Editor-selected existing cases and prompts, separate from AI news. Selection dates use Hong Kong time.
Five existing cases: reports, decks, photo expansion, brand context and surveys. Canva AI decks: limited free quota; availability varies by account, region and language. Photoshop web: desktop browser and plan/trial; credits depend on plan/model. ChatGPT and Gemini Notebook web list Taiwan, not HK/Macau. Plan limits and mobile features vary. Untested; check outputs and upload rights.
Add documents on one topic to NotebookLM, name the points to compare, and request a source-linked comparison to check against the originals.
Prompt
Using only the selected sources, compare their statements about [topic/question] across [comparison dimensions]. Group findings into agreement, disagreement and insufficient information, with source citations for each point. Do not treat silence as disagreement. Distinguish explicit statements from your synthesis, then suggest questions for further research.
Evidence limits and cautions
- Sources may be outdated or biased. A citation does not guarantee accuracy.
- Some Google help pages now use the name Gemini Notebook.

Upload a de-identified survey spreadsheet and ask ChatGPT to inspect columns, group comments and count replies, retaining row references for checks.
Prompt
First inspect this de-identified survey for columns, missing values and possible duplicate responses. Explain how you identify duplicates; do not delete them without confirmation. Derive themes from the responses without forcing a fixed number. Give response counts, traceable anonymous row references and faithful summaries for each theme. Allow multiple themes per response; state the total valid response count and counting method. Include rare but important comments.
Evidence limits and cautions
- Small or self-selected samples may not represent all customers.
- Do not infer sensitive traits or invent missing responses.
