Hjarni Notes & Memory vs DeMinds

Your AI starts from zero every conversation. Hjarni gives it a memory built from notes you control. Write a note on your phone. Ask Claude or ChatGPT about it on your laptop, and it already knows. Hjarni is a Markdown knowledge base with a built-in MCP server. Notes, folders, tags. That is the whole product. MCP is not a plugin bolted on afterwards. The app was built around it. Call it a second brain, a personal wiki, a PKM system or a Zettelkasten. It is one place to keep what you know, in plain Markdown, so both you and your assistant can read it. HOW IT WORKS Save a note once. Connect Claude, ChatGPT, or any MCP client. Your AI reads your notes, follows your instructions, and writes new notes that fit your system. Save project decisions, preferences and research. Ask your assistant to remember something and it writes the note for you. Save a session summary to pick up where you left off, or turn finished work into a guide you can reuse. Stop re-explaining your stack, your customers, or your style guide at the start of every conversation. Write once. You both remember. ON YOUR IPHONE Capture a note in seconds from the New tab. Triage it later from the Inbox. Search everything you have written. Read anywhere. This is the capture and read-anywhere companion. The long editing sessions happen on the web. That is on purpose. ONE MEMORY, EVERY ASSISTANT Claude and ChatGPT each keep their own memory, and neither one shares. Hjarni sits outside both. Switch assistants, keep your context. Works with Claude, ChatGPT, Claude Code, Codex, Cursor, and anything else that speaks MCP. MEMORY YOU CAN ACTUALLY READ Assistant memory is a black box. Hjarni is not. Every note is plain Markdown you can open, search, and edit. Every change is versioned, so you can see what your AI wrote, diff it, and revert it. Export everything, any time, in a format that opens anywhere. SHARED NOTES FOR YOUR TEAM Team folders give everyone the same context. Your conventions, your decisions, your onboarding docs. Every teammate's AI reads the same thing, so nobody has to be the person who remembers. YOU OWN THE INSTRUCTIONS Set instructions per folder and per team. Tell your AI how to format notes, which tags to use, what tone to write in. Your AI works the way you work. SIMPLE BY DESIGN We left features out. No databases. No kanban boards. No page builders. Hjarni is a place to write and organize. The constraint is the feature. WHO IT IS FOR Developers, teams, founders, researchers, writers, travelers. Anyone who has typed the same context into a chat window twice. HJARNI PRO Hjarni is free to use, with a limit on how many notes you can keep. Pro removes the limit and adds file attachments, imports, email capture, and folder collaborators. Pro is an auto renewing subscription, monthly or annual. Payment is charged to your Apple Account at confirmation of purchase. It renews unless you turn off auto renew at least 24 hours before the end of the current period, and your account is charged for the renewal within 24 hours before that. Manage the subscription and turn off auto renew in your Apple Account settings. Terms of Use (EULA): https://hjarni.com/terms Privacy Policy: https://hjarni.com/privacy

Your content is still there. Your work should not have to start over. DeMinds is a local-first Markdown and mind map workspace. It brings files, web pages, mind maps, and shared links together as structured Markdown documents you can keep editing and reusing. Open supported MindNode, XMind, and FreeMind maps, along with Markdown, TXT, DOCX, HTML, and OPML documents. Choose content from a Markdown Package or Obsidian Vault. Hierarchy, links, and images are preserved whenever possible. With DeMinds, you can: • See the text and the whole picture On supported wide screens, read Markdown Preview or edit in Markdown or Rich beside the Universal Mind Map, even in Focus Mode. Jump from a node to its text while keeping your draft and Undo history. Saving refreshes the map and, where possible, keeps branches and Notes expanded or collapsed as you left them. • Adjust the structure directly In the Universal Mind Map, rename supported nodes, add siblings or children, and delete branches. Changes are saved in the same Markdown document. • Edit content and Notes Use Rich to edit supported text, images, code, tables and formulas visually, or Markdown for precise edits and unsupported content. Create, preview and edit node Notes in the same card. Complex tables from DOCX or HTML are read-only in Rich; edit their source in Markdown. In the document editor, add and reuse project images or delete saved images confirmed to be unused. • Bring in online content Open supported public documents, web and research articles, public ChatGPT share links, and X articles readable without signing in. Follow links from a public GitHub README to related Markdown documents. • Pick up where you left off Find projects by stage, time or Category in Continue Working. Compare or restore saved versions in Version History. Manually check public Feed or GitHub README Content Sources for updates. “Continue with AI…” prepares a file for an external AI tool, with an optional request for an AI Editorial Note. You share it yourself and compare returned edits before applying them. • Choose your Workspace Switch between Local Workspace and iCloud Workspace. Add selected missing projects without replacing existing ones; a full replacement needs separate confirmation. iCloud availability depends on your device and account. • Take your work with you Export a Markdown File, a Standard Markdown Bundle with assets, or a PDF. With DeMinds Plus, export a Full Mind Map as PNG, create a read-only Interactive View with text, map or both, and publish it publicly through GitHub Pages in your own account. Others can read it and download Markdown in a browser without DeMinds, or open a supported online view in the app. Disconnecting GitHub does not delete published files. On iOS 18 or later, where supported by the system, temporarily translate the preview, map titles, and Notes without changing the original. Core work in DeMinds needs no account. Documents, edits, and history are processed on your device or in your chosen Workspace, not on DeMinds servers. Web pages, remote documents, Content Sources, iCloud, translation, and publishing use the relevant network or system services when you enable those features. DeMinds Plus also adds the Original Mind Map, Presentation Playback, Workspace Backup import, and a higher project limit in Continue Working.
