Downloads
H.E.L.E.N.A. ships in four tiers. Lite (free) and Elite download direct from this site at launch. Ultimate and Extreme subscribers download directly from this site too — signed builds, with checksums published next to every file. A Fab Marketplace listing comes later, as an option — never the only door.
Platform: Windows today — standalone, no Unreal Engine required, with the Unreal Engine 5 plugin there when you want her inside the engine. Standalone builds for Linux and macOS are on the roadmap.
Helena Lite — free standalone
Helena Lite runs on your own PC — no Unreal Engine needed and no account needed to start. She answers questions and explains documents in plain words. Her brain runs entirely on your machine; your files and conversations never leave your computer.
Windows 10/11 (64-bit). One installer from this page — download it, run it, done. No loose files to unzip or move.
No builds published yet. The free Lite download arrives here with the launch — direct from Harrison Interactive.
Ultimate & Extreme — direct download
No builds published yet. The first signed build hasn't shipped — when it does, it will appear here with its SHA-256 checksum, and we'll announce it on the news page.
Ultimate and Extreme are the subscription tiers on this site. Manage your subscription or sign in.

How updates work
Helena never reaches out on her own — there is no silent update check in the local product. Updates are builds you download yourself from this page. Every build is cryptographically signed with Harrison Interactive's offline key and hash-verified before anything is installed — a bad signature means the build is refused, no exceptions. You can always see the latest signed manifest at /api/helena-updates/manifest.
