Frequently Asked Questions

Answers to common questions about Human Signal Index: what it is, how it differs from other tools, trust, contributions, commercial use, and the beta.

Common questions about how HSI works and how to use it.

What is HSI?

A public-source intelligence and trust analysis platform. It helps people collect, verify, investigate, forecast, and publish open-source findings with evidence trails.

How is HSI different from ChatGPT?

HSI is not a chatbot and does not generate conclusions. It organizes real sources and evidence, and people review findings before publication.

How is HSI different from social media?

HSI is a research and review environment, not a feed. The focus is provenance and evidence, not engagement.

How is HSI different from traditional OSINT tools?

HSI adds a review workflow, an evidence graph that records relationships, forecast accountability, and transparent corrections.

How does trust work?

Trust is a recorded, explainable measure of a source’s reliability over time. It is not a hidden score and not a claim that any single item is true.

Can I submit sources?

Yes. Signed-in users can submit a source or signal for review; submissions enter a review queue.

Can I contribute?

Contribution is expanding through roles and the beta program. A broader public contributor role is planned.

Can I use HSI commercially?

Organizations can request a demo to discuss access. Commercial terms are handled case by case.

How are corrections handled?

Corrections are recorded openly and linked to the affected publication rather than edited quietly.

How are forecasts evaluated?

Forecasts are recorded with a resolution date and scored against outcomes so accuracy and calibration can be measured.

How is transparency maintained?

Sources, evidence, corrections, and forecast outcomes are made visible so the work can be checked.

Can organizations request demos?

Yes. Use the demo request page to schedule a walkthrough.

Can developers access APIs?

Yes — a set of read-only, public-safe API endpoints is available today (platform intelligence, trust, transparency, and the marketplace). A fuller authenticated API with API keys and SDKs is planned. See the API page for endpoints and rate limits.

How does the beta work?

Apply through the beta page. Applications are reviewed in batches and testers are onboarded by email.
