What Fuse is
Fuse is a tool that sends your prompt to two third-party AI providers, compares their responses, and maps where they agree and disagree. It does not generate its own answers. It does not store your identity.
What we collect
- Your prompt text
- The model outputs and claim-level analysis produced by the run
- A randomly generated device ID stored in your browser (localStorage). This is not linked to your name, email, or any personal information.
- Basic run metadata: timestamp, model names, agreement and disagreement counts
We do not collect your name, email address, IP address, or any account information. There are no user accounts.
How it is stored
Run data is stored in Supabase (a third-party database provider). Each run is identified by a randomly generated UUID. Anyone who has the UUID link can view that run — there is no password protection on individual runs. Do not share run links if the content is sensitive.
Run history is limited to your last 10 runs per device and is tied to your device ID only.
Third-party AI providers
Your prompt is sent to the following providers to generate responses:
- OpenAI — subject to OpenAI's Privacy Policy
- Anthropic — subject to Anthropic's Privacy Policy
Fuse does not control how these providers handle your data. Do not enter confidential, sensitive, or personally identifiable information into Fuse.
Terms of use
- Fuse is provided as-is, without warranty of any kind.
- Do not use Fuse to process confidential, legally privileged, or personally identifiable information.
- Do not use Fuse for any unlawful purpose.
- We reserve the right to change or discontinue the service at any time.
Changes
We may update this page as the product evolves. The date at the top reflects the most recent revision. Continued use of Fuse after changes constitutes acceptance.
