EchoLantern: A Private Little Archive for Memories

Description and use

EchoLantern lets users create memory keepsakes locally with Gemma 3 1B, storing data in browser storage and keeping privacy intact.

Problem

Users want AI‑assisted memory writing without sending personal notes to a hosted service.

Outcome

EchoLantern enables private, AI‑assisted memory creation without external data transmission, while keeping the original note visible and allowing user edits.

Workflow

• 1. Open EchoLantern locally via Node server.
• 2. Enter rough notes and optional photo.
• 3. Click generate to invoke Ollama with Gemma 3 1B and a JSON schema.
• 4. Review the draft keepsake, edit if needed.
• 5. Save to local archive in browser storage.
• 6. Export archive as Markdown or JSON if desired.

Evidence

EchoLantern is a local‑first keepsake maker for everyday memories, people, places, pets, family stories, and meaningful objects or traditions.

Source

When run locally, the server uses Gemma 3 1B with an explicit JSON schema to return a consistent keepsake structure.
