Hjarni Notes vs DotSpark Intelligence

Your AI starts from zero every conversation. Hjarni fixes that. 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 an official MCP server. Notes, folders, tags. That is the whole product. MCP is not a plugin bolted on afterwards. The app was built around 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. 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 BRAIN, 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, 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. SHARE A BRAIN WITH 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 ON PURPOSE We left features out on purpose. 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.

Your human edge is how your thinking connects. Everyone now has the same AI. The same answers, the same frameworks, the same confident average. When everyone thinks with the same tools, the edge moves to the one thing AI can't hand out: your own intelligence. And intelligence isn't a pile of thoughts. It's how your thoughts connect. DotSpark Intelligence is built on connected thinking. Every insight you capture is linked to what you already know, so isolated ideas become patterns, patterns become understanding, and understanding becomes an edge that is entirely yours. CAPTURE DOTS A dot is a thought worth keeping: an insight, a lesson, a conclusion you reached. Type it, say it, or save it straight from ChatGPT or Claude with one phrase: "Save that to DotSpark." THINK ON PAPER Some of your best thinking happens with a pen. Write with the MOAT Pen and your handwritten notes flow in as dots, ready to connect with everything else you think. CONNECTIONS FORM ON THEIR OWN This is where DotSpark is different. As your dots grow, it connects them across days, topics and sources. Sparks reveal what you couldn't see one thought at a time: ideas that keep returning, threads you didn't know you were following, conclusions that only make sense together. KNOW YOUR THINKING IDENTITY Connected thinking shows how you actually think. Your Cognitive Identity reveals what you're learning, where you're growing, and what makes your judgment distinctly yours rather than something that arrived pre-formed from a model. ASK YOUR OWN INTELLIGENCE Question what you've built. Answers draw on your connected dots and sparks, not the internet's average. YOUR EDGE, COMPOUNDING A single thought fades. Connected thoughts compound. Every dot strengthens the web, and over weeks and months it grows into something no tool can copy: a clear, living map of how you think and who you're becoming as a thinker. BUILT FOR Professionals and leaders who use AI every day and want to stay the author of their own thinking. Not a note-taking app that stores thoughts. Not a journal that holds them. An intelligence that connects them. YOURS Your intelligence is for you. Delete your account and all of your data at any time, right inside the app. DotSpark Intelligence. Your human edge, powered by connected thinking.
