kada: One tap to Record
Voice notes for your AI
Free · Designed for iPhone. Not verified for macOS.
Record, transcribe, and connect. The new Agents tab and native setup guide help your AI work with your notes. Start recording without an account.
Use the Action Button on a supported iPhone or Apple Watch to record your thoughts, transcribe them in Cloud, and connect your AI agent to work with your notes.
YOUR THOUGHTS, READY FOR YOUR AI
Kada makes your everyday thoughts useful context for your AI. Capture an idea before it disappears, turn it into text, and bring your notes into the way you think and work.
SMART NOTE MERGING (BETA)
Let AI bring related thoughts together. Smart Note Merging helps organize related Cloud notes so ideas recorded at different moments can come together. For supported accounts, turn on Auto Note Merging (Beta) in Settings > Cloud notes.
RECORD. TRANSCRIBE. CONNECT.
Record on iPhone or Apple Watch without signing in. Use the on-screen recorder, an Apple Shortcut, or the Action Button on a compatible device. The floating setup guide helps you assign Kada to your Action Button.
Sign in on iPhone for optional Cloud transcription. Before your first upload, review where your audio goes or choose to keep that recording on your device. After you accept, new recordings upload automatically and appear in the Library with searchable transcripts and summaries. Declining skips that upload; the next new recording asks again. Your recordings are saved on your device too. Older recordings upload only when you select them.
AI processing follows the region assigned to your account when it is created. New accounts created through the mainland China App Store use regional AI services for transcription, summaries, and smart note merging. Existing accounts keep their assigned region. Cloud upload information and Help identify your account’s provider.
Open the Agents tab for a native connection guide, connected agents, approval codes, and access keys. Connect a compatible AI agent and approve its access to the text of your Cloud notes. You control its permissions and can revoke access. You can also copy or share transcript text with your preferred assistant, giving it the context to help you explore an idea, organize your thinking, or decide what to do next.
CAPTURE WITH LESS FRICTION
Stay in the moment with a full-screen recorder on iPhone, your choice of animation, and clear pause, resume, and finish controls. The optional welcome guide lets you record immediately or learn about Cloud, sign-in, and the Action Button. Find the guide again alongside recording tips, Watch setup guidance, and feedback options in Help.
The included Apple Watch app records independently. Pair the Watch with your account through your iPhone to upload new Watch recordings to Cloud. Local Watch audio does not transfer directly to iPhone.
YOUR CONTEXT, YOUR CHOICE
Choose what to remember alongside a recording. Location, motion, and health readings are optional and off until you enable them. After you accept Cloud uploads, new iPhone Cloud recordings include their saved context, including time, device details, and any optional data you chose to collect. Watch context sharing remains an independent choice, off by default. Older recordings require a separate choice to share context.
