画像を自動のにOCR → AI要約 → GoogleテーブルとGmailでの通知

中級

これはDocument Extraction, AI Summarization分野の自動化ワークフローで、15個のノードを含みます。主にCode, Gmail, GoogleDrive, HttpRequest, GoogleSheetsなどのノードを使用。 Google Driveの画像からOCR.spaceを使ってテキストを抽出し、OpenRouter AIで要約をテーブルとGmail通知へ

前提条件
  • Googleアカウント + Gmail API認証情報
  • Google Drive API認証情報
  • ターゲットAPIの認証情報が必要な場合あり
  • Google Sheets API認証情報
