Show HN: X11.social – Call, talk, publish: voice-first AI for X with live demo

I built a tool to turn your ideas into X posts directly by taking a phone call to a conversational AI.

x11.social started voice-first. Now, it features an AI chat interface as well with smart UI elements like "give me 10 tweet options" that offer clickable CTA options.

This isn't a complete shift. It's the voice core, enhanced with chat for a smoother workflow and easier content creation.

Call a number or use your browser mic for voice dumps. It's hands-free, perfect for walking, driving, or just thinking out loud. With UI chat, you can craft deeper thoughts or continue from the voice convo where you left off.

This is my first SaaS after years in dev. Building the AI and editor is the fun part. Distribution? That's the real challenge.

Tested some ads, but data showed the funnel was broken. First fix: added free demo button on the landing page that lets users try browser voice to a demo account in real-time. No signup needed. Registered users unlock real calls.

I'm building in public, including video logs. A year ago? Never thought I'd do that. I'm open to ideas.

For your target audience it might not matter, but for the hn crowd this is potentially a very confusing naming collision. Especially since the X logo already looks so much like the X11 Window System logo.

Fair. X11 is ElevenLabs-inspired voice tech, X for the platform + 11 for AI voice.

I kept the name for the call-to-tweet vision. Thoughts on the demo?
