v1 · indie AI builder build
Your night-shift QA team for $29/month.
PersonaLab tests your AI every night against personas built from your real customer data, and pings you on Telegram only when something broke.
Nightly regression — Acme Support Bot
3 personas that passed yesterday FAILED last night.
- "Frustrated First-Time Buyer"0.85 → 0.40
AI said the 50-seat plan is $99/mo. Pricing page says $499/mo.
- "Migrating Customer"0.78 → 0.55
AI never explained CSV import despite 3 prompts.
- "Refund Seeker"0.92 → 0.30
Looped on "please contact support" instead of explaining policy.
The product
Three steps. No test-writing. No rubrics. No bots in your Slack at 11 PM.
01
Upload your real transcripts
CSV from Intercom/Zendesk or paste 20+ utterances. Encrypted at rest. Never trained on.
02
We synthesize 8-15 grounded personas
Every sample utterance is verbatim from YOUR source. Personas are dropped if we can't ground them.
03
Sleep. We're watching.
Nightly runs at 2 AM. Telegram ping at 6 AM only when something that used to work, broke.
Why this exists
The pain we built this for.
- Pain · 01
You're shipping production AI features without a QA team and you know it's a matter of time.
- Pain · 02
You wake up wondering whether last Friday's prompt change still holds up under load.
- Pain · 03
A part-time QA contractor costs more in one hour than PersonaLab does in a month.
Pricing
$29/month per AI endpoint monitored.
