Sky Identify is an online recognition tool for night-sky photos and screenshots. Users can upload or drag and drop an astrophoto, and the system attempts plate solving to estimate RA/Dec coordinates, field of view (FOV), rotation angle, and sky orientation. Once solved, it highlights and labels Messier and NGC objects. It is more of an astrophotography utility than a general-purpose image recognition app.
Based on the page information, Sky Identify centers on a fast plate-solving pipeline, with an emphasis on star matching and outlier rejection to improve solving reliability. It supports JPEG/PNG files, with a maximum single-file size of 25MB, and offers an in-browser demo. The output covers key astronomical positioning parameters: RA/Dec, FOV, rotation, sky orientation, as well as labels for some deep-sky objects. The limitations are that it does not disclose the star catalog source, algorithm details, error ranges, or how it performs with light pollution, clouds, fisheye distortion, or photos with relatively few stars.
The captured content does not provide information on pricing, free quotas, account systems, or payment methods, so its business model cannot be assessed for now. There is also no mention of an API, batch processing, or integration with astronomy software such as PixInsight, Siril, or ASTAP. At this stage, it looks more like a lightweight web tool or demo product, suitable for quickly identifying a single image, but it should not be assumed to support professional pipeline automation.
The main advantage is that the workflow is very straightforward: upload an image and get a result, with output that is genuinely useful for astrophotography users. If it truly runs entirely in the browser, that could also help reduce waiting time and server dependency. The downside is the lack of disclosure, especially around privacy policy, whether files are stored, accuracy metrics, failure conditions, and service support. File format and size are also limited, with support only for JPEG/PNG up to 25MB.
It is suitable for astrophotography enthusiasts, stargazers, and users who need to quickly confirm which area of the sky a photo is pointing at. For research-grade high-precision solving, batch astronomical data processing, or stable automation interfaces, it is worth also considering plate-solving options from Astrometry.net, ASTAP, Siril, or PixInsight. Access from mainland China is not covered in the source text, so network connectivity, payment availability, and local alternatives would all need to be tested in practice.
