Project description

MemoryBrain

===========

Long-term memory library for AI assistants, chatbots, and autonomous agents.
Stores memories in a local SQLite database with intelligent ranked retrieval.

Requirements
------------
- Python 3.10 or newer
- No third-party runtime dependencies

Installation
------------
pip install memorybrain

Or install from source:

pip install .

Quick Start
-----------
from memorybrain import MemoryBrain

brain = MemoryBrain()

brain.remember(
"User likes Flutter development",
tags=["flutter", "programming"],
importance=10,
)

results = brain.recall("What framework does the user like?")
for memory in results:
print(memory.text)

matches = brain.search("Flutter")
print(matches)

print(brain.stats())

API Overview
------------
remember(text, tags=None, importance=5)
Store a new memory. Returns a Memory object.

recall(query, limit=10)
Retrieve memories ranked for a natural-language query.

search(query, limit=10)
Search memories by keyword relevance.

forget(memory_id)
Delete a memory by ID. Returns True if deleted.

export("memories.json")
Export all memories to a JSON file.

import_file("memories.json")
Import memories from JSON (upsert by ID).

stats()
Return statistics:
- total_memories
- most_common_tags (list of {tag, count})
- database_size_bytes

Custom Database Path
--------------------
brain = MemoryBrain(db_path="./data/my_memories.db")

Default location: ~/.memorybrain/memories.db

Build and Publish to PyPI
-------------------------
Install build tools:

pip install wheel twine build

Build source distribution and wheel:

python setup.py sdist bdist_wheel

Or using the modern build frontend:

python -m build

Validate packages:

twine check dist/*

Upload to PyPI (requires PyPI account and API token):

twine upload dist/*

Test upload to TestPyPI first:

twine upload --repository testpypi dist/*
