Your tasks, notes, and calendar shouldn't live in three different apps. Claira keeps them in one place — the school form buried in your inbox, the appointment next Thursday, the packing list for the trip, the idea you don't want to forget. Capture anything, organize later. Ask Claira anything "What's on my plate this week?" Claira reads your own tasks, notes, and calendar and answers — and searches the web when it needs to, with the sources right there to tap. "Add that to the note." It drafts the change and waits for your okay. Keep everything together Keep the tasks, notes, events, and chats for a project, a trip, or the kids' stuff in one place — like a folder, but for more than files. We call each one a bubble, as in a thought bubble: everything on your mind about one thing. Capture first, organize later Type, dictate, or share from any app — the iOS share sheet, voice, photos, PDFs, Office files. Claira transcribes voice and fills in fields like title and date. Capture works offline and syncs when you reconnect. Forward an email. Claira finds the to-dos. Claira gives you a private address. Forward or CC any message and the tasks and events hidden inside come back as cards you accept with a tap. Need the gist of a long newsletter or PDF? Tap once for a summary. Tasks and notes, one editor One editor for both — no app-switching. Started a note that's really a task? Convert either direction. Swipe to schedule for today; set tasks to repeat — daily, weekly, monthly, or custom; reminders nudge you at the right time. Don't know the date yet? Park it in "In a week" or "Someday." Plan your day on the timeline Organize your day on a timeline — drag tasks and events into place, timeboxing when each one happens with a quick drag & drop. Your iPhone and Google calendars show up right next to your tasks. End the day with a clear head Journal is a short evening check-in: how the day felt, what's on your mind, an optional photo. Look back anytime to see how things have been going. Spaces for every part of your life Home, work, side projects — give each its own Space, with the tasks and notes that belong there. Switch in one tap; nothing mixes together. Share a Space with your partner or family, and everyone sees changes live. Find anything, fast One search across every task, note, and event. Type a name, a topic, or a time — “today,” “this week,” “past due” all work. Claira widget Add the Claira widget to your Home or Lock Screen to see today's agenda and your next event.

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.**

The clearest difference is in-app purchases: BTS Chatter at none against Claira's 2. BTS Chatter also leads on device support (4 vs 1). Claira's advantage is update cadence (every 5 days vs monthly). On price, ads and iOS requirement there is nothing between them.
