Barayand

The idea

Barayand is the Persian word for a resultant: the single vector you get when several forces are added together. That is the product. Instead of trusting one model, you send a question to a panel of the world’s leading models at once. A judge model reads all the answers and extracts where they agree, where they diverge, what only one of them noticed, and what all of them missed. A synthesizer then writes one grounded answer, with an agreement score attached, so you can see how much to trust it.

The idea came from a simple observation: every model is confidently wrong sometimes, and no single one is right all the time. Disagreement between models is not noise. It is signal, and Barayand turns it into a product.

What shipped

I started building it in June 2026 and shipped it the same summer as a Persian-first platform: chat with any model, image generation, long-term memory, web and deep research, gift subscriptions, local pricing, and phone login. Two assistants sit on top of it. Hambonyan (هم‌بنیان) turns a business idea into a workspace, runs the playbooks for customers, market, competitors, and unit economics, and ends with a board review where a panel of models argues against the idea before it gets a verdict. Hamfekr (هم‌فکر) guides a research project from question to defense, keeping the writing in the author’s hands.

The benchmark

Alongside the product, I published an open, reproducible benchmark for Persian: 300 questions across 10 axes, deterministic scoring with bootstrap confidence intervals, and reference results from the leading models. The Persian-speaking world needed a shared yardstick, so I built one.

I designed and built Barayand alone, from the brand mark to the billing.
