CareerWhat people rehearse

Salary review on Friday

“Salary review with my manager Linda. She tends to deflect. I want £8k more.”

How it works

Three steps. Sixty seconds to your first session.

01

Describe the scene.

One sentence. Who you're talking to, what you want, what you're afraid of. The AI builds a partner with tactics, personality, and a voice.

02

Press start.

A voice picks up. You talk. They talk back. Press and hold to speak, release to let them respond. As real as rehearsing with a human.

03

Get the debrief.

Five scores, three lines you could have used, one specific thing to try next time. Run it again until you're ready.

Pricing

Questions

Asked, answered.

Is the AI any good at this?+

It's not magic, and it won't replace a human coach or therapist. But it's a calm, patient partner who'll run the same hard conversation with you ten times in a row without judging — and the debrief catches things you'll miss on your own. It's better than rehearsing in front of a mirror.

What does my audio get used for?+

Your audio stays in your account. We don't train models on it, share it with other users, or sell it. How long your session history is kept depends on your plan — 7 days on Free, 30 days on Pro, forever on Elite — and you can delete any session yourself at any time.

Can I rehearse something heavy — grief, an apology, an end-of-life talk?+

Yes, carefully. Sensitive scenarios show a warning and a link to real support (Samaritans, 988, befrienders.org). The Gentle difficulty makes the partner softer. You can also block whole categories in Settings if you'd rather not be suggested them.

What languages does Razen support?+

Razen runs in English today, with more languages on the roadmap.

What if I cancel?+

Cancel any time in Settings → Billing. You keep access until the end of the period you've paid for. Your data stays unless you delete it. Delete your account in Settings → Danger and we wipe everything within 30 days from backups.
