Decidi vs. Perplexity
Cited answers from the web, or a council that reviews your own work.
Decidi vs. Perplexity: the short answer
Perplexity is an AI answer engine: ask a question and it searches the web and returns a synthesised, cited, up-to-date answer. Decidi does a different job — it doesn’t browse the web to answer a question, it convenes a council of frontier models and expert personas to review, debate and improve work you bring it (a contract, a pitch, code, a plan), then reviews the verdict with a Final QA audit and hands you a downloadable deliverable. Use Perplexity to research a question; use Decidi to review and decide on your work before you ship it.
What Perplexity does well
Perplexity is one of the best tools for fast, trustworthy research — it pulls real-time information from across the web and shows its sources, so you can chase down where an answer came from. For “what’s the answer to this question,” it’s excellent.
Where Decidi is different
They solve different problems. Perplexity answers questions from the public web; Decidi reviews the specific work you give it. Where Perplexity cites sources for a fact, Decidi runs several independent models that challenge each other on your draft, surfaces where they disagree, and audits the verdict before you act — and returns a finished deliverable, not a reply.
The difference that matters most: an always-on Final QA audit reviews every verdict against known AI failure modes before it’s final — so you act on a result that’s been checked, not just generated. See the Trust Stack →
