Record a memo about what needs doing and upload it through the built-in n8n form. Google Gemini transcribes the audio directly - no separate speech service needed - and a Basic LLM Chain with Gemini turns the rambling transcript into a clean task list, pulling out each task with an owner, a due date (resolving relative dates like \"Friday\"), and a priority. The summary and tasks are emailed to you, and each task is split into its own row in Google Sheets so it drops straight into your tracker. Unreadable recordings trigger a helpful email instead of failing silently.\n\n### Setup\n1. Connect Google Gemini (PaLM) API, Google Sheets and Gmail.\n2. Point the Save Tasks node at your spreadsheet (tab: Tasks).\n3. Open the form on your phone and record a memo.\n\n### Customization tips\nPush tasks to Notion, Todoist or Trello instead of Sheets."
