For Claude, Gemini, Copilot Studio and compatible Skills
A single portable SKILL.md plus an offline reference copy of the Trust Check method.
Some AI accounts may not offer custom Skill imports. You can still use the original Markdown.
Optional AI fairing · Original app preserved
Take Trust Check into your own AI
Aletheia Trust Check already works as a free browser app. This optional Skill lets compatible AI tools follow its source-checking method inside their own chat or agent interface.

Choose your package
For ChatGPT / Codex plugins
The same Skill wrapped in a portable plugin.json package. No paid API or MCP server is bundled.
This is a package to import in a supported plugin environment, not an installed or publicly listed ChatGPT plugin.
Three easy steps
- Download the ZIP that matches your AI.
- Import it using your AI's Skill or plugin controls, where supported. If your AI cannot import Skills, use the ordinary Trust Check Markdown instead.
- Ask normally: “Can I trust this company?” or “Check the claims in this post.”
The Skill does not give an AI web access or permission to act. It must say when information could not be checked. A missing search result is not proof that something is false.
Need platform-specific instructions?
Claude and Gemini
Use your AI's custom Skill import feature if your account supports it. Upload the Skill ZIP, which contains the instruction file and reference material. Availability and menu labels depend on your account.
Microsoft Copilot
In an eligible Copilot Studio agent, add an existing Skill and upload the Skill ZIP. Microsoft 365 Copilot Agent Builder preview also accepts a ZIP. This is not automatically available in ordinary free Copilot chat.
ChatGPT and Codex
Use the Plugin ZIP with a supported local/personal plugin marketplace or plugin-creation workflow. A public listing requires separate submission and approval.
DeepSeek, Odysseus and other AI tools
If your particular AI environment supports SKILL.md imports, use the Skill ZIP or extract its files. Otherwise open the original Trust Check Markdown in the AI. Ordinary chat and developer agent environments are not necessarily the same product.
One Aletheia app, many doors
These packages contain the existing Trust Check v0.5.1 as a version-pinned reference. The original browser app and its canonical Markdown remain the source of truth. Updates to the original method must be reviewed before rebuilding the packages.
Publication status: Aletheia-hosted download packages and documentation. Static file-format checks passed. Importing and running this Skill inside external AI provider accounts has not yet been independently verified.
