Should I Buy It?
Idea Logger is the first link in my productivity system. When an idea arrives — in the street, in the shower, in a meeting — you have a few seconds before you lose it. Sending it to a Telegram bot takes 3 seconds. Opening an app, finding the right folder, categorizing it: 2 minutes. Idea Logger eliminates that delta.
How it works
You send a message to the bot — voice, text, or both. The n8n workflow takes over:
- Transcription — Voice notes go through OpenAI Whisper
- Enrichment — GPT-4o categorizes the idea (project, concept, task, question), extracts keywords, evaluates urgency
- Archiving — The idea lands in Notion with all its metadata: category, tags, date, source, estimated ICE score
The next morning, you have an inbox of structured ideas in Notion — ready to be sorted.
Architecture
Telegram Bot — Instant capture
- Zero friction: same interface as WhatsApp, no additional app
- Accepts voice notes (up to 5 minutes), text, and combined notes
n8n — Orchestration
- Telegram webhook triggered on every message
- Branches by type (voice → Whisper first, then GPT; text → GPT directly)
- Structured GPT prompt to extract: title, summary, category, tags, effort estimate
Notion — Ideas database
- “Inbox” view: all unsorted ideas
- “By project” view: ideas grouped by theme
- Fields: title, summary, category, tags, date, estimated effort, status (new/in-progress/archived)
Connection with the rest of the ecosystem
Idea Logger feeds directly into Todo Manager: ideas marked as “task” in Notion are picked up by the Todo Manager workflow and transformed into actionable tasks with priority and estimated duration.
