As answered by people managing Trailback and Diffee.
Trailback's answer
Rewind has stopped recording, and Microsoft Recall only runs on Copilot+ PCs. Trailback works on any Mac (macOS 13+) or Windows 10/11 PC, fully offline, for a one-time price instead of a subscription.
Beyond search, you also get Quick Search from any app (with drag and drop), a timeline to go back and reopen past work, automatic Collections, Tidy for messy file names, and offline PDF and image tools.
Trailback's answer
Trailback remembers what you did on your computer: websites you visit, files you open, screenshots you take and text you copy. You find any of it by describing it in your own words, like "the invoice from last month".
It does all of this 100% offline. Nothing is uploaded, there's no account, and your data is stored encrypted on your own computer. And it works on both Mac and Windows.
Trailback's answer
Founders, freelancers, knowledge workers, students and researchers. Anyone who works across lots of files, browser tabs and screenshots and keeps losing things they know they've seen.
It's also for people who care about privacy and don't want an app uploading their activity to the cloud.
Trailback's answer
I'm Pavan, a solo founder from Hyderabad. I kept losing things I knew I'd seen: a PDF from last week, a page I read, a screenshot with a number in it. I never remember file names. I remember what the thing was about.
The tools that solved this either sent my data to the cloud or only worked on certain hardware. So I built Trailback: a memory for your computer that stays on your computer.
