From the desk at X11
Notes on building X11, writing for X, and learning when to leave a draft alone.
Building X11
The last post on this blog was in August 2025. If you checked in after that and thought X11 had gone into shadow mode, fair enough. A silent blog is a poor way to show that something is alive.

I rarely get an idea in the shape of a finished post. It arrives while I’m doing something else, usually as a half-sentence that makes sense to me and nobody...

A lot of tools treat X as a place to broadcast. I fall into that habit too: write the post, check the numbers, repeat. Meanwhile a good reply from someone...
How it works
The most useful post idea often isn’t in a trending feed. It is in a note you wrote after a customer call, a voice memo on the way home, or...
Engineering
Our voice AI extension lets you call your assistant and create content by speaking—just like a phone call. But Twitter's CSS destroyed the voice widget, YouTube broke our console, and...
Building in Public
We submitted the Chrome extension for review, made mobile 5x faster, and the context-aware demo keeps converting. Here's what changed and why it matters.
Building in Public
I've shipped, tweaked, and rebuilt my product in public for almost 2 months. It's not always pretty, but the progress stacks up. Here's what consistency actually looks like.
Features
Chrome extension that captures page context for your AI assistant. Voice and chat interfaces share context - the AI knows what you're reading across all input methods.
Features
ChatGPT gives you text. We give you buttons that publish. Context-aware actions that appear exactly when you need them.
Technical
ElevenLabs Conversational AI costs $0.10/minute. But even that adds up. Here's why custom infrastructure makes sense at scale.
Features
Added a cursor-style chat that brews content by calling tools. Built in just 2 days.
Features
Other tools need perfect inputs. We accept chaos. Voice rambles, random links, screenshots, brain dumps - drop it all in. Perfect posts come out.
Events
Went to the Cursor AI meetup in Tallinn. Demoed X11.Social and talked about voice tech. The story of how a hackathon voice bot became a social media tool.
Product Update
I shipped Creator Chat in 2 days. It's like having ChatGPT's brain specifically for X. Drop thoughts via voice/text/links/images. Get polished threads. No prompts needed.
Product Strategy
I added a demo button on the front page. No signup. No phone number. Just instant access.
Features
What if your AI assistant called you every morning? Our social media post scheduler with conversational AI lets you speak to tweet on autopilot. Call to tweet technology that actually...
Startup Journey
Shipped in two weeks, iterated daily, ran ads. Numbers: 7 registrations, 0 payments, burned $750. Here's what I learned about building in public.
Design
I added dark mode to our creator tool. But this isn't about dark mode. It's about interfaces that help you focus instead of fighting for attention.
Design
No one notices these details unless they're wrong. But getting them right is what makes people stay.
Marketing
It was voice notes and shower thoughts. 7.84% CTR on pure, human copy. People want content tools that sound like them, not like software.
Strategy
Learn how to leverage voice technology and conversational AI to speak to tweet. Create authentic content with our voice interface that transforms speaking into social media posts.
Announcement
Introducing X11.Social - conversational AI that lets you speak to tweet. Call to tweet technology that transforms voice into engaging posts. The ultimate social media post scheduler with voice interface....
