Frostle Ctrl ⇧ B
The difference

Built for the
moment things move

A normal screenshot tool grabs the live screen — so by the time you drag, the video has moved on and the popup is gone. Frostle freezes the entire frame the instant you press the hotkey. The world stops; you take your time.

  • True freeze-frame

    Catch a paused-feeling moment from any video, game, call, or fast chat. Nothing scrolls away while you select.

  • Answer in one gesture

    Hotkey → drag → answer. The reply streams in instantly, right where you are — no tab-switching, no uploading.

  • Yours, kept local

    History lives on your machine. Bring your own API keys and they're stored in the Windows Credential Manager — never in a file.

FAQ

Good questions

What makes “freeze-frame” different from a normal screenshot tool?

Most tools capture the live screen while you drag — so moving video, animations, or popups that disappear are gone before you finish selecting. Frostle snapshots your entire screen the instant you hit the hotkey and lets you select from that frozen still. Nothing moves while you work.

How is this different from Claude Desktop or Copilot?

They grab the live screen and give you a general chat. Frostle is purpose-built around the freeze-frame gesture, six focused modes, voice input, link reading, and the option to bring your own keys with no single-vendor lock-in — wrapped in a fast, premium Windows experience.

Which AI powers it?

Best-in-class vision models read and reason over your screenshots, with fast, accurate voice transcription built in. Free runs a quick model; Pro runs a smarter, sharper one. Bring your own keys for full control and no single-vendor lock-in.

Where do my data and keys live?

Your chat history stays on your computer. If you bring your own API keys, they’re stored in the Windows Credential Manager — never in a plain file. Captures are sent to the AI provider only to generate your answer.

Do I need an account?

Yes — a quick Google sign-in manages your plan (Free, Pro, or bring-your-own-key). Even on BYOK, your captures and chat history stay on your machine and your API keys live only in the Windows Credential Manager; the account just handles billing.

Mac or Linux?

Frostle is Windows-native today (Windows 10 & 11), built to feel right on Windows first. Other platforms may follow based on demand.

The deep end

Freeze it. Ask it.
