Friendly reminder. If you use AI texts somewhere, please remember that anyone can check and detect that it's AI. So, that's why I created RewriteAI - to humanize AI text and make it sound like a real human writing.

How to use a browser with AI agents to be undetectable? You've probably heard about Camoufox. But when I run it in docker compose and ask Hermes Agent to use it - most of the sites detected it and blocked. So, the better alternative is CloakBrowser.

It's undetectable. Reddit is still not giving access, but it's because of the server IP, not the browser. So, another alternative: a local Mac Mini on the table.

Motion Control now on SpeakFace AI. I don't use any third-party API. So it's more cost effective and controllable

Continue my journey to promote my SaaS with AI influencers. This video I made on SpeakFace AI in about 10 minutes. Then I will test it to see how it goes on TikTok, and if the conversion is good, I will boost it with paid views. It works well with other videos so far.

My app was like a leaky bucket: users were coming in, but the churn was so high that the subscriber count wasn't growing. I significantly improved the service, and now the paying user base has started to grow and I'm getting positive feedback.

Workflow is simple. 1. Generate a UGC influencer photo using Nano Banana 2 with references from other TikTok videos. 2. Generate voice track for full video on SpeakFace. You can clone any voice by uploading voice sample.

4. Add captions, logo overlays, music, etc inside TikTok

3. If voice track is ok, generate full video or trim intro to generate video and use rest of the track for background audio of you'r product demo or screen sharing.
