interest-memory — Long-term memory for AI agents

One ~50MB process instead of a Postgres + Redis + vector DB stack.

Agents forget everything between sessions. Not the model's fault — they lack a real memory layer. interest-memory is a standalone memory backend: at the end of a session it extracts interest points from the transcript, verifies and cleans them, and writes them into a local knowledge base; at the start of the next session it recalls and injects relevant context. The entire footprint: one 18MB binary + one SQLite file. The unit of memory is the interest point: semantically similar ones are merged automatically, and each one is written into the knowledge base as a wiki page by an LLM-driven agent loop — the knowledge base converges with use instead of bloating.

Selling point	Detail
Light	one ~18MB binary + one SQLite file is the whole footprint; ~17MB idle, <75MB peak (measured), runs on a Raspberry Pi
Simple	one binary + one config file is a complete service; one-command curl install, no external DB, no cloud dependency (LLM/embedding can point at local Ollama/vLLM for fully offline use)
Extract at session end	automatically extracts interest points → verifies → writes to the local knowledge base
Recall at session start	recalls relevant memories → injects into context (concise entries only, full content on demand, minimal context pollution)
Multi-agent shared	one service for many agents (Hermes / OpenCode / Claude Code / Codex etc.), with isolated, fully-shared, or selective sharing
Full audit	every structural change is written to change_log, replayable
Interest-point convergence	semantically similar interest points are auto-merged or related instead of stacked — memory converges with use instead of bloating
Archive & evolve	stale entries are marked superseded/archived (not deleted) with a replacement chain to the successor; GetByID reveals what superseded what — old knowledge is preserved without misleading
Semantic edges	the LLM classifies 5 edge kinds while writing wiki pages: related / contradicts / sequel / references / has_page; structural changes propagate within 3 hops (cascade archive, replacement substitution, contradiction closure, content sync)
Graph walk	hits are entry points into a memory graph, not isolated chunks: every result carries outlinks + backlinks (id/title/kind/weight), and search?id= jumps to a node and expands again — traverse point → neighborhood → network, beyond one-shot RAG
Evidence-backed	every entry carries evidence (web URL / turn / query); subjective preferences are never stored as facts; contradictions are closed in a loop

Quick start

One-command install (curl)

curl -fsSL https://raw.githubusercontent.com/djasdh/interest-memory/main/scripts/install.sh | bash

Auto-fetches the source → checks/installs dependencies → guides setup → optional systemd.

Configure the LLM (let your agent fetch and run it)

curl -fsSL https://raw.githubusercontent.com/djasdh/interest-memory/main/scripts/install_llm.py | python3 - --provider <provider>
# --help lists all providers; hand to your agent: it reads --help (its operating instructions) and configures itself

Pre-built binary (optional): Release v0.1.0 (linux / mac / windows)

Resource usage (measured)

Metric	Value
Binary size	~18 MB (cgo static sqlite-vec)
Idle memory	~17 MB RSS (measured)
Pipeline peak	<75 MB RSS
Initial footprint	~20 MB (binary + empty DB)
Growth	~38 MB after a week of use; mostly raw session transcripts (~71%)

session_transcripts keeps full raw text — trim externally to bound disk growth; fork.max_concurrency / verify.max_concurrency cap peak memory.

Integration

Multiple agent frameworks are supported out of the box, sharing one env set (INTEREST_BASE_URL / INTEREST_AGENT / INTEREST_TIMEOUT); a down service never blocks a session:

Agent	Form
Hermes	MemoryProvider plugin ($HERMES_HOME/plugins/interest/)
opencode	local plugin (~/.config/opencode/plugin/memory.ts)
openclaw	native plugin (<configDir>/extensions/interest-memory/)
pi	TS extension (~/.pi/agent/extensions/interest-memory/)
Claude Code	official plugin + MCP (claude --plugin-dir bridge/claudecode)
Codex	official plugin / hooks + MCP (~/.codex/hooks.json)
Reasonix	official plugin + MCP (reasonix plugin install bridge/reasonix --link)
DeepSeek Harness	Cordis plugin (dsh plugin --profile web add @djasdh/interest-memory-dsh-bridge, source bridge/dsh/)

Every bridge offers the same capabilities: session-start recall injection, session-end transcript push, and memory_search / memory_logs consumer tools. See bridge/README.md.

Architecture

internal/store/      SQLite (interest points/wiki pages/edges/claims/transcripts/change_log)
internal/vec/        sqlite-vec vector index (FTS fallback)
internal/llm/        OpenAI-compatible Chat/Embedding
internal/fork/       sliding-window split + parallel candidate extraction
internal/verify/     3-stage verification (check/claims/contradictions)
internal/wiki/       per-point agent-loop writer + related-page reconciliation
internal/recall/     recall injection + structured queries
bridge/hermes/       Hermes MemoryProvider plugin

API quick reference

Method	Path	Description
POST	/api/v1/{agent}/sessions	session-end transcript push → 202 job_id; optional kanban_board / kanban_board_name (board identity — when it hits kanban_exclude the push returns 202 + skipped and is never stored)
GET	/api/v1/{agent}/recall?query=&after=&before=&days=	recall injection (optional time filters)
GET	/api/v1/{agent}/search?query= or ?id=&top_k=	consumer query: full content + outlinks/backlinks; ?id= jumps to a node for graph walk
GET	/api/v1/{agent}/logs?limit=&offset=	change log (desc, paged)
GET	/api/v1/{agent}/interest-points	list interest points
GET	/api/v1/{agent}/wiki/pages[?type=]	list wiki pages
POST	/api/v1/{agent}/fork	manually trigger forking
GET	/api/v1/{agent}/jobs/{id}	job status
GET	/api/v1/{agent}/stats	stats
GET	/api/v1/{agent}/graph	full graph for visualization: nodes (interest points + wiki pages, medium fields) + edges (all kinds), id-collision prefixed
GET	/api/v1/{agent}/graph.html	embedded 3D viewer: dual-plane community layout, kind/status filters, node/link/plane-z sliders, search, click detail
GET	/api/health	health check

Namespaces

Each agent ({agent} path segment / INTEREST_AGENT) has an isolated namespace; cross-namespace reads are configured via namespaces:

namespaces:
  mode: isolated   # isolated (default) | all | custom
  visible_to:      # custom only: one-way visibility declarations
    codex: [opencode, pi]

Shared results are annotated with origin ([from: <agent>] on recall lines, result.agent in search/get).

Kanban board exclusion

Kanban worker sessions push their full transcripts into memory. To keep certain boards (internal projects, transient orchestration cards, …) out of the memory base, list them in interestmemory.kanban_exclude — they are dropped at the ingest boundary: not stored, not embedded, not token-accounted.

interestmemory:
  kanban_exclude: ["default", "t_90c0c7ab"]   # exclude by board name or ID

Aspect	Detail
Default	[] (empty array). Unconfigured or explicit [] behaves exactly like before: no board is excluded
What matches	The board slug/ID (e.g. default) or its display name — either hit excludes
Matching rules	Case-insensitive (Default ≈ default); entries and board identity are both whitespace-trimmed; blank entries are ignored
Where it takes effect	At the POST /sessions boundary, before storage and before the worker queue — an excluded push returns 202 + {"skipped":"kanban_board_excluded"}, persists nothing and enqueues nothing, so embedding / fork extraction / token stats can never run for it
How it is wired	The Hermes bridge attaches the board identity (HERMES_KANBAN_BOARD + display name) to worker pushes automatically, no extra setup; manual pushes can include kanban_board / kanban_board_name in the body
