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.
We support 45+ models across all major providers — Anthropic (Claude), OpenAI (ChatGPT), Google (Gemini), xAI (Grok), Perplexity, DeepSeek, Mistral, Kimi, Qwen, and more. New models are added regularly.
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, run structured Evals across models and prompts, and use Skills to get better results. You see which model actually works best instead of guessing.
Yes — there is a free plan where you get to try out Multichat (Skills included) and Evals with Lite and OpenSource models lile GPT 5 Mini, Gemini 2.5 Flash Lite, DeepSeek, Kimi, etc. Upgrade to use premium models (Gemini 3 Pro, Claude 4.5 Sonnet, GPT 5, etc), with more usage and available features.
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.
Yes. We will not sell or distribute your data. You can share your data with people you choose through our collaboration features.
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.
Evals let you systematically compare models, prompts, and settings. Run the same prompt across multiple models, tweak temperature or thinking budgets, and see structured results — so you can make data-driven decisions instead of relying on vibes.
PromptHQ.run is built by the team at GnoDesk. We built Multichat and Evals as internal tools to get better at using AI, and decided to make them publicly available.
