AI's Lofi: alternative models for the minority, trained to answer, not agree. A space for notes, tasks, habits and a logbook alongside the model. the model • nen is trained by nenspace to answer, not to agree, concise where others pad, plain where others flatter, quiet when nothing needs saying. • a model that always agrees is lying to someone • web search when a question needs it, with the sources it read. images and files can be attached • ask nen on any page of the space, about a note, a logbook entry or a task list • group chats into nen spaces to keep a piece of work together the space • today · memory · calendar · notes · logbook · habits, in one room next to the model • a good answer with nowhere to land scrolls away • the space is where it lands: a note, a task, a habit, a line in the logbook • choose what belongs in the room, every tile can be shown or hidden the capture • a thought arrives at the wrong moment: walking, cooking, mid-task. memory catches it in five seconds • thoughts can sit before they are turned into anything. not everything needs to become a task straight away the sift • sift reads the pile in memory and proposes a home for each thought: a task for today, a note, a habit, a project, or simply set it down • it notices what keeps coming back, nothing moves without an ok, everything is recoverable the price • capture is free forever. all of nenspace is $13 a month or $129 a year, about a third of the usual stack of a chatbot, a notes app, a task app and a habit tracker.

You read a hundred things a month and remember almost none of them. Not because you weren't paying attention, but because nothing was keeping the thread. Mneme remembers it. Send it a link, a video, a PDF, or a half-formed thought. It reads it, sets it beside everything you already think, and tells you when the two argue. A MAP THAT DRAWS ITSELF Everything you save lands on a map, near the ideas it already belongs with. You don't file anything, tag anything, or maintain anything. Topics form on their own and drift as you change. Zoom into one and it opens as a smaller map of its own. IT NOTICES WHEN YOU CONTRADICT YOURSELF Most apps store what you save. Mneme reads it. When something you saved this week disagrees with something you believed last month, it tells you — and shows you exactly where the two split. It also tells you when a thread is picking up speed, when different roads arrive at the same place, and when something you cared about has gone quiet. FIVE WAYS IN Atlas: the map. Every capture, placed by meaning. Mind: what's moving. Threads, tensions, convergences, dormant ground. Archive: the plain list, for when you just want to find the thing. Pulse: a check-in on what the people you follow have been engaging with. You: the long view. Your streaks, your busiest hours, and dozens of other insights. CAPTURE FROM ANYWHERE Share sheet, camera roll, or your own voice. Articles, YouTube, TikTok, Instagram, PDFs, screenshots, book pages, quotes, and thoughts you haven't finished having yet. Most captures land in a few seconds. Bring your history with you: import your existing links, or connect Letterboxd and Goodreads so what you watch and read shows up on its own. IT COMES BACK TO YOU Mneme surfaces one thing a day worth thinking about again — a contradiction that formed while you weren't looking, a thread gathering pace, something you saved a month ago and forgot. No unread counts. No pile. Nothing to clear. Mneme is free with ads and monthly capture limits. Mneme Plus ($2.99/month) removes ads and raises the limits. Subscriptions renew monthly and can be canceled anytime. 'Mneme' was one of the three original muses, before there were nine. Melete for practice, Aoide for song, and Mneme for memory. This one is for Mneme. Terms of Use: https://mneme-app.com/terms.html

Verdict
The clearest difference is ads: nenspace at none against Mneme's shown. Mneme's advantage is update cadence (every 10 days vs every 3 months) and ratings volume (6 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. nenspace sells 2 in-app purchases, starting at $9.99 per month and Mneme sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for nenspace against 5.0 for Mneme. That said, the two scores are not equally well evidenced: Mneme has 6 ratings behind it against 1, so its average is the more settled of the two.
nenspace ships an update every 3 months, Mneme every 10 days. Both last shipped on October 31, 2026.
