Generate LinkedIn & Twitter Posts from Telegram Voice Replies with GPT-5

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 this 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.
