System design
Compares leader-based, multi-leader and leaderless replication, and what each one gives up when a node fails or the network splits.
Save articles, PDFs, notes and recordings to one library. Qind tags each one and files it when it is sure, then answers your questions with links back to the source.
Free plan, no card needed.
The article sits in a bookmark folder, the PDF in Downloads, the screenshot on your desktop. When you need it, it is nowhere.
Qind gives everything you save one home. To get something back, you ask for what you remember, in your own words.
Clip a page or a highlight with the browser extension, upload files, write a note, record audio, or save straight from Claude or ChatGPT through MCP. Everything lands in one library.
Set up the web clipper
Each item gets tags from what it says and moves into the collection it belongs to. Items Qind is unsure about wait in Unsorted for you. Turn on summaries and every item also gets a short summary.
How Qind organizesDesigning Data-Intensive Applications, ch. 5
Unsorted
System design
Compares leader-based, multi-leader and leaderless replication, and what each one gives up when a node fails or the network splits.
Ask the way you remember it. Qind searches by meaning and by keyword, answers from your own items, and cites each one so you can open the source and check.
The demo runs on sample items. Choose a question to replay it.
More on search and AskPages, PDFs, Office files, notes, images, audio and video go through the same library. Audio is transcribed and images get a caption, so both turn up when you search.
Qind sends a weekly or monthly digest of what you saved and what still needs a tag or a home, by email and in the app.
Weekly digest
A heavy week for systems design: five articles and two papers on cell-based architecture. Your API design collection grew by four items.
Items Qind is confident about go straight into the right collection. You can move anything, rename anything, or switch auto-filing off.
Point a question at a single collection when you want answers from one project only.

Compare plansQind is a personal AI knowledge base: save notes, PDFs, articles and recordings, and ask questions about them. It is not a team wiki or a project tracker; it is the place where what you read and keep stays findable. These pages explain the ideas behind it and compare it honestly with the tools you may use today.

Your data travels over encrypted HTTPS connections, and you can export it or delete your account at any time. Qind is not end-to-end encrypted: content is processed on Qind’s servers so it can be tagged, summarized and searched. The privacy policy lists every processor involved.
No. Qind does not train models on your saved content. The privacy policy lists the AI providers and what each receives.
Bookmarks store links. Qind keeps what is behind them: it tags each item, files it in a collection, can summarize it, and answers questions across everything you saved with links back to the sources. The Free plan lets you judge it on your own reading before you pay anything.
Keep Notion or Obsidian for writing and planning what you create. Use Qind for the articles, PDFs, papers and pages you read, so you can find and ask about them later without filing anything by hand.
Yes. Import your browser bookmarks with the web clipper, and upload files several at a time: export from your current tool as Markdown, HTML or PDF and drop them in. Direct imports from Google Drive, Notion, OneDrive, Evernote, Raindrop and Obsidian are planned but not available yet.
Yes. Request an export from your account settings at any time. It is prepared in the background, and you get a downloadable archive of your data.
Create an account, add the web clipper, and save one article today. Next week, ask Qind about it.
