Discussed the authentication architecture for the new API. Team agreed to move forward with OpenIddict instead of Auth0 for better control over token issuance.
The Format That Matters
The format you write in determines how well AI can work with your ideas.
LLMs were trained on markdown. Headers, bullets, and code blocks aren't just formatting — they're signals that help AI understand, summarize, and reason about your content with far more precision than plain prose or rich-text formats.
Paste a .md file into Claude Projects, drop it into Cursor, feed it to a custom GPT, or serve it via MCP. No conversion, no reformatting. Your notes are already in the right format for any AI workflow.
Plain text survives every platform shift. No export anxiety, no proprietary format, no lock-in. Your notes work in any editor — Obsidian, VS Code, GitHub, or a terminal — today and twenty years from now.
Features
A focused set of tools that keep your notes structured, portable, and ready to use in any AI workflow.
Write in a beautiful rich editor and get clean, portable .md output every time. No lock-in, no proprietary formats — just text.
Your notes are automatically saved to the cloud and accessible from any device. Work locally or in the cloud — the choice is always yours.
Capture thoughts out loud with the built-in recorder. Save audio alongside your notes locally or to the cloud for future reference or transcription.
Turn any line into a checkbox with a single keystroke. Track progress inline without leaving your document or switching to a separate task app.
Standard markdown is the universal language of AI. Your notes are structured so any LLM can read, summarize, and reason over them immediately.
A carefully tuned visual system that looks great in any lighting. Switch themes without leaving your flow — your eyes will thank you.
Record your thoughts out loud and get a structured markdown note automatically. AI converts your audio into clean, organized text — ready to edit, search, and reference alongside your other notes.
Instantly distill long notes into crisp summaries. Automatically extract key people, topics, and action items from any document — turning your raw notes into structured, queryable knowledge.
Connect your marqup knowledge base directly to Claude, ChatGPT, and other AI tools as a live context source. Your notes become the memory your AI never had — surfaced exactly when you need it.
Discover connections across your entire knowledge base as you write. Surface similar notes, recurring themes, and linked ideas automatically — without manually building a graph or tagging everything yourself.
How It Works
No steep learning curve. No configuration rabbit holes. Just open it and write.
Start a new document in one click, or open an existing .md file from your device or the cloud.
Use the rich editor to format as you go. Headings, bold, code, tasks — the toolbar keeps you moving without breaking your train of thought.
Save locally for full control or sync to the cloud. Your file is always clean, portable markdown — paste it into Claude, drop it in Cursor, or serve it via MCP without any conversion.
