## What is Sown Echoes?

Sown Echoes lets you actively capture your thoughts, values, and life experiences as structured data — creating a digital legacy that trains future AI models to think like you.

YOUR ECHOES LIVE FOREVER
Every thought you record, every value you express, every story you tell becomes part of a living digital legacy. Your unique perspective contributes to the collective wisdom of humanity through open AI training data.

KEY FEATURES

• Cryptographic Identity — BIP-39 mnemonic phrase creates your unique Meme ID. No accounts, no passwords, no servers.

• Voice & Text Recording — Capture ideas through typing or voice with on-device Whisper transcription. Your words, your way.

• Guided Questionnaires — Structured prompts across Life Narrative, Values, Beliefs, Relationships, Experiences, Aspirations, Emotional Maps, and Knowledge categories.

• Echo Shadow (AI Mirror) — Word clouds, values radar charts, and AI-generated persona summaries reveal patterns in your thinking.

• Echo Chat (Digital Twin) — Chat with an AI version of yourself, powered by on-device RAG and your own entries.

• Dual-Track Sharing — Keep entries private in your vault, or contribute them openly under CC-BY-SA 4.0 to the Human Wisdom Library on Hugging Face.

• Full Preview Before Publishing — Review all PII-stripped content before public contribution. You have the final say on what gets published.

• iCloud Backup — Encrypted backup to your private iCloud account. Your data stays yours.

PRIVACY BY DESIGN
All AI processing runs entirely on your device. No user data is collected. No internet required for core features. Personal information is automatically stripped before any public contribution.

OPEN CONTRIBUTION
Choose to inscribe your wisdom into the Human Wisdom Library — an open dataset on Hugging Face for training AI models. Your thoughts become the foundation for more human-like AI, carrying your values forward through generations of technology.

Built with love for humanity's digital future.
