Phi 2.1.0

Phi Browser 2.1 is here, and this one is mostly about making Spaces feel more complete, less mysterious, and less like something you need to spiritually negotiate with.

Private Spaces are now supported, so you can keep certain browsing sessions properly separated, including opening supported links directly in a private window. Spaces are also easier to manage now, with a new Close Space action, clearer icon choices when creating a new Space, and better behavior around bookmarks, folders, pinned tabs, and profile imports.

We also spent some quality time with the sidebar, because apparently even sidebars deserve personal growth. The macOS UI now behaves better, especially when the sidebar is floating, and there are clearer entry points for Sentinel and experimental local AI features in Settings. You can also open the AI sidebar directly from the Help page, because help should ideally help. Revolutionary concept.

AI tab tidy-up is faster with larger tab sets, and less noisy too. It now shows up only when it might actually be useful, rather than standing around like an overconfident intern. We also fixed several AI chat issues around attachments, PDFs, images, response formatting, and changing your assistant’s name and avatar from inside a conversation.

A few everyday paper cuts are gone as well: copying the current page URL is quicker with a new shortcut, pasted URLs with trailing line breaks behave properly in the new tab search box, picture-in-picture works more reliably when switching Spaces, and “Ask Phi about” now plays more nicely with Sidecar and split view.

Finally, we improved Gmail and live data reliability, cleaned up onboarding and conversation UI inconsistencies, strengthened app stability and crash diagnostics, and made a few security and backend improvements in the background. The usual unglamorous plumbing, without which the beautiful sink becomes a public incident.
