Tidy

There's a quiet revolution happening in the AI productivity space, and Tidy is waving the flag. For years, grammar tools like Grammarly have owned the conversation, but they've always come with baggage: cloud processing, subscription paywalls, and the nagging feeling that your private drafts are being fed into someone else's model. Tidy flips that script with on-device AI that works across any Mac app. That's not just a feature—it's a philosophy shift. In a world where every startup is racing to bolt AI onto everything, the ones that prioritize *privacy* and *speed* are the ones that win the trust of power users. The "any Mac app" angle is what really gets me excited. Founders live in a patchwork of tools—Slack, Notion, Mail, Figma comments, Linear, you name it. Most grammar tools force you to leave your flow state and paste text into a separate window. Tidy removes that friction entirely. If it works as seamlessly as described, it's the kind of invisible utility that becomes indispensable within days. That's the dream for any SaaS product: not a destination, but a layer under everything you already do. And let's talk about the "free" part, because that's a bold move. On-device AI has a real cost advantage—no servers to spin up, no API bills to pay—so Tidy can afford to give the core experience away. This is the emerging playbook for local-first AI: use the hardware the user already owns, and let the software be the moat. It's a direct challenge to the cloud-based incumbents who've built their entire pricing model around per-seat subscriptions. If Tidy executes well, it could force a race to the bottom on price and a race to the top on privacy. The bigger story here is the broader shift toward edge AI. Apple has been pushing on-device intelligence for years, and tools like Tidy are proving that the approach isn't just viable—it's *preferable* for certain use cases. Grammar correction is a perfect fit: it's low-latency, privacy-sensitive, and doesn't require a massive model to do well. As more developers realize that, we're going to see a wave of local-first apps that challenge the cloud-centric status quo. Tidy is at the front of that wave, and it's worth watching.
