PromptQuorum

PromptQuorum is a browser-based tool for optimizing prompts, dispatching one prompt to 25+ AI models, and comparing the results with consensus and hallucination analysis. It supports cloud providers, local LLMs, and user-owned API keys.

What PromptQuorum is

PromptQuorum is a multi-AI prompt optimization and comparison tool that helps you write, refine, dispatch, and evaluate prompts across 25+ models. It is built around a browser-based workflow that keeps prompts and API keys under your control while you compare model outputs side by side.

The product’s core purpose is to make it easier to find the best answer for a task by combining prompt frameworks, iterative refinement, parallel model dispatch, and quorum analysis. The site positions it for users who want to check factual consistency, surface contradictions, and identify where a single model may be less reliable than a group of models.

Core features

Prompt frameworks for structured writing

Start from one of 9 built-in frameworks, including CRAFT, CO-STAR, RISEN, TRACE, APE, SPECS, Google Prompt, RTF, and Single Prompt Line, or use custom framework slots when you need a different structure.

Prompt optimization and refinement

Apply 8 one-click refinement types such as make concise, expand detail, break into steps, increase specificity, simplify, add quality controls, multi-expert consultation, and compress to essence.

Parallel multi-model dispatch

Send the same prompt to 25+ AI services at once, with a mix of auto-dispatch destinations and copy-paste destinations, so responses can be compared side by side.

Consensus and hallucination analysis

Review responses with 13 quorum analysis types, including consensus summary, contradiction detection, hallucination detection, confidence scoring, best answer selection, and weighted merge.

Browser-based privacy controls

Keep prompts and API keys in the browser, use your own API key or local LLMs, and avoid sending secrets to PromptQuorum servers.

Result export and sharing

Export results in multiple formats, including TXT, MD, JSON, CSV, HTML, and PDF, with download handled as a ZIP archive.

Practical use cases

  • Side-by-side model evaluation

    Compare several model outputs for the same prompt when you need to see which answer is most consistent or complete before using it.

  • Prompt drafting and iteration

    Refine a prompt with frameworks and one-click transformations when you want clearer instructions, better structure, or a tighter output shape.

  • Consensus and fact-checking

    Check whether claims are echoed across multiple models, especially when you want to spot contradictions or likely hallucinations in a response set.

  • Private or local workflows

    Use local LLMs or your own API keys when privacy or data control matters more than convenience, especially for sensitive prompts.

  • Result export and review

    Export multi-model results for review, handoff, or archiving when you need outputs in text, markdown, JSON, CSV, HTML, or PDF.

Pros and Cons

Pros

  • Combines prompt writing, refinement, dispatch, and comparison in one workflow.
  • Supports both cloud models and local LLM setups, which gives users flexibility over cost and privacy.
  • Keeps API keys in the browser instead of sending them to PromptQuorum servers.
  • Offers multiple analysis modes for checking agreement, contradictions, and hallucination risk.
  • Provides export options in several common file formats.

Cons

  • The current pricing page returns a 404, so pricing and launch status are not fully clear from the live site.
  • Most of the workflow depends on your own API keys or local models, so you need access to supported providers or local hardware to use the tool fully.
  • Several details are still presented as upcoming or waitlist-based, including desktop and web availability.

FAQ

Is PromptQuorum free to use?

Yes. PromptQuorum is described as free to use. The site says you can bring your own API key, use a local LLM, or try a limited free backend service for prompt optimization on a test basis.

How does privacy work?

PromptQuorum is designed to keep data under your control. The site says API keys stay in browser localStorage and are never transmitted to PromptQuorum servers, and you can also run it locally with tools such as Ollama or LM Studio.

Which AI providers are supported?

PromptQuorum dispatches prompts to 25+ cloud providers, including GPT-4o, Claude, Gemini, Mistral, DeepSeek, Grok, and others, and it also supports local LLMs such as Ollama, LM Studio, Jan AI, and GPT4All.

What platforms does PromptQuorum run on?

The site says PromptQuorum starts with desktop apps for Mac and Windows, followed by a web application and later mobile solutions.

What makes PromptQuorum different?

It is aimed at the full prompt lifecycle: writing with built-in frameworks, refining prompts, dispatching to multiple models, and analyzing the results for consensus and hallucination risk.
