A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
เปิดOn Monday you spend an hour with Claude working out why the login system leaks memory, and you decide to switch libraries. On Friday you open a new chat and ask "why did we drop Passport again?"
It has no idea. The conversation is gone, and so is the reasoning.
The same thing happens with everything you tell an AI: your sister's birthday, the bug you already fixed, the reason a setting is the way it is. Every new chat starts from zero.
Engram is a memory that outlasts the chat. It saves your notes, files and conversations, and when you ask a question later, it finds the right one, even if you phrase it completely differently.
Two ordinary notes go in:
notes/decisions.md We switched from Passport to Lucia on March 3 because
Passport sessions kept leaking memory under load.
notes/personal.md My sister Maya's birthday is June 14. She loves anything
with sunflowers.
engram mine notes --wing life
Days later, ask in your own words. None of these questions share a sentence with the notes:
$ engram search "why did we change the auth library"
1 life/notes We switched from Passport to Lucia on March 3 because
Passport sessions kept leaking memory under load.
$ engram search "gift idea for Maya"
1 life/notes My sister Maya's birthday is June 14. She loves anything
with sunflowers.
Hook it up to Claude and it does this by itself: Claude looks things up in Engram when it needs them, and Engram saves your Claude Code sessions automatically.
You need Python 3.9 or newer (3.11 to 3.14 is best). Check with python3 --version.
1. Install
pip install engram-chateau
On PyPI the package is called
engram-chateau, but the command you type is justengram. (A different, unrelated package already owns the nameengram.)
2. Give it something to remember
engram mine ~/Documents/notes --wing notes # any folder of notes, docs or code
The first run downloads a small language model (about 80 MB) that lets Engram understand meaning. After that, everything works offline.
3. Ask it something
engram search "what did I decide about the database"
That's all you need to try it.
Engram works with any app that speaks MCP, the standard way AI apps plug in tools. One command adds it:
engram connect cursor # or: claude-desktop, windsurf, vscode, gemini, codex, zed, lm-studio
engram connect all # every supported app on this computer
engram connect # list them, with ✓ next to the ones you have
It adds Engram to that app's settings (keeping everything else, with a .bak backup) and tells you how to restart the app. Run it again any time; it changes nothing the second time.
Every app then has 31 engram_* tools: recall, search, remember, correct an outdated memory, link a conclusion to its evidence, explain why a memory says what it says, a topic's history, a knowledge graph of people and facts, and more. On connect, Engram also tells the AI how to use them: check memory before answering anything that depends on past work, save decisions, and correct rather than contradict. (Apps decide whether to pass that guidance to the model; most current ones do.) Ask "remember that we use tabs in this repo", "what did we decide about auth?" or "we moved to PostgreSQL, update that".
Claude Code gets the most: memory that works without being asked.
engram connect claude-code # prints the one-line `claude mcp add` command
engram install-hooks --apply # then restart Claude Code
install-hooks adds three Claude Code hooks to ~/.claude/settings.json (your existing settings are kept, with a backup):
Preview what auto-recall would hand Claude with engram recall "your message". Run engram install-hooks without --apply to see the settings instead of applying them, or add --no-recall to skip auto-recall.
Any other MCP app: point it at the command engram-mcp (or python -m engram.mcp_server). Engram is also listed in the official MCP registry as io.github.TushaeBXN/engram.
Apps that don't speak MCP (Open WebUI, n8n, your own scripts) can use Engram over a small local web API:
engram serve # http://127.0.0.1:7742, the same tools and rules as MCP
Point the app at http://127.0.0.1:7742/openapi.json; every tool is described there. Or call it directly:
curl -s localhost:7742/v1/tools/engram_recall -H 'Content-Type: application/json' \
-d '{"message": "why did we drop Passport?"}'
Memories are private, so it is strict by default. It listens on localhost only, and refuses requests that look like they come from a web page or through a proxy. To reach it from another machine, use engram serve --host 0.0.0.0: that always requires a token (created on first use in ~/.engram/server/token, never printed), sent as Authorization: Bearer <token>. engram serve --token requires one even on localhost. No CORS headers are ever sent, so a web page can't talk to it.
Teach any coding agent to use it. skills/engram/SKILL.md is a ready-made agent skill: when to recall, save and correct, and how to explain a conclusion. Install it with npx skills add TushaeBXN/engram (or copy the file).
uv tool install engram-chateau # or: pipx install engram-chateau
engram init ~/myproject # guided setup: your AI's identity, a default wing, then saves the project
Both put engram and engram-mcp on your PATH without touching your system Python.
🧑💻 Developers using Claude Code. Engram quietly saves the files Claude touches and the conversations behind them. Months later, "why is the retry limit 7?" brings back the actual discussion, not a guess.
🤖 People building an AI companion or agent. Give your bot a memory of its own: what it has learned about you, a diary, and a knowledge graph of people and facts ("Kai works on Orion, since June"). It all runs offline in a few lines of Python. Engram started life as exactly this, the memory of a personal companion app.
📚 Writers, researchers and note-takers. Point it at a folder of notes, an Obsidian vault, or Notion or Linear exports, and search across all of it by meaning: "that idea I had about pricing tiers".
~/.engram/). No account, no cloud, no API key, no tracking.INV-20931), and understands time: "two weeks ago", "in June", "on May 8".redact_secrets and API keys, tokens and passwords are blanked out before anything is written to disk.Engram files memories the way you'd organise a big house: one wing per person or project, a room per topic, a hall per kind of memory, and inside, drawers holding the original text.
Wing – a person or project ("myapp", "life")
└── Room – a topic ("auth-migration")
└── Hall – the kind of memory (facts, events, discoveries, preferences, advice)
└── Drawer – your original text, word for word
You don't have to manage any of this; Engram sorts things as it saves them. When you search, it weighs several clues together:
At the start of a session, Engram can also hand the AI a small "wake-up" note (who it is plus key facts: pinned ones first, then the newest, about 120 tokens by default), so it never starts completely cold.
In March you note that the app stores everything in SQLite. In April you move to PostgreSQL. Most memory tools now hold two contradicting notes and return whichever matches the question best.
In Engram, you (or Claude, or your agent) record the change once:
engram correct file-05aa607a "We migrated the app from SQLite to PostgreSQL on April 9" --reason "SQLite locked under concurrent writes"
From then on, search puts the current answer first and keeps the old one, clearly labelled, right below it:
$ engram search "which database does the app use"
1 c6e0b7b4 [current, replaces file-05aa607a] We migrated the app from SQLite to PostgreSQL on April 9…
2 file-05aa607a [outdated → c6e0b7b4] Decision: the app stores everything in SQLite because…
engram history file-05aa607a shows the whole story: what it said, what replaced it, when, and why. Nothing is ever silently deleted. Old evidence stays searchable, and a mistaken correction can be undone with engram supersede <id> --undo.
Engram never decides by itself that one note contradicts another. Deciding what is true is the job of whoever is using it. When Claude saves a memory, Engram points out existing memories it might update, and Claude decides.
A memory can say what it rests on and where it came from, so a conclusion never floats free of its evidence:
engram source 903294e5 primary --ref "U.S. Const. art. I, § 2" # where a memory came from
engram link c9422f65 based_on 903294e5 --reason "constitutional text"
engram link c9422f65 derived_from 2da14213 # also: contradicts, supersedes
Sources are user (you said it), primary (an original document, law, ruling or dataset), secondary (reporting or analysis), tool (a search or program result) and inference (an AI's own conclusion). Inferences stay labelled as inferences.
engram why <id> explains any memory: its source and date, whether it is a record or an inference, the evidence behind it, whether that evidence has since been corrected or disputed, earlier versions and their evidence, and, with --query, why search ranked it:
$ engram why c9422f65
c9422f65-… amy/views 2026-10-20
My view: population apportionment is the baseline; the 2025 map changes the state's representation.

Report: the legislature adopted a new map in 2025.
Needs review
• evidence 2da14213 was corrected (current version: 914e0cb2); check whether this still holds
engram check lists everything like that across your memory: conclusions whose evidence was corrected or disputed, inferences with no evidence, conflicts nobody has settled, links to deleted memories. It changes nothing. When a position is revised, the old one keeps the evidence it had, so you can always see what the earlier view rested on and what supports the new one.
Backups. engram export backup.json.gz puts every memory, correction, knowledge-graph fact and diary into one file. engram import backup.json.gz restores it on another computer, after checking the whole file first: if anything is wrong, nothing is changed. The format is documented in docs/backup-format.md.
Researchers test AI memory with two public benchmarks. Each gives the system long chat histories and asks questions whose answers are buried somewhere inside. The score is how often the system finds the right conversation.
In plain terms: ask Engram 500 questions about months of chat history, and for 494 of them the right conversation is in its top 5 results. It gets there with a small model that runs on a laptop, no LLM and no API. These tests measure finding the right conversation. They don't measure whether corrections, evidence links or recall notes make an AI more accurate; benchmarks/trust_eval.py checks those, and the results are listed below.
Does it keep memory trustworthy? Those tests don't cover corrections, the notes handed to a model, or crashes, so benchmarks/trust_eval.py checks them. On its own (author-written, deliberately small) scenarios, in the current version:
Auto-recall trades some answers for silence and small notes; the full table, what it doesn't show, and how to run it yourself are there. Nothing here shows that it makes an AI more accurate end to end; that hasn't been tested.
There are several good memory tools. Here's an honest guide.
from engram.agents import AgentDiary
from engram.backends import get_backend
from engram.chateau import Chateau
from engram.knowledge_graph import KnowledgeGraph
from engram.searcher import Searcher
memory = Chateau() # your memory folder (~/.engram/chateau)
searcher = Searcher(get_backend("chromadb"), memory)
for hit in searcher.search("what music does Maya like", n=5):
print(hit["text"], hit["final_score"])
AgentDiary("my-assistant").write("Helped plan the week") # an agent's diary
KnowledgeGraph().add(subject="Maya", predicate="likes", obj="jazz") # facts about people and things
These calls are pinned by tests/test_public_api.py, so apps built on them keep working across releases. For the full default search (exact-word index included), build the backend with engram.backends.backend_from_config(engram.config.load_config()).

Forgetting is for things that should never have been saved. A memory it replaced becomes current again, memories that rested on it lose that evidence (engram check lists any left with nothing behind them), and earlier exports still contain it.

Everything works out of the box. If you want to tweak things, settings live in ~/.engram/config.json. Every key is optional, and the defaults are the benchmarked setup.
ENGRAM_VECTOR_BACKEND=sqlitevec engram … switches the backend for one run. An embedding server works with the default chromadb backend; each server and model keeps its own index, so switching back needs no reindex and your memories are never changed. ~/.engram/identity.txt holds the short identity that starts each wake-up note.

Search indexes are rebuilt during the import.engram-mcp, give it the full path from which engram-mcp.pip install --force-reinstall --no-cache-dir chromadb, or set "vector_backend": "sqlitevec", which needs no compiled parts. Then run engram mine again, because each backend keeps its own index.sqlitevec, which matches words rather than meaning.

The reranker found nothing that really answers that question; try a more specific one.A compact text form any LLM can read without a decoder. It's used only for the short context Engram loads into a model; your drawers always keep the original text. ES drops filler words, saving about 1.6× on prose and 1.1× on code.

engram ui opens a local notes app at http://127.0.0.1:7741, with a graph of linked notes, tags, pinned notes, a daily journal and Markdown editing. It keeps its notes in your browser for now, and doesn't yet show the memories in ~/.engram/; use engram search or the MCP tools for those.
engram-chateau[faiss], [sqlitevec], [viz] (graph pictures) or [all].engram answer.Internet use: none, apart from two one-time downloads. The embedding model (about 80 MB) downloads the first time you save or search. The optional reranker (90 MB) downloads only if you run engram setup-reranker. Your memories never leave your machine.
