Riffo

Riffo is a macOS desktop app that uses AI to clean up the chaos of a typical Downloads or Desktop folder. Its two headline capabilities are bulk file renaming, where it inspects each file's content and rewrites generic names like 'IMG_3421.png' into something descriptive, and auto-foldering, where it proposes a folder taxonomy and sorts everything into it. There is also a browser-based demo for users who want to try the rename pipeline before installing.

It is aimed at people drowning in screenshots, downloaded PDFs, and one-off documents who don't want to set up a Hazel-style rule engine by hand. The pitch is essentially zero-config: point it at a folder, let an LLM read filenames and content, and accept or reject the suggested renames. Riffo is free to download with no published premium tier on the marketing site, and the company says it runs on AWS, Google Cloud, and OpenAI, which implies GPT models are doing the actual content understanding.

The obvious caveats are platform scope and privacy: it's Mac-only at the moment with no Windows or Linux build, and because the AI inference appears to be cloud-hosted, sensitive documents will be sent off-device for naming. Power users who already have shell scripts or rule-based tools like Hazel may find the value thin, but for non-technical users with thousands of unsorted files it's a quick win.
