About

VoiceNote

VoiceNote is the fastest way to get a thought out of your head. Tap record, say it out loud, and you have a clean note in seconds. No typing, no setup, no account. When you stop recording, VoiceNote writes down what you said, tidies up the rambling, and gives the note a title and a short summary. If you mentioned something to do, it pulls that out as a to-do, and any event you mention is one tap away from your calendar. The part people like most: you can ask your notes questions. Open the chat and type something like "what did I decide about the trip?" or "what have I been meaning to read?", and VoiceNote finds the notes that matter and answers from them. It shows you exactly which notes it used, so you can check its work. Everything happens on your iPhone. Your recordings, your transcripts, and your questions never leave the device. There is no server, no account to create, no API key to paste in, and nothing to pay for. It works on a plane with the wifi off. That is possible because VoiceNote runs entirely on Apple's own on-device speech and intelligence frameworks. What you can do: - Record a thought and get a clean, titled note back - Replay the original audio any time, or add more to a note later - Read and edit the transcript yourself - Ask questions in plain language and get answers grounded in your notes - Turn spoken to-dos into reminders and calendar events with a tap - Search and browse everything by date VoiceNote is small on purpose. It does a few things and tries to do them well: catch the thought, clean it up, and let you find it again later just bye asking. Free, private, and yours.

Chatter - Your agents. Your tools. Your data. Chatter is the AI chat app we built for ourselves - because we wanted frontier-quality answers without handing our conversations to yet another data-hungry platform. Now it's yours too. Chatter runs on Ollama Cloud with zero data retention: your prompts and answers are processed, streamed back, and gone. Nothing stored server-side, nothing used for training. Just fast inference on powerful open models - and a native, lightweight app on iPhone, iPad, and Mac that stays out of your way. Private by design. No account, no sign-up, no login - enter your API key and start chatting. We collect nothing: no analytics, no tracking, no telemetry. Your chats, agents, and knowledge live on your devices and sync exclusively through your personal iCloud (Apple CloudKit), end-to-end within your own Apple ID. We couldn't read your data if we wanted to - and we don't want to. Build your own agents. Create assistants with their own personality, model, and toolset - a coding expert, a research companion, a home-automation operator. Each agent is exactly as capable (and as locked-down) as you decide. Give them tools with MCP. Connect any Model Context Protocol server - self-hosted on your LAN, over Tailscale, or anywhere else. Your agents can query your databases, control your smart home, or reach your internal APIs. Your infrastructure stays yours. Give them knowledge. Attach curated knowledge bases to any agent - import PDFs or Markdown, and your agent reads exactly the documents it needs, when it needs them. Watch them grow. Agents remember what matters: they keep their own notes about you and your projects across chats, and they can even write down reusable skills - procedures you teach them once and they follow forever. You stay in control: everything they learn is visible, editable, and deletable. Everywhere you are. One app for iOS and macOS, with your agents, chats, and knowledge synced privately through iCloud. No subscription. No middleman. No tracking. Chatter is a native client for your own Ollama Cloud account - bring your API key, and own your AI. **Requires an Ollama Cloud API key (ollama.com). Chatter connects directly to Ollama Cloud and to MCP servers you configure; we run no servers of our own.**
