This issue rounds up five stories: Google's real-time AI music instrument, a viral Obsidian-plus-Claude-Code automation pipeline, OpenAI's reported plan to merge ChatGPT, Codex, and a browser into one platform, South Korea's “dopamine website” trend, and Manus's new Shopify connector.

Google built a real-time AI music instrument you play like a synth

Google released Magenta RealTime 2, an open model that musicians can treat like a live instrument. It accepts MIDI input, text prompts, and audio, then responds in real time with low-latency synthesis running natively on Apple Silicon—no cloud, no render wait. The demo shows expressive generation that feels like jamming with a bandmate who never misses a cue.

This builder's Obsidian setup ships entire projects while he sleeps

A builder went viral showing an Obsidian setup working as a full automated pipeline. He drops a raw idea note at 3am; automation classifies it as a project, grocery list, or something else. If it's a project, agents auto-research it, check existing tools, and write a proposed plan. The one human step: open Claude Code, review the plan in a couple of minutes, then approve it. Sub-agents then build the whole thing while he sleeps.

OpenAI is reportedly merging ChatGPT, Codex, and a browser into one platform

According to reporting from the Wall Street Journal and other outlets, OpenAI is preparing to merge ChatGPT, its Codex coding agent, and browser functionality into a single desktop platform, overseen by Chief of Applications Fidji Simo alongside President Greg Brockman. The stated goal is to reduce fragmentation across OpenAI's separate products and create one consolidated interface for chat, code, and browsing.

South Koreans are using fake delivery apps to scratch the shopping itch without spending anything

South Korea's “dopamine websites” trend has people using fake food delivery menus to browse, fill carts, and watch a fake courier move across a map, all without actually ordering. Virtual smoke-break chatrooms simulate the social ritual of stepping outside without the cigarette. The explicit goal is getting the dopamine hit without the cost or the habit; reactions online have called it both “genius harm reduction” and “dystopian brainrot.”

Manus's Shopify connector builds a full store from one chat

Manus launched a Shopify connector that lets you build and manage an entire Shopify store through a single chat. Tell it your product, your audience, your vibe, and it generates copy, images, collections, product catalogs, and marketing campaigns, then handles storefront building and ongoing management. It works for new founders starting from zero and existing Shopify merchants who want to scale content without adding headcount. A paid Manus plan is required.
