Zeno

Zeno is a local AI workspace from Icosa Computing for people who want to work with documents and code on their own Mac. Icosa lists its launch as August 19, 2026. Unlike a model manager that asks you to select and configure a model, Zeno packages the model with a workspace for everyday tasks.

Features and requirements

The official product page describes file reading, document drafting and editing, and longer agent tasks. It includes a 35B-parameter model and advertises offline operation without token charges. These are vendor descriptions, not results from our own performance or privacy testing.

As checked on September 28, 2026, the download requires an Apple Silicon Mac with at least 16 GB of RAM. The installer is approximately 18 GB; Icosa asks for about 45 GB of free space during setup and 25 GB afterward. Plan for that download before trying it on a constrained laptop.

Who should try it?

Zeno is a candidate for writers organizing source documents, developers reviewing a small project, or people who need an assistant while offline. Its appeal is the integrated local workspace. The useful question is whether it handles your actual documents accurately, rather than whether a model parameter count looks impressive.

A first workflow

Download from Icosa and confirm your Mac meets the requirements.
Create a test folder containing copies of two or three non-sensitive documents.
Ask Zeno to summarize their differences and identify the source for each conclusion.
Request a short draft based only on those documents, then compare it with the originals.
Review edits before using the output, and test offline behavior if that is central to your workflow.

Keep this first task small. Track incorrect statements, missed information, and the time required to review the result. That gives you a more useful adoption decision than an isolated generation-speed figure.

Pricing and limitations

Icosa currently presents Zeno as free with no per-token charge. Hardware, storage, electricity, and your review time remain real costs. Local execution does not ensure that generated claims or file edits are correct. The product page itself notes that the app is early and may feel slow; memory pressure and other running applications can affect the experience.

This listing does not assert an open-source license for the desktop app. Check the terms and current download requirements before adopting it for a team.

FAQ

Does it work on Windows or an Intel Mac?

The checked download page specifies Apple Silicon macOS. Do not assume other platforms are supported.

Can it work without an internet connection?

Icosa says the bundled model supports offline use. The initial download and optional updates require a connection.
