Create AI agents that watch your screen, camera, or listen to audio, and take action when something happens.

HOW IT WORKS 1. Choose Sensors: Screen capture, camera, microphone, clipboard, or audio 2. Pick a Model: Connect to local models via Ollama, llama.cpp, vLLM, or use cloud inference 3. Set Actions: Configure notifications, memory logging, or video recording when conditions are met EXAMPLE USE CASES - Person detection alerts via Telegram when someone appears on camera - Smart screen monitoring that notifies you when specific content appears - Meeting transcription and logging - Custom automation triggered by visual or audio cues NOTIFICATION CHANNELS - Discord - Telegram - WhatsApp - SMS - Email - Phone calls (VoIP) - Pushover - Browser notifications PRIVACY-FIRST DESIGN Observer AI is 100% open source. Run entirely local with your own inference server and Discord webhooks, zero data touches our servers. For maximum privacy, compile from source and use local models. FEATURES - Visual and audio sensor inputs - Local LLM support (Ollama, llama.cpp, vLLM, LMStudio) - Cloud inference option for convenience - Agent memory system for context retention - Video clip recording and marking - Community agent sharing - Background operation OPEN SOURCE Full source code available at https://github.com/Roy3838/Observer App Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Platform Terms of Service: https://observer-ai.com/#/terms Privacy Policy: https://observer-ai.com/#/privacy

stop typing. start yapping. YapRun is a voice-to-text keyboard that runs entirely on your device. no cloud. no subscriptions. no random server in Virginia listening to your voice notes. just pure, on-device AI transcription that works anywhere you can type. here's the deal — you install YapRun as a keyboard, tap the "Yap" button, and talk. your words appear as text. that's it. no account signup. no email verification. no "start your free trial." it just works. AND YES — YOUR DATA STAYS ON YOUR PHONE. we're not being dramatic. the AI model literally runs on your iPhone's Neural Engine. your audio never touches a server. never gets uploaded. never gets "anonymized and used to improve our services." it stays on your device, gets transcribed, and the audio is immediately discarded. period. — WHAT YOU GET: → Custom Voice Keyboard install YapRun as a system keyboard and use voice dictation in any app — Messages, Notes, WhatsApp, Slack, literally anywhere you type. tap "Yap", talk, done. → Multiple AI Models choose between speed and accuracy. the "Fast" model runs on Apple's Neural Engine with almost zero battery drain. the "Accurate" model gives you better results for longer dictation. you pick what works for you. → Works Everywhere once you set up the keyboard, it works in every single app. iMessage, email, social media, whatever. your voice, your text, your rules. → Live Activity Support see your dictation status right on the Dynamic Island or Lock Screen. know exactly when YapRun is listening, transcribing, or done — no guessing. → ASR Playground want to test how good the transcription is before you commit? open the built-in Playground, hit record, and see the results in real-time. nerd out to your heart's content. → Notepad a simple built-in text editor for testing or quick notes. switch to YapRun keyboard, start talking, see your words appear. → Dictation History every transcription is saved locally so you can go back and copy anything you've dictated. your history, stored on your device, nowhere else. → Undo / Redo made a mistake? undo the last dictation. changed your mind? redo it. simple. → Word Stats track how many words you've dictated and how many sessions you've had. flex your yapping stats. — WHY YAPRUN EXISTS: most voice typing tools send your audio to the cloud. that means: • someone else's server processes your voice • your data exists on infrastructure you don't control • you need internet to use it • there's latency YapRun flips all of that. the AI runs locally using Apple's Neural Engine (or CPU if you prefer). no internet required after the initial model download. no latency from round-tripping to a server. no privacy concerns. we built this because we genuinely believe your voice data is nobody's business but yours. — SETUP TAKES 2 MINUTES: 1. open YapRun 2. allow microphone access 3. add YapRun keyboard in Settings → General → Keyboards 4. enable Full Access (required for the keyboard to work across apps) 5. download a voice model (one-time, ~70-134 MB) 6. start yapping Full Access is needed so the keyboard extension can communicate with the main app to activate the microphone. we don't use it to collect any data. ever. — POWERED BY RUNANYWHERE SDK YapRun is built on the open-source RunAnywhere on-device AI platform. same tech, open codebase, no secrets.
