Knowledge Base
Read full descriptionHide full description
β Knowledge that grows on its own Just save the articles you find interesting β AI quietly compiles them into your own encyclopedia in the background. Knowledge Base is the gentle second brain that helps you graduate from "read once, forget forever." β Save from anywhere, in one step - Save articles directly from Safari or any app's Share Sheet - The + button also lets you add URLs, text, PDFs, photos (OCR), and audio (transcription) - Non-English or non-Japanese content is automatically translated into your chosen language before it's organized Saving finishes instantly β the heavy lifting happens in the background, so you're never kept waiting. β AI organizes key points by topic AI automatically creates and updates "concept pages" β your own personal wiki β across multiple articles. Open the Knowledge tab and topic summaries are always shown up to date. - The most important points come first, no tapping required - Related concepts link to each other automatically, so your knowledge connects - Every page can always be traced back to its original article β Chat that answers with citations "What did that article actually say again?" Ask the AI Chat. - Answers are generated only from the articles you've saved - Tap a citation number to jump straight to the source article - When general knowledge is used to fill a gap, it's always labeled clearly β Fix AI's mistakes in one sentence - Tap "Correct" on any article's detail page and describe the fix in plain language (e.g. "Claude Code is being misread as something else") - Unwanted concepts or tags can be edited, merged, or hidden anytime You always stay in control. β Privacy by design - All AI processing runs entirely on-device via Apple Intelligence - No ads, no tracking, zero data sent to external servers - iCloud sync uses only your own private database β A calm, considered aesthetic A palette of sumi ink and washi paper, elegant Mincho headlines, and breathing negative space inspired by seigaiha waves. Every time you open it, it feels quiet and refined. β Languages Knowledge Base supports 4 interface languages: English, Japanese, Simplified Chinese, and Traditional Chinese. AI-generated summaries, concept pages, and chat replies follow the same language, chosen automatically from your device's language on first launch (you can change it anytime in Settings > Generation Language). β Requirements (important) - AI features (automatic concept-page generation, AI Chat, summaries, translation, auto-tagging) require an iPhone that supports Apple Intelligence - Please turn on Apple Intelligence in Settings before use - Even without Apple Intelligence, you can still save, search, browse, and organize tags for your articles Now, put your iPhone's AI to full use and turn everything you read into knowledge that's truly your own.

Verdict
The clearest difference is in-app purchases: Knowledge Base at none against Cluspora's 2. Cluspora's advantage is iOS requirement (16.0 vs 26.4). On price, update cadence, ads and device support there is nothing between them.
