oubli 0.2.1

Fractal memory system for Claude Code

Oubli

Oubli: French for "forgetting." (Also a West African fruit so sweet it makes babies forget their mother's milk.)

A memory system that never forgets. Persistent fractal memory for Claude Code.

Features

• Core Memory - Essential facts about you (~2K tokens), loaded in every conversation
• Persistent Storage - Memories survive across sessions, stored locally in LanceDB
• Smart Import - Import your Claude.ai memory export with one command
• Auto-Save - Saves memories at session end and before context compaction
• Auto-Deduplication - Duplicate memories are automatically detected and merged (85% similarity threshold)
• Fractal Synthesis - Automatically consolidates raw memories into higher-level insights via /synthesize
• Auto-Synthesis - Synthesis triggers automatically when unsynthesized memories exceed threshold
• Proactive Memory - Claude searches and saves automatically, no prompting needed
• Immediate Core Memory Updates - Family, work, and identity changes update Core Memory instantly
• Quiet Operation - Memory operations happen silently in the background
• Local-First - No external services, no API keys, your data stays on your machine

Installation

pip install oubli
oubli setup

Then restart Claude Code.

Requirements

• Python 3.10+
• Claude Code CLI installed

Uninstall

oubli uninstall
pip uninstall oubli

What Gets Installed

Component	Location	Description
MCP Server	claude mcp	15 memory tools (save, search, synthesize, etc.)
Hooks	~/.claude/settings.json	UserPromptSubmit, PreCompact, Stop
Slash Commands	~/.claude/commands/	/clear-memories, /synthesize
Instructions	~/.claude/CLAUDE.md	How Claude should use the memory system
Data	~/.oubli/	LanceDB database + Core Memory file

Usage

After installation, restart Claude Code. Your Core Memory will be automatically loaded in every conversation.

Import Existing Memories

Paste your Claude.ai memory export and ask:

"Import this into my memory"

Claude will parse it into structured memories and optionally create your Core Memory.

Natural Interaction

Just talk naturally:

• "Remember that I prefer TypeScript over JavaScript"
• "What do you know about my work?"
• "I no longer work at Spotify, update your memory"

Slash Commands

• /clear-memories - Clear all memories (requires confirmation)
• /synthesize - Run full synthesis workflow: merge duplicates, create insights, update Core Memory

How It Works

           ┌─────────────────────────────────────────┐
           │            CORE MEMORY                  │

           └─────────────────────┬───────────────────┘
                                 │ (distilled from)
                                 ▼
Level 1+   ○ "Deeply appreciates jazz guitar, especially fusion"
(insights)  ╱╲
           ╱  ╲
Level 0   ○ ○ ○ ○  Raw memories from conversations
(raw)

• Core Memory: Always loaded, contains the most important stable facts
• Level 0: Raw memories from conversations with full context
• Level 1+: Synthesized insights from multiple raw memories

Data Storage

All data is stored locally in ~/.oubli/:

• memories.lance/ - LanceDB database
• core_memory.md - Your Core Memory (human-readable, editable)

MCP Tools

Oubli provides 15 MCP tools for memory operations:

Tool	Description
memory_save	Save a new memory (auto-deduplicates)
memory_search	Search memories by BM25 full-text search
memory_get	Get full details including conversation text
memory_get_parents	Drill down from synthesis to source memories
memory_list	List memories by level
memory_stats	Get memory statistics
memory_update	Update an existing memory
memory_delete	Delete a memory
memory_import	Bulk import memories
memory_synthesis_needed	Check if synthesis should run
memory_prepare_synthesis	Merge duplicates and get groups for synthesis
memory_synthesize	Create Level 1+ insight from raw memories
memory_dedupe	Manual duplicate cleanup
core_memory_get	Get Core Memory content
core_memory_save	Save Core Memory content

Development

# Clone and install in development mode
git clone https://github.com/dremok/oubli.git
cd oubli
pip install -e .
oubli setup

# Run tests
python -c "from oubli.storage import MemoryStore; store = MemoryStore(); print(store.get_stats())"

# Check MCP tools
python -c "from oubli.mcp_server import mcp; print([t.name for t in mcp._tool_manager._tools.values()])"
