- Shared knowledge spans accounts and machines, which suits a delivery pod where three people rotate across the same client build
- Recognition depends on the federation staying connected; a tool outside the supported set falls back to stateless behavior
- Federated memory spreads client context across every connected agent, so access review has to happen at the federation layer rather than per tool
- No white-label option, so the memory layer cannot be resold as part of a client-facing retainer deliverable
Cogni
Best for: Agencies whose client work depends on linked decisions, such as architecture choices that cascade into campaign constraints.- Entity-graph spreading activation reaches connected facts that a plain vector store misses, which helps when a client's brand rules and technical constraints are linked rather than co-located
- Retrieval runs deterministically with no LLM or GPU in the path, so recall cost stays flat as the graph grows
- Model-agnostic design means the memory survives a swap of the underlying model provider
- Graph construction is front-loaded work; someone has to define entities and relationships before recall quality shows up
- Multi-hop reasoning is the selling point, and teams that only need keyword lookup will pay complexity for capability they do not use
- Cross-vocabulary retrieval still needs a naming convention across client accounts or the graph fragments into near-duplicate entities
Knownbase
Best for: Agencies that need an auditable per-client record of decisions and constraints rather than instant cross-tool recall.- Stores architectural decisions, debugging discoveries, and project constraints as notes organized by project and tag
- Connects Claude Code, Codex, Cursor, and ChatGPT through MCP, so the archive is readable regardless of which agent is active
- Project-scoped structure maps cleanly onto per-client folders, which keeps one client's constraints out of another's context
- Archive-style memory depends on agents writing notes; a session that never writes leaves no trace for the next one
- Tag hygiene degrades as the number of client projects grows, and stale tags quietly pollute retrieval
- Search-based recall adds a lookup step that recognition-first systems avoid
