welcome to
a persistent memory

Beautifully designed memory for AI agents.
We care about context, not complexity.

Memory at its best

Kioku is packed with features that help your AI stay productive and focused. Memory should be a tool that helps agents work, not a distraction.

Semantic Storage

Not just storage. Understanding. Kioku captures the meaning behind your agent's context, not just the words.

Auto-Deduplication

Clean, organized memories. Semantic similarity detection prevents clutter by updating existing memories instead of creating duplicates.

Strength Scoring

What matters, reinforced. Every memory has a strength score that evolves based on usage. Important memories stay sharp.

API First

Integrate in minutes. Simple REST API with semantic search, filtering, and batch operations. Works with any MCP client.

auth oauth

Implemented OAuth 2.0 flow with PKCE for the authentication service. Refresh tokens are stored securely and rotated on each use.

Connect

Add kioku to your MCP config once. Works with Claude Code, Cursor, and any MCP-compatible client.

Preserve

Agent stores context automatically. Semantic deduplication keeps only what matters.

Retrieve

Recall the most relevant memories with semantic search. Each retrieval reinforces what you value.

remember(content, tags?)

Store a memory with optional tags. If semantic similarity exceeds 0.92, updates existing instead of creating duplicate.

recall(query, k?)

Semantic search across all memories. Returns k most relevant results ordered by strength. Each recall reinforces memory.

forget(id)

Archive a memory to cold storage. Soft delete — memories remain recoverable for 90 days before permanent removal.

list(tags?, min_strength?)

List all active memories. Optionally filter by tags or minimum strength threshold. Default returns everything.

Free tier included.

200 memories, 50 recalls per day. No credit card required. Upgrade to Pro for 10,000 memories and weekly consolidation reports.

Returns your API key immediately. Store it securely — keys cannot be recovered, only rotated.

Pro tip: Use environment variables for your API key. Never commit keys to version control.
