Kioku is a personal knowledge library for Mac. Save articles, PDFs, websites, and your own Markdown notes into organized vaults you can read, search, annotate, and keep with you offline. Use Kioku to turn scattered research into a calm, durable library. Paste a URL to archive a single page, save a PDF from your Mac, or crawl more of a site when you want a deeper reference vault. Kioku stores your content as Markdown with downloaded assets, so your library stays portable and readable outside the app. Write your own notes with a focused Markdown editor, add images, create internal links, and keep authored notes separate from saved web pages. While reading, select passages to save excerpts and notes so important ideas do not disappear after the first pass. Kioku also includes optional local AI features for summaries, retrieval, chat, and study cards. Supported models run on your Mac, keeping those experiences local to your device.

About

Clair Mind

WHAT CLAIR MIND IS A private, local-first notes app. You capture a thought, it gets filed and titled for you, and over time you can see how your notes connect. Notes, notebooks, tasks and search all work fully offline and on-device. SIGNING IN โ€” PLEASE READ The app offers Sign in with Apple and Sign in with Google only; there is no password-based login, so there are no demo credentials we can supply. Please tap "Sign in with Apple" and use your own Apple ID โ€” account creation is instant, free, and requires no payment. Everything except the AI features works WITHOUT any account. You can install, capture notes, create tasks, browse notebooks and search with no sign-in at all. The AI features require an account because each request costs us money per call and is metered per user. Signing in is free and includes 1,000 words of AI per month at no charge. WHERE TO FIND EACH FEATURE - Capture a note: the round "+" button, bottom right of any tab. Type, then Save. The note lands in "Unsorted". - Create a task: same "+" button, then tap the checklist icon at the bottom right of the sheet to switch from note to task. - Ask AI: the "Ask" tab, centre of the bottom bar. Type a question about your notes. Requires sign-in. Past conversations are behind the history icon, top left of that screen. - Connections: open any note, then tap the flower icon above the note body. - Notebooks: the "Notebooks" tab. Tap any notebook to see its notes. - Tasks: the "To-Do" tab. Tap a list to open it; tap the circle on a row to complete it. - Your activity, plan and settings: the "Me" tab, then the gear icon, top right. FREE VS PRO - Free, after signing in: the entire app, plus 1,000 words of AI per month. - Pro (auto-renewing subscription): a much larger monthly AI allowance and voice capture (the microphone in the capture sheet and in Ask AI). - The paywall appears when the free AI allowance runs out, and from the "Unlock AI with Pro" row on the Me tab. - Restore Purchases: Me tab โ†’ gear icon โ†’ Account. ACCOUNT DELETION Me tab โ†’ gear icon โ†’ Account โ†’ Delete Account. It is a press-and-hold confirmation, then the account and its server-side data are removed. PRIVACY Notes live on the device. When you use an AI feature, the relevant note text is sent per-request to our AI provider to generate that one response; it is not stored server-side and is never used for training. This version adds analytics covering the first-run setup flow only, including a screen recording of onboarding with all typed text and images masked; recording stops before you reach your notes. Both are declared on the privacy label and in the app's privacy manifest, and described at https://clairmind.ai/privacy.
