In this post I’m going to walk you through Google’s brand-new AI agent builder, Opal — the free, no-code tool that lets you build, edit, and share mini AI apps to automate repetitive work using plain English. I created a full video demo of Opal and its wild possibilities, but here I’ll break everything down in written form so you can use it as a step-by-step guide, a list of real-world use cases, and a resource to start building your own AI-powered workflows today.
Opal (accessible at https://opal.withgoogle.com) changes how we think about automating knowledge work. Instead of writing multiple prompts to a single LLM or cobbling together complex Zapier flows, you tell Opal in natural language what you want and it builds a mini app that runs the entire process — from collecting inputs to researching, generating content, creating images, and formatting outputs. It’s beginner-friendly, free, and you don’t need to know how to code.
Below you’ll find a clear breakdown of what Opal is, how it works, step-by-step instructions to build your first agent, five high-impact use cases you can start using today, best practices, limitations, ethical considerations, and an FAQ to clear up anything you might be wondering. I’ll also share the special AI training I partnered with OutSKILL to offer if you want to go deeper and future-proof your career.

What is Opal (Google’s AI Agent Builder)? 🤖
Opal is a visual, no-code builder from Google that lets you assemble mini AI “apps” (agents) using natural language instructions. Think of it as a combination of a chatbot, workflow editor, and app builder — but focused on automating knowledge tasks like writing, research, content generation, and simple decision-making.
Key characteristics of Opal:
- No code required: You describe your desired app in plain English, and Opal constructs the steps, inputs, and outputs for you.
- Integrated assets: Upload files, connect Google Drive, pull content from YouTube, include text or drawings — Opal can use these assets as part of the workflow.
- Multi-step workflows: Each agent can run a sequence of steps: research, generate text, create image descriptions, produce images, and format the final output.
- Preview and console: You can preview the app, test it, and view a console of intermediate steps so you can debug or improve the agent.
- Shareable: Once built, agents can be shared with others so your team can reuse or iterate on them.
Opal is designed for real-world productivity improvements. Instead of manually running multiple prompts or copying outputs between tools, you can build a single agent that runs the entire process end-to-end. That’s what makes it a game-changer for content creators, marketers, educators, and teams that want to automate repetitive tasks.
How Opal Works — A Step-by-Step Walkthrough 🛠️
I’ll walk you through the exact steps I use when creating an Opal agent. The process is intuitive, and Opal even displays a progress bar and step list so you always know what’s happening.
Step 1 — Create a New App
From the Opal homepage, click “Create new.” You can either manually add inputs, outputs, and assets, or simply type what you want the app to do. For example, I typed:
“I want to build a tool that writes blog posts for me after I give it the topic. It should do all of the research needed, then write and format a blog post and create an image for the blog post.”
Opal took that instruction and scaffolded the app automatically — adding input fields for the topic, steps to conduct research, generate content, create an image description, generate the image, and format the blog post.
Step 2 — Configure Inputs & Assets
Inputs are the variables your agent needs: a topic, a product URL, a YouTube link, or a photo. You can upload files from your device, pull files from Drive, or give it a YouTube URL to extract transcripts. This makes it easy to create agents that use your existing assets.
Step 3 — Define Steps and Outputs
Opal’s workflow UI will show each step it plans to execute. Typical steps include:
- Research: gather facts and context from the web or supplied assets.
- Generate: create copy, headlines, captions, or scripts.
- Create an image description: describe an image to be generated.
- Image generation: produce an image based on the description.
- Format: assemble the final deliverable (blog post, social post, video script).
You can preview each step, view the console to see intermediate outputs, and adjust the theme or UI of the app before you publish it.
Step 4 — Preview, Test, and Share
Once the agent is built, click “App” to preview and test it. Enter a sample input (like “voice AI agents” for a blog topic) and watch the agent run. Opal displays progress and shows the steps it’s running — so you never have to guess how long it will take.
When you’re satisfied with the agent, you can share it with others or use it directly to automate tasks.
Five Insanely Useful Use Cases You Can Build Today 🌟
Now for the fun part: real, actionable use cases you can replicate immediately. During my demo I built several agents live — here are five high-impact processes you should try.
1. Social Media Post Generator for Businesses 📣
Use case summary: Upload your business URL and assets, describe the proposed post (promotion, community outreach, event), and Opal will produce the caption, visual, hashtags, and suggested platform sizing.
Example setup I used:
- Input: Business URL (I used a sample site, “Baseball Lifestyle 101”).
- Post focus: “Labor Day 40% off sale.”
- Asset: Brand logo uploaded from my device.
Results: Opal generated an on-brand caption (“Swing into savings this Labor Day — 40% off!”), a suggested visual (banner or product shot), and a set of smart hashtags relevant to the niche. The agent even recognized the baseball context and used baseball-themed wordplay like “Swing into savings.”
Pro tips:
- Specify the platform (Instagram, Facebook, LinkedIn) so Opal formats the image size correctly (square, landscape, etc.).
- Provide a product image for product-focused posts so the generated creative is on-target.
- Tweak hashtags and tone to match your brand voice.
2. AI Video Ad Creator for Marketers 🎬
Use case summary: Input a product name and target audience, and Opal will research the product, extract key specs and value propositions, and produce a short video ad complete with visuals and script.
What I tested: I first tried a product that included minors (children’s shorts), and Opal refused — it blocks video generation that depicts minors. That’s an important safety limitation to remember. I then switched to a luxury product (“2018 Ferrari 488 Spider — white”) with target audience “rich people who love cars.” Opal produced a convincing ad concept: visuals of a white Ferrari, a suited narrator, and a luxury-focused script — usable as a social ad or landing page hero video.
Pro tips:
- Avoid uploading content that includes minors for video generation due to safety restrictions.
- For product ads, provide product pages or top selling product links to help Opal pull accurate specs.
- Iterate on the tone: “sporty,” “luxury,” “budget-friendly” — these tweaks change the ad’s messaging dramatically.
3. Turn Any YouTube Video Into an Interactive Quiz 🎓
Use case summary: Paste a YouTube URL, let Opal extract the transcript, and it will analyze the content to create an educational report and an interactive quiz. This is a powerful way to convert passive content into active learning material.
My test: I used one of my own YouTube videos. Opal pulled the transcript, created a structured educational summary with key learning points and segments, and generated a quiz with questions that reinforced the video’s main ideas.
Why this matters:
- Teachers can turn lecture videos into quizzes for students.
- Content creators can increase engagement by including interactive learning elements.
- Businesses can train employees by converting explainer videos into testable learning modules.
4. Blog Post Writer — Research, Draft, and Image Creation ✍️
Use case summary: Provide a blog topic and Opal will research, draft, create an image description, generate the blog image, and deliver a formatted blog-ready post.
What this accomplishes: Instead of running separate research and writing prompts, Opal runs the entire chain — research to image — producing a draft that is “draft ready” for WordPress or your CMS. You can even instruct it to optimize for SEO or produce a post that’s ready to publish.
Workflow highlights:
- Input: Blog topic (e.g., “Voice AI agents”).
- Step 1: Research relevant sources and compile notes.
- Step 2: Draft the blog post with subheaders, intro, and conclusion.
- Step 3: Generate an image description and produce a custom image.
- Step 4: Deliver formatted post ready for copy/paste or export.
Pro tips:
- Ask Opal to include SEO elements like meta description, suggested keywords, and headings.
- Review references if citations matter — Opal’s research summary can include links or source attributions if you request them.
- Customize voice and length: “Write in a friendly, authoritative tone, 1,200–1,500 words.”
5. Business Profile, Product Research, and Creative Tools — Everything Else 🚀
Use case summary: Opal isn’t limited to content. The platform includes templates or agents for:
- Business profile audits — shows how the internet currently represents a company or brand.
- City builder — create a game concept with AI-generated visuals.
- Product research — analyze market fit and competitor insights.
- Spelling bee or quizzes — for classrooms and learning communities.
- Fashion stylist — outfit suggestions based on uploaded images or style preferences.
- Generated playlists — mood-based music suggestions
You can imagine building hundreds more agents. Because Opal accepts plain English, the only limit is your imagination. Build a hiring screener, an onboarding helper, a weekly newsletter generator, a meeting notes summarizer — the list goes on.
Best Practices and Prompt Tips ✨
To get reliable, repeatable results from Opal, follow these practical guidelines I use every time I build an agent:
- Be specific about the output format: Tell Opal whether the result should be “an Instagram caption under 150 characters” or “a 1,200-word blog post with H2 headings and meta description.” Specificity reduces iteration time.
- Supply assets: Give brand logos, product images, or example content so the agent can match your brand voice and visuals.
- Test with real inputs: Use actual product pages, real YouTube URLs, and real topics. This reveals edge cases and improves the agent’s reliability.
- Use the console: The step console is gold — it shows what the agent did at each step and makes debugging simple.
- Iterate the flow: If a step needs refinement, edit the instruction for that step rather than rebuilding the whole thing.
- Prompt-engineer for tone: Add phrases like “use friendly, conversational tone” or “use professional B2B tone” to control voice.
Limitations, Safety, and Ethical Considerations ⚖️
While Opal is powerful, it’s not perfect and comes with important constraints and responsibilities:
- Safety filters: Opal blocks certain content categories, such as video generation involving minors. Respect these guardrails.
- Accuracy and citations: Agents can summarize and synthesize information, but you should verify factual claims, especially in regulated domains like medical, legal, or financial content.
- Bias and hallucination: Like any LLM-powered system, outputs can reflect biases or invent details. Use human review for critical content.
- Privacy: When uploading proprietary or customer data, be aware of where that data is stored or how it’s processed. Check Google’s terms and your organizational compliance policies.
- Job displacement concerns: Automation may change job roles. Instead of fearing displacement, focus on using tools to elevate your productivity and develop AI literacy — that’s how you remain indispensable.
As I said in the demo during the video, “If you don’t want to do this manually, you could literally just tell us exactly what you wanna build.” That convenience is incredible, but it also means builders must be thoughtful about how they automate tasks and how they validate outputs.
How This Changes Work — Opportunities, Not Just Threats 💼
There’s a lot of talk about AI replacing jobs — and the data shows some roles will be transformed. Companies like Amazon, JP Morgan, and Ford have already adjusted headcount in response to automation trends, and larger tech companies have made public estimates about workforce impacts. But there’s another side to this story: people who learn to leverage AI will be more competitive.
Here’s how you can turn automation into opportunity:
- Upskill with intent: Learn core skills like prompt engineering, agent design, and AI-based automation.
- Focus on value-added work: Use AI to handle repetitive tasks, freeing you to handle strategy, relationship-building, and complex problem solving.
- Build AI-enabled products: Automations can become products or services you sell to clients, from content-as-a-service to automated ad generators.
- Teach and lead: Teams will need people who understand how to safely deploy and monitor AI systems.
To help with that, I partnered with OutSKILL to offer a free two-day AI Mastermind that teaches the exact skills you need — prompt engineering, top tools, AI-driven Excel and presentations, and how to build agents like the ones I demonstrate here. There are free seats available and bonuses for attendees, including a prompt bible with thousands of prompts and a personalized AI toolkit builder if you attend both days.
Suggested Multimedia and SEO Enhancements 📸
