Alice
The continuity layer for AI agents.
Alice is a local-first memory service that lets AI agents resume interrupted work, track open loops, recall decisions with provenance, and improve when corrected — instead of re-reading transcripts or trusting opaque summaries.
In one historical run dated 2026-07-07, it scored 79.4% on LongMemEval, a long-term-memory benchmark. That is a single-run receipt, not a repeated-run estimate or a measurement of the current release; it includes one disclosed trade-off on the abstention subset (25/30 → 22/30). The full per-question evidence, methodology, and reproduction script are committed to this repo. Open source, local-first, MIT-licensed.
Agents connect over MCP, HTTP API, or CLI. Humans stay in control: agent writes land as policy-checked commits or reviewable proposals, and a local review console is where memory gets approved, corrected, or forgotten. That review boundary is a feature, not a limitation — it is what makes the memory trustworthy enough to act on.
How Alice compares
Most agent memory tools — mem0, Zep, Letta, and similar — focus on extracting facts from conversations and retrieving them later. That solves recall, and they do it well. Alice focuses on continuity: it stores typed continuity objects (decisions, open loops, resumption briefs) alongside plain memories; source-backed answers trace to the evidence that was supplied; and writes are review-governed, so an agent cannot silently promote a bad extraction into durable truth. Explicit commits may legitimately have no source reference. If you mainly need conversational fact recall, those tools are solid choices. If your agents need to resume work, honor past decisions, and explain why they believe something, that is what Alice is built for.
Alice is a layer, not a lock-in: it runs happily alongside other memory tools, and plenty of stacks will want both — a fact-extraction memory for conversational recall and Alice for governed continuity.
What Alice stores
- Memories — typed, revisioned facts with trust classification and, when evidence was supplied, provenance links to that source evidence.
- Decisions — what was decided, when, and what superseded it.
- Open loops — blockers, waiting-fors, and follow-ups that agents can query, create, and close.
- Resumption briefs — "here is where work stopped, and what should happen next" for a project or thread.
- Provenance and audit — source-backed memories identify their supplied sources; reviews and corrections preserve their audit chain. Explicit commits may legitimately have no source reference.
Corrections are first-class: when a memory is corrected or superseded, future recall reflects the correction and the explanation chain shows why.
Quickstart
The fastest path is the packaged runtime from PyPI — Python 3.12+ and nothing else, no Docker, Node, or Postgres. It serves the eleven core MCP tools against a single local SQLite file:
uvx alice-memory mcp --data-dir ~/.alice
# or: pip install alice-memory && alice-memory mcp --data-dir ~/.alice
MCP client config (Claude Desktop, IDEs) — note there is no DATABASE_URL:
{
"mcpServers": {
"alice": {
"command": "uvx",
"args": ["alice-memory", "mcp", "--data-dir", "/ABSOLUTE/PATH/TO/.alice"]
}
}
}
SQLite mode is the trial and single-agent path: it serves the eleven core tools for one user, and memory review happens through alice_memory_review / alice_memory_correct instead of the web console. Boundaries are listed in known limitations.
Install note: the PyPI package is
alice-memory. The namealice-coreon PyPI belongs to an unrelated project.
Full stack (Postgres + review console)
For the full experience — Postgres/pgvector, the web review console, and core memory scheduler workflows — run from a repo checkout. Requirements: Python 3.12+, Node 20+, pnpm, Docker, Git.
git clone https://github.com/samrusani/AliceBot.git
cd AliceBot
make setup
make migrate
make doctor
make dev
make setupcreates.envfiles from checked-in examples and installs Python and web dependencies.make migratestarts local services (Postgres via Docker) and runs database migrations.make doctorruns readiness checks and applies safe fixes.make devruns the API on port 8000 and the web review console on port 3000.
Open the review console at http://localhost:3000/vnext. The detailed walkthrough — demo data, smoke checks, first memory — is in the alpha quickstart.
Connect an agent
MCP
Point any MCP-capable agent or IDE at the Alice server. For the packaged SQLite runtime, use the uvx config from the Quickstart above. For the full Postgres stack from a checkout:
{
"mcpServers": {
"alice": {
"command": "/ABSOLUTE/PATH/TO/AliceBot/.venv/bin/python",
"args": ["-m", "alicebot_api.mcp_server"],
"cwd": "/ABSOLUTE/PATH/TO/AliceBot",
"env": {
"DATABASE_URL": "postgresql://alicebot_app:alicebot_app@localhost:5432/alicebot",
"ALICEBOT_AUTH_USER_ID": "00000000-0000-0000-0000-000000000001"
}
}
}
}
The core MCP surface is eleven tools:
alice_capture— submit new information as source-backed, reviewable memoryalice_memory_commit— write an explicit "remember this" memory through policy: committed, confirmation-required, review-required, or rejectedalice_recall— search memory (full-text plus vector, fused ranking; hard-scopable by thread, task, project, person, time, and memory type)alice_resume— resumption brief for a project or threadalice_context_pack— project/person/time-scoped context for a task, with a bounded unique-content budget and a complete serialized-size estimatealice_open_loops— list and manage open loopsalice_recent_decisions— recent decision logalice_memory_review— inspect items pending reviewalice_memory_correct— propose a correction to an existing memoryalice_memory_manage— confirm, undo, or forget a committed memory, audit trail intactalice_explain— provenance and trust explanation for a memory
Calling directly from a human client (Claude Desktop, an IDE)? alice_memory_commit needs only title and canonical_text — no identity fields. Agent integrations declare agent_id and agent_type; see agent integration.
The write verbs follow one contract — outcomes, audit guarantees, and honest boundaries per verb are documented in the Memory Operations Protocol. Removed backing services no longer have MCP tools. Retained long-tail memory tools require ALICE_MCP_LEGACY_TOOLS=1; exactly alice_task_brief, alice_task_brief_show, and alice_task_brief_compare additionally require ALICE_LEGACY_SURFACES=1. All legacy tools require a deliberately keyless local-operator deployment; a server bound with ALICE_AGENT_API_KEY exposes only the policy-complete core surface.
Custom agents calling the HTTP API authenticate with per-agent API keys. See agent integration.
Embeddings
Semantic search works with any OpenAI-compatible embeddings endpoint — Ollama, LM Studio, or OpenAI:
ALICE_EMBEDDINGS_BASE_URL=http://localhost:11434/v1
ALICE_EMBEDDINGS_MODEL=nomic-embed-text
ALICE_EMBEDDINGS_API_KEY= # only if the endpoint requires one
Search fuses Postgres full-text results with pgvector 0.8+ (iterative HNSW) similarity using reciprocal-rank fusion. If no embedding endpoint is configured, search degrades to full-text only and says so explicitly in the retrieval trace.
Status
v0.13.1 is the latest published release and remains the install, checksum,
and release-note baseline (the v0.13.0 tag was never published;
superseded). Its tag, release record, and published artifacts
are immutable.
v0.12.0 shipped the Phase 3 structural refactor with Structure only. Zero
behavior change. It splits oversized HTTP, store, contract, MCP, and CLI
modules behind stable imports and entrypoints.
The published v0.11.0 runtime narrows the default product to the agent
interface and retrieval/memory core.
Alice is a public-alpha, pre-1.0 project.
What that means in practice:
- Local-first, single-user. One operator, one machine (or one headless server reached over SSH).
- Review-governed writes. Agents propose or commit through policy; outcomes are commit, confirm, review, or reject. The review console is the trust boundary for durable memory.
- No hosted service. There is no cloud offering yet; you run Alice yourself.
- No channels or bundled chat runtime. Telegram, hosted administration,
chief-of-staff/chat/model-pack features, and the public
/v0/responseschat endpoint are not part of the current product. Retained/v1/runtime/invokestill uses internal durable response-job/provider machinery. - No managed OAuth or automatic polling. Temporary manual-token Gmail and
Calendar compatibility is unmounted by default behind
ALICE_LEGACY_SURFACES=1; Alice does not provide managed consent or syncing. - No automatic capture from arbitrary conversation. Durable memory comes from explicit commits, reviewable proposals, or captured sources, never from silent transcript mining.
- No OCR or transcription execution. Alice accepts text extracted by an external tool; it does not run OCR or transcription models.
