The full desktop client rather than a browser shortcut, with the companion window, screenshot capture, file reading, and voice mode all present in the package and every paid tier feature left switched on from the first launch.

Version 2026.709.1617.0 684 MB Windows 10 / 11 (64-bit) Updated 4 days ago

Overview

What this release is

The desktop build is a very different tool from the web page most people know. It sits on a global hotkey, opens a small companion window over whatever you are already doing, and reads the active window so you can ask about a spreadsheet, a stack trace, or a page of documentation without copying anything into a browser tab. Once that habit forms it is difficult to go back to alt tabbing.

File handling is the part that gets used hardest in practice. Drop in a folder of documents and the client indexes them locally, then answers with references back to the specific file and section it drew from. Spreadsheets are parsed as data rather than as text, so column questions get arithmetic answers instead of confident guesswork, and long PDFs keep their structure well enough that page references stay accurate.

Voice mode runs in a separate lightweight window that stays responsive while the main application is busy. Interruptions are handled properly, so talking over a reply cuts it off the way a phone call would rather than queueing a second answer behind the first. The transcript is written into the same conversation history as typed messages.

This release is the complete signed application with the companion overlay, the screenshot pipeline, the local file index, and the voice stack included. The tier gate has been removed, so the model picker, longer context handling, and the advanced reasoning options are all selectable rather than greyed out behind an upgrade prompt.

Feature set

What you get

Companion window

A global hotkey brings up a compact prompt over any application, with the active window available as context without a manual copy and paste step.

Screenshot context

Capture a region of the screen and ask about it directly. Charts, error dialogs, and design mockups are read in place.

Local file index

Point the client at folders and it builds a searchable index on the machine, answering with citations back to the source file and section.

Voice mode

Low latency spoken conversation in its own window, with proper interruption handling and transcripts written into the normal history.

Model picker

Every model tier is selectable from the composer, including the longer context and deeper reasoning options normally reserved for paid plans.

Projects

Group conversations, files, and standing instructions into a project so context carries between sessions instead of being pasted in each time.

Changes in this build

What changed

Companion window rebuilt with lower memory use and faster cold open
Local file index now handles spreadsheets as structured data rather than flat text
Voice mode interruption latency cut by roughly half
Projects gained per project standing instructions and pinned files
Fixed the hotkey conflict that broke the overlay on some gaming keyboard drivers

Installation

How to install it

Turn off real time protection before extracting. The setup routine rewrites its own manifest and that trips heuristic scanners.
Extract the archive to a short path such as C:\Setup so the nested resource folders do not exceed the path limit.
Run the installer as administrator and let it finish before opening the application.
On first launch skip the account prompt entirely. The client opens straight into the composer.
If you want the tier state to hold, block outbound access for the updater helper while leaving the main executable alone.

Questions

Before you start

Does the application work without a connection?

The interface, history, and local file index open offline, but replies come from the service so a connection is needed to actually ask anything.

Is the local file index sent anywhere?

The index itself is built and stored on the machine. Only the excerpts relevant to a question travel with the request.

Why does the client update itself?

The bundled updater checks on a schedule. Blocking that helper keeps the build exactly where it is.

Can it replace the browser version entirely?

For most day to day use yes. A few account management screens still open a browser window when clicked.
