Memanto - Memory that AI Agents Love!

---

What Is MEMANTO?

MEMANTO is a memory agent. It remembers, recalls, and answers — so your agents can achieve long-term goals and avoid confusion.

Most memory tools today are passive infrastructure: agents have to query them, parse the results, and figure out what to do next. MEMANTO is built differently. It's an active memory agent designed from the gaps agents themselves named when asked about their memory — three operations (remember, recall, answer) that give your agents persistent context across sessions, with state-of-the-art retrieval and zero ingestion latency.

"My memory exists as a static snapshot injected into context — useful, but fundamentally passive. I can't query it, update it mid-conversation, express confidence levels, or distinguish between 'I know this' versus 'I was told this once.'"

— A representative model reply that became MEMANTO's design brief.

We unpacked that into six concrete gaps and built MEMANTO to solve all six.

The Six Gaps

#	Gap	What MEMANTO does about it
1	Static injection — memory arrives as a blob, not queryable by relevance	Queryable, not injectable
2	No temporal decay — a preference from 6 months ago weighs the same as yesterday's deadline	Versioning, recency signals, temporal queries
3	No provenance — can't tell explicit facts from inferred patterns or outdated info	Confidence + provenance metadata on every memory
4	Flat memory — episodic, semantic, and procedural all collapsed to one layer	Typed and hierarchical — 13 built-in memory categories
5	No writeback — contradictions silently coexist	Conflict detection, explicit versioning, no silent overwrites
6	Indexing delay — mandatory LLM extraction, graph construction bottleneck	Zero-overhead ingestion, available at write time

Why MEMANTO Performs

MEMANTO is built for teams that want SOTA agent memory without graph-heavy complexity. It pairs a typed semantic memory schema with Moorcheh's information-theoretic retrieval engine — a no-indexing semantic database that delivers exact search, sub-90ms retrieval, and zero ingestion delay.

• State-of-the-art benchmarks: 89.8% on LongMemEval and 87.1% on LoCoMo — outperforming Mem0, Mem0g, Zep, and Letta on both. Public datasets on Hugging Face.
• Three primitives, not two: remember, recall, and answer — LLM-grounded responses generated directly from your agent's memory, with no extra API key.
• Zero ingestion latency: No indexing wait, no LLM extraction tax at write time. Memories are searchable the instant they're stored.
• Zero idle cost: Serverless architecture scales to zero when not in use.
• Single-query retrieval: One call. No multi-stage pipelines, no graph schema to maintain, no rerankers to wire up.
• Typed semantic memory: 13 built-in memory categories — instruction, fact, decision, goal, preference, relationship, and more — for cleaner retrieval and contradiction detection.

🏗️ Architecture

📺 Setup & Demo

🚀 MEMANTO CLI

MEMANTO comes with a powerful, developer-friendly Command Line Interface. You can manage your agent's memories completely from your terminal—no local server required!

You need a Moorcheh API key to use MEMANTO. Create one in the Moorcheh Dashboard.

MEMANTO has native LLM access, so you don't need a separate external model API key for common memory workflows.

1. Install & Configure

pip install memanto

# Setup your environment (prompts for your Moorcheh API key)
memanto

2. Test Agent Memories

# Create and auto-activate an agent session
memanto agent create customer-support

# Store memories with specific semantic types
memanto remember "The user prefers dark mode for the dashboard."
memanto remember "User's timezone is PST."

# Instantly recall relevant context
memanto recall "What mode does the user like?"

# Get grounded AI answers using built-in RAG
memanto answer "Based on the memory, what should the theme be set to?"

Supported Memory Types

instruction, fact, decision, goal, commitment, preference, relationship, context, event, learning, observation, artifact, error

Use memory types to categorize what you store so retrieval is cleaner and more controllable:

• Save with a specific type: memanto remember "User prefers concise answers" --type preference
• Filter by type when searching: memanto recall "user communication style" --type preference

🎯 REST API Endpoints

For programmatic access, MEMANTO exposes a clean, session-based REST API.

Important: MEMANTO does not have a hosted API server yet. To use these endpoints, run your own local server first:

cd memanto

# Start server
memanto serve

# Or run with Docker
docker-compose up -d

By default, call the endpoints on your local server (for example: "http://127.0.0.1:8000").

Agent Management

• POST /api/v2/agents - Create a new agent namespace
• GET /api/v2/agents - List all available agents
• GET /api/v2/agents/{agent_id} - Get metadata for a specific agent
• DELETE /api/v2/agents/{agent_id} - Delete local agent metadata (?delete-backup-too=true also deletes Moorcheh namespace backup)

Session Management

• POST /api/v2/agents/{agent_id}/activate - Start a session (returns a 6-hour JWT session_token)
• POST /api/v2/agents/{agent_id}/deactivate - Manually end a session
• GET /api/v2/agents/{agent_id}/status - Check active session status for an agent

Memory Operations

• POST /api/v2/agents/{agent_id}/remember - Store a new memory into the agent's semantic database
• POST /api/v2/agents/{agent_id}/batch-remember - Batch-store up to 100 memories in one request
• POST /api/v2/agents/{agent_id}/upload-file - Upload a file (.pdf, .docx, .xlsx, .json, .txt, .csv, .md) — content is chunked and made searchable
• POST /api/v2/agents/{agent_id}/recall - Run an exact semantic search against the agent's memories
• POST /api/v2/agents/{agent_id}/answer - Generate a grounded RAG answer based on the agent's memories

Authentication Required:

• Server-side MOORCHEH_API_KEY must be configured in MEMANTO
• X-Session-Token: {session_token} header (for session-scoped and memory operations)
