CS Agent

The most capable option for customer service work. Excellent at reading long conversation histories, analyzing images (screenshots, product photos), and writing nuanced, context-aware replies. Recommended if you want the best quality responses.

💡 New accounts get free credits to start. After that, pay-as-you-go. Claude Sonnet 4 is the sweet spot of cost vs quality.

Google's AI with a generous free tier. Gemini 2.0 Flash is fast and capable — great for most customer service tasks. Free usage has rate limits (requests per minute/day) but is more than enough for testing and low-to-medium volume use.

💡 Gemini 2.0 Flash is free up to 1,500 requests/day — ideal for getting started at zero cost.

Groq runs open-source models (Llama, Mixtral) on custom hardware — the result is extremely fast responses, often 5–10× faster than other providers. Great for quick drafts. Free tier has daily token limits. Uses open-source models which are slightly less polished than Claude or Gemini for nuanced writing.

💡 Best if speed is the priority. Llama 3.3 70B is the recommended model — open-source but surprisingly capable for CS work.

A marketplace that gives you access to many AI models through a single API key — including free community-hosted models. This app currently uses only free models for OpenRouter, making it perfect for testing at zero cost. Quality varies per model; GPT-4o Mini is a reliable starting point.

💡 Sign up is free, no credit card needed for free models. Good for exploring different models before committing to a paid provider.
