Agent sends memory

Your AI agent stores context, facts, and preferences to MEMANTO via CLI or API. A single command is all it takes.

Origin Story

Identifying the gaps in
AI agent memory

When asked what causes agent memory to fail, Claude pointed to passive, static context. We unpacked that insight into six core challenges that MEMANTO was specifically engineered to solve.

Representative model reply
“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.’

Six gaps we designed around

Hover or tap a row — the diagram highlights the same theme.

Static injection

Memory arrives as a blob injected into context — can't query by relevance or filter by the current task.

No temporal decay

No provenance

Flat memory

No writeback

No scoping

Why agents love MEMANTO

Six principles. Zero compromises. Built from the failure modes of every system that came before.

6 design principles

D1

Queryable, not injectable

Agents query memory by relevance to the current task — not a static blob injected at conversation start.

D2

Temporally aware with decay

D3

Confidence & provenance

D4

Typed & hierarchical

D5

Contradiction aware

D6

Zero overhead ingestion

MemantoClaw

Persistent, long-horizon memory for NemoClaw — bringing full MEMANTO memory capabilities natively into your agentic workflows.

MemAntoClaw preview
  • Built-in MEMANTO memory layer on NemoClaw agents
  • Semantic retrieval across sessions with zero-cost ingestion
  • Agentic calls powered by Moorcheh's native LLM — no extra API keys needed
  • Open-source and self-hostable
Comparison

Memanto vs the field

Most memory layers stop at remember + recall. Memanto adds answer — LLM-grounded responses directly from your agent's memory, with no extra API keys.
