The idea of a "super app" for work with AI doesn't work for me. Different tools for different jobs: Building with cloud agents: Amp Hand-writing & editing: Flywrite Deep research projects: Codex Background tasks: Grok Bot Strategic thinking: ChatGPT & Claude

This is how we work now. Multiple projects happening. Each orchestrated by a lead agent delegating to sub agents. Each working on their own machine (orb) with @AmpCode. What a time.

I miss freely using an mdash when it's actually warranted.

So much of my multi-tasking is just preliminary research: "Here's a complicated thing that needs to happen soon. Research the complexities, consider our options, and map out what our starting point should be." Then I cycle back around and dive when I'm ready to "get into it".

Launched a refresh of buildermethods.com today (on it's 1 year birthday 🥳) It's a return to it's original promise: Helping fellow builders stay ahead as our craft is changing faster than ever.

All my work happens on orbs (cloud agents) now. I work working through one "orchestrator" who spawns a few team members (code implementer, copywriter, designer, etc.). Each on their own orb. Sometimes in different repos. Often using different models. All talking and coordinating with eachother.

Building with cloud agents is... a big deal. My next live workshop is Oct 1st where I'll show how I've moved ALL my work to the cloud. Projects, tools, multitasking, agent orchestration... All of it. Grab a seat here (free for BMP members): buildermethods.com/sessions/bui...

I'm already doing all my work from the cloud (orbin' on @ampcode.bsky.social). Working from mobile more than ever now. The idea of the iPhone Duo is getting more appealing 🤔

Brian Casel @briancasel.com · 14/09/2026
Just about every product I want to use (and build) needs: - App for UI, database, and deliverables. - MCP for agents to read and write to it. - Repo for working artifacts, agent training, & configs. - Agent skills for getting users' input.

Brian Casel @briancasel.com · 10/09/2026
I'm not a first-gen guy. But I'm surprised how appealing the Duo seems to me. I like how small it seems folded. Like the idea of more space when working from mobile. Moving the dock to the sidebar feels right. Still. Not a 1st-gen guy.

This year I’m removing templates, scaffolds, and libraries from my process. I'm realizing they're no longer shortcuts. They're constraints. AI models are improving so quickly that forcing them into old patterns means missing out on much of what newer models can help us do.

fyi - X is a lot better now. You should go back.

How I trust code I never read: 1. Heavy up-front planning sessions, PRD, specs 2. Agent self-verification loops before delivery 3. Manual QA on critical paths only No surprises. No hallucinations. A few refinements, then ready.

Today I launched 'Become AI-Native', my new training inside Builder Methods Pro. 🚀 It's a build-along style program where we redesign our processes with AI. Build custom agent skills, automations, and AI training systems, using my favorite patterns and process designs.

New in flywrite.app: I added Cursor CLI integration so it knows your current file and selection (just like it does Claude Code and Codex CLI). Now I can use my favorite markdown editor (Flywrite) with my Cursor/Grok subscription.

Brian Casel @briancasel.com · 10/08/2026
Using skills and claude.md/agents.md continues to be the most annoying "lock-in" thing. Claude more to blame here for not embracing 'agents' standard naming. Plenty of hacks and workaround strategies, of course. All annoying (and even harder to teach newcomers). 🙄

Brian Casel @briancasel.com · 10/08/2026
Working on my next course, Become AI-Native (for those new to AI-assisted workflows). Hardest part to teach: Harnesses and that rapidly changing landscape. Trying to make it practical & future-proof. ChatGPT (most popular brand name) not making it easier with their inept naming and product UX.

Brian Casel @briancasel.com · 07/08/2026
Writing and building my next course, 'Become AI-Native'. flywrite.app is the perfect tool for this type of work (writing-heavy project with some design work). Developing & iterating with Claude, hand-editing some parts...

Brian Casel @briancasel.com · 07/08/2026
Last year I created Agent OS to keep coding agents on the rails. This year, I stopped using it. Today's models do worse when you micromanage how they write code. They do better when you pour everything into planning and verification.

Brian Casel @briancasel.com · 06/08/2026
As much as I build and ship lots of stuff (public products and many internal tools)... The big trend for me has actually been stripping back and simplifying a lot. Agents and speed of iteration means a lot of heavy-handed tooling & process can fall away.

I've been extremely anti-meeting my whole career. My teams and I always worked 99% async. Now most of my day is in meetings planning big projects. I'm the only human at these meetings. Work output? Unprecedented on all metrics. No question. Enjoyment and flow? Open question.

The thing that disqualified non-technical founders (can't code) has been neutralized. What you have (deep knowledge of a real problem) can't be shortcut or replaced by AI. You're not behind. You're way ahead.

I built it. This is mimeohq.com Email marketing you own. Your list. Your flows. Your emails. Just plug in a sender (Resend, Postmark, or SES). Manage it all in the UI or with agents. Opening soon. See demo video 👇

There are obviously a ton of amazing tools that have helped us build Eventually, but I want to call out one especially: @briancasel.com Builder Methods. The community, the videos, the workshops, but especially the tools that Brian shares have all been extremely crucial for us.

Sales slowed down for a little while there. Then I remembered I hadn't updated my email sequences and automations in a while. Turns out customers still read emails.

First time in a while I'm optimistic about starting software products again. Seeing a new shape emerge: Familiar problems and tool categories solved in a way that gets accelerated by AI adoption instead of eaten by it. Requires rethinking product shape and biz model. Marketing still hard though.

Domain purchased. Gonna build the thing I've talked myself out of building for 15+ years.

If you feel like you have to review every line of code AI writes, the bottleneck isn't AI. It's micromanagement. Move that energy into planning and verification. Own the what and the proof. Let the agent own the how. That's what unlocks bigger builds.

Unpopular opinion: A domain expert who can't code is MORE qualified to build tools for their field than a pro developer is. If you know your problem space better than most, you're way ahead. Building is learnable.

"It's too expensive to build my own tool for that."...No longer applies. The busywork you assumed as just part of the job could be a weekend build (think of what could you replace that busywork with?)

In flywrite.app, your AI agents are one keystroke away. Launchers open a new terminal with something already running: a plain shell, Claude Code, or Codex — each on its own shortcut. Add launchers for your own commands, and remap any keyboard shortcut in settings.

I've been asked a lot about my video editing process now that it's handled 100% using Claude Code. It reduced the time it takes me to edit & publish a YouTube video from 7 days to 1. Here it is in detail. www.youtube.com/watch?v=GlvH...

Bootstrapped SaaS in particular should lean into (and show) their team's AI adoption as another reason why it's worth buying from them (vs "the big guys"). It signals: We ship/iterate faster. Our product is agent-ready. We're here to stay. Can't say the same about most bigs.

Your writing app should look like yours. In flywrite.app you can pick any font installed on your Mac with a live preview as you choose. Build full custom themes, down to every color, font size, and weight.

New in flywrite.app: click any image, video, or audio file in your project and it opens right in the editor — zoom images, scrub video, play audio. And it refreshes live so you can watch your agent generate visuals in real time.

Good thing I've started moving all my writing and artifact'ing into local markdown files with Claude Code and flywrite.app.
