Private On-Device AI Meets Microsoft Copilot

Your lectures and meetings are transcribed 100% on your PC with local Whisper AI — your audio never leaves your device. When you want a summary, one click sends the transcript to Microsoft Copilot (or ChatGPT, Claude, Gemini). You decide what is shared, and when. On PCs with a dedicated graphics card, transcription is GPU-accelerated with Vulkan.

🌍 99 languages supported — automatically detected and transcribed entirely offline on your PC.

StashWhisper v1.0.2

Local transcription, cloud summaries — on your terms.

Large V3 Turbo: 99 languages, 100% offline

With Auto-detect, the multilingual Large V3 Turbo model recognizes the spoken language and transcribes 99 languages — including Turkish — entirely on your PC. No internet connection and no audio upload needed. Vulkan GPU acceleration on dedicated NVIDIA, AMD and Intel Arc graphics cards unlocks Turbo; without a dedicated GPU, StashWhisper uses the CPU automatically.

Send to Copilot

One click copies your transcript with a ready-made summary prompt and opens Microsoft Copilot. Paste, and get a concise summary with key takeaways and action items. Nothing is sent until you paste and submit it yourself.

Built for focused learning

Your lecture is transcribed on your computer. Your notes stay with you.

StashWhisper transcribes locally with whisper.cpp, then gets out of the way — one click packages your transcript into a prompt you can hand to whichever AI assistant you already use.

🔒

100% Offline Transcription

Audio and transcripts are processed and stored on your local computer with whisper.cpp. Nothing is uploaded automatically — you decide what, if anything, to share afterwards.

One-Click Smart Prompt Export

Export a ready-made academic prompt — your full transcript, pre-formatted — as a .txt file in one click. Upload it to ChatGPT, Claude, or Gemini to get structured notes back.

Bring Your Own AI

StashWhisper builds the prompt; you choose the AI assistant. Paste its response back into the app and it's saved right alongside your transcript — no subscription, no lock-in.

🔐

Your lecture is your data.

Recording and transcription are 100% local: your audio and transcripts are processed and stored on your computer with whisper.cpp, and StashWhisper never uploads them automatically. If you choose to generate AI study notes, you decide which AI service to use and what to share with it — that step happens outside the app, on your terms.

FAQ

Questions, answered.

Where can I download StashWhisper?

Exclusively through the Microsoft Store — we don't offer a direct .exe download. Installing, updating, and (once available) purchasing Pro all happen through the Store, which also handles license verification and Store-based refunds.

Is my audio uploaded to any server?

No. Recording and transcription are 100% local — your audio files and transcripts are processed and stored on your computer with whisper.cpp and are never uploaded automatically.

How do AI Study Notes actually work?

StashWhisper does not run its own note-generating AI. Instead, one click exports a ready-made prompt — your transcript, pre-formatted — as a .txt file. You upload that file to the AI chat service you already use (ChatGPT, Claude, Gemini, or any other), copy its response, and paste it back into StashWhisper's "AI Study Notes" tab to save it with your session.

What are the system requirements?

Windows 10 or 11 with at least 8 GB of RAM. StashWhisper checks available memory on launch and during setup — below roughly 7.5 GB of usable RAM, the app can still be installed, but live transcription stays disabled until you're on a machine that meets the requirement.

How does the free trial work?

You can use the full StashWhisper workflow for 3 complete sessions before purchasing a Pro license.

Can I use StashWhisper without an internet connection?

Yes, for recording and transcription — both run entirely offline. An internet connection is only needed for the optional step of uploading an exported prompt to an AI chat service to generate study notes.

How do I activate my Pro license?

Click "Upgrade to Pro" in the app and choose "Buy Pro." The purchase runs through the Microsoft Store (the same account you used to install StashWhisper), and your license is tied to that account, so it is restored automatically if you reinstall; see our Terms of Service and Refund Policy for how Store purchases and refunds work.
