Release 2.6  ·  Codename Slipstream  ·  Shipping now

Rio AI just learned to keep up with you.

Slipstream is the biggest Rio AI update since launch. Your AI companion now follows you across every display, drafts in your voice, and proofreads as fast as you can type — while sitting so light on your Mac you'll forget it's running. Built for the teams the giants overlook. Here's everything that changed.

The headline features

Four things that make Slipstream feel different

New

It finds the screen you're on

Move to a second monitor and Rio AI moves with you. Slipstream docks the companion to the corner nearest your cursor, on the display you're actually using — no dragging, no hunting. Click once to summon it; click away and it slips back out of frame.

Improved

Grammar that keeps up with your typing

The proofreader is rebuilt on native macOS text intelligence — spelling, grammar, and clarity checks that surface inline as you write, in six languages. No round-trip to a server, no waiting on a spinner. It just underlines the fix and gets out of your way.

New

Drafts that sound like you sent them

Ask Rio AI to reply and the draft goes out under your own name — your tone, your sign-off, never a robotic "sent by an assistant" footer. You review every word before it leaves. Internal review labels stay internal; they can't ride along on a real send.

Improved

Barely there when you're not using it

We rewrote how the companion animates. Ambient motion now runs on the graphics layer instead of redrawing the window, so idle Rio AI sips power in the background. Your fans stay quiet, your battery lasts, and it wakes the instant you call it.

The full changelog

Everything in 2.6 · Slipstream

The complete list of what's new, what got better, and what we fixed. Nothing hidden.

New Added

  • Screen-follow companion. Rio AI pops on the display you're using and docks to the corner closest to your pointer.
  • One-click summon. A single click brings the companion forward from anywhere; it tucks away when you click off.
  • Multilingual proofreading. Grammar and clarity checks now cover six languages, switching automatically with your text.
  • Draft-as-you. Outbound drafts carry your name and voice, with a mandatory review step before anything sends.

Improved Refined

  • Native grammar engine. Rebuilt on the system text stack for instant inline spelling, grammar, and phrasing suggestions.
  • Idle efficiency. Ambient motion moved to hardware layers; icons are cached so the panel no longer redraws itself at rest.
  • Faster wake. The companion opens and focuses noticeably quicker when summoned mid-task.
  • Secure team access. Proofreading for staff now sits behind verified single sign-on, scoped to writing only.

Fixed Squashed

  • Stuck-position bug. Auto-hops between displays no longer leave the panel pinned to the wrong corner.
  • Review labels leaking. Internal review tags can no longer attach to a real outbound message. Fails closed, every time.
  • High CPU at rest. Eliminated the redraw loop that kept the companion busy while idle.
  • Focus flicker. Summoning Rio AI over a full-screen app no longer steals and drops focus.

The road ahead

Where Slipstream goes next.

We ship in the open, and we're just getting started. Here's the direction we're building — shared so you can see where Rio AI is headed.

More native connectors

Deeper, first-class links into the tools teams ask for most — so more of your stack lives under one command bar.

A team-wide command center

Shared agents, roles, and approvals across a whole team, with the same ask-first guardrails you set today.

Longer agent memory

Rio that remembers more of your context, your voice, and your standing preferences across sessions.

Companion beyond the Mac

We're exploring where the companion should live next. Mac stays home base; more surfaces are on the map.

Update, answered

Getting on Slipstream.

What the update takes, what it costs, and what runs it.

How do I update to Slipstream?

Open the companion, click your avatar, and choose Check for updates. Slipstream installs in the background and picks up right where you left off — about a minute, no reinstall.

Does the update cost anything?

No. Slipstream is a free update for every Rio AI seat.

Which Macs does it run on?

macOS 13 or later, on both Apple silicon and Intel Macs.

Which languages does the proofreader speak, and does it need the internet?

Grammar and clarity checks run on native macOS text intelligence, on-device, and now cover six languages — switching automatically with your text. No server round-trip, no waiting on a spinner.

Will my drafts really go out under my name?

Yes — your tone, your sign-off, and no robotic 'sent by an assistant' footer. Internal review labels stay internal and can't ride along on a real send, and you review every word before it leaves.

Are the speed and footprint numbers guaranteed?

They're illustrative of this release. Real-world speed, wake time, and battery impact vary by Mac, macOS version, workload, and configuration.
