Lately, I’ve been giving my notes an AI copilot.
I’ve worked on trading screens, payment flows and the APIs behind them. Knowtis is my current project: an editor for exploring a topic with AI, writing about it and turning your notes into flashcards and quizzes.
A workspace for writing and learning, with AI tools built into a rich-text editor. Explore a topic, create notes and turn them into study material. The copilot can search your notes and the web, then propose changes for you to review.
Use your own OpenAI, Anthropic, Google or OpenRouter API key with the copilot. Available with a registered account.
Generate flashcards, quizzes, summaries and mind maps. Review flashcards with spaced repetition.
Rich text, code blocks, slash commands and inline AI. Write together, with edits you can review before saving.
I’ve worked on trading screens, payments and corporate spending tools. Most of that work sits between the interface, the API and the data behind it.
At Efex I build the financial APIs and the MCP server that lets an AI assistant query them, plus the payment netting that replaced a treasury process people were running by hand. Knowtis is where I work on retrieval, collaborative editing and agent design outside my day job.
Experience on LinkedInAgent loops with tool use and an approval gate, retrieval over notes and documents, MCP tools, and the evals that catch regressions before a release.
