Documentation

• Technical Whitepaper - Full specification and theory

What is AIF-BIN?

A file format specification with two versions:

• AIMF (.aimf) - AI Memory Format, v1 JSON encoding for simplicity
• AIF-BIN (.aif-bin) - AI Formatted - Binary, v2 binary encoding for performance

A single .aimf or .aif-bin file contains:

• Original document — The source file preserved
• Extracted content — Text parsed into searchable chunks
• Metadata — Title, timestamps, checksums

This is the free, open source implementation. For semantic search, batch processing, see AIF-BIN Pro.

---

Format Versions

This repository contains both format versions:

Version	Extension	File	Full Name	Format
v1	.aimf	aifbin_v1.py	AI Memory Format	JSON
v2	.aif-bin	aifbin_v2.py	AI Formatted - Binary	Binary (MessagePack)

AIMF - AI Memory Format (v1)

Simple, human-readable JSON. Uses .aimf extension. Great for learning and debugging.

Usage

AIMF Commands (aifbin_v1.py)

Windows:

python aifbin_v1.py migrate sample.md      # Convert to AIMF (JSON)
python aifbin_v1.py info sample.aimf       # View file info
python aifbin_v1.py chunks sample.aimf     # List chunks
python aifbin_v1.py extract sample.aimf    # Extract original content

Linux / macOS / WSL:

python3 aifbin_v1.py migrate sample.md      # Convert to AIMF (JSON)
python3 aifbin_v1.py info sample.aimf       # View file info
python3 aifbin_v1.py chunks sample.aimf     # List chunks
python3 aifbin_v1.py extract sample.aimf    # Extract original content

AIF-BIN Commands (aifbin_v2.py)

Windows:

python aifbin_v2.py migrate sample.md              # Convert to AIF-BIN (binary)
python aifbin_v2.py info sample.aif-bin            # View file info

Linux / macOS / WSL:

python3 aifbin_v2.py migrate sample.md              # Convert to AIF-BIN (binary)
python3 aifbin_v2.py info sample.aif-bin            # View file info
python3 aifbin_v2.py chunks sample.aif-bin          # List chunks
python3 aifbin_v2.py extract sample.aif-bin         # Extract original content
python3 aifbin_v2.py upgrade sample.aimf            # Upgrade v1 to v2

Troubleshooting

error: externally-managed-environment (Debian/Ubuntu/WSL)

This error occurs when pip tries to install packages system-wide in environments where Python packages are managed by the OS.

Solution 1: Use the --break-system-packages flag:

pip3 install -r requirements.txt --break-system-packages

Solution 2 (Recommended): Use a Python virtual environment:

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python3 aifbin_v2.py --help
# Deactivate when done:
deactivate

python3 not found on Windows

On Windows, use python instead of python3:

python aifbin_v1.py --help

Migrating from AIMF to AIF-BIN

Why Migrate?

• 50% smaller files — Binary format is more compact
• Faster parsing — Fixed-offset headers enable direct seeks
• Checksums — CRC64 verification for data integrity
• Embeddings — AIF-BIN supports vector embeddings for semantic search
• Typed chunks — TEXT, TABLE, IMAGE, AUDIO, VIDEO, CODE

How to Migrate

Option 1: Using the CLI (Recommended)

# Windows
python aifbin_v2.py upgrade sample.aimf -o sample.aif-bin

# Linux / macOS / WSL
python3 aifbin_v2.py upgrade sample.aimf -o sample.aif-bin

Option 2: Programmatically

from aifbin_v2 import migrate_from_v1

migrate_from_v1('sample.aimf', 'sample.aif-bin')

See examples/migrate_v1_to_v2.py for a complete migration script.

Lite vs Pro

AIF-BIN Lite (this repo) handles the format — converting your documents into portable, structured files.

AIF-BIN Pro adds the intelligence — AI-powered semantic search that lets you query your documents by meaning, not just keywords.

Why This Architecture?

• Your data stays portable. Lite files work anywhere, with or without Pro.
• No vendor lock-in. The format spec is open (MIT). Build your own tools if you want.
• Pay for intelligence, not storage. Lite is free forever. Pro adds the AI layer.

Ready to Upgrade?

AIF-BIN Pro includes:

• Semantic search — Find by meaning, not keywords
• Batch processing — Convert entire directories
• Watch mode — Auto-sync on file changes
• Web Inspector — Visual file analyzer
• 5 embedding models — OpenAI, Cohere, local options
