DeepThink is Kiomi's deep research engine. It reads, weighs and stress-tests every answer before it speaks. A free Kiomi account is required. And because it's Kiomi, no topic is off-limits.
Breaks your question into what's actually being asked — including the part you didn't say out loud.
Pulls sources and evidence instead of vibing from memory.
Pits conflicting angles against each other. Keeps only the ones that survive contact.
Writes the full reasoning chain, not just the conclusion.
Attacks its own draft like a hostile reviewer. Patches the holes it finds.
Delivers the conclusion with the reasoning attached, so you can audit every step.
Controversial history, uncomfortable science, ethics debates with real stakes — most models blur into "it's complicated." DeepThink tells you what the evidence says, where experts disagree, and what it actually concludes.
Collapses, atrocities, failed states — analyzed with evidence, not etiquette.
Trolley problems with actual numbers. Debates where both sides have blood on them.
Competitor autopsies and business ideas reviewed like a hostile investor would.
Why it breaks, why it's slow, why your architecture is lying to you.
Psychology, manipulation, power dynamics — explained honestly, not prettily.
The findings nobody wants to summarize for you. Summarized anyway.
DeepThink needs a free Kiomi account. Thinking and Yurei both give you a few guest messages without signing in.
