I gave Codex a login to my SaaS. Astra turned that into a 4-minute product demo with a voiceover. I recorded exactly 0 seconds of it. Holy shit. I used to record demos in Screen Studio, and I could never get a take I was happy with. Too fast. Too slow. Some tiny mistake halfway through that made me wonder if I really wanted potential customers seeing it. So I'd do the whole thing again. This time, I gave Codex, running Astra, an account for BillionVerify, the email verification product I'm building. It logged in and actually used the app. Opened the dashboard. Verified an email. Ran a bulk check. Uploaded a file. Checked the results. Recorded the walkthrough. Then I gave it an ElevenLabs API key. It made the voiceover, synced the subtitles, and put everything together in Remotion with animations and transitions. The video below is what came out of that. And the best part: if the recording sucks, I can just ask Astra to try again. It can do another take. And another. I don't have to sit there repeating the same clicks, trying to get the timing right. I watch the result, give feedback, and let it handle the next pass. Astra in Codex is fucking wild. Can you spot anything the AI got wrong? Watch it, then mess around with billionverify.com/ and tell me what Astra got wrong. Tell me if the AI actually got it right.
