Main conversation
I'm building a dashboard component but the stats panel overflows on smaller screens. How can I fix this?
Here's a solution using CSS Grid with minmax() for responsive layouts without overflow.
display: grid; grid-template-columns: 1fr 300px;Side thread
“Here’s a solution using CSS Grid...”
Can we use Flexbox instead?
Yes, use flex-wrap with flex-basis...
Main thread stays clean while you explore tangents in side threads
How it works
Three simple principles for better thinking
Keep your main thread clean
Stay focused on your primary question without interruptions. No clutter, no distractions.
Ask side questions freely
Explore tangents without cluttering the main conversation. Branch naturally as you think.
Think in structure
Organize complex ideas naturally as you go. See connections between threads at a glance.
Built for deep work
Perfect for people who think deeply and ask many follow-up questions
Developers
Debug code, explore API alternatives, and understand complex architectures without losing context.
Founders & Builders
Pressure-test ideas, weigh trade-offs, and think through decisions in parallel — before you commit time or money.
Designers
Explore design decisions, ask "what if" questions, and iterate on ideas systematically.
Learners
Study a new subject, branch into follow-up questions as they come up, and keep your topic research organized so ideas connect instead of getting lost.
