Hey r/macOS. Full disclosure: I'm a solo dev, this is my app, and I'm posting under the Saturday self-promotion rule. Been building it for the past 6 months.

**The problem** I kept re-explaining the same Mac tasks. Onboarding someone, or answering the same "how do I do this" question for what felt like the tenth time. Doing it by hand means screenshot, crop, annotate, write the step, repeat, and there goes the afternoon.

**Why I didn't just use Scribe or Tango** Both are browser extensions built for web apps, and they're fine at that. But most of what I document isn't in a browser. It's Finder, System Settings, the occasional native app. The browser tools simply can't see any of it.

**What StepGrab does** Hit record, do the task once, and you get a numbered step-by-step guide. Every click becomes a screenshot of the exact window, with the step text already written for you. Exports to GIF on the free tier, PDF and MP4 on Pro.

**The part I actually care about** Everything runs offline, and the AI that writes the step text runs on-device. There's no account or sign-up, so nothing about your screen ever leaves your Mac. It's also a native app, no Electron. A lot of what people document is internal or sensitive stuff, and I didn't want a cloud service sitting in the middle of that.

**Pricing** The free tier is actually usable: GIF export, up to 5 steps per guide, 10 guides total. Pro is $9.99/year or $49.99 lifetime (I hate forced subscriptions too) and removes the limits plus adds PDF and MP4 export. There's a 2-week Pro trial either way.

Six months of evenings and weekends went into this, so roast away. I'm especially curious what you think of the capture approach and the on-device model. Happy to get technical in the comments.

Record a Mac task once, get a step-by-step guide. I spent 6 months building this native app — 100% on-device, offline, no Electron.
