Opal AI test-launched by Google: Here's how it can generate apps without coding, with a simple prompt
The tool, now accessible in the United States via Google Labs, is the latest in a growing wave of so-called "vibe-coding" platforms targeting both developers and non-technical users, as reported by TechCrunch.
Opal enables users to either start from scratch using text-based instructions or customise existing apps from a shared gallery. Once a prompt is submitted, Google's internal models generate the application's structure.
Users are then presented with a visual workflow panel that outlines each step in the process - including input, output, and generation phases.
🚨 NEW LABS EXPERIMENT 🚨
Introducing Opal, our new way to help you build and share AI mini-apps by linking together prompts, models, and tools— all while using simple, natural language (without a single line of code 🤯)
Now available in US-only public beta! Learn more ⬇️… pic.twitter.com/9Csk1EruJu — Google Labs (@GoogleLabs) July 24, 2025
Each stage can be clicked to reveal and edit the underlying prompt, while additional steps can be added manually through Opal's toolbar. Finished applications can be published online and shared via a direct link, with others able to test the app using their own Google accounts.
While Google already offers an AI Studio for developers to build apps through prompt engineering, Opal appears to mark a broader push towards accessibility and design-driven prototyping.
Its visual-first interface and ease of use suggest the company is aiming to appeal to hobbyists, creatives, and aspiring app builders without coding experience.
The move brings Google into direct competition with companies such as Canva, Figma, and Replit, all of which have introduced tools that lower the barrier to entry for software creation.
Startups in the space, including Lovable and Cursor, have recently drawn significant investor and acquisition interest amid rising demand for generative AI solutions.
Opal is currently in an experimental phase and forms part of Google's wider efforts to test emerging AI technologies through its Labs division.

KSE-100 hits all-time high as investors cheer US tariff reduction
Buying momentum was seen at the Pakistan Stock Exchange (PSX) on Friday as investors celebrated the reduction in US reciprocal tariffs on Pakistan, with the benchmark KSE-100 Index closing the session at over 141,000 for first time in history. The bulls largely remained dominated in the last session of the week, pushing the KSE-100 to an intra-day high of 141,160.93. At close, the benchmark index settled at 141,034.99, up by 1,644.56 or 1.18%. 'This positivity in market can be attributed to news that Pakistan secured 'landmark' tariff deal with US, wherein Pakistan will now face reciprocal tariffs of 19% compared to earlier rate of 29%,' brokerage house Topline Securities said in its post-market report. 'Apart from this noise in the market that government will make payment to clear circular debt in coming weeks by obtaining Rs1.25 trillion from banks, provided stimulus to the market.' Top positive contribution of 1,355 points to the index cumulatively came from OGDC, PPL, HUBC & PSO, as they stand to benefit for circular debt payment, Topline said. 'Potential US-Pakistan collaboration on oil exploration and news regarding Circular Debt payment likely in next week provided much needed impetus to energy sector stocks today,' Ali Najib, Deputy Head of Trading at Arif Habib Ltd, said in a report. In a key development, the US administration imposed a 19% reciprocal tariff on a wide range of Pakistani goods, significantly lower than the initially proposed 29%, under a sweeping new executive order signed by President Donald Trump. Late on Thursday, President Trump signed an executive order imposing tariffs ranging from 10% to 41% on US imports from dozens of countries and foreign locations. Rates were set at 25% for India's US-bound exports, 20% for Taiwan's, 19% for Thailand's and 15% for South Korea's. He also increased duties on Canadian goods to 35% from 25% for all products not covered by the US-Mexico-Canada trade agreement, but gave Mexico a 90-day reprieve from higher tariffs to negotiate a broader trade deal. On Thursday, PSX roared back to life as bullish momentum dominated the trading floor. This sharp surge came on the heels of a surprise tweet by US President Donald Trump, who announced what he described as a historic trade deal with Pakistan. The benchmark KSE-100 Index went up by a remarkable 978 points, equivalent to a 0.71% increase, to close at 139,390.42 points. Internationally, Asian shares fell on Friday after the US slapped dozens of trading partners with steep tariffs, while investors anxiously await US jobs data that could make or break the case for a Fed rate cut next month. MSCI's broadest index of Asia-Pacific shares outside Japan fell 0.7%, bringing the total loss this week to 1.8%. South Korea's KOSPI plunged 3% while Taiwanese shares fell 0.9%. Japan's Nikkei dropped 0.4%. Chinese blue chips were flat and Hong Kong's Hang Seng index eked out a small gain of 0.2%. EUROSTOXX 50 futures slipped 0.2%. Both Nasdaq futures and S&P 500 futures eased 0.2% after earnings from Amazon failed to live up to lofty expectations, sending its shares tumbling 6.6% after hours. Meanwhile, the Pakistani rupee maintained its upward trajectory against the US dollar, appreciating 0.05% during trading in the inter-bank market on Friday. At close, the currency settled at 282.72, a gain of Re0.15. Volume on the all-share index increased to 609.71 million from 577.35 million recorded in the previous close. The value of shares rose to Rs50.55 billion from Rs36.35 billion in the previous session. WorldCall Telecom was the volume leader with 55.01 million shares, followed by Pak Petroleum with 43.04 million shares, and Oil & Gas Dev with 37.04 million shares. Shares of 483 companies were traded on Friday, of which 199 registered an increase, 246 recorded a fall, while 38 remained unchanged.

Google unveils Gemini 2.5 Deep Think, its most advanced AI model
Google has introduced Gemini 2.5 Deep Think, its most advanced AI reasoning model, capable of processing multiple ideas at once to provide the best solution. This new model runs multiple agents in parallel, using computational resources to explore various possibilities before selecting the most accurate answer. Unveiled in May 2025 at Google I/O, Gemini 2.5 Deep Think is the first publicly available multi-agent AI from the company. It recently helped Google win a gold medal at the International Math Olympiad (IMO), where its version solved complex mathematical problems. For researchers, scientists, and academics tackling hard problems: Gemini 2.5 Deep Think is here. 🤯 It doesn't just answer, it brainstorms using parallel thinking and reinforcement learning techniques. We put it into the hands of mathematicians who explored what it can do ↓ — Google DeepMind (@GoogleDeepMind) August 1, 2025 Available to Google's Ultra plan subscribers, priced at $250 per month, Gemini 2.5 Deep Think is housed in the Gemini app. Google is now sharing its IMO-winning model with a select group of academics and researchers.
