| Compare | Perplexity | Exa |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Developers adding cited, real-time web answers | AI agent developers needing live web data |
| Who it's not for | High-volume chatbots . per-query pricing piles up fast | Non-technical teams . raw API, no UI |
| Privacy | No public API vulnerabilities found; the Comet browser/agent had multiple disclosed prompt-injection and hijack flaws in 2025-2026.10 | SOC 2 Type II certified with a public vulnerability disclosure policy; no public vulnerabilities found in the sources reviewed.15 |
| Support quality | Trustpilot reviewers report 'very poor customer service' | No support evidence in sources |
| Public sentiment | Users love the fast, cited research but increasingly complain about shrinking value, rising per-query costs, and poor support.⁷ | Reddit developers praise its fast, agent-focused search and G2 shows 4.8/5, but independent review volume is tiny and cost versus rivals is a recurring question. |
| Biggest gotcha | Support quality: Trustpilot reviewers describe very poor customer service when issues arise.⁶ | Pricing has changed since launch; confirm current rates before budgeting |
