ACH Next: Analysis of Competing Hypotheses
A desktop successor to PARC ACH 2.0.5. It reads the classic .ach format and adds three things:
- Every cell answers one defined question
- A weight-of-evidence score beside the classic inconsistency count
- A “Which evidence is decisive?” check that lists the evidence your leading hypothesis depends on
Alpha pre-release. An early version for trying out, not yet for operational use. Keep copies of files that matter to you, and tell us about anything that goes wrong.
Free software under the MIT licence. The builds are not code-signed, so Windows and macOS ask you to approve the first launch.
Install from a terminal
The script downloads the installer, checks its SHA-256 checksum and installs it, without the prompts below.
- macOS:
curl -fsSL https://thabor.cz/files/ach/install.sh | sh - Windows (PowerShell):
irm https://thabor.cz/files/ach/install.ps1 | iex
Opening an unsigned build
- Windows: if SmartScreen says “Windows protected your PC”, click More info, then Run anyway.
- macOS: open ACH Next once and click Done. Then open System Settings → Privacy & Security, click Open Anyway next to the ACH Next message and confirm with your password. You only need to do this once.
- Linux: on Debian or Ubuntu, run
sudo apt install ./ACH-Next_0.2.1_amd64.deb; on Fedora, runsudo dnf install ./ACH-Next-0.2.1-1.x86_64.rpm.
Offline, MSI and AppImage installers are available on request.
Uninstall
On Windows, use Settings → Apps. On macOS, drag ACH Next to the Trash. On Linux, remove the package with your package manager.
Upgrading from ACH 0.1.1: the terminal install removes the old version for you. If you install by hand, first remove the old ACH the same way.
