User Research Without the Support Nightmare
Or the missing panel
Lookback has a 2.1/5 support rating and no built-in participant panel — you recruit yourself. TestSynthia replaces both problems: 1M+ stateful AI personas, instant results, and no support dependency. $2.99 to start.

The Comparison
Broken support + no panel vs. instant simulation.
TestSynthiaThe Pain
Lookback's gaps are expensive.
The Support Abyss
Lookback's 2.1/5 support rating isn't a fluke. Users report ignored tickets, unresolved bugs, and platform downtime with no communication. When research is time-sensitive, broken support is a dealbreaker.
The Missing Panel
Lookback provides interview tools but no participants. You pay for the platform AND recruit yourself. That's two problems when you thought you were buying one solution.
The Technical Debt
Users report frequent connectivity issues, recording failures, and sync problems. When a moderated session fails, you lose the participant, the time slot, and the insight. Triple loss.
When to Choose
Which Platform Actually Works?
Use Both If...
Use TestSynthia for rapid validation and concept testing. Use Lookback for live moderated sessions with your own recruited users — if the platform is working that day.
Choose Lookback If...
You have your own participant pool and need moderated video interview tools. You're willing to tolerate support issues for specific feature sets.
Choose TestSynthia If...
You need reliable, instant research without recruitment headaches or support dependency. You want results, not troubleshooting.
