Alex vs. Tenzo

Tenzo is an AI recruiter that screens over voice and video, with behavioral integrity signals, an identity check, SOC 2 Type II and full calendar coordination. Alex runs the whole process: interviews over video, phone and WhatsApp, an integrity threshold you set per role, write-back to 100+ ATS platforms, and automatic scheduling. Tenzo fits a voice-and-video funnel on a mainstream ATS. Here's the side-by-side.

What each tool actually is

Tenzo is an AI recruiter. It runs screening conversations itself over voice and video, scores it, applies behavioral integrity signals plus an identity check, coordinates interview times against calendars, and integrates with 57+ ATS platforms.

Alex is an AI recruiter with a wider surface. Interviews run over video, phone and WhatsApp, with SMS carrying invitations, reminders and scheduling. Alex verifies candidate integrity and identity, coordinates scheduling against live calendars with time-zone detection and blackout windows, and syncs results into 100+ ATS platforms.

Where Tenzo fits

Voice and video quality. Both modalities are well built — and both assume bandwidth and a quiet twenty minutes, which is not the frontline funnel.

If voice-and-video screening on an ATS inside Tenzo's 57 is your only constraint, Tenzo will do the job.

Where Alex pulls ahead

Reach beyond voice and video

Tenzo interviews over voice and video. For a salaried candidate with bandwidth and a quiet twenty minutes, that's enough. It is not most of a volume funnel.

Alex adds WhatsApp, which is a different axis of reach rather than one more feature. WhatsApp does calls and messages, it's already installed, and it runs on wifi instead of billable minutes. For candidates across the globe, it simply is the phone. SMS then carries the orchestration around the interview — invite, reminder, reschedule — which is where volume funnels leak before a conversation ever happens.

Integrity signals with your thresholds on them

Alex scores video, audio and transcript for external assistance, AI-generated answers, multiple speakers, eye and head movement and voice-changing tools, against a threshold you set anywhere from 0 to 100 per role. Interviews that cross it are flagged for human review, with the reasons broken out by analysis type in the candidate report. Fraud verification scores identity separately as Low, Medium or High — disposable email domains, VOIP numbers, VPN use, CNAM mismatches, résumé-to-profile inconsistencies — and an optional document-and-selfie ID check switches on per job.

What to test in a pilot

Run both tools against the same requisition and measure:

• Completion rate on your hardest-to-reach role, not your easiest
• Days from application to a scored, reviewable interview
• Share of interviews flagged for integrity review, and the false-positive rate once your team reads them
• Whether scores and transcripts write back to your ATS without a manual export

The verdict

Choose Tenzo if voice-and-video screening covers your candidates and your ATS is on their list. Choose Alex if you're reaching frontline or international candidates who need WhatsApp, or if you want integrity thresholds you set per role and results landing across 100+ ATS platforms.

See Alex on your own roles

The fastest way to settle this is to watch Alex run a requisition you're actually struggling to fill. In 30 minutes we'll screen for that role, show you the integrity signals on a live interview with your threshold set, and connect Alex to your ATS so you can see results land where your team already works.
