Questions & Answers

As answered by people managing StackMail and FeelPair.

What makes your product unique?

FeelPair's answer:

Both partners join the same chat and the AI mediates the actual conversation live — it is not a coach you talk to alone, and not a set of prompts you read together. It de-escalates in real time, translates a complaint into the need behind it, and helps the couple land one concrete agreement. Each partner also has a private space the other never sees. It works in 10 languages and can be tested without creating an account.

Why should a person choose your product over its competitors?

FeelPair's answer:

Most couples apps are built for daily connection: check-ins, quizzes, prompts, or one-sided coaching. FeelPair is built for the moment the conversation is going badly — both people in one chat with a neutral third voice in the middle. It is also honest about payment: free to try with no account, a one-time $29 Conflict Episode instead of a subscription you must remember to cancel, and $99/year only if you want continuity. If a situation needs professional care, FeelPair says so — it does not present itself as therapy.

How would you describe the primary audience of your product?

FeelPair's answer:

Couples in the middle of a specific conflict — the argument that keeps repeating, the topic no one knows how to raise, the silence after a fight — who want help now rather than a weekly routine. Many arrive when professional counseling is out of reach for cost, scheduling, or because one partner will not go. Used most in Spanish and English, on mobile, and often started by one partner who then invites the other.

What's the story behind your product?

FeelPair's answer:

FeelPair started from a simple observation: most couples do not break up over one dramatic event, they erode in ordinary conversations that go wrong — where one person attacks and the other withdraws, and both end up feeling unheard. Professional help exists but is expensive, slow to book, and often refused by one of the two. So we built the missing piece: a neutral voice present in the moment the conversation happens, mediating between both people instead of advising one. It is built by a small independent team in Montevideo, Uruguay.

Which are the primary technologies used for building your product?

FeelPair's answer:

Laravel (PHP) with MySQL on AWS, Blade and Alpine.js on the front end, Tailwind CSS. Conversations are mediated by large language models (OpenAI and Anthropic) through a custom mediation layer that keeps context per couple. Twilio for the WhatsApp channel, Resend for transactional email. Conversations are not used to train AI models.

Who are some of the biggest customers of your product?

FeelPair's answer:

individual couples, not organizations. We do not disclose users — privacy is the core of the product.
