AI DICTATE — Speak. Write. Done.
─────────────────────────────────────

Hold your keyboard shortcut (Alt+D on Windows, Option+D on Mac), speak your thoughts, and watch VoicePen instantly transcribe and refine them into polished prose — directly in the page you're on.

• 5 output modes: Default, Email, Notes, Casual, Professional 
• Real-time dynamic refinements as you speak 
• Change style mid-dictation by voice ("make it more formal", "rewrite as an email") 
• Voice editing commands ("delete the last sentence", "make this shorter", "summarize what I just said") 
• AI suggestions read aloud while you dictate 
• Snippets: speak a trigger phrase to auto-expand frequently used text • Output in any of 40+ languages — dictate in one language, write in another 
• Works inside any text field — no copy-pasting required

AI NOTES — Capture knowledge without breaking your flow
─────────────────────────────────────

Trigger Notes AI (Alt+N), speak your note, and it handles the rest. It reads the page, understands your intent, and files your note exactly where you want it. 

• Voice-first capture — speak and it saves instantly 
• Smart page capture — summarize articles or save your selected text 
• AI creates new note categories on the fly based on what you say 
• Split a long article into multiple topic notes with one voice command 
• Generate Q&A study cards from any page ("create 10 learnable notes from this article") 
• Attach the page URL and title to any note automatically 
• Color-coded categories, fuzzy search, sort by date 
• Everything stored locally — browse and review your notes from the extension

BYOK — BRING YOUR OWN AI API KEY
─────────────────────────────────────

Use different models - OpenRouter integration coming soon 

VoicePen AI does NOT charge a monthly AI usage fee. You connect your own OpenAI API key and pay OpenAI directly — pennies on the dollar compared to any bundled AI SaaS subscription.

Real-world cost: I used VoicePen AI every day for a full week and spent $0.05 in OpenAI API charges. That's not a typo. Typical AI tools bundle AI access into a $10–$20/month subscription. With BYOK you cut that cost by 95% or more.

Why BYOK is the smarter choice:
• Your requests go directly from your browser to OpenAI — no middleman 
• Faster responses — no round-trip through a third-party relay server 
• Full control over your spending — set usage limits directly in your OpenAI account • 100x+ lower cost compared to typical bundled AI services

PRIVACY FIRST — Your data never touches our servers
─────────────────────────────────────

Every piece of sensitive data stays on your device: 

• API keys are encrypted with AES-256-GCM and stored in your browser's local storage — they are never sent to our servers or any third party 
• Your notes and dictation history are stored locally in your browser 
• Voice requests travel directly from your browser to OpenAI — VoicePen's servers are never in the loop 
• Your license key is encrypted and stored locally — never exposed

VoicePen AI injects into any webpage. No context-switching, no copy-pasting.
