Your journal entries, cryptographically verified, encrypted, and permanently preserved. Because your life story should belong to you — forever.
The Problem
Planes have flight recorders. Cars have dash cams. Companies have audit logs. But the most complex system on Earth — a human life — has no verifiable, tamper-proof record.
You forget 70% of new information within 24 hours. Your most important decisions fade into fragments.
Your life is stored across dozens of apps and platforms — none of which you truly own or control.
AI can generate fake photos, voices, text, and video. Proving what's real gets harder every day.
Quick Start
Install the SDK, create a vault, write a memory. It's hashed, encrypted, signed, and optionally anchored — all in one call.
from diaryvault_memory import MemoryVault # Initialize your vault vault = MemoryVault(encryption_key="your-secret-key") # Create an immutable memory memory = vault.create( content="Today I decided to quit my job and start a company. " "I've never been more terrified or more alive.", tags=["career", "milestone"] ) # ✓ SHA-256 hashed # ✓ AES-256 encrypted # ✓ Timestamped & signed print(memory.hash) # a7f3b2c1d4e5... print(memory.verified) # True # Anchor to permanent storage vault.anchor(memory, backend="arweave")
Architecture
Every memory flows through capture, synthesis, verification, and permanence — each layer adding a guarantee that your record is real, private, and enduring.
Manual entries, AI agents, API integrations, photo and voice capture. Everything starts here.
AI narrative generation, pattern detection, emotional analysis. Raw data becomes meaningful story.
SHA-256 hashing, AES-256-GCM encryption, HMAC signing, Merkle trees. Every byte is provable.
Local encrypted storage, Arweave, Ethereum L2, IPFS. Choose your level of forever.
Features
Encryption
AES-256-GCM encryption happens on your device. Your key never leaves. Not even we can read your memories.
Verification
Every entry is SHA-256 hashed, timestamped, and signed. Prove exactly when you wrote what you wrote.
Permanence
Optionally anchor hashes to Arweave, Ethereum L2, or IPFS. Tamper-proof permanence, no tokens required.
AI Agents
Pluggable agents that autonomously capture, synthesize, and enrich your daily memories. Bring your own LLM.
Open Format
Documented, open memory format. Your data is never locked in. Export everything, anytime, forever.
Legacy
Designate trusted parties who inherit access to your vault after a configurable period of inactivity.
Use Cases
Open Core
The Memory Layer SDK is MIT-licensed. Build on it, fork it, self-host it. DiaryVault is the beautiful app built on top.
