Build in Public Post Angle Generator
Describe the product, the audience, and the tension. OpenAI turns that into reusable post angles for X, LinkedIn, or a launch thread. If you already collect strong source material in bookmarks, this pairs naturally with TwitMix, which remixes bookmarked posts into fresh drafts.
AI output is generated on demand so the page stays static until you ask for it. For bookmark-based remixing instead of blank-page ideation, try TwitMix.
How it works
Your six inputs are sent to OpenAI through a serverless function, your API key is never exposed in the browser. The model generates multiple post angles shaped around your specific product, audience tension, and personal context. Copy the angles you like and adapt them for your platform of choice.

What should I post when building in public?
Post the thing you'd want to read if someone else was building your product. That usually means one of five angles: a real number (MRR, churn, signups), a decision you just made and why, a failure and what it taught you, a behind-the-scenes of how you built something specific, or a contrarian take on your niche. Skip the motivational quotes and the vague progress updates, they don't compound.
How do I write a build in public tweet that people actually read?
Lead with a specific number or specific detail in the first line. Cut the intro. One clear idea per post, not three. End with either a real question or a concrete next step, not a generic "thoughts?". Most build-in-public posts fail because they read like status updates instead of stories with tension.
How often should I post when building in public?
Three to five posts a week is the floor for the X algorithm to notice you. Daily is better if you can sustain the quality. The trap is posting daily with nothing to say, skip those days and ship a real update instead of filler. Consistency matters, but relevance matters more.
What's the difference between build in public on X and LinkedIn?
X rewards short, sharp, personality-driven posts with strong hooks. LinkedIn rewards slightly longer narrative arcs with a clear lesson at the end. Same raw angle, different packaging. This generator gives you angles you can re-cut for either surface.
I have bookmarks full of great posts, how do I turn those into my own posts?
That's exactly what TwitMix is for. It takes posts you've bookmarked on X and remixes them into original drafts in your own voice, no blank page, no copying. Pair it with this angle generator to go from raw inspiration to finished post in a few minutes.
How do I keep my build in public posts on-brand?
Pick a brand archetype and write every post in that voice. A Sage teaches in frameworks; a Rebel names what the niche is pretending not to see; a Jester keeps it under 20 words and weird. The free Brand Archetype Quiz gives you your archetype in under three minutes, and ReplyWisely keeps your replies on that same voice at scale.
