How to Use SynthID Detector
The public SynthID Detector lives at synthid.com. This page is an independent walkthrough so you can check media correctly, read results carefully, and know when a daily quota becomes a bottleneck.
Before you start
- Prefer the original or least-compressed file you have.
- Remember: no SynthID ≠ proof of human authorship. See What is SynthID?
- Accounts are typically limited to about 10 checks per day after login (confirm on the official UI; limits can change).
Step-by-step
-
Sign in at synthid.com
Open https://synthid.com and sign in with Google, OpenAI, or Apple — whichever options the official site currently offers.
-
Upload your media
Submit the image, video, or audio file you want to verify. Follow on-screen format guidance. Avoid unnecessary re-exports before checking.
-
Read the result
Note whether SynthID was detected, not detected, or inconclusive. Save a screenshot or export notes if you need an editorial or brand audit trail.
How to read common outcomes
| Result | Practical meaning |
|---|---|
| Detected | File appears to carry a SynthID watermark from a supported system. Still verify context before publishing strong claims. |
| Not detected | No SynthID found. Does not prove human-made content. |
| Unclear | Needs more context — provenance, source questions, other signals. |
When the daily limit gets in the way
Spot checks are free on the official tool. Newsrooms, brand reviews, and agencies often need more than ~10 files in a day, plus a structured report. That is the gap our optional Batch Report ($9.99) and Quick Guide ($4.99) address — workflow and documentation help, not a fake local clone of Google’s engine.
Payments may still be email-order until Stripe is live: upgrow.us@gmail.com.
Run a free check now on the official detector, then come back here if you need batch documentation.
