- **Reuse your voice and briefs (Content writer):** Keep brand guidelines, tone notes, and past outlines on hand and inject them so every drafting session sounds consistent.
- **Build a searchable research log (Researcher):** Let the extension archive your literature questions and answers, then recall them when writing up findings.
- **Keep AI memory off the cloud (Privacy-conscious power user):** Maintain a personal memory bank locally instead of enabling vendor-side memory features you don't fully control.
