v1 · indie AI builder build
Your AI broke for 3 personas last night. You'd want to know before your customers do.
PersonaLab synthesizes personas from your own support transcripts and runs them through your AI every night. We send a Telegram alert only when something that used to work, 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 ship a prompt change Friday and discover it broke checkout-Q&A on Tuesday — from an angry customer, not from a test.
- Pain · 02
Manual 'chat with it for 10 minutes' testing misses everything weird real users actually try.
- Pain · 03
You don't have a QA team, you're not going to hire one, and you don't have time to babysit your bot.
Pricing
$29/month per AI endpoint monitored.
A 6 AM Telegram ping when your AI broke overnight — and silence when it didn't. Every silent regression is one angry-customer Slack ping away. Stop the surprise — your first audit is free.
Every persona uses verbatim utterances pulled from YOUR own customer data. No fabricated test cases. We verify post-hoc.
