Memory Logger

Memory Logger solves a friction problem: during a trip, you never take the time to write. The journal stays empty. Memories fade. Memory Logger reduces friction to zero — a voice or text message is all it takes, the rest is automatic.

How it works

You send a message to a Telegram bot — voice, photo, or text — from anywhere. The n8n workflow takes over:

1. Transcription — Voice messages go through OpenAI Whisper
2. Structuring — GPT-4o identifies the location, date, people mentioned, emotions
3. Writing — GPT-4o generates a first-person narrative with highlights from the moment
4. Archiving — Everything is pushed to Notion: journal entry, locations database, trip summary

By the end of your stay, you have a complete journal without having written a single line yourself.

Architecture

Telegram Bot — Single entry point

• Accepts text, audio, and photos
• No commands to learn — send as if you were texting a friend

n8n — Central orchestrator

• Workflow triggered on every Telegram message
• Branches by message type (voice/text/photo)
• Sequential calls to Whisper then GPT-4o
• Writes to Notion via API

Notion — Memory database

• One page per trip (created automatically)
• One entry per message with date, location, structured text
• Auto-generated trip summary at the end of the stay

Why n8n and not custom code?

n8n lets you modify the workflow visually without touching code. Adding a new source (WhatsApp, email), switching the GPT model, adjusting the prompt — all done in minutes. For a personal tool that evolves, this is a pragmatic decision.
