Sider Omni is a macOS sidebar assistant that docks directly to active application windows to read on-screen context, draft text, and process tasks across documents, email, and browsers without app switching.
What the product does and how it is positioned
Sider Omni functions as an on-screen AI assistant for macOS 15 and later, attaching directly to the border of active app windows such as web browsers, document editors, email clients, and PDF viewers.
The software follows window movements and side-by-side fullscreen views, running dedicated instances per window with local conversation storage and selectable artificial intelligence models.
Source-supported ways to use the product
Extracting key deadlines, figures, and summaries from articles, contracts, and research papers directly inside PDF viewers or web browsers.
Identifying action items, assignees, and next steps from meeting notes inside note-taking applications.
Summarizing long message threads, searching messages, and drafting replies directly within desktop email clients.
Transforming text outlines into presentation slides, tightening slide copy, and generating speaker notes inside presentation software.
The documented workflow, where available
Download Sider Omni for macOS, finish the installation, and sign in to an account.
Grant the necessary macOS permissions and pick an assistant avatar.
Select any application window, click the avatar in the upper-right corner to display the sidebar, and initiate tasks in plain language.
Sider Omni attaches directly to individual application windows rather than operating as a standalone desktop floating window. As users drag, resize, or shift into fullscreen view, the sidebar maintains its alignment alongside the selected software interface. This architectural design enables users to keep focus directly within active workflows across word processors, spreadsheets, and web browsers.
The tool supports independent Omni sessions for separate windows, allowing distinct conversation contexts to exist simultaneously without interference. Users can also issue commands that span across windows or trigger parallel processing tasks when multi-application workflows are required.
