Kioku lives on your Mac, quietly capturing what you hear and see — then lets you ask ChatGPT or Claude anything about your day, and actually get an answer.
macOS 14+ · Pure Swift capture · Encrypted cloud processing
Demo coming soon
Watch someone ask ChatGPT about their day — Kioku answers.
"What did the client say about pricing this morning?" — Ask your AI assistant anything. Kioku provides the context.
Download Kioku, sign in with Google in one click, and connect it to ChatGPT or Claude as an MCP tool. That's the entire setup.
Kioku’s pure Swift client packages bounded mic and system-audio snippets, screenshots, timestamps, and available browser context, then uploads them to the attested cloud service. Vertex Gemini handles transcription, diarization, OCR, and screenshot understanding there.
"Who was in my 2pm call?" — "What did we decide about the launch date?" Just ask. Kioku surfaces the moment from your archive and cites it.
The Mac and iPhone apps upload bounded audio, screenshots, timestamps, and available browser context to Kioku’s attested cloud service. Media is encrypted per user before persistent storage; Gemini handles media understanding, while persistent voice identity is learned inside the enclave.
Apple-native clients capture, encode, timestamp, spool, and upload. Transcription, OCR, diarization, identity learning, and indexing run in the cloud, with no Python, model, or local server in the Mac app.
Your text archive lives in a GCP Confidential Space VM (AMD SEV memory encryption). The per-user AES-256-GCM decryption key is only released to the exact, attested enclave image — not to us, not to GCP operators.
GCP Confidential Space · AMD SEVEvery user's database is encrypted with a separate key. Even in the unlikely event of a data breach, one user's data reveals nothing about another's.
The enclave image is open source. You can inspect exactly what code runs in the trusted environment and confirm that the attestation matches the published source.
Kioku quietly captures what you hear and see on your Mac, completely on-device. Free and open source.
