About This Workflow
Staying consistent with personal brand content is hard when you're running everything yourself. You know what you want to say — but turning raw thoughts into polished posts takes hours.
This workflow handles the writing. Every day at 4 PM it sends you a question via Telegram based on your topic list. Answer by voice or text. GPT-5 converts your raw answer into two drafts — a short punchy post and a longer detailed one — both saved to Google Sheets with status "Review." Your only job: add your personal touch and publish.
What it does: Daily at 4 PM the workflow picks 4 random topics from your list, generates one question per topic using GPT-5, and delivers them one-by-one to your Telegram. You reply by voice note or text. Voice replies are transcribed via OpenAI Whisper. GPT-5 then writes a short post (1–5 sentences) and a long post (6–10 lines) from your answer. A one-time voice interview builds your profile — who you are, your audience, your topics — stored in Google Sheets to power all future prompts. Marking any post "Regenerate" triggers an automatic rewrite.
Who is it for: Solopreneurs and creators who want to publish consistently on LinkedIn or Twitter without spending hours writing.
APIs used: Telegram Bot API for question delivery and reply capture, OpenAI Whisper for voice transcription, OpenAI GPT-5 + GPT-5 mini for questions, posts, and context processing, and Google Sheets API for profile storage and review queue.
Estimated cost per run: Whisper ~$0.006/min of audio - GPT-5 token costs vary - check OpenAI pricing.

Questions
Everything you need to know before getting started.
Both work. If you reply to the Telegram question with a voice note, it gets automatically transcribed by OpenAI Whisper. If you prefer typing, just send a text reply instead. The workflow handles either format and passes your answer to GPT-5 for post generation.
Your topic list is stored in a Google Sheet that you control. During the one-time setup interview, you tell the workflow who you are, what you write about, and who your audience is. GPT-5 uses this profile to generate relevant, tailored questions daily from whichever four topics it randomly picks from your list.
No, posts are never published automatically. The short and long post drafts are saved to your Google Sheet with status "Review". You read them, add your personal touch, and publish manually. This keeps you in control of what goes out under your name.
Yes. The workflow uses OpenAI nodes which you can swap for any LLM supported by n8n — such as Anthropic Claude or Google Gemini. You would update the node type and model ID in each AI step. GPT-5 mini is already used for the cheaper context-processing steps to keep costs low.
Nothing breaks. The workflow simply waits for your reply via the Telegram trigger node. If you don't respond, no post is generated for that day. The next day's schedule trigger fires as normal. There's no backlog or catch-up — each day is independent.
