# Sortana
|
||
|
||
Sortana is an experimental Thunderbird add-on that integrates an AI-powered filter rule.
|
||
It allows you to classify email messages by sending their contents to a configurable
|
||
HTTP endpoint. The endpoint should respond with JSON indicating whether the
|
||
message meets a specified criterion.
|
||
|
||
## Features
|
||
|
||
- **AI classification rule** – adds the "AI classification" term with
|
||
`matches` and `doesn't match` operators.
|
||
- **Configurable endpoint** – set the classification service URL on the options page.
|
||
- **Prompt templates** – choose between several model formats or provide your own custom template.
|
||
- **Custom system prompts** – tailor the instructions sent to the model for more precise results.
|
||
- **Filter editor integration** – patches Thunderbird's filter editor to accept
|
||
text criteria for AI classification.
|
||
- **Persistent result caching** – classification results are saved to disk so messages aren't re-evaluated across restarts.
|
||
- **Advanced parameters** – tune generation settings like temperature, top‑p and more from the options page.
|
||
- **Debug logging** – optional colorized logs help troubleshoot interactions with the AI service.
|
||
- **Packaging script** – `build-xpi.ps1` builds an XPI ready for installation.
|
||
|
||
## Architecture Overview
|
||
|
||
The extension relies on both WebExtension scripts and Thunderbird's experiment
|
||
APIs:
|
||
|
||
- `background.js` loads the saved endpoint, registers the UI patching script,
|
||
and listens for test messages.
|
||
- `experiment/api.js` exposes the `aiFilter` namespace. It loads
|
||
`modules/ExpressionSearchFilter.jsm` which implements the custom filter term
|
||
and performs the HTTP request.
|
||
- `experiment/DomContentScript/` registers content scripts for Thunderbird
|
||
windows; `content/filterEditor.js` modifies the filter editor UI.
|
||
- `options/` contains the HTML and JavaScript for the options page.
|
||
- `_locales/` holds localized strings used throughout the UI.
|
||
|
||
### Key Files
|
||
|
||
| Path | Purpose |
|
||
| --------------------------------------- | ---------------------------------------------- |
|
||
| `manifest.json` | Extension manifest and entry points. |
|
||
| `background.js` | Startup tasks and message handling. |
|
||
| `modules/ExpressionSearchFilter.jsm` | Custom filter term and AI request logic. |
|
||
| `experiment/api.js` | Bridges WebExtension code with privileged APIs.|
|
||
| `content/filterEditor.js` | Patches the filter editor interface. |
|
||
| `options/options.html` and `options.js` | Endpoint configuration UI. |
|
||
| `logger.js` and `modules/logger.jsm` | Colorized logging with optional debug mode. |
|
||
|
||
## Building
|
||
|
||
1. Ensure PowerShell is available (for Windows) or adapt the script for other
|
||
environments.
|
||
2. Run `powershell ./build-xpi.ps1` from the repository root. The script reads
|
||
the version from `manifest.json` and creates an XPI in the `release` folder.
|
||
3. Install the generated XPI in Thunderbird via the Add-ons Manager. During
|
||
development you can also load the directory as a temporary add-on.
|
||
|
||
## Usage
|
||
|
||
1. Open the add-on's options and set the URL of your classification service.
|
||
2. Create or edit a filter in Thunderbird and choose the **AI classification**
|
||
term. Enter the desired criterion (for example, a short description of the
|
||
messages you want to match).
|
||
3. When the filter runs, the add-on sends the message text to the service and
|
||
checks the JSON response for a match.

## Acknowledgments
|

|

Sortana builds upon knowledge gained from open-source projects. In particular,
|
||
[FiltaQuilla](https://github.com/RealRaven2000/FiltaQuilla) and
|
||
[Expression-Search-NG](https://github.com/opto/expression-search-NG) clarified
|
||
how Thunderbird's WebExtension and experiment APIs can be extended. Their code
|
||
provided invaluable guidance during development.
