Verified data from iNaturalist are shared with the Global Biodiversity Information Facility (GBIF), supporting international research and biodiversity studies.
Taxonomic Database
iNaturalist maintains a structured taxonomy, integrating scientific names and common names for better user understanding and classification.
Multilingual Support
The platform is available in multiple languages, making it accessible to users around the globe and encouraging broader participation.
Integration with Seek by iNaturalist
Seek is a child-friendly app powered by iNaturalist’s data that encourages learning about local species without needing an account or uploading data.
How It Works
iNaturalist functions through a combination of artificial intelligence, community engagement, and scientific data validation.
When a user encounters an interesting plant or animal, they can open the iNaturalist app or website and upload a photo of the organism. The app’s AI then processes the image using a deep learning model trained on millions of previously identified observations. It provides several suggestions, ranked by confidence level, for the species or taxonomic group the organism likely belongs to.
After the initial AI identification, the observation is shared with the iNaturalist community. Other users can confirm or suggest alternate identifications. Once multiple users agree on a species ID, the observation is marked as “Research Grade,” which means it has met scientific quality standards and is automatically shared with global biodiversity databases like GBIF.
This dual-validation approach—AI plus community—ensures both speed and accuracy. Users can also interact with the community by asking questions, commenting on observations, and participating in species identification challenges and bioblitz events.
The platform is also educational, with tools to view species guides, explore biodiversity hotspots, and understand ecological relationships between organisms.

Drawbacks
Accuracy Depends on Photo Quality
Blurry or incomplete images may lead to incorrect AI suggestions or prevent species confirmation.
Requires Internet for Full Functionality
Although offline observations are supported, identification and community features require a stable internet connection.
Limited for Microscopic Species
The platform is less effective for microscopic organisms or species that require lab-based analysis for accurate ID.
Not a Field Guide Replacement
While powerful, iNaturalist does not replace a full field guide or expert consultation for highly detailed taxonomy or ecological data.
Dependent on Community
For less common species, identification can take longer or remain unverified due to lack of experts in certain regions.
Comparison with Other Tools
Compared to other nature identification apps like PlantSnap, PictureThis, or Google Lens, iNaturalist stands out for its combination of AI and community-based verification. Where other apps rely solely on machine learning, iNaturalist enhances its accuracy by integrating feedback from human users and experts.
Unlike Seek, which is designed for private, educational use and does not share data, iNaturalist contributes to real scientific research by linking with biodiversity databases like GBIF. Compared to PlantNet, which is plant-specific, iNaturalist supports identification for all taxa—animals, fungi, insects, and plants alike.
In addition, iNaturalist’s project-based ecosystem and integration with conservation tools make it more suitable for research and policy use than purely commercial apps.
