Featuring games like:
1. Drawing characters, stroke order
2. Similar characters
3. Radical breakdowns
4. Pinyin

Built 100% with @anything, absolutely no code written by me!

“how much do u miss ur coworker?”

[Daniel Chen @naaaahman]

Interestingly, RefactorBench-JS (built while I was at @anything) showed that frontier LLMs do quite poorly at refactoring React/React-native files with no tests, with sonnet/opus series achieving no better than 23.6%. Interestingly, higher version models did not do better than earlier versions, and sometimes worse.

[Daniel Chen @naaaahman]

[Daniel Chen @naaaahman]

[Daniel Chen @naaaahman]

Introducing Skydive by Anything.

@get_mocha Good luck Mocha team!

[Mocha @get_mocha]

Mocha is winding down.

After two years, we’ve made the decision to sunset the product. We started with a bet that anyone with an idea should be able to build actual, useful, real working apps with auth, databases, backends, and one-click deploys. We believed the people locked out of building software had some of the best ideas of anyone.

And for a lot of you, it worked. Real small business owners and creators built actually useful software with Mocha: customer portals, booking systems, internal tools, side projects that turned into businesses. People who'd never written a line of code, running their work on software they built themselves. That part was real.

But the business underneath had its challenges. A combination of high user acquisition costs driven by competition, expensive unit economics due to AI token requirements of the product, and high support costs all compounded into making the business capital intensive. We weren't able to raise the capital to withstand this over the long run. Closing is the right call for our team and our investors.

The best part about our journey was you, our users. We care deeply about our users, so we spent real time finding the right home for your apps — and we found one in @anything. They share our philosophy: integrated, opinionated, built for people who describe outcomes and want working software. As a bonus, they support mobile apps, something many of you have been asking us for. Mocha apps will be in good hands there.

They've built a one-click migration that ports your apps over and keeps them live. We've tested it. It works.

They’re also going to provide dedicated help to anyone looking to migrate over.

Timeline:

Today: New signups closed. Existing customers, we're here for you.
Through July: Migration support and reminders.
August 1: Mocha's app builder shuts down. Migration and export tools stay open for 30 days after.

Move your apps → https://t.co/vHsK9S6o0q ($20 in credits to help with post-migration edits) Prefer to export and self-host? Settings → Export.
To everyone who built something with Mocha: thank you. Watching what you made was the best part of this journey. The era of idea people and personal software isn't over. It's just beginning.

I have a feeling that english is gonna lose its grammar features at this rate and will start to sound more like Chinese.

Ever since I started using LLMs more my typing has gotten worse.
