I’ve been using GPT-5 Codex to critique its own outputs with a recursive feedback loop.

With mistle.dev side threads, I run critique → reflection → revision cycles.

It actually works pretty well.

Relaunching Zapi as mistle.dev

Mistle is Cursor for non-technical builders.

We built Mistle to help non-technical builders learn, understand, and get better as they build.

We've got a few early users who jumped from Cursor to Mistle.

If you're non-technical, give Mistle a try.

We're launching Zapi as an AI Copilot for Product Teams.
With Zapi - Write and turn PRDs into prototypes in minutes.

How it works:
1. Prompt your idea.
2. Iterate till you get a working PRD
3. Zapi builds a hi-fi prototype according to your specs
4. Publish and share with your team

Before building an app, it's important to determine an initial direction and requirement.

But writing a doc is boring and time-consuming. So we built Zapi to one-shot a comprehensive product requirements document (PRD).

UX often breaks not because it was bad but because the product grew.

Zapi started with 1 view mode. As we added more, we used a dropdown.

It worked until it didn’t.

Now with 7 modes, we moved to a sidebar for clarity.

UX isn’t set and forget. Revisit what used to work.

We're looking for beta testers!

Zapi turns your ideas into a specifications doc and then follows the plan to build your idea.

As a beta tester, you get 100 free messages.

Join in 2 easy steps:
1. Join our discord: discord.com/invite/2RQ2g...
2. Post in #general channel with your Zapi user id

Tackling usability issues with navigation.

Which is more UX friendly?

Top version - collapsible sidebar menu
Bottom version - dropdown menu

Made improvements to the UX selection around agent outputs in a chat interface.

How does this look?

Through talking to users, it became clear that a chat interface doesn’t make site-building intuitive for non-technical folks.

Dev terms aren't part of a layperson's vocab. That’s why we're releasing Specifications Mode, where a PM agent translates your ideas into specs.

Just released Secrets Management in Zapi:

- Build integrations safely without exposing sensitive configurations to AI or in the codebase
- Use a separate set of secrets for preview vs live environments

A changelog is a great forcing function to stay accountable.

Each week at Zapi (heyzapi.com), we:
1️⃣ Prioritize changes that move the needle
2️⃣ Build
3️⃣ Publish updates

If we didn't make a good update or missed one - we reflect and do better.

What's your forcing function?

Love @posthog.com as a brand and product. These days, it is so rare to see truth in advertising.

Shipped a markdown editor in Zapi. No more prompting to edit content.

Seems like LLMs also suffer from the Justin Case syndrome when left to their own devices. iykyk

Wow! Super blown away by animejs docs. Using animation as nav is so intuitive and so good!

Just launched the ability to build backend capabilities in Zapi! For now, it works great with building forms and waitlists. We're going to be tuning this further over the next couple of weeks so that people can build apps.

Give it a try and let me know your feedback.

Gemini Pro 2.5 is here, and Google isn’t messing around—it beats Claude 3.7 in Aider's Polyglot benchmarks! Can't wait to test how well it works with Zapi(heyzapi.com). But first... let me ship multi-agents.

Benchmarks here: aider.chat/docs/leaderb...

AI keeps surprising me - when it works, it's like magic. I'm upgrading our single agent architecture for code-gen into a multi-agent setup. I'm only halfway but the results are already blowing me away. Here's a site that Zapi built with a design that I could have never ever done myself. Insane...
