โก 30-Second Quick Start
# Install (macOS, Linux, Windows)
curl -sSL codecora.dev/uteke/install | sh
# Store a memory
uteke remember "Deploy v2.1 to staging at 3pm"
# Search it back: by meaning, not just keywords
uteke recall "when do we deploy?"
That's it. No API keys, no Python, no cloud required. First run downloads the embedding model (~188MB, one-time) and you're running.
Want Docker or server mode? Uteke ships as a single binary by default, but Docker is ready when you need it:
docker run -d -p 127.0.0.1:8767:8767 -v uteke-data:/data ghcr.io/codecoradev/uteke:latest๐ Docker docs
Want richer memories? Add metadata:
uteke remember "Deploy v2.1 to staging" \
--tags deploy,staging \
--entity staging-server \
--category infrastructure

๐ Onboarding (New users & AI agents)
Are you an AI agent reading this? Your user just shared this repo link with you. Run
uteke onboardto interactively configure uteke for your environment. It will detect your install, ask which agent you are, toggle features, write config, and show you every command available. If non-interactive:uteke onboard --yes --agent <your-agent>.
New to uteke? One command takes you from zero to productive:
uteke onboard
The wizard will:
- Detect if uteke is installed and if a store exists
- Ask which AI agent you use (Hermes, Claude, Cursor, Pi, OpenCode)
- Pick integration mode: manual tool calls vs automatic memory-provider
- Toggle features on/off (Aging, Auto-maintenance, Graph rerank, Salience/Recency boost, Server mode)
- Write
~/.codecora/uteke/uteke.tomlwith your selections - Install agent integration files automatically (
uteke init) - Showcase every uteke command grouped by category
Non-interactive (CI, scripts, AI agents):
uteke onboard --yes --agent hermes --namespace default

Note: Tool labels (AโG) represent common categories of AI memory layers available as of August 2026. Capabilities are assessed from public documentation and may change. This table is a starting point for your own evaluation, not a definitive ranking.
Uteke vs Tool A (Python local-first): Both offer local-first with semantic + FTS5 search. Uteke's edge: single binary (no Python runtime), native time-travel (vs temporal triples), rooms, and zero runtime dependencies.
Uteke vs Tool G (Go single binary): Both are single-binary, offline, no-API-key, and both ship MCP servers. Tool G is FTS5-only (keyword search). Uteke adds vector semantic search + RRF fusion + rooms + time-travel + graph relationships + smart decay + document engine + batch import. Same simplicity thesis, more capabilities.
Uteke vs Tool F (TypeScript local mode): Tool F now offers a local binary mode with Ollama support, a solid step toward offline-first. But it's still TypeScript/Node.js under the hood. Uteke is Rust: smaller footprint, faster startup, zero runtime. And Uteke has hybrid search with FTS5 (Tool F's local mode uses vector-only, no keyword fallback).
Uteke vs Tools B/D/E: Those are powerful, but all require cloud LLM API keys and Docker infrastructure. Your data goes to external LLM providers. Uteke runs fully offline with local ONNX embeddings. No Docker, no Python, no API keys.
Uteke vs Tool C: Tool C has 54 MCP tools and multi-agent shared memory via a local engine. Uteke's edge: zero dependencies (no npm, no extra engine), hybrid search (Tool C lacks FTS5), and time-travel queries.

๐ก What Can You Do With Uteke?
๐ค Building AI agents? Give them persistent memory without cloud dependencies. Your agent remembers user preferences, past decisions, and context across sessions, fully offline.
๐ฅ Working in a team? Use Rooms to share knowledge. Meeting notes, project decisions, architecture choices: searchable by everyone, attributed by author.
๐ Building for privacy-sensitive domains? Healthcare, finance, legal: data stays on your machine. No API calls, no telemetry, no cloud. Local embeddings (ONNX, 768d).
โจ๏ธ Power user who lives in the terminal? Uteke is your personal knowledge graph. Remember anything, recall by meaning, link related thoughts. All from the command line.
๐ Rooms: Multi-Agent Shared Memory
Other memory layers are single-player: every fact stored under a flat user_id, invisible to other agents. Uteke Rooms let multiple AI agents share a memory space with full author attribution.
# Create a shared room
uteke room create "engineering" --description "Team decisions"
# Alice's agent stores a decision
uteke remember "We chose Redis for caching over Memcached" \
--room engineering --author alice
# Bob's agent adds context
uteke remember "Redis cluster: 3 nodes, 2 replicas each" \
--room engineering --author bob
# Any agent can recall the shared history
uteke recall "caching decision" --room engineering
Why this matters:
| Problem without Rooms | Solution with Rooms |
|---|---|
| Agent A can't see Agent B's memories | Shared space, cross-agent recall |
| Team knowledge is siloed per user | One room, multiple authors |
| No way to attribute who said what | Author on every memory |
| Multi-agent workflows need manual sync | Agents share context automatically |

๐ฆ Deployment Modes
Uteke runs the same everywhere. Pick the mode that fits your setup.
Local-first (default)
Single binary, zero infrastructure. Everything runs in-process on your machine:
curl -sSL codecora.dev/uteke/install | sh
uteke remember "first memory"
No Docker, no Python, no database server. Your data stays in ~/.codecora/uteke/. This is what most users need.
Docker / Server mode
Running Uteke as a shared service for a team, or deploying to a server? Docker keeps it simple:
docker run -d \
-p 127.0.0.1:8767:8767 \
-v uteke-data:/data \
ghcr.io/codecoradev/uteke:latest
Prefer the binary directly? Run it as a daemon:
uteke serve --host 0.0.0.0 --port 8767
Both expose the same HTTP API. Other agents and tools connect via http://your-host:8767. Rooms work across agents whether they're on the same machine or connecting remotely.

How hybrid search works:
- HNSW (usearch): finds by meaning ("deploy" matches "rollout")
- FTS5 (SQLite): finds by exact terms ("deploy" matches "deploy")

Everything runs in-process. No network. No cloud. No server required (unless you want server mode).
โ FAQ
How is Uteke different from cloud-dependent memory tools?
Many memory layers (Python-based or TypeScript-based) require cloud API keys (OpenAI/LLM) and external infrastructure (Docker, Postgres, Qdrant). Your data gets sent to a cloud LLM provider. Uteke is a single binary with zero API keys. All embeddings run locally via ONNX. Your data never leaves your machine. See comparison table.
How is Uteke different from multi-tool MCP platforms?
Some platforms offer dozens of MCP tools and multi-agent shared memory via a local engine. They're packed with integrations, but require npm, a separate runtime, and LLM API keys for embeddings. Uteke is Rust, zero dependencies, and works fully offline with local ONNX embeddings. If you want maximum integrations โ those platforms. If you want privacy, speed, zero setup, and hybrid search โ Uteke.
How is Uteke different from other single-binary memory tools?
Some single-binary tools share our philosophy: one binary, zero deps, MCP server, local-first. The key difference is search: most are FTS5-only (keyword matching). Uteke uses hybrid search (HNSW vector similarity + FTS5 + Reciprocal Rank Fusion), meaning you can search by meaning, not just exact words. Uteke also adds rooms, time-travel, graph relationships, smart decay, document engine, and batch import.
How is Uteke different from local-mode cloud tools?
Some cloud-native tools now offer a local binary mode with Ollama support. Their cloud version still needs managed infrastructure (Workers, Postgres, etc.). Uteke is one binary with zero infrastructure: no Workers, no Postgres, no cloud account. Uteke also adds rooms for multi-agent collaboration, time-travel queries, and hybrid search (vector + FTS5 + RRF fusion).
What can Uteke remember?
Anything text-based: decisions, meeting notes, code snippets, project context, personal notes, agent state. You can tag, categorize, and link memories. The --batch-dir flag lets you import entire document directories.
Does it really work offline?
Yes. The embedding model (EmbeddingGemma Q4, 768d) downloads once (~188MB) on first run. After that, zero network calls. No telemetry. If the local model fails, Uteke degrades gracefully to a no-op embedder. It never crashes and never calls a cloud API.
How fast is recall?
~45ms as a library (measured at 100โ10K memories). No network round-trip because everything is local. The LRU recall cache eliminates redundant embedding computation for repeated queries.
Can I use Uteke with my existing AI tools?
Yes. Uteke ships with an MCP server that works with Claude Code, Cursor, and Hermes. You can also use the HTTP API directly in any language. See MCP setup โ
Is it production-ready?
Uteke is at v0.13.0 with 460+ tests, CI/CD on every commit, and benchmark harness. It's used in production by the CodeCora team and other early adopters. Still in 0.x, so expect rough edges, but the core is stable.
