Hey AI Enthusiast,

I hope you’re doing well wherever you are.

This episode is special: I demo how to build a fully functional app using only your smartphone—no coding experience required.

Later, we briefly reflect on Anthropic’s Series E funding and an intriguing new smart-glasses app.

Replit AI Agent on the Smartphone

I waited a bit before trying it out, but now I’ve finally done it: the Replit AI agent for mobile (available in their Replit app) is fantastic. With simple natural language, you can generate fully functional apps.

You can even iteratively improve the app directly on your phone and deploy it with just one click.

The main content outlines an MVP (Minimum Viable Product) plan for a “Digital Time Capsule Service.” It explains that individuals can create digital time capsules with letters, messages, or reflections (potentially including images, videos, and other data) intended to be opened in the future (up to 100 years). It emphasizes that the service appeals to users interested in legacy and secure storage. Another bullet point notes the service involves a one-time payment, limiting recurring revenue but possibly attracting popularity if marketed well. The agent responds positively, proposing details for building the described MVP. The interface includes options for interactive capsule features and capsule sharing.

Watch the demo below to see how I built a time capsule service—honestly, it’s pretty genius, so hands off!

I’m planning to launch it soon! Haha.

Here’s the Replit link.

Once you’re done being amazed at how ridiculously easy this is, grab the codebase, toss it into Cursor AI, and tweak it until your inner perfectionist chills the hell out.

The usual spiel as described in earlier episodes.

Anthropic raises Series E at $61.5B post-money valuation

Overlaid are stylized, curved black lines that smoothly jump from step to step, symbolizing iterative progress or incremental improvement. The illustration conveys the idea of progressing step-by-step, possibly indicating iterative design or development.

First, Anthropic releases Claude 3.7 Sonnet, which makes waves not only in the developer community, then immediately raises serious cash. That’s how it’s done.

Anthropic secured $3.5 billion, reaching a valuation of $61.5 billion—huge, but still nowhere near OpenAI’s $157 billion.
