The second brain
for you and your agents.

Human-agent collaboration requires trust.
Trust is built over time through shared memory and portable context —
so every human and every agent can move from the same source of truth.

Agent Chat Workspace

Main-agent planning with memory-aware context and inline recall.

Agent Orchestration

Scoped subagent delegation, run inspection, and runtime telemetry.

Usage Analytics

From prompts to trusted operations

LittleGuy is the memory control plane for human-agent systems: one shared context layer where goals, decisions, and execution history stay portable across tools and time.

Without a control plane

Context fragments across chats, tools, and teammates

  • Agents repeat questions because session memory resets
  • Decisions get buried in message history and docs
  • Delegated work loses provenance and constraints
  • Teams cannot audit why an agent made a choice
With LittleGuy

A durable operating memory for humans and agents

  • Human intent stays connected to execution outcomes
  • Main agent coordinates subagents with scoped context
  • Important events are classified and queryable later
  • Trust grows because context and decisions stay inspectable

Operating philosophy

Shared memory over isolated prompts

Every conversation should inherit decisions, commitments, and prior context. No more starting from zero for each agent or surface.

Trust through explicit boundaries

Scope is not optional. Agents get only the tools, memory slices, and permissions needed for the task at hand.

Reliability through continuous classification

Captured context is typed, scored, and connected as it lands so retrieval stays high-signal as your system grows.

Fast execution, durable context

Delegated work can be parallel and short-lived while memory remains durable across web, desktop, and mobile clients.

Human(s)

Define objectives, constraints, and acceptance criteria. Humans decide what matters and approve what becomes durable memory.

Main Agent

Plans strategy, decomposes work, routes tasks, and enforces policy. It is the orchestrator, not the single executor.

Subagents

Specialized workers with tight scopes. They execute delegated tasks, return evidence, and commit only what is approved.

Execution loop

The control plane keeps capture, delegation, and memory commit in one reliable loop, so teams can move quickly without losing traceability.

1) Human sets goal, constraints, and quality bar
2) Main agent scopes work and creates delegated tasks
3) Subagents execute with limited memory + tool surface
4) Results are classified (decision, task, knowledge, risk)
5) Approved context is committed back to shared memory

Trust guards

Human-agent trust is a systems property. These controls keep context relevant, constrained, and auditable at every step.

Policy-aware delegation with explicit tool boundaries

Built for builders and teams running agentic systems

LittleGuy is where human intent, agent execution, and shared organizational memory meet. One control plane. Multiple teams. Many agents.

Engineering + Product

Persist architecture decisions, incident context, and implementation constraints so main agents and coding subagents execute from the same baseline.

  • Spec-to-code continuity
  • Decision provenance
  • Scoped delegation for PR tasks

Research + GTM

Capture interview insights, market signals, and messaging hypotheses as typed memory, then reuse them across strategy, content, and sales workflows.

  • Reusable research memory
  • Cross-functional context sharing
  • Higher-signal briefing

Ops + Customer Teams

Turn tickets, runbooks, and postmortems into durable operational memory so response agents can act quickly without repeating discovery work.

  • Faster handoffs
  • Runbook-aware agent responses
  • Reduced context loss during escalation

Security + Governance

Apply project and role boundaries to memory recall and tool access. Keep delegation observable while preserving least-privilege behavior.

  • Policy-aware retrieval
  • Auditable memory updates
  • Safer multi-agent execution

The Memory Control Plane for agentic teams

Beyond chat history. Beyond personal notes. LittleGuy gives teams a shared, governed memory layer for multi-agent execution.

MCP-native shared memory

Connect Claude, ChatGPT MCP, Gemini, and internal agents to one memory plane. Query context, commit outcomes, and preserve continuity across every tool.

Main + subagent delegation

Main agents orchestrate strategy while subagents execute tightly scoped jobs with bounded tools and contextual slices.

Main Agent: plan + route
|
Subagent A: research scope
Subagent B: implementation scope
Subagent C: validation scope

Skills + tool surfaces

Attach domain skills to agents, gate tools by responsibility, and keep capabilities explicit so delegation remains auditable.

Token and context management

Keep prompts lean by routing memory retrieval: fast paths for known patterns, deeper recall only when confidence or novelty requires it.

Deterministic recall for frequent intents
Cached execution for repeated workflows
Agentic retrieval only for complex or novel asks
Memory filters by source, score, and recency

Classification + scoping

Every capture is typed and connected so agents retrieve usable context instead of raw logs. Scope follows project, role, and task intent.

Classify: decision, task, knowledge, event
Relate: people, projects, commitments
Scope: project-tag + role boundaries
Decay: stale context loses weight

One memory across web, desktop, and mobile

Capture on mobile, orchestrate on desktop, monitor on web, and execute through MCP-enabled agents. Same memory graph, same context lineage, everywhere.

Control plane internals

Architecture for durable human-agent trust

LittleGuy is designed as a Memory Control Plane: structured memory, scoped execution, and portable context across web, desktop, mobile, and MCP clients.

Graph + Vector
Memory substrate

Neo4j relationships + pgvector semantic recall in a dual-store architecture.

26 node types
Typed memory

Decisions, tasks, people, events, documents, and more for higher-precision retrieval.

OAuth + PKCE
MCP auth

Token issuance, refresh, and revocation for secure agent-to-memory connectivity.

Latency aware
Runtime discipline

Deterministic, cached, and agentic retrieval modes keep token use and latency under control.

Async memory lifecycle

4 workers
MEMORY_EXTRACT

Parses raw capture into structured objects: entities, facts, commitments, and decisions.

CLASSIFY

Assigns node type and confidence so retrieval can route to relevant context classes.

EDGE_INFER

Connects people, projects, and knowledge over time to maintain relationship-aware recall.

TEMPORAL_DECAY

Reduces stale relevance unless reinforced, keeping memory fresh without manual cleanup.

Typed memory schema

Governance primitives
Delegation + scoping

Main agents delegate tasks to subagents with explicit boundaries for memory and tools, reducing accidental context bleed.

Skill-aware execution

Skills and tool surfaces align to roles so each agent uses the right capabilities for the right class of work.

Token management

Recall policies prioritize high-signal context first, then expand only when required by novelty or ambiguity.

MCP as the trust transport layer

OAuth 2.0 + PKCE secures client connectivity while scoped tokens, revocation, and policy-aware tool surfaces keep memory access intentional. This is the foundation for reliable collaboration between humans, main agents, and delegated subagents.
