Keep the web within reach.

Side Whisper is a compact desktop sidecar for the web apps, chats, guides, dashboards, and words you need close. It stays aligned, moves deliberately, and gets out of the way when your attention belongs somewhere else.

THE PRODUCT THESIS

Alt-Tab is not a workflow. Your desktop should remember context.

Traditional browsers optimize for destinations. Side Whisper optimizes for proximity: the small set of web tools that should remain attached to what you are already doing.

SIX CONNECTED SYSTEMS

Not a widget. A complete sidecar for Windows.

A sidebar that behaves like a place

Pin the web apps and links that matter to either screen edge, group them with dividers, and move the whole setup across monitors without rebuilding it.Drag ordering, unread badges, custom icons, named templates, left or right placement, and a compact 48 or 100 pixel rail.

A browser built for the side of your work

Every saved item opens in its own aligned browser window with tabs, search, bookmarks, downloads, find, permissions, and per-site privacy controls.The browser stays focused on quick companion tasks instead of trying to replace every long-form browsing session.

Gaming modes with an explicit input contract

Choose View, Interact, or Focus. Read through a click-through overlay, use visible controls, or deliberately take keyboard focus when you need to type.Opacity controls, fullscreen-aware windowing, multi-monitor placement, quick search, and optional real local performance telemetry.

Offline dictation, not a cloud microphone

Run Whisper locally, trigger recording from a global shortcut, correct personal vocabulary, expand snippets, and paste into the app you are already using.Tiny, Small, Large Turbo, and Large models are downloaded only when you choose them.

Privacy controls you can inspect

Block ads and trackers per domain, review real blocked counts, manage enforceable site permissions, and keep browsing and voice data on your device.Side Whisper does not pretend unsupported controls exist and does not fabricate privacy or performance claims.

A command layer for repeated setups

Use the Operator Console to search commands, jump to open tabs, and switch complete sidebar workspaces with keyboard-first flows.Built-in and personal templates support replace, merge, import, export, shortcuts, and undo.

GAMING, WITHOUT THE FOCUS FIGHT

The overlay tells you who owns the input.

Side Whisper separates passive visibility from pointer interaction and real keyboard focus. That distinction matters when a guide, chat, login popup, or payment window sits above a fullscreen game.

View

Keep the page visible while pointer input continues to the game.

Interact

Operate the overlay controls without promoting a full desktop browser workflow.

Focus

Deliberately transfer keyboard ownership for typing, sign-in, and navigation.

LOCAL MEANS LOCAL

Speak into the app you are already using.

Choose a Whisper model, record from a global shortcut, correct names and acronyms, expand local snippets, and paste the result without sending your microphone recording to Side Whisper.

Explore offline voice

TRUST IS A PRODUCT SURFACE

Privacy claims should be inspectable.

Side Whisper keeps browsing state, website sessions, saved links, permission choices, voice data, and performance telemetry on the device. The account service receives only the identity, consent, entitlement, device, session, and release metadata needed to provide access.

Per-domain ad and tracker blocking with real local counts
Supported permissions only, unknown capabilities fail closed
No uploaded browser history, transcripts, or game telemetry
No fabricated FPS, GPU, temperature, or privacy values
Privacy-safe diagnostics export excludes URLs, titles, emails, and tokens

WHERE IT FITS

One product, several kinds of attention.

Side Whisper is useful when context is persistent but not primary: the thing you need beside the task, not on top of it.

Keep guides and chat above the game

Read passively, interact with visible controls, or take focus only when you need to type.

“Premium” should mean fewer surprises, clearer boundaries, and a product that feels attached to the work.
