Questions & Answers

As answered by people managing Testsigma and cosskill.

What makes your product unique?

cosskill's answer:

Unlike general AI chatbots or character roleplay platforms, cosskill is purpose-built for practicing real-world difficult conversations. It offers 6 curated method personas โ€” each with a distinct communication framework, heuristics, and boundaries. You don't chat with a fictional character; you rehearse actual scenarios like salary negotiations, breakups, or workplace conflicts with a structured AI coach. No signup, no account, completely free.

Why should a person choose your product over its competitors?

cosskill's answer:

Most AI chat platforms (Character.AI, Replika, Chai AI) focus on entertainment or companionship. cosskill is the only tool specifically designed for conversation practice with real-world outcomes. Each persona follows a proven communication method โ€” not open-ended roleplay. There's no signup, no paywall, no content filters that block difficult topics, and no data collection. You get structured practice in seconds, for free.

How would you describe the primary audience of your product?

cosskill's answer:

Anyone facing a conversation they've been putting off. This includes professionals preparing for salary negotiations or difficult feedback, people navigating breakups or setting boundaries with an ex, job seekers rehearsing interviews or resignation conversations, and anyone who wants to build confidence before a high-stakes interaction. The audience ranges from young adults to working professionals across all industries.

What's the story behind your product?

cosskill's answer:

cosskill was born from a simple observation: people google "how to ask for a raise" or "how to break up with someone" millions of times โ€” but reading advice isn't the same as practicing it. We built cosskill to bridge that gap. Instead of just reading tips, you can actually rehearse the conversation with an AI that pushes back, challenges your approach, and helps you refine your words before the real moment arrives.

Which are the primary technologies used for building your product?

cosskill's answer:

osskill is built with Next.js 16 (App Router, React 19, TypeScript), deployed on Cloudflare Workers via OpenNext. AI responses are powered by large language models through OpenRouter, delivered via Server-Sent Events (SSE) for real-time streaming. Data is stored in Cloudflare D1 (SQLite). The frontend uses Tailwind CSS with a custom design system. Sessions are browser-local โ€” no user data is sent to external servers.

Who are some of the biggest customers of your product?

cosskill's answer:

cosskill is a free consumer tool โ€” we don't have enterprise customers in the traditional sense. Our users include:

Professionals preparing for performance reviews and salary negotiations People going through breakups who want to practice setting boundaries Job seekers rehearsing resignation or interview conversations Students practicing assertive communication Coaches and therapists who recommend it as a practice tool for clients
