Poe vs Serno

Poe

Poe makes sense if you want to compare frontier models side by side without paying each vendor, and the custom-bot layer is a cheap way to publish a prompt as a product. The catch is the points meter: one subscription buys wildly different quantities of use depending on which bot you pick, and per-bot costs are Poe's to change, so the plan you buy is not necessarily the plan you keep.

Pros

• +One subscription spans models from several vendors plus image and video generators
• +Custom bots can be built from a prompt and shared or monetised
• +Apps on web, iOS, Android, Mac and Windows
• +A creator API exists for developers

Cons

• −Points pricing makes real capacity hard to predict across models
• −Per-bot point costs and allowances are set by Poe and change over time
• −The home page blocks automated access and the subscription page shows regional prices, so USD figures could not be confirmed from the vendor
• −No team or enterprise tier is visible

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
