Project Overview I would like to build a workflow that lets me select English words or sentences from a PDF (or manually input text), send them to the OpenAI API for linguistic analysis, parse the resulting JSON, and automatically register the data into a Notion database. The workflow must run inside the iPad/iOS Shortcuts app and support both PDF selection and manual input. Required Workflows 1. Shortcut A — From PDF sharing (Main flow) User selects text in a PDF viewer (Notion PDF, GoodNotes, Apple Books, PDF Expert, etc.) Launches the shortcut from the Share Sheet Shortcut sends text to OpenAI API Receives structured JSON Parses JSON safely Sends processed data to Notion DB Creates a new row 2. Shortcut B — Manual Input Prompts user to input a word or sentence manually Reuses the same processing logic as Shortcut A 3. Shortcut C — Core Processor (Subroutine) Handles: OpenAI API request JSON parsing CEFR classification Sentence splitting Duplicate checking Notion database registration Reused by the other two shortcuts Functional Requirements ① CEFR Difficulty Level Classification Determine CEFR level (A1–C2) for the word or phrase. Save the CEFR value into a Notion Select field. CEFR options must be fixed: A1 / A2 / B1 / B2 / C1 / C2 ② Multi-Sentence Handling If the selected text contains multiple sentences: Normalize and clean the text Split safely into individual sentences Ensure example generation and analysis run correctly per sentence Final JSON should remain stable and parse-safe ③ Duplicate Record Check Before creating a new Notion row: Search the database for the same Word value If found → Display “This word already exists. Do you want to add it anyway?” User chooses Register or Cancel ④ JSON Output Requirements The OpenAI API must return JSON only, no extra text. Required JSON keys: { "word": "", "meaning_ja": "", "pronunciation": "", "example_en": "", "example_ja": "", "part_of_speech": "", "cefr": "" } ⑤ Notion Database Mapping The Notion database contains these properties (in this order): Word — Title Meaning — Rich text Pronunciation — Rich text Example (EN) — Rich text Example (JP) — Rich text Part of speech — Select CEFR — Select Important: In the future, I may add or rearrange Notion properties. The shortcuts must continue working even if property order changes (property names will remain the same). Technical Requirements OpenAI API Endpoint: POST https://api.openai.com/v1/chat/completions Model: gpt-4.1-mini (or recommended) Strict JSON output enforcement Notion API Endpoint: POST https://api.notion.com/v1/pages Version: 2022-06-28 or latest stable Must support property mapping and stable error handling Deliverables Shortcut A: “Add from PDF to Notion” Shortcut B: “Add Word to Notion (Manual Input)” Shortcut C: “Core Vocabulary Processor” Short demo video (screen recording) Brief usage manual (1–2 pages): How to use the shortcuts How to replace API keys How to adjust Notion DB settings
