Key takeaways
- Best breadth of any single assistant subscription.
- Analysis over uploaded files is the standout feature.
- Citations and very long documents remain weak spots.
- Enterprise controls are the most mature in the category.
What it does better than anything else
Uploading a messy spreadsheet and getting a cleaned analysis with charts in one turn is still the clearest productivity win in the category. The Python sandbox turns vague questions into reproducible work.
Custom GPTs make institutional knowledge reusable: one well-built internal GPT saves more time than a dozen personal prompt files.
Where it falls short
Citations remain the weakest area. For anything published externally, a dedicated answer engine is a safer first pass.
Very long documents degrade before the stated limit, and rate limits on the strongest models still interrupt deep work sessions.
Verdict
If your organisation buys one AI subscription, this is still the one. Budget for a second specialist tool once a specific bottleneck — research, long documents or repo-scale coding — becomes measurable.

Frequently asked questions
Is Plus worth $20?
For anyone using it more than twice a week, yes — the frontier model and file analysis alone justify it.
