Studio-Quality Complex Compositions
Gemini 3 Pro Image can build detailed scenes and sophisticated layouts with greater precision. A polished composition may justify a closer review, but it is not proof of AI generation.

Review High-Fidelity Gemini 3 Pro Images
Gemini 3 Pro Image, also known as Nano Banana Pro, generates high-fidelity designs, infographics, and multilingual text. Our tool reviews these suspected outputs using multiple visual signals. These polished visual qualities provide helpful context rather than absolute proof of AI generation.
Check Nano Banana Pro Images Accurately
Gemini 3.1 Flash Image, known as Nano Banana 2, produces fast edits with sharp detail, localized text, and consistent subjects. This Gemini AI image detector reviews suspected outputs for visual and file-level clues without claiming exact source attribution.
Review Watermark and Provenance Clues of Nano Banana 2 Generated Images
This tool functions as a practical nano banana watermark detector by combining AI probability with visible watermark cues and standard metadata. While we do not decode private SynthID systems, we analyze available provenance information. Heavy cropping or compression may reduce detection confidence.
How to Check Nano Banana Pro or Nano Banana 2 Images
Step 1. Paste or Upload Image
Paste a copied image directly into the detection box. Alternatively, upload a supported image file from your device to begin the review process.
Step 2. Click Detect AI
Click the detection button to initiate the scan. The tool analyzes the file for AI-generation and editing signals relevant to suspected Nano Banana Pro or Nano Banana 2 images.
Step 3. Review the Report
Read the probability percentages and review any highlighted visual clues. Use these insights to make a final, informed decision about the image.
Common Signals in Nano Banana Pro & Nano Banana 2 Images
Nano Banana Pro is built for polished, information-rich visual creation. These capabilities help reviewers understand the kinds of images Gemini 3 Pro Image can produce, but no single characteristic proves an image's origin.
Accurate Multilingual Text
Nano Banana Pro is designed to render clearer text across languages for posters, mockups, and branded graphics. Readable text alone does not identify the source model.
Context-Rich Infographics and Diagrams
Its reasoning and world knowledge support educational explainers, diagrams, and data-rich visuals. Review the full image and its provenance rather than relying on subject matter alone.
Precise Localized Editing
Creators can refine selected areas, change individual elements, or transform part of an existing image. Subtle local edits can make source checks more important.
Camera, Lighting, and Color Controls
Nano Banana Pro can adjust camera angles, focus, scene lighting, and color grading. These controlled visual choices are capabilities, not unique detection fingerprints.
2K and 4K Production Output
The model supports flexible aspect ratios and high-resolution output for social, web, and print use. Resolution does not determine whether an image is human-made or AI-generated.
Why Use This Nano Banana Detector
Clear AI Probability
View a clear breakdown of AI, mixed, and human probability. The report helps you assess a suspected Gemini image without overstating certainty.
Basic or Advanced Scan
Use Basic Scan for a fast probability check. Choose Advanced Scan when a higher-stakes image needs a deeper forensic breakdown and a more detailed report.
Downloadable Review Report
The Advanced Scan can generate a downloadable PDF report. This includes a verification fingerprint for a more traceable and documented review process.
A Practical Next Step
Take a practical next step in your workflow by using our results to confidently accept the image, investigate further, or request source files.
Free Without an Account
Run a Basic Scan online for free without creating an account or installing software. Move to Advanced Scan when you need deeper review evidence.
Simple Image Uploads
Paste a copied image or upload a standard JPG, JPEG, PNG, or WebP file. Run one focused check instantly without dealing with complex settings.
Honest Confidence Limits
We provide honest confidence limits by presenting results as probability signals rather than definitive proof, openly acknowledging the potential for false positives.
Private Image Review
Your uploaded images are processed securely for the scan. Your files are never stored or used to train any AI models.

Nano Banana Pro & Nano Banana 2 Detector FAQs
Find answers about detecting Gemini images, watermarks, and verification limits below.
A Gemini AI image detector analyzes visual files to identify probability signals, metadata clues, and visual artifacts. It helps reviewers evaluate whether an image was likely generated or edited using Google's Gemini models, which adds context for approval decisions without serving as absolute proof.
Nano Banana Pro is the familiar name for Gemini 3 Pro Image. Google designed it for studio-quality generation and editing, including complex compositions, multilingual text, infographics, precise local edits, creative controls, and high-resolution output.
Nano Banana 2 is the familiar name for Gemini 3.1 Flash Image. It brings advanced image generation and editing to a faster workflow, with improved text rendering, localization, world knowledge, subject consistency, and production-ready output.
Lynote combines AI probability with visual, watermark, metadata, and available provenance clues when reviewing a suspected Gemini 3 Pro Image output. The result can support a closer review, but it cannot prove that Nano Banana Pro was the exact source.
Lynote reviews suspected Gemini 3.1 Flash Image outputs using the same combination of probability, visual, watermark, metadata, and provenance clues. It cannot prove the exact source model or reliably distinguish version 2 from Pro.
No, third-party tools cannot guarantee decoding of Google's invisible SynthID watermark. The detector relies on visible watermarks, metadata, and visual artifacts instead.
Yes, but cropping, resizing, or applying heavy filters can reduce the detection confidence and remove crucial metadata clues.
You can upload JPG, JPEG, PNG, and WebP files up to 10MB. For the clearest review, use the highest-quality version available rather than a heavily compressed copy.
Yes, you can use the basic Gemini AI image detector online for free without needing to sign up or create an account.
Accuracy varies with image quality, editing, compression, available metadata, and source context. False positives and false negatives can occur, so use the result as one review signal rather than absolute proof of origin.
Uploaded files are handled for the scan, are not used to train AI models or shared with third parties, and are removed after processing according to Lynote's privacy workflow.
No. High-fidelity compositions, readable multilingual text, infographics, precise edits, and controlled lighting can also come from other tools or human workflows. These characteristics provide context, not proof of origin.
