About Cergai (/sɜːrˈɡeɪ/)
Multi-model AI synthesis for people who want one honest answer, not four hedged ones.
Last updated: May 18, 2026
What Cergai Is
Every major AI model will confidently give you a different answer to the same question. ChatGPT leans one way, Claude another, Gemini a third, Grok a fourth. If you only ask one, you get one model's priors dressed up as the truth. If you ask all four, you get four contradictory paragraphs and no answer.
Cergai queries four frontier models in parallel, then uses an independent fifth model to synthesize what they actually said into a single verdict. When the four agree, you get a direct answer. When they split, Cergai tells you exactly where and why — no fake middle, no editorializing.
The product is built around one idea: the interesting signal is in convergence and divergence between independent AI architectures. That's what we surface.
The Models
Four independent frontier models run every query in parallel. Each is queried with the same question and no knowledge of the others' answers.
Cergai's only job is to read the four responses and write the verdict. It is deliberately not one of the four — using any of them to synthesize their own output would bias the verdict toward that model's priors.
Cergai is open-weights and runs on our own infrastructure, so there's no hidden editorial layer from a major lab between you and the verdict.
Search
Type any question — factual, forecast, contested, weird. Cergai runs all four models on it in parallel and shows you one synthesized answer plus a full breakdown of where each model stood.
On every result you'll see:
- A verdict — one direct answer in two or three sentences.
- A convergence score (0–100%) showing how tightly the four models agreed, along with a tier label (Strong Consensus, Broad Agreement, Split Views, or Sharp Divergence).
- A Point-by-Point Breakdown table listing the key claims and which of the four models supported each.
- A Where They Agreed and Where They Diverged section so you can see the texture of the inter-model signal.
- Reading Recs — relevant articles you can jump to for deeper context.
- The four raw perspectives — each model's untouched answer if you want to read it directly.
The convergence score
Every result is tagged with a convergence percentage and a tier:
High convergence means the models agreed — not that they're necessarily right. Cergai surfaces inter-model signal; you still think.
Newsletters
A daily brief that runs the same multi-model pipeline on the stories that matter in your verticals, delivered to your inbox each morning.
Standard newsletters
Curated topic feeds — Global Politics, Markets, Tech & AI, Sports, Science & Health, Health & Medicine, Law & Policy, Film & Media, Business Strategy. Each runs a tight prompt on the cadence that fits the vertical. Free users get one; Pro unlocks the full set.
Custom newsletters (Pro)
Build your own: add 1–3 prompts, pick a title, any days of the week, any time. Cergai delivers the verdicts at your chosen time.
SMS delivery for newsletters is coming soon — we're finishing carrier approval.
Research Threads
A research thread is a persistent, named collection of Cergai analyses that build on each other. Save any result to a thread, ask the next question, save that too — the thread keeps your queries linked so you can come back and see the bigger picture.
Threads are attached to your account and private by default. Free users get a small number of threads; Pro removes the cap.
The Game
A card-swipe game where Cergai shows you a real synthesized result and asks: did the four models agree or split on this one? Guess, then see the actual convergence score and which models sat where.
The game uses real Cergai results — filtered to keep things high-signal. We exclude newsletter-generated searches, anything with personal information, and adult content. Build a streak, climb the leaderboard, and develop a feel for where AI models tend to agree and where they don't.
Messages
Cergai has built-in direct messaging — any user can message another user. Useful for sharing a specific analysis, pinging a research thread, or just chatting about something you both searched. Messaging is strictly opt-in: no one can DM you unless you've allowed it in account settings.
Privacy & Data
Cergai stores your queries, your results, and (if you've saved them) your threads. Queries are not sold or shared for advertising. Phone numbers — for SMS notifications — are only shared with Twilio for delivery, never with third parties for marketing.
