twriter Nightshift

Nightshift

The build train that ships twriter: signed, notarised, and updated in place.

Before the first release

The beta list gets twriter first.

twriter is being packaged for its first release, so there is no download on this page yet. It will be free on macOS and Windows: your manuscript and your canon in one place, with a linter that catches the moment chapter 15 contradicts chapter 3. Join the beta list and you will hear the day there is a build to install.

The rest of this page is written for that day: what twriter needs from your machine, what the first launch looks like on each platform, and how to check a download against its published checksum.

Beta

Test it before it ships.

The next milestone is five writers using it on a real manuscript. One email when there's a build to install. Nothing else, ever.

Stored on twriter.sh. No third-party form, no tracker, no list rental.

All builds

Every platform, every architecture.

No builds published yet.

When the first release ships, every build appears here with its size and its checksum.

The first time you open it

Here is exactly what each platform will show you the first time you run it.

macOS

Signed · notarised

twriter is signed with an Apple Developer ID and notarised by Apple.

Windows

Unsigned

The Windows build is not signed with an Authenticode certificate, so SmartScreen will show a “Windows protected your PC” warning before it will run. Choose More info → Run anyway.

Verify your download

Every build's SHA-512 is listed in the table above. Checksums are published as base64, matching the update feed exactly.

The obvious command is the wrong one: shasum -a 512 prints hex and will never match. Use the two-stage pipe.

Shell 
openssl dgst -sha512 -binary twriter-<version>-<arch>.dmg | openssl base64 -A

Shown for reference. There is no published file to check yet. The filename will follow this shape.

System requirements

macOS
macOS 11 Big Sur or later. Apple Silicon and Intel builds provided.
Windows
Windows 10 or later, 64-bit.

Updates

twriter checks for updates when it starts, downloads them in the background, and installs them the next time it opens. Updates come from twriter.sh, not an app store.
