Strengths

- Productivity multipliers: Instant summaries (articles/videos/PDFs), writing aids (paraphrasing/emails/social posts), and artifacts (code/diagrams)
Limitations
- Hidden credit limits on "unlimited" plans: Free tier has daily caps; paid "unlimited" enforces a $100/month equivalent spend limit on API calls, potentially throttling heavy users
