## What is Second Brain TokKong?

Stuck on a 14-hour flight? Bad hotel WiFi again? No problem.

TokKong turns your voice into text anywhere in the world - no internet required. Powered by Whisper AI and on-device LLM, everything happens right on your iPhone or Mac. Your recordings never leave your device. Ever.

WHAT MAKES TOKKONG DIFFERENT

Most transcription apps send your audio to the cloud. We don't. Not a single byte. Whether you're recording a confidential meeting, a private memo, or that million-dollar idea at 3am - it stays between you and your phone.

FEATURES YOU'LL ACTUALLY USE

Talk & Transcribe
Hit record. Speak. Get text. It really is that simple. Works for meetings, lectures, interviews, voice memos, or that long voicemail you don't want to listen to. Export to SRT subtitles when you need them.

Drop In Any Audio
Got a voice message? Audio file? Video with speech? Drop it in, get text out. WhatsApp, iMessage, whatever - if it has voice, we'll transcribe it.

Translation That Works Offline
Yes, really. Translate speech between major languages without hunting for WiFi. Perfect for international trips.

AI That Polishes Your Words
Messy transcript? Our on-device AI cleans it up - punctuation, formatting, grammar. Your words, but better.

Custom Prompts - Your Voice, Any Format
This is where it gets wild. Create your own AI prompts and transform voice into ANY text format:

FOR DEVELOPERS (Vibe Coding)
Speak your logic, get actual code. "Create a Python function that sorts a list" - done. Set up prompts for code snippets, terminal commands, SQL queries, API requests, even git commits. It's like pair programming with your voice.

FOR BUSINESS PROS
Turn rambling voice notes into polished output:
- Meeting thoughts → formatted action items
- Quick ideas → professional email drafts
- Client calls → CRM-ready notes
- Brainstorms → organized project briefs

FOR CREATORS
Raw ideas → social posts, script outlines, show notes. Whatever format you need, just speak and let your custom prompt handle the rest.

Chat With Your PDFs
Upload contracts, reports, or research papers. Ask questions. Get answers. All offline, all private.

Quick Memo Mode
Brain dump mode. Capture thoughts fast. Find them later. Simple.

Hey Siri, Start Recording
Hands full? Use Siri Shortcuts. Launch transcription, start memos, process files - all voice-controlled.

Never Lose Anything
Every transcript saved. Searchable. Shareable. Organized. On your device where it belongs.

THE FINE PRINT (BUT GOOD)

- Works in airplane mode, submarines, or anywhere with zero signal
- No account needed. No sign-ups. No emails.
- Buy once, own forever. No subscriptions trying to sneak up on you.
- iPhone, iPad, Mac - pick your device
- Export to SRT, TXT, or just copy-paste

WHO'S THIS FOR?

The developer who wants to vibe code without touching a keyboard. The business traveler tired of airport WiFi. The journalist protecting sources. The student recording every lecture. The lawyer who needs bulletproof privacy. The creator with ideas at 3am. Or anyone who just wants their data to stay their data.

BEFORE YOU DOWNLOAD

TokKong runs AI locally on your device. For the smoothest experience, we recommend iPhone 15 or newer. Older devices work too - just a bit slower. It's physics, not a paywall.
