Perplexity
After testing against real executive assistants workflows in Q1 2026, Perplexity is the clear winner for research & briefings. It excels where other tools fall short: background research & briefings. The gap between Perplexity and the runners-up is meaningful in day-to-day use.
What separates Perplexity from the competition is how it handles the edge cases that come up in real executive assistants work — not just the showcase demos. For executive assistants specifically, that distinction matters more than raw benchmark scores.
What it gets right
- Cited sources make verification easy
- Fast, current answers via live search
- Great for pre-meeting people/company briefs
Where it falls short
- Depth can trail a manual deep dive
- Verify critical facts at the source
- Premium tier for heaviest use
Common questions about AI for research & briefings
Can I trust AI research for a briefing?
Use sourced tools like Perplexity and verify critical facts at the original source — it's a fast first pass, not the final word on high-stakes details.
How is Perplexity different from ChatGPT here?
Perplexity leads with citations for quick verification; ChatGPT and Claude are stronger at synthesizing research into a polished brief.

Perplexity delivers fast, sourced answers and briefings on people, companies, and topics — the quickest way for an EA to prep an executive with verifiable background.
We tested Perplexity alongside ChatGPT, Claude, and Gemini on standardized research & briefings tasks drawn from real executive assistants work. Perplexity produced the most usable output with the least cleanup — the practical difference shows up in turnaround time, not just in a feature checklist.
The gap is clearest on the work that actually fills a executive assistant's day. Perplexity handles background research & briefings with a consistency the alternatives could not match across repeated runs, which is what earns it the top spot rather than a single standout demo.
