Use tool ↗About Serno
Serno is a research workspace that answers a broad question by assembling three to five AI expert personas, each running on a different model among Claude, GPT and Gemini with its own brief, and having them argue out the contradictions before laying the result on a navigable canvas that can be shared or exported. Modes include a fast single-answer assistant, a quick multi-model Council verdict, deeper custom-team Canvas investigations and a claim-level Fact Check. The founders, Andrew Malouf and Amer Eid, went through Y Combinator in 2025; their YC profile now describes a recruiting product called Ovlo, and the Serno site sits behind a Cloudflare challenge that blocks automated reading, so how actively the product is maintained could not be confirmed.

Pros & cons of Serno
Serno's angle is running one hard question through several models playing different expert roles and showing where they disagree, which is a sound way to pressure-test a strategy decision. The problem in October 2026 is signal of life: the site blocks automated reading, and the founders' Y Combinator profile has been rewritten for a different company, Ovlo, a recruiting service. Try it only after the live site loads and the pricing page shows a current date or changelog.
Pros
- Runs the same question across Claude, GPT and Gemini rather than locking into one model
- Surfaces disagreement between models instead of hiding it behind one blended answer
- Canvas format is exportable and shareable, not just a chat log
Cons
- The vendor site could not be read today; price and feature claims rest on third-party listings
- The founders' YC profile now describes a different product, so continued development is uncertain
- Multi-model debate on every question is slower than a single-model chat for simple lookups
Best for
- Strategic questions that benefit from more than one model's perspective
- Teams that want a shareable map of an analysis rather than a chat transcript
Not for
- Quick everyday questions that do not need a multi-model debate
- Anyone building a workflow on a tool whose vendor status is unclear
Watch out: Confirm the product is still maintained before paying: the YC company page for Serno now redirects to Ovlo, and the site itself blocks automated verification.
