Sound familiar?

Once the main task is fullscreen, every lookup becomes a switch

Writing docs, working on spreadsheets, taking meeting notes, or studying all have the same problem: the moment you need a webpage, you leave the task, find the browser, then find your way back.

Your everyday web tools are buried in browser tabs

Search, translation, knowledge bases, email, calendars, AI, and internal tools all end up in one overloaded browser. When you need something quickly, you're hunting through tabs first.

Reference pages need to stay nearby, but not in a permanent window

Course material and notes, spreadsheets and admin tools, meeting agendas and action items, papers and translation tools often need to be compared side by side, but they don't deserve your entire main screen.

Overlay doesn't replace your browser. It turns web apps, AI, docs, dashboards, and local files into a summonable workspace beside the task you're already doing.

One shortcut. Always there.

No matter what app you're in — fullscreen or not — press the shortcut and Overlay appears above it instantly. Press again, it's gone. You never actually left your work.

Default shortcut ⌥ Space, fully customizable

Floats above fullscreen apps, Mission Control, and all Spaces

Multi-display support: appears on whichever screen your mouse is on

Built for the fullscreen era

Float above everything

Keep references and web tools close without leaving the app you're in. Overlay sits above fullscreen apps, desktops, and displays so it is ready when you need it and gone when you do not.

Floats above fullscreen apps

Bring web references above docs, design tools, IDEs, spreadsheets, or any other fullscreen app without breaking your flow.

Cross-desktop spaces

Switch freely between all macOS Spaces and fullscreen apps.

Multi-display support

Automatically appears on the display where your mouse cursor is.

Edge dock

Park the window to the screen edge and slide it out on mouse hover.

Three auto-hide modes

Hide on focus loss, hide on mouse-out, or control it manually.

Custom shortcuts

Customize both global and in-app keyboard shortcuts.

Not just a tab. A full workspace.

Create multiple tabs, group related pages, then drag any tab onto the top, bottom, left, or right edge of any pane. Panes nest freely, so you can build a full-height column beside two stacked rows, a 2×2 grid, or whatever the task actually needs. The proportions you set come back the next time you open Overlay.

Drag to reorder tabs, collapse and expand tab groups

Dock a tab to any edge of any pane to build arbitrary nested layouts

Drag any divider to resize; your layout and proportions are restored on launch

Downloads are managed inside the panel, with progress and history at hand

View local PDFs, images, and videos

Organize web work around the task

Not a temporary popup, a workspace you can keep using

Search, references, AI, internal tools, and local files can be grouped, arranged into any layout you like, and used around the task.

Tab group management

Group related pages together, collapse and expand them as needed.

Any nested layout

Drop a tab against the top, bottom, left, or right edge of any pane. Panes nest freely, so any grid is possible.

Local file viewer

Open PDFs, images, and videos in the same workspace alongside your web apps.

Web alerts become Mac notifications

Web alerts show up like normal Mac notifications, and one click takes you back to the right tab.

Multi-account sign-in

Use isolated sessions to stay signed into different accounts on the same site.

Tabs and groups stay organized

Drag tabs into order and keep related web apps together in groups.

As handy as your browser

Web extensions and saved passwords

Ad blockers, translators and AI assistants keep working in Overlay's web pages, and the passwords you save fill in with one click when you sign in. No trip back to the browser for either.

Web extensions

Run Safari extensions in every web tab. The direct download can also use the extensions you've already installed in Chrome, Edge and other browsers.

Overlay finds the extensions you already have. Turn them on one by one in Settings ▸ Extensions.
Each extension lists the permissions it needs first, and nothing runs until you confirm.
The list flags up front which features won't work, which extensions use more memory, and which shortcuts clash with Overlay's.
Pop-ups, context menu items, shortcuts and side panels all work. Pin the ones you use most to the side rail for one-click access.

Extensions from

SafariChromeEdgeBraveArcVivaldi

Requires macOS 15.4 or later. Extensions from Chrome, Edge, Brave, Arc and Vivaldi are available in the direct download only; the Mac App Store version supports Safari extensions.

Saved passwords

When you sign in to a website, Overlay offers to save the password. Next time, click the sign-in field and pick an account from the drop-down. Nothing is filled until you choose.

Encrypted and stored only on this Mac, with the key in your macOS login keychain. Never uploaded, and we have no way to read them.
Showing or copying a password asks for Touch ID or your login password, and filling can ask too. Copied passwords clear from the clipboard after 60 seconds.
Works with multi-step sign-ins (Google, Microsoft), sign-in forms embedded in other pages, and pop-up sign-in windows.
Warns you before saving on plain http pages, and never offers a password saved on an https site to an http page.

Saving and autofill can be turned on or off separately in Settings ▸ Passwords.

Web notifications go native. Multiple accounts, no conflict.

Web alerts no longer disappear inside the browser. Overlay turns them into native macOS notifications, so you can see them anywhere and jump back to the right page with one click. When needed, isolated sessions also let the same site stay logged into multiple accounts.

Web notifications → macOS Notification Center, click to jump to the source tab

Per-tab notification control for each site

Isolated sessions: log into multiple accounts on the same site simultaneously

Per-tab audio mute control

Stay focused, organized, and private

Focus and control

Notifications, account separation, and per-tab controls keep useful pages close without letting the browser take over your desk.

Native notification integration

Web alerts show up like normal Mac notifications, and one click takes you back to the right page.

Session isolation

Log into multiple accounts on the same site in parallel, without interference.

Per-tab proxy control

Set a global proxy or configure a separate network exit for individual tabs.

Audio control

Mute or unmute audio independently for each tab.

Independent web engine

Each tab runs its own isolated instance without affecting others.

System tray presence

Always running in the background, with quick actions from the menu bar tray.

Overlay clicks fastest in these situations

If your day often looks like this, it will feel much better than opening yet another browser window.

Write while keeping web references in reach

Pull in sources, search results, translation tools, and AI without giving up the document you are working on.

Study or follow tutorials with notes beside them

Course pages, guides, search, and notes can stay side by side instead of competing for the same screen space.

Open agendas, docs, tasks, and AI summaries during meetings

Keep taking notes while the right web page appears when needed and disappears when it is done.

Work in spreadsheets or admin systems with instructions nearby

Compare a reference page and a live system at a glance instead of constantly bouncing between tabs.

Review papers, policies, or industry research with search and notes around them

Research work becomes one focused setup instead of a browser full of scattered tabs.

Overlay fits this kind of work

Not just for developers. If you often keep a main task open while looking things up on the web, the value is immediate.

Reports, proposals, papers, and drafts with references close by

Research and writing

Search results, articles, translation tools, and AI can be called up with one shortcut instead of repeatedly sending you back to the browser. Writing and looking things up finally stay in the same rhythm.

Agendas, messages, and internal tools without breaking the main document

Meetings, coordination, and communication

Agendas, email, calendars, tasks, chat, and internal tools can float next to what you're already doing. Keep writing notes, updating docs, or filling in spreadsheets without hunting for windows.

Email · Calendar · Slack · Feishu · Notion · Internal tools

Tutorials, SOPs, course material, and the real task side by side

Follow-along execution

Compare instructions, policies, course material, or reference pages while working in the main app. Pull them in when needed, hide them when not, and keep the main screen for the actual task.

Tutorials · SOPs · Course material · Policy docs · Translation tools

Developers, designers, operators, and analysts with lots of web context

High-frequency professional work

If your day already depends on docs, AI, specs, dashboards, tickets, or internal systems, Overlay pulls those web tasks into one helper layer so you switch less and stay focused longer.

Why not just use a browser sidebar or split screen?

Every alternative still lives inside a browser or locks you into a split. Overlay is a separate layer.

	Browser window	macOS split
Floats above fullscreen apps
Visible across all desktops	Partial
Global one-key summon
Tabs with groups
Arbitrary nested pane layouts
Session isolation (multi-account)	Needs extra windows
Not tied to one browser	—	—
Local PDFs, images, and videos	Partial

Common questions

The key things to confirm before you download.

Can I try it before buying, and what do I get after purchase?

Overlay includes a 30-day full-feature trial, so you can use it in your real workflow before deciding to buy. After payment, you receive an activation code for the macOS app.

How many devices does one activation code support, what if I switch devices, and where does the code arrive?

One Overlay activation code activates 2 devices at the same time. If you switch devices, deactivate Overlay on the old one first and then activate the new one; if the old device is no longer accessible, contact support. After payment, the activation code is automatically sent to your checkout email, usually alongside the receipt.

How is this different from a browser sidebar or a normal browser window?

Overlay is a standalone native app, not something attached to Chrome or Safari, and it can float above fullscreen apps, multiple desktops, and multi-display workflows. A normal browser window or sidebar still lives inside the browser, while Overlay appears with a global shortcut directly on top of your current task to cut context switching cost.

Is Overlay like iPad Split View or Slide Over on Mac?

Overlay is not the iPadOS Split View or Slide Over feature, but it solves a similar problem on macOS: keeping references, AI, and web tools next to your main task so you can compare content and switch less while staying in fullscreen work. It also goes past a fixed two-pane split: you can dock a tab to any edge of any pane, so the layout can be as simple as one pane or as involved as a full-height column beside a 2×2 grid.

What kind of web work is it best for?

Overlay fits high-frequency web tasks: research tabs, writing references, meeting docs, study material, AI, admin tools, design references, and tickets, especially in fullscreen workflows.

Can Overlay open local files?

Overlay can view local PDFs, images, and videos, so you can keep them in the same workspace as your web apps for side-by-side reference.

Can I use my browser extensions in Overlay?

Yes. Overlay runs Safari extensions, and the direct download can also use the extensions you've installed in Chrome, Edge, Brave, Arc or Vivaldi. Overlay finds them automatically, and you turn each one on in Settings ▸ Extensions ▸ Manage… after reviewing its permissions. Most popular extensions, such as ad blockers, translators, AI assistants and clippers, work as is, and features that won't work in Overlay are flagged up front. Web extensions require macOS 15.4 or later. Extension data in Overlay is kept separate from your browser, so extensions with an account ask you to sign in once here.

Where are saved passwords stored, and are they safe?

Saved passwords are encrypted and stored only on your Mac, with the encryption key in your macOS login keychain. Overlay never uploads them or syncs them to other devices, and we have no way to read them. Showing or copying a password asks for Touch ID or your login password, and filling can ask too; copied passwords clear from the clipboard after 60 seconds. You can import existing passwords from a Chrome, Edge, Safari, Firefox, Bitwarden or 1Password CSV export. Export is deliberately not offered.
