About nenspace

nenspace is a productivity application that combines working memory, tasks, notes, habits, and a logbook into a single space. It runs on custom fine-tuned language models and launched this week on web and iOS. The product positions itself as an "extended mind, not a second brain," with a free tier to start.

Review

nenspace enters a crowded productivity space with a different premise. Most note-taking apps store information and most LLM chatbots respond to queries; nenspace tries to fuse the two into one workflow. The core idea is that your working memory holds about four things, and the app captures the rest until you have time to sift through it. I tested the flow between model responses and the space side to see how the pieces actually connect.

Key Features

• nen-1, nen-2, and nen-alia - a family of fine-tuned models trained to be concise and question assumptions rather than being padded and flattering like frontier models that use RLHF
• Working memory capture - catches thoughts at any time; a "sift" action then proposes a destination (task, note, habit, space, or "later") for each captured item, and nothing moves without explicit approval
• Integrated model queries - you can query nen-1 about your notes or search the web from within notes pages and the logbook without changing screens
• Composer (⌘+K) - a command palette that opens discussion with the nen models from any page
• Four core spaces - tasks, notes, logbook, and habits live in one backend rather than across separate apps

Pricing and Value

The product is free to start and includes a paid tier called Nen Pro. The maker notes a one-month free trial of Nen Pro is available, with a reminder email five days before billing begins. Specific pricing numbers for Nen Pro are not yet listed on the launch page. The value argument rests on consolidating several productivity functions into one app rather than subscribing to separate task, note, and journaling services.

Pros

• Models answer with pushback on bad ideas rather than defaulting to agreement.
• Captured items stay in a working-memory buffer until you choose to sift them, so nothing becomes a formal task prematurely.
• Search and model queries work inline from notes and logbook pages.
• Postgres, auth, and storage run on one Supabase backend instead of three disconnected vendors.
• Everything survives a wrong sift decision - nothing moves without approval and all items are recoverable.

Cons

• One launch comment reports an 8-digit sign-up code fails to log in; the maker says it was fixed, but this suggests the auth flow needs attention for new users.
• nenspace launched this week, so long-term stability and the roadmap for roadmap items or features are not yet demonstrated.
• For teams that need shared workspaces, multiple users, or collaborative editing, there is no indication such support exists. This tool suits individual users, not group or enterprise environments.

In my assessment, nenspace works best for solo users who want a private place to capture daily thinking, then have an AI model that argues back instead of agreeing. The sift workflow is the differentiator: boring, deliberate, and functional. If you want something that decides for you, or you need to cooperate with others in real time, this is not the right fit. Try the free tier first and check whether the models' assumptions questioning matches your own style before paying for Pro.
