Yazero

Yazero Validator exists for the stage before you build anything: the pile of ideas you have been carrying around without knowing which one deserves your time. Instead of a blank chat prompt, it gives you a structured workflow — describe the idea, hit validate, and receive a written analysis covering the market, the competition, who the customer is and what problem the product actually solves. The run takes about 30 seconds and the full output is saved to your profile so you can revisit or compare it later.

The technical difference Yazero claims is architectural rather than cosmetic. It gathers data from multiple sources through scraping and APIs, routes different tasks to different large language models based on their individual strengths, and applies retrieval-augmented generation and chain-of-thought prompting to improve accuracy. Crucially, it normalises the output so different ideas can be compared against consistent, quantifiable feedback — which is hard to do with free-form chatbot answers.

Validation is credit-based, with 3 free credits on signup and basic validation costing 1 credit. An advanced tier adding Reddit, App Store, technical and investor analyses is described but not yet live. Sharing to the community is optional and genuinely optional in the privacy sense — unshared ideas stay private, even from Yazero. If you come to it with nothing, you can also browse the community feed to see what other founders are working on.
