Free plan, no card · Works with ChatGPT and Claude

Your AI knows everything.
Except your day.

Kioku is a quiet Mac menu-bar app that records your meetings, calls, and screen into a private archive — then plugs that archive into ChatGPT or Claude. Ask what was said yesterday. Get the actual sentence back, with the time it was said.

macOS 14 or later · Signed and notarized by Apple · Free plan includes 1 hour of recording every week

Ask about yesterday. Get the actual sentence, with a timestamp.

Kioku connects to ChatGPT and Claude as an MCP connector. There is no new app to learn — you get answers about your own week in the chat window you already have open.

Illustrative examples — constructed to show the shape of an answer. Not customer data.

Read-only, by design. It can search and read your archive. It cannot start or stop capture, change your data, delete anything, or send email.

Notetakers give you notes.
Kioku gives your assistant a memory.

An AI notetaker joins a meeting, writes a summary, and leaves it in an app you have to remember to open. Kioku is doing a different job: it builds the half of your assistant’s context that’s missing — the half that happened to you.

No bot joins your call

Nobody else has to install anything or watch a notetaker appear in the participant list. Kioku captures from your Mac. Before you record, you must tell everyone who will be recorded and obtain their agreement.

Not only meetings

Most of what you need later never had a calendar invite: the call you took at your desk, the contract you skimmed at 4pm, the number someone said once and nobody wrote down. Kioku captures the audio around your Mac and what’s on its screen, so all of it is answerable.

The answer comes to you

You don’t open Kioku to search. You ask ChatGPT or Claude, in the window you already have open, and the answer comes back with the moment it came from.

Nothing to open. Nothing to search. You just ask the assistant you already use.

Tuesday, as remembered.

You started capture once in the morning and forgot about it. You didn’t take a single note. Here’s what was waiting for you anyway.

  1. 09:12

    Standup, 14 minutes

    Four people, three blockers, and a ship date that quietly moved to the 14th.

  2. 10:40

    You read the vendor contract

    Section 7 says thirty days’ written notice. It was on your screen for ninety seconds. Kioku read it too.

  3. 12:05

    Lunch

    Marked low-signal and hidden. Nothing to review, nothing to delete, nothing to skim past tomorrow.

  4. 14:30

    Client call

    They pushed on pricing. You said you’d send numbers Thursday. That’s an action item now, with the exact sentence attached.

  5. 16:50

    Someone stopped by your desk

    Your designer said the button should be secondary, not primary. Nobody wrote it down. It’s in there.

  6. 18:15

    Laptop closed

    On the train, from your phone: “What did I promise the client today?” ChatGPT answers out of your archive.

You did none of this. You had a Tuesday.

An illustrative day. Capture runs while you have it on — you start and stop it from the menu bar, and macOS shows its own recording indicator whenever a microphone is live.

Three steps. About two minutes.

01

Install the Mac app

Download Kioku and sign in with Apple or Google. It lives in your menu bar and then gets out of the way. macOS 14 or later, signed and notarized by Apple, and it updates itself.

Download free for Mac →
02

Start capture and let it run

Start capture from the menu bar once and get on with your day. What comes back is memories: transcripts with who said what, the people you talk to, the action items you agreed to, and a recap of what actually happened.

Pure Swift capture clients package bounded audio and timestamps. The Mac adds screenshots and available browser context; the iPhone records microphone audio only. Understanding — transcription, diarization, OCR, and Mac screenshot understanding — runs on Vertex Gemini in Kioku’s attested cloud service, not on your Mac.

03

Connect ChatGPT or Claude

Add Kioku as an MCP connector and approve read-only access. Then ask your assistant something only you would know: “What did I work on this morning?”

Connection guide →

No calendar to configure. No bot joining your calls. Nobody else in the meeting has to install anything.

Your day is private property. Queryable memories live in private, encrypted Cloud SQL and large raw media is separately encrypted per user before GCS storage. Public TLS and application processing run in an open-source, hardware-attested Google Cloud enclave fleet. Cloud SQL and authorized administrators are part of the structured-data trust boundary. Raw audio and screenshots are scheduled for deletion after 30 days. Kioku does not sell your personal information, use your private archive for advertising, or train a Kioku model on your archive.

The questions you’re actually asking.

Do I need ChatGPT or Claude to use this?

No. The dashboard at kiokuu.com/app is a full memory browser on its own — memories, the people Kioku has learned, and a live feed of what’s been captured. But the connector is what Kioku is built around — asking your assistant about your own week, inside the tool you already work in.

Is it recording all the time?

Only while you have capture on. You start and stop it from the menu bar, and macOS shows its own recording indicator whenever a microphone is live.

Does it run on my Mac or in the cloud?

Both, and we’re specific about it because a lot of products aren’t. The Mac app captures and uploads. Transcription, diarization, OCR and screen understanding run on Vertex Gemini in Kioku’s cloud. If you need everything to stay on your own machine, Kioku isn’t the right tool for you today. Full detail on the security page.

Do the people I talk to know?

Only if you tell them. Kioku doesn’t join calls and doesn’t announce itself, which means that responsibility is yours, not ours. Recording rules vary by state and country, and several places require everyone’s consent. Saying “heads up, I keep a transcript” takes four seconds and is the difference between a tool and a problem.

What can ChatGPT or Claude actually see?

Only what it asks for, and only to read. It can search your archive; it cannot start or stop capture, edit anything, delete anything, or send email. Kioku also refuses assistant searches aimed at sensitive categories — payment-card data, health information, government identifiers, passwords, API keys, tokens and authentication codes — and redacts incidental matches before anything leaves. Full detail on the security page.

Do you train AI on my recordings?

No. Kioku does not sell your personal information, use your private archive for advertising, or train a Kioku model on your archive.

What happens if I run out of hours?

Your weekly allowance stops new cloud capture until it resets. There are no overage charges and no surprise bills, and you can change plans at any time from Settings.

What happens to my archive if I downgrade or stop paying?

It stays. Your weekly recording allowance returns to the free tier, but Kioku doesn’t delete your archive for going quiet. It’s there until you delete your account, and you can export it from Settings whenever you like.

Who else is using this?

Not many people yet, and we’re not going to paste a row of logos we haven’t earned. Kioku is early. That’s why the free plan exists with no card attached — one week of your own real days is a better argument than any testimonial we could put here.

Is there an iPhone app?

Kioku for iPhone records microphone audio only and is in limited private testing. It is not on the App Store, so there is nothing to install there today — Mac is where Kioku is real. When iPhone opens up it will connect to this same archive.

Start free. Upgrade when you stop wanting to live without it.

One allowance covers your whole recording timeline — not each microphone, not each track. No overage charges. Cancel any time.

The free plan needs no card. Apple processes subscriptions purchased in the iPhone app; Paddle processes web purchases. Kioku routes changes and cancellation to the provider that holds your subscription.

On iPhone, Apple in-app purchase is offered for eligible plans. A permitted U.S. web option may appear alongside Apple’s options and is processed by Paddle. The annual web prices labeled above are billed yearly through Paddle. App Store prices are localized by Apple and may differ. Every recording allowance resets weekly.

Your assistant is one download away from knowing your week.

Install Kioku, start capture, have one real conversation, then ask ChatGPT what you agreed to. That’s the whole demo, and setup takes about two minutes.
