Hivemind coordinates agents right now.
Kleio remembers what they decided last month.

Where Hivemind works well

• Multi-agent coordination with a shared event log — agents publish decisions and query each other.
• Semantic search across events with vector embeddings and sub-50ms query latency.
• File locking prevents agents from clobbering each other's work in parallel.
• Event triggers enable reactive workflows — when all modules complete, deploy.
• Task state derived from the event stream — no separate task database needed.
• Quick setup — MCP-based, 30-second install.

Where Hivemind breaks down

• Coordination-focused — designed for agents working in the same session, not decisions across weeks or months.
• No structured decision primitive — events are generic, not typed as decisions, checkpoints, or work items.
• No backlog synthesis — events don't turn into prioritized, deduplicated work items.
• No GitHub integration — PRs, reviews, CI results, and team workflows are outside its scope.
• No provenance trails — can't trace a line of code back to the decision that created it.
• No human-in-the-loop decision capture — designed for agent-to-agent communication.
• Persistence model is scoped to the coordination session, not long-term organizational memory.

How Kleio is different

• Persistent memory across sessions, contributors, and time — not just coordination within one session.
• Structured primitives: decisions, checkpoints, and work items with distinct semantics.
• GitHub App integration captures PRs, reviews, commits, and CI as first-class signals.
• Backlog synthesis with Eisenhower prioritization and semantic deduplication.
• Provenance trails link decisions to the code changes they produced.
• Captures both human and AI decisions — meetings, Slack, and PRs matter too.
• kleio_ask provides RAG-based retrieval over months or years of engineering history.

Side-by-side

Better together or full replacement?

Different problems. Hivemind answers "what’s happening right now across my agents?" — it’s a coordination layer. Kleio answers "what did we decide about X last month and why?" — it’s a memory layer. They could potentially complement each other: Hivemind for real-time agent coordination, Kleio for persistent organizational memory.
