PracticeDifficultTalkswith AI
Assertr is a mobile app that lets you rehearse tough workplace conversations through real-time voice AI. Practice salary negotiations, giving feedback, and handling conflicts with AI opponents that adapt to your every word.

Difficult conversations shouldn't be improvised
Most people walk into salary negotiations, feedback sessions, and conflict discussions completely unprepared. The result: lost money, damaged relationships, and missed opportunities.
Assertr gives you a safe, private space to practice before the real thing. No judgment, no consequences — just a voice AI opponent that adapts to your arguments and pushes back like a real person would.

Real results from real conversations
People who practiced first performed better when it counted.
“Had a tough performance review coming up. Ran through it twice the night before. The AI played my direct report way more defensively than I expected - made me rethink my whole approach.”
David T.
Engineering Manager
“Honestly skeptical at first - talking to an AI felt weird. But after a few rounds of interview practice, I started catching my own weak answers. Got an offer at my second attempt, not my first.”
Rachel S.
Career Changer
“I prep before important client calls now. It won't replace real experience, but hearing objections before the actual meeting helps me stay calm. Closed two deals I was nervous about.”
Mike P.
Account Executive
“Needed to push back on a deadline my PM set. I tend to just agree and then burn out. Practiced saying no three different ways - ended up negotiating a realistic timeline without any drama.”
Lena K.
Senior Developer
“Used it to rehearse my pitch before a demo day. The feedback on my pacing was spot on - I was rushing through the problem slide. Still nervous on stage, but way more prepared.”
Chris J.
Startup Founder
“A client kept scope-creeping and I didn't know how to bring it up without losing them. Assertr helped me find wording that was direct but not aggressive. The conversation went better than I hoped.”
