About afternote
Afternote is a note app for people who write notes constantly — meetings, 1:1s, decisions, follow-ups — and need to find them again months later. You write in plain text; the app organizes automatically; you ask questions in plain English and get answers cited from your own notes.
Day job: Systems Engineer at Endor Labs, where I build large-scale code-analysis systems used to find vulnerabilities in open-source software. Before that, 5+ years as Principal Architect at Virsec Systems — runtime protection software for industrial control systems, and a 20-person engineering team.
I’m an engineer, not a productivity guru or workflow consultant. My PhD work focused on detecting malware by analyzing low-level program behavior at scale — essentially, separating real signal from noise across millions of programs (98.45% accuracy, 1% false positives). Afternote applies that same lens to a different problem: messy daily notes that pile up faster than you can organize them.
I built afternote because I take notes constantly at work and every system I’d tried (Notion, Apple Notes, paper) eventually broke the same way: I could write fast, but I could never find the right note six months later when it mattered. Afternote is the answer I wanted for that problem. You write; the app organizes; you ask questions later.
What I’m not: a productivity consultant, an AI ethicist, or your manager. Afternote is one engineer’s take on what a simple, AI-helped notes app should be. Your privacy and data ownership are non-negotiable — see the privacy and terms pages for specifics. Workflow advice from me is just one opinion; trust your own.
How afternote works
Afternote uses large language models in three places:
- When you write a note — afternote summarizes the note’s intent and suggests a notebook. Runs once per save, costs fractions of a cent.
- When you chat — afternote retrieves relevant notes by semantic search and answers your question from them, citing the source note inline.
- When you attach an image — afternote extracts the text via OCR so it’s searchable later.
What afternote never does: train on your notes (guaranteed by the API terms of every model provider we use); power features for other users; sell or share your data outside your account. When you delete a note, it’s removed from the database immediately, embeddings included.
