FAQ
Quick answers to the most common questions about plans, API keys and how the platform works.
Do I need API keys to use OSINT UI?
No. The three Free-plan tools work with no key at all. On PRO, most tools also work without keys using public sources, but they return noticeably more results if you connect your own — free on most providers. See API keys (BYOK).
Is there a free trial?
No. Every paid plan is charged directly from the first click. The Free plan (no card, forever) is how you try the platform before deciding.
Can I cancel anytime?
Yes, from Settings → Manage subscription. Cancelling stops future charges and you keep access until the end of the period you already paid for — no commitment, no penalty.
What's the difference between PRO and PRO+?
PRO+ adds the REST API and the MCP server with a 5× higher rate limit. If you're not automating queries or connecting an AI client, PRO is enough. See Plans & pricing.
Does Investigation Graph replace the other tools?
No — it uses them. Investigation Graph automatically fires the other tools' probes against the same target and correlates the result into a graph; every tool still exists on its own too, for a quick standalone lookup.
Are results saved automatically?
No. Only what you explicitly archive to Saved Investigations is kept. See Security & privacy.
Can I use the platform from multiple devices?
Yes, up to 2 devices per individual PRO account. If your team needs more people, the right plan is Teams, where every analyst gets their own account.
What happens if my payment fails?
You get an email with a link to update your payment method. If it's still unresolved after the grace period, the account drops back to Free — your data and saved investigations aren't lost because of this.
Where do I report an issue or ask for help?
Through the built-in support inside the app, or by writing to osint-ui@proton.me.
