Evernote wants to remember everything. Who pays for forever?
The green elephant built a business around the things we forget. Its second act asks a less romantic question: how much is a lifetime of notes worth?
Reflect Put Your Notes Back in Your Hands
The calm note app has made a noisy bet: local Markdown, open source code and your own AI keys. Here is who should move, who should wait, and why Reflect still feels unusually good to write in.
Your Notes Have Been Asking for Better Plumbing
Capacities turns the shoebox of digital notes into a cast of people, books, meetings and ideas. The catch is deliciously specific: it works best when you are willing to stop thinking in folders.
Martin Schneider
Martin Schneider is the co-founder and CEO of RemNote, the all-in-one note-taking and spaced-repetition app he started coding as an MIT computer science student in 2017 to fix his own habit of forgetting everything he learned a semester later. What began as a private side project he used alone for three years grew into a learning platform with over a million users, backed by a $2.8M seed round from General Catalyst, 468 Capital, Soma Capital and Dorm Room Fund. He blends learning science, neuroscience and software to chase a single idea: that you should be able to learn something once and remember it forever.
Tana
Tana is an AI-native workspace that turns messy notes, meetings and voice memos into structured, queryable knowledge. Its signature feature, Supertags, lets any bullet point become a database record with defined fields, so notes double as a living knowledge graph that AI agents can read, summarize and act on. Founded in 2021 by ex-Googlers and productivity builders and based in Palo Alto with an engineering hub in Oslo, Tana raised a $14M Series A in February 2025 (led by Tola Capital), reaching $25M total funding after emerging from a stealth beta with a 160,000+ person waitlist.
