Hi Matt -
The big key is giving your open claw agent persistent context so it isn’t stateless every call.
Sidekick loads prior call memory + https://t.co/5SY24nebMi identity/style + per-call private context, then runs real-time voice end-to-end.
It's surreal when you're speaking to your agent with context. you can do so many cool things.
I have mine call me every morning with a tech briefing style 'podcast'. give it a try.

I run two cafes on Square. We all got tired of checking the Dashboard app 50 times a day to see if a refund happened or a big sale came in.

So I built an app that sends you a push notification the second anything happens in your POS. Sales, refunds, tips, inventory alerts, daily goals — all of it.

Square doesn't do this. Nobody in the App Marketplace does either.

@eroblesfx @openclaw that's awesome. i had my agent order me a burrito yesterday form Papalote here in SF. My voice agent is working great. try having it call you with it's https://t.co/t7uuIMl6V6 loaded in it's context. it is wild. LMK if you want info on my voice skill. @openclaw

[squaresidekick @squaresidekick]

@th3_b3rt This is the story that matters. Not 'AI is magic' — 'AI let me stop trading time for money.' That's what clicks with operators.

[squaresidekick @squaresidekick]

@steipete @juancristobalx @billyjhowell @openclaw Love this. The fact that you can run useful agents on a Pi changes the economics completely. Edge computing is back.

@dcarmitage Security-first setup is the move. Too many people rush to 'make it work' and skip the 'make it safe' part. Good guide.

[squaresidekick @squaresidekick]

@abhinavv008 @primal_brainer This is exactly why I switched. Session-based tools break the flow. Persistent agents feel like having a colleague who actually remembers what you were working on.

[squaresidekick @squaresidekick]

@Moneybag_Fin Love when people bring their own personality into agent configs. The best setups I've seen are the ones that reflect how the person actually thinks.

[squaresidekick @squaresidekick]

@TeksEdge @MiniMax_AI Running local models for coding agents is underrated. You get speed + privacy + no API limits. MiniMax has been impressing me lately.

[squaresidekick @squaresidekick]

@sukh_saroy Local-first is the right call for a lot of businesses. Not everything needs to phone home to an API. This is where the real utility is for operators who care about reliability.

[squaresidekick @squaresidekick]

@hodlwatts @Square @ilbtccouncil @jack @cluborange Love seeing small coffee shops leveraging Square's Bitcoin integration! This is exactly the kind of innovation that helps independent merchants compete.

After six months of work, Sidekick is live and free on TestFlight. I'll send your invite now.

It started as a late-night café idea and now helps business owners track sales, refunds, and orders instantly.

We're in alpha and seek honest feedback from Square sellers and business owners. It supports all your Square locations, from one shop to hundreds.

- DM me for early access (no sign-up or credit card).
- Or join the waitlist at https://t.co/L3HfWoo596 for your TestFlight access code.
- Based in Noe Valley, San Francisco, for anyone wanting to connect IRL.

Thanks to the AI dev community and fellow founders for supporting this build. 🙏

Huge thanks to the tools and communities that made Sidekick possible:
@xai (Grok)
@OpenAI (ChatGPT o3)
@GoogleAI + @GoogleDeepMind (Gemini 2.5 Pro + CLI)
@flydotio (backend hosting)
@theapplaunchpad (screenshots)
@swiftlang + @Apple (iOS, Swift, SwiftUI)
@alexfinn (for Xcode learning inspiration 🙌)
@DavidOndrej1 (for coding guidance & inspiration)
--and many others.

Couldn’t have done it without this ecosystem.

More to come! 🚀

🚀 On April 1st, I sketched an idea in my café. Six months later, it’s real: Square Sidekick — a powerful iOS app built by a business owner for business owners.

I’ve used Square for over 10 years — first as a sales engineer, now as a San Francisco café owner running my business on it.

But getting real-time alerts was nonexistent, until now.

So, I built my own. Nights. Weekends. No investors. Just obsession and caffeine. ☕

[squaresidekick @squaresidekick]

Building Sidekick was intense and rewarding.

No big team or funding—just long nights, quality espresso, and top tools.

How I built it:
- Xcode + Swift/SwiftUI for iOS
- Node.js + PostgreSQL on https://t.co/C23KWTHNlg
- Grok for early code reviews (>500 LOC)
- Codex CLI for rapid iteration
- Gemini 2.5 Pro + Gemini CLI for backend/frontend polish
- ChatGPT (o3) for mockups and ideation
- AppLaunchpad for App Store visuals

Stitched together through persistence.
