LLMs Assemble

LLMs Assemble is a Chrome extension that transforms how you interact with Large Language Models by enabling you to orchestrate conversations across multiple LLMs simultaneously. Instead of manually copying prompts between different LLM platforms, switching tabs, and tracking responses in separate windows, LLMs Assemble acts as your productivity assistant—helping you broadcast questions and collect answers from ChatGPT, Claude, Gemini, and 9+ other leading LLM platforms from a single unified interface.

Independent Tool: LLMs Assemble is an independent productivity assistant that works across 25+ LLM platforms. We’re not affiliated with OpenAI, Anthropic, Google, or other platform providers—we’re a third-party tool designed to help you work more efficiently across platforms you already use. Learn more.

Early Access Program

This extension is currently in beta with controlled access. Request early access here.

We’re limiting initial access to ensure quality and stability. LLM platforms frequently update their interfaces—Claude might redesign their input field, ChatGPT might change their DOM structure, Gemini might alter their response format. By controlling our user base during beta, we can:

Beta access is completely free—we’re not charging for early access or implementing a paywall. We simply want to ensure the extension works flawlessly before opening to everyone.

After our initial testing phase (public release planned Q1 2026), the extension will become freely available to all users without authentication requirements.

Why Multiple LLMs Matter

r Each LLM has unique strengths, training data, and reasoning approaches. ChatGPT excels at creative writing and conversation. Claude provides nuanced analysis and detailed reasoning. Gemini integrates seamlessly with Google’s ecosystem. DeepSeek offers specialized technical knowledge. By querying multiple models simultaneously, you gain:

Core Actions

📢 Broadcast - Send Prompts to Multiple LLMs

Send the same prompt to multiple LLMs with a single click. Select which models you want to query (ChatGPT, Claude, Gemini, Grok, DeepSeek, Mistral, Copilot, and more), type your question once, and watch as LLMs Assemble assists by:

Perfect for research questions, creative brainstorming, technical troubleshooting, or any scenario where multiple perspectives add value.

🛍️ Collect - Gather Responses

Gather responses from different LLMs that you’ve already queried manually or through broadcast. The extension:

Once collected, you can paste the responses anywhere: into a text editor for manual review, into Google Docs for documentation, into an email for sharing, or back into an LLM use the Merge/Synthesize prompt template for further analysis.

Important: Only PINNED tabs are included in broadcast and collect operations. Standard workflow:

  • Keep multiple LLM platform tabs PINNED for broadcasting (ChatGPT, Claude, Gemini, etc.).
  • Keep one LLM platform tab as your CANVAS (unpinned).
  • 📢 Broadcast sends your prompt to all PINNED tabs.
  • 🛍️ Collect gathers responses from all PINNED tabs.
  • Use the CANVAS tab with 🔀 Merge or 🧪 Synthesize to combine the collected responses.

🔀 Merge Prompt Template

Generates a structured prompt containing your collected responses, instructing an LLM to combine them into one coherent document. The prompt guides the LLM to:

Ideal for research synthesis, creating comprehensive summaries, and building balanced documentation from multiple LLM perspectives.

🧪 Synthesize Prompt Template

Generates an advanced two-phase prompt containing your collected responses, instructing an LLM to integrate them into your existing document structure:

Perfect for iteratively building documentation, reports, or articles by gathering multiple perspectives and seamlessly incorporating them into your work.

Platform Compatibility

LLMs Assemble works with 25+ popular LLM chat and search platforms. Compatible platforms are automatically detected when you use the extension.

How It Works

The extension side-panel is organized into three sections:

Top Section: Tab Controls

Browser tab management for working with multiple LLM platforms:

Middle Section: Prompt Templates

LLMs Assemble follows prompt engineering best practices where effective prompts have 5 parts:

## Role
{Who the LLM should be}

## Context
{Background information}

## Objective
{What to accomplish}

## Process
{Step-by-step instructions}

## Format
{Output format, structure, tone, and style}

All templates copy to clipboard. Click any template to copy a pre-built prompt, then paste into your prompt area. Templates help you structure prompts before broadcasting to guide LLMs toward specific output types:

Privacy and Security

LLMs Assemble is built with privacy as a core principle:

Technical Details

How It Works: Automates manual browser actions (typing, clicking) using YOUR authenticated session. Does not maintain developer credentials, access platforms independently, or function when logged out.

Does Not Circumvent:

Graceful Failure: Stops functioning if platforms implement anti-automation measures—no bypass attempted.

Best Practices for Responsible Use

To minimize risk and ensure sustainable use of LLMs Assemble:

Platform Compatibility

LLMs Assemble works with 25+ LLM platforms. Each platform has its own Terms of Service regarding automation and browser extensions.

During setup, you’ll select which platforms to enable. Review each platform’s Terms of Service to make an informed decision about which platforms you’re comfortable using.

If you receive a platform notice: If any platform sends you notice that your use of browser extensions violates their terms, you must immediately cease using this extension with that platform. Continuing after receiving notice may constitute unauthorized access under federal law.

Respect Platform Rate Limits

Maintain Manual Oversight

Use as a Productivity Enhancement

Remember: This extension is your productivity assistant to enhance your workflow, not to abuse platform resources. Responsible use benefits the entire community by maintaining positive relationships with LLM platform providers.
