ThinkCapture
Read full descriptionHide full description
A link to read later. A task you can't forget. An idea that just popped into your head. Do you keep each of these in a different app? ThinkCapture is one place to drop all three. You don't pick where things go: whether it's a link, a task, or a passing thought, the AI on your device reads it and files it. You never classify. You never tag. You just write. ■ Three apps, in one - Links to read later — send a URL from the share sheet; it's saved with a headline and thumbnail. - Things to do — write "reply to Sam" or "buy milk" and the AI treats it as a task; add a due time and it reminds you. - Ideas and notes — thoughts, things you've learned, and what happened today all go in the same field, and they stay. ■ Why keep them together Storing things separately means deciding, every time, which app this belongs in — enough friction that you often don't write it down at all. Put it all in one place and it becomes impossible to find. Make sorting the AI's job and both problems disappear — and since the sorting never leaves your device, you can pile up anything without worrying. ■ What you can do - Instant capture — write in a single field; saving finishes at once, without waiting for the AI. One tap from Siri, Shortcuts, widgets, or Control Center. - On-device sorting — each note becomes a task, idea, knowledge, reference, journal, waiting, or someday item. Override any result; when it isn't sure it says "unclassified" instead of guessing. - Full-text search — find anything by keyword or tag name, completed items too. - Today — no cluttered inbox. Just today's tasks and your recurring habits. - Calendar — see the days you wrote on, and overlay events from your device's calendar (iCloud, Google, and more). Events are displayed, never changed. - Tags and priority — add your own tags on top of the AI's categories, and set high, medium, or low priority. - Due dates and reminders — set one in a tap; add a time and you get a notification. Recurring reminders too. - Photo attachments, plus a grid layout like paper in a notebook. - Home Screen widget — check today's tasks and capture without opening the app. - Backup and restore — export everything as JSON or Markdown anytime and import it back; restoring merges, never deletes. - iCloud sync (optional, off by default) — only about where data is stored; sorting still runs on device. ■ Pricing Writing, sorting, searching and exporting are free, with no limit on how much you capture. Everything above stays free and unlimited. ThinkCapture Pro is an optional subscription for how the app looks and where it lives: color themes (green, blue, purple), a board view that flips through your Inbox column by column, and a Lock Screen card for checking off today's tasks. In Japan it is ¥2,500 per year (about ¥208 a month, roughly 48% less than monthly) or ¥400 per month; your region's price is shown in the app. The yearly plan starts with a 14-day free trial for people new to the subscription. Both plans renew automatically unless cancelled at least 24 hours before the period ends, and you can cancel anytime under Settings > your Apple Account > Subscriptions. Without Pro, nothing is locked away and nothing stops you from writing more.

What you write is never sent to an outside server to be classified, and no account is required. Saving a link fetches only that page's public headline and thumbnail. ■ Requirements Automatic sorting requires iOS 26 or later on an Apple Intelligence–capable device. On other devices you tap the classification badge to pick a category by hand — it still works as an ordinary notes and tasks app. Don't classify. Don't organize. Just write.
Kakesu

Toss links in, dig them out later. That is the whole app. The jay hides each acorn in a different place and remembers what it hid, where, and when, so it can dig them out later. Kakesu is named after that bird because it does the same job. SAVE FIRST, TITLE LATER The moment you send a link from the share sheet, it is already saved. The page title and image are fetched afterwards. Even on a bad connection, the save itself does not fail. NO ACCOUNT No email address, no password. What you save goes into your own iCloud. Sign in with the same Apple Account on another device and your list is there. TOOLS FOR DIGGING THINGS BACK OUT - Search titles, URLs, tags, notes and page text together - Filter by tag - Separate unread and favorites - Reorder by dragging - Mute what you do not want to see (by a string in the URL or title) - Thumbnails appear only when there is one. No empty frames ASK, ON THE DEVICE ONLY Ask about what you have saved, in your own words. Try “what have I saved lately?” and the bookmarks behind the answer are listed underneath. Follow up with “when did I save that?” and it answers with the earlier exchange in mind. It runs on the device's own model, so neither the question nor the answer leaves the phone. Available on devices that support Apple Intelligence. DECIDE WITH A SUMMARY, BEFORE YOU READ Press and hold an item and choose “Summarize”. You get a summary drawn only from that page's own text, and you can keep asking about it. It is there to help you decide whether the article is worth reading. The summary and the conversation are both made on the device. Available on devices that support Apple Intelligence. KEEP IT PRIVATE If you ever hand your phone to someone, turn on the app lock. Opening the app then asks for Face ID / Touch ID, or your device passcode. It does not ask when you come back from a link you just opened. Off by default. YOU KEEP A COPY Once a week the whole list is written as JSON into iCloud Drive. You can open it in the Files app, and it stays there even if you delete the app. It is only read back when you ask for it in Settings. WHAT YOU SAVE IS YOURS The URLs you save are your browsing history. They are not sent to the developer. There is no server to send them to. Syncing is left to Apple's iCloud.

Verdict
The clearest difference is in-app purchases: Kakesu at none against ThinkCapture's 2. Kakesu also leads on update cadence (every 3 days vs weekly). On price, ads, device support and iOS requirement there is nothing between them.
