Capture insights from
any video or screen.

Press a hotkey, select a chart, table, slide or stat, and Frostle turns it into a structured research note — with source links, timestamps and AI analysis. Save clips into projects and export a clean research memo.

Why not just use ChatGPT?

An answer box
forgets. Frostle
remembers.

Pasting a screenshot into a chatbot gives you an answer you'll lose by tomorrow. Frostle is faster at capture, keeps the source and timestamp, and files every insight into projects you can search and export. It's not an answer box — it's your screen-to-research memory.

  • Freeze-frame capture

    One hotkey freezes the whole screen — even a moving video or a popup that vanishes — so you can select the exact chart, table or stat that matters.

  • Source-linked clips

    Every clip keeps its screenshot, the page or video URL, and the exact YouTube timestamp — so you can always trace a claim back to where it came from.

  • Projects & export

    File clips into projects, tag and search them, then export a whole project as a clean Markdown memo for Notion, Obsidian or Docs. Everything stays local on your machine.

  • Keys stay in your OS keychain. API keys are stored in the Windows Credential Manager, never in a plain file. Privacy policy.

FAQ

Good questions

How is Frostle different from screenshotting into ChatGPT?

Frostle is built around workflow: hotkey capture, source links, timestamps, saved research clips, projects and export. ChatGPT can answer a screenshot; Frostle helps you build a reusable research library you can search and turn into a memo.

Does Frostle record my screen?

No. Frostle does nothing in the background. Only when you press the hotkey does it take a single still of your screen so you can select a region — it never records, streams or continuously watches your screen.

Are my clips and data local?

Yes. Your clips, projects and history live in a local database on your PC. If you bring your own API keys, they're stored in the Windows Credential Manager — never in a plain file. Only the region you select is sent to the AI provider to generate the answer.

Does the YouTube transcript always work?

Transcript support depends on availability — not every video has captions. Frostle still works with the screenshot and your selected visual context, and saves the source link and timestamp either way.

Can I export to Notion or Obsidian?

Yes. A single clip or a whole project exports as clean Markdown — paste it straight into Notion, Obsidian, Google Docs, or any editor. Source links and timestamps come along.

Do I need an account?

A quick sign-in manages your plan and lets Frostle run the AI for you. Prefer no middleman? Bring your own keys. Either way, your clips and history stay on your machine and any keys live only in the Windows Credential Manager.

Is there a Mac version?

Frostle is Windows-native today (Windows 10 & 11), built to feel right on Windows first. A Mac version is on the roadmap and will follow based on demand.
