What is Opal and why it matters 🤖

Opal (access it at opal.withgoogle.com) is Google’s free, beginner-friendly platform for creating mini AI apps — think small, focused tools that automate a specific task using large language and multimodal models. Instead of sending one-off prompts to a chat model, Opal lets you assemble a chain of steps: collect inputs, research, generate text or images, format outputs, and display them in a shareable interface.

Key takeaways:

How Opal works — step-by-step 🛠️

At its core, Opal turns a natural-language prompt into an executable template of steps. Here’s a simplified flow that I used live in the demo:

  1. Click “Create new” and either choose a template or describe what you want the app to do in plain English.
  2. Add user inputs (e.g., topic name, product URL, YouTube link).
  3. Add steps where things will be generated — research, draft content, create image prompts, or make a formatted output.
  4. Attach assets (upload files, connect Google Drive, input text or drawings, include YouTube video links).
  5. Preview and test the app. The console and progress bar show exactly what is happening in real time.
  6. Edit the theme, tweak prompts or steps, then share or export the resulting output.

Opal gives you visibility into the process: a progress bar that shows each subtask (research, generate, render), a console that lists the steps and intermediate results, and an app preview where you can interact with the finished interface. That transparency makes it easier to debug, refine prompts, and hand the app to others.

Live example: Build a blog post writer 📝

One of the first demos I built was a mini-app that writes blog posts from a topic. Instead of manually researching and prompting the model multiple times, I set up Opal to chain these steps:

What impressed me most is how quickly Opal built this app. In seconds, the platform generated a title, created the image, and delivered a draft post that was ready for light editing. Rather than juggling multiple prompts in Gemini or ChatGPT, you now encapsulate the entire workflow in one mini-app — perfect for content teams, freelancers, or solo creators who need fast draft-ready material.

Use Case 1: Social media post generator 📱

One of the first practical builds I demonstrated was a social media post generator tailored to a business’ website and campaign. The workflow looked like this:

  1. Input: Provide the business URL (Opal crawls and summarizes the site).
  2. Campaign brief: Tell the app the proposed focus (e.g., “Labor Day 40% off sale”).
  3. Assets: Upload a logo or product image to include in the creative.
  4. Generation: Opal creates a caption, a social creative, suggested image text, and a set of platform-appropriate hashtags.
  5. Output: A ready-to-post package (text + image) which can be previewed and adjusted.

In my demo I used a baseball apparel website and uploaded the logo. Opal generated a fun, niche-aware caption: “Swing into savings this Labor Day — 40% off!” The hashtags were contextually relevant, and the image text looked suitable for a banner — though I noted you should specify the social platform (Instagram square vs Facebook landscape) to get the correct dimensions up front.

Why this is useful:

Use Case 2: AI video marketer 🎥

Another powerful application is building short video ads for products. Opal can:

During the demo I attempted to create a product video for children’s apparel and encountered an important safety constraint: Opal’s video generation with minors is not supported. This is a crucial content policy to respect. I then switched to a different product (a 2018 Ferrari 488 Spider) and Opal generated a convincing short ad concept featuring a suited driver and the white Ferrari — impressive for a single automated run.

Practical tips for video marketers:

Use Case 3: Turn YouTube videos into quizzes and learning reports 🎓

One of my favorite creative uses is converting existing video content into an interactive learning tool. The Opal workflow for this looks like:

  1. Input a YouTube video URL.
  2. Opal extracts the transcript and segments the video into key learning points.
  3. It generates an educational report and an interactive quiz (multiple choice or true/false) to reinforce learning.
  4. Result: A study/teaching tool that helps viewers retain the information from the video.

I demoed this with one of my own YouTube videos — Opal created an “educational report” with key takeaways and a quiz to test comprehension. If you’re a creator, teacher, or course designer, this is gold: you can repurpose a single video into a lesson module with zero manual script-writing.

Ways to use this in practice:

Other powerful use cases 🔥

Opal isn’t limited to content and marketing. During the demo I also highlighted several other templates and ideas that show how flexible the platform is:

Because Opal builds mini apps via natural language, the possibilities are nearly unlimited. You describe the workflow in plain English, and Opal creates the steps, wires the inputs and outputs, and packages the UI for sharing.

Key features and UX highlights ✨

During my walkthrough there were a few UX elements that stood out as especially useful:

Limitations, safety, and best practices ⚠️

While Opal is powerful, there are important constraints and best practices to keep in mind:

Why this matters — AI and the future of work ⚖️

AI is changing how white-collar work gets done. In the demo I referenced widespread changes across industries — companies like Amazon, JP Morgan, and Ford have made headlines for workforce changes influenced by automation. Microsoft has published internal estimates indicating significant workforce impacts from AI tools. Those headlines can be scary, but they also show an opportunity: learning to build and use AI tools can make you more valuable, not replaceable.

My personal recommendation is to treat tools like Opal as productivity multipliers. If you learn how to automate repetitive tasks, you will free up time for higher-value strategy, creativity, and relationship work. To help with that transition, I partnered with OutSKILL to offer a free 2-day AI Mastermind training that covers prompting, tools, automations, and agent development — the goal being to give hands-on skills that future-proof careers.

FAQ ❓

Q: What is Opal and how is it different from ChatGPT or Gemini?

A: Opal is a no-code platform from Google that assembles multi-step workflows into shareable mini apps. While ChatGPT and Gemini are conversational models that respond to prompts, Opal uses models under the hood and combines them with logic, assets, and UI to create repeatable apps (e.g., a blog writer, a video ad generator, or a quiz maker). Think of Opal as the app-builder that orchestrates AI tasks in a structured way.

Q: Is Opal really free and who can use it?

A: Opal was released as a free builder. Anyone with access to the platform (via opal.withgoogle.com) can create, edit, and share apps. Be sure to review any usage limits and data policies in your account settings as Google may have quotas or premium features later on.

Q: Do I need coding experience to use Opal?

A: No. Opal is designed for non-technical users. You describe what you want in plain English, add inputs/assets via the UI, and Opal constructs the steps for you. That said, basic familiarity with how prompts influence outputs will help you get higher-quality results faster.

Q: What are the most productive use cases for small businesses?

A: High-impact, low-complexity tasks work best at first: social media caption generation, product ad storyboards, blog post drafts, automated customer response templates, and content repurposing (e.g., turning blog posts into social content or video transcripts into quizzes).

Q: Are there safety or content restrictions?

A: Yes. Opal enforces content policies — for example, generating videos that include minors may be disallowed. The platform will also prevent certain types of harmful or illegal content. Always review the console logs and policy warnings during generation.

Q: Can Opal integrate with other systems (like WordPress or Slack)?

A: Opal currently focuses on app creation and content generation. You can export generated content manually, and share apps with collaborators. For deep integrations (e.g., automated posting to WordPress or Slack), you may combine Opal with automation platforms (like Make or Zapier) or use built-in connectors if Google adds them.

Q: How do I ensure generated facts are correct?

A: Treat AI-generated research as a first draft. Verify any factual claims, citations, or figures before publishing. For critical content, add a final human review step in your Opal workflow — for instance, generate the post but require a team sign-off before publishing.

Q: Can I monetize Opal apps or sell templates?

A: Many creators use Opal-built apps as internal productivity tools or client deliverables. If you plan to commercialize templates or outputs, check Opal’s terms of service and Google’s policies to ensure compliance. Consider packaging templates as training assets, workflow blueprints, or managed services for clients.
