Thinkbase
The first opinion market
Free · Designed for iPhone. Not verified for macOS.
Where opinions meet accountability.
Thinkbase is the world's first opinion market — where people debate the questions that matter, then put their credibility on the line. Vote on trending debates, back your opinions with points, argue your position, and climb the leaderboard as the world proves you right (or wrong).
VOTE ON LIVE DEBATES
Browse debates across politics, sports, technology, culture, science, and philosophy. Cast your vote on any question and watch real-time trend charts shift as the crowd weighs in. See how opinion changes over time with live-updating vote percentage charts.
BACK YOUR OPINIONS WITH POINTS
Think you know what's coming? Back your opinion with points. Commit to debate outcomes and watch your accuracy build over time. Earn credibility for correct calls, lose it for wrong ones. Your track record follows you.
ARGUE YOUR POSITION
Every debate has a threaded argument feed. Post your take, reply to others, and upvote the strongest arguments. Filter by answer option to see all sides. Build your credibility through thoughtful analysis — not just hot takes.
TRACK YOUR ACCURACY
Your portfolio shows every opinion you've backed — active positions, settled outcomes, and the debates you've created. Points wagered, points earned, win/loss record. No hiding from your track record.
CLIMB THE LEADERBOARD
Weekly, monthly, and all-time rankings. Your credibility score reflects opinion accuracy over time. The sharpest minds rise to the top. Compare against friends or the entire community.
DISCOVER WHAT'S TRENDING
Personalized "For You" recommendations powered by your voting history. Semantic search finds debates by meaning, not just keywords. Category filters let you dive into what interests you. Live tab shows debates about to close — last chance to weigh in.
CREATE YOUR OWN DEBATES
Ask anything. AI processes your question into a structured debate with answer options, reviews it against community guidelines, and publishes it in seconds. Set custom durations from minutes to months.
REAL-TIME EVERYTHING
Votes update across all screens instantly via live streaming. Trend charts animate as new votes arrive. Arguments appear in real-time. The app feels alive because it is.
