Think Faster Than You Type?
We Built This For You.
From writers to traders, discover how SynapseDeck transforms the way you work.
From Draft to Publish
in 10 Keystrokes
"I spend more time editing than writing. Every email takes 15 minutes of second-guessing."
SynapseDeck's Predictive Flow transforms your raw thoughts into polished prose as you type. Grammar fixes itself. Tone adjusts automatically. You write the idea — AI handles the craft.
Code in Any Language.
Document in English.
"Documentation is always the last priority. My code works but nobody understands it."
Press Ctrl+Shift+X on any code block. SynapseDeck's Explain agent generates JSDoc, docstrings, or README sections instantly. Works with 40+ languages. Runs 100% locally.
Invisible Encryption.
Zero Compromise.
"Every keystroke is logged by my employer's software. I have no privacy even on personal messages."
PGP Stealth Mode encrypts at the hardware level — before characters reach your computer. Screen displays decoy text. Only recipients with your key see the real message. RSA-4096 + AES-256.
Speak to Type.
Whisper-Fast Transcription.
"Voice assistants are slow and require internet. I need hands-free input that works offline."
Connect any Bluetooth headphones. OpenAI Whisper runs locally with <500ms latency. Dictate text, trigger AI agents, control automations — all by voice. PGP mode works with voice too.
One Keystroke.
400+ Integrations.
"I repeat the same workflows dozens of times a day. Copy here, paste there, click, wait, repeat."
n8n runs locally on your keyboard. Bind any workflow to F5-F12 keys. Press once — trigger complex multi-step automations across Notion, Slack, Email, Telegram, and 400+ more.
Control Everything.
From Any Device.
"I need to configure my keyboard but I'm on my phone. There's no app for that."
After boot, SynapseDeck OS opens a React 18 dashboard on your local network. Access from mobile or desktop. Manage all settings: WiFi, AI agents, LLM selection, n8n workflows, hotkey bindings.
Just Ask.
It Configures Itself.
"I don't want to dig through settings menus. I just want to tell it what I need."
SynapseDeck includes a Settings AI Agent. Type or speak naturally to manage every aspect: WiFi/Bluetooth connections, AI agents creation, LLM model selection, your own API keys, n8n automations, hotkey bindings.
Meetings to Actions.
In Seconds, Not Hours.
"I spend 4 hours daily in meetings but struggle to remember action items. My assistant can't keep up."
Whisper transcribes meetings in real-time. AI extracts action items, decisions, and deadlines automatically. One keystroke sends summaries to Notion, Slack, or email. Your meetings finally have ROI.
Your Papers. Your Data.
Never Leaves Your Device.
"I can't upload confidential research to ChatGPT. My institution forbids it. But I need AI assistance."
Build a local RAG system with your PDFs, papers, and datasets. Vector embeddings stored on NVMe. Query your entire knowledge base offline. Perfect for HIPAA, GDPR, and institutional compliance.
Milliseconds Matter.
Execute at Hardware Speed.
"Software macros are too slow. By the time my script runs, the opportunity is gone."
Keyboard-level macros execute in <1ms. No OS overhead. Program complex multi-key sequences for instant order entry. Combine with AI for real-time sentiment analysis of your RSS feeds.
Type. Speak. Command.
Three Paths to Brilliance.
Switch modes on the fly. All processing happens locally on your keyboard.
Predictive Flow
Type naturally. AI transforms your text in real-time as you finish each sentence — like T9 on ultra-max.
Hotkey Transform
Write your text, then press Ctrl+Shift+Key to invoke any AI agent. Grammar, translate, formalize, expand.
Voice Dictation
Speak to type. Local Whisper transcription with <500ms latency. Perfect for hands-free operation.
Your Second Brain.
Vectorized & Encrypted.
Obsidian-style markdown notes that live on your keyboard. Every note is vectorized into your personal knowledge graph — AI understands context across all your documents.
Vector Memory
ChromaDB embeddings index every note. Ask questions across your entire knowledge base — AI retrieves relevant context automatically.
PGP Encrypted
RSA-4096 encryption at rest. Only your key unlocks notes. Even if hardware is stolen — data is unreadable.
Selective Sharing
Choose what enters AI context. Toggle notes on/off from vectorization. Personal stays personal.
MCP Sync to Mobile
Your knowledge graph syncs via MCP protocol. Use Claude or ChatGPT on your phone — they access your keyboard's memory. Context follows you everywhere.
Whisper In. Voice Out.
Seamless Audio Intelligence.
Local Whisper STT + Piper TTS. Or connect ElevenLabs, OpenAI, or your own API.
Local TTS
Piper TTS runs on-device. 20+ voices, 10+ languages. Zero latency, zero cost, 100% private.
ElevenLabs
Ultra-realistic neural voices. Clone your own voice. Emotion control. Industry-leading quality.
OpenAI TTS
GPT-4 quality voices. Natural intonation. Whisper-powered. Seamless with OpenAI ecosystem.
Your API Key
Bring any TTS provider: Azure, Google Cloud, Amazon Polly, Coqui, or custom endpoints.
Real-World Scenario
You're coding and need hands-free assistance. Ask a question via voice → AI responds through your headphones while you keep typing. Like having a senior developer sitting next to you.

Three Tiers.
One Philosophy.
Drag the slider to compare configurations.
Your Brain Is Fast.
Your Fingers Aren't.
120 bits/s brain vs 10 bits/s typing. We close the gap.
AI amplifies your 10 bits/s → 100+ bits/s effective output
"The bandwidth between your brain and the machine is a huge limitation. We've got a very low data rate connection — you're basically communicating with the computer by moving your fingers around, which is insane."
Output Amplification
AI predicts intent, expands abbreviations, completes thoughts, and formats output.
One Device. Every Platform.
SynapseDeck connects as a standard USB HID keyboard. No drivers. No apps. Just plug and think.

Open Source Foundation.
No Vendor Lock-In.
SynapseDeck OS is fully open source. Audit, contribute, or fork — it's your keyboard.
Your Data Never Leaves.
Ever.
Four layers of security that work silently in the background.
Hardware Isolation
Keystrokes never reach your computer in readable form. Processing happens inside the keyboard's isolated ARM chip. Even with root access to your PC, attackers see nothing.
End-to-End Encryption
All data encrypted with RSA-4096 for key exchange and AES-256-GCM for symmetric encryption. Perfect forward secrecy — every session uses unique keys.
Zero Cloud Dependency
No account required. No telemetry. No analytics. AI models run locally on Ollama. Your data literally cannot be sold because it never leaves your device.
Open Source Auditable
Every line of code is on GitHub. Security researchers can verify our claims. No security through obscurity — we trust our cryptography, not our secrets.
What Beta Testers Say
About SynapseDeck
Real feedback from developers, writers, and privacy advocates testing the pre-release version.
Finally, an AI keyboard that doesn't send my keystrokes to the cloud. The local processing is incredibly fast, and PGP Stealth Mode is a game-changer for my work.
I replaced 5 browser extensions with one keyboard shortcut. Grammar, translation, code docs — all instant. My writing workflow has never been this smooth.
The n8n integration is brilliant. I automated my entire email triage workflow with hotkeys. What used to take 30 minutes now happens in 30 seconds.

Got Questions?
We Have Answers.
Do I need internet to use SynapseDeck?
No. All AI processing happens locally on the keyboard's Raspberry Pi. You only need internet for initial setup and optional cloud AI models (GPT, Claude). Local models work 100% offline.
Can my employer see what I type?
No. With PGP Stealth Mode, encryption happens at the hardware level — before keystrokes reach your computer. Even enterprise keyloggers see only decoy text.
What's the difference between editions?
Standard Edition is a stock Raspberry Pi 400/500 with our OS. Custom Edition adds aluminum heatsink case (+400MHz), dual microphones, speakers, E-Ink display bar, and 15-hour battery.
Can I use my own API keys?
Yes. BYOK (Bring Your Own Key) mode is always free. Add your OpenAI, Anthropic, or other API keys in the dashboard. Or use 100% local models with no keys needed.
Is it really open source?
Yes. SynapseDeck OS is MIT licensed. View the source, modify it, contribute back. Hardware schematics will be available for Custom Edition.
When does it ship?
Q2 2025 for first batch. Join the waitlist to lock in early-bird pricing and lifetime update guarantee for first 100 customers.
