What is Multichat?
Multichat lets you chat with many AI models simultaneously in side-by-side columns. Send one message, see how different models respond, and pick the best parts of each. It's like having your own council of experts. You can cross-validate answers and combine the strongest ideas.
What models do you support?
We support 50+ models across all major providers — Anthropic (Claude), OpenAI (ChatGPT), Google (Gemini), xAI (Grok), DeepSeek, Mistral, Kimi, Qwen, and more. New models are added regularly.
Why should I use PromptHQ over ChatGPT or Gemini?
ChatGPT and Gemini lock you into one provider. PromptHQ gives you all the top models in one place — premium and open source — so you can compare them side-by-side in Multichat and use Skills to get better results. You see which model actually works best instead of guessing.
Is it free?
At $3/mo it's almost free. You get access to 20+ smaller but capable models across all major providers, including some powerful open source models. And you get access to expert skills like Human Voice to make AI-generated content sound more real, a Resume Reviewer, an SEO expert, and many more.
What are Skills?
Skills are specialized AI capabilities that help models perform specific tasks better — like writing SEO content, drafting documents, reviewing resumes, doing competitive analysis and more. Simply select a skill before you send your question.
Is my information private?
Yes. We will not sell or distribute your data. You can share your data with people you choose through our collaboration features.
Do you train your LLM on my data?
No. We don't run our own LLM — we route your requests to the providers you choose (Anthropic, OpenAI, Google, etc.). Your data belongs entirely to you.
Why am I running out of usage?
Some models cost more than others. Claude Sonnet and GPT 5.4 consume more usage per message — especially in long conversations where the full history is sent each time. If your question doesn't depend on earlier messages, starting a new chat helps. Open-source models like Kimi and Qwen are much cheaper and great for everyday tasks. Your monthly usage is also allocated across the month so you don't burn through it all at once. If your allocation feels too restrictive, email us at help@prompthq.run and we'll work something out.
