Our Review
4.0 / 5.0
Spelly presents itself as a compelling alternative in the realm of writing assistance tools, particularly for users who are highly conscious of their data privacy. By leveraging AI to perform spell and grammar checks directly on the user’s device, it addresses a significant concern often associated with cloud-based services. The tool is straightforward to install and integrate into daily browsing, providing immediate feedback on typing errors. While it excels in its core function of accurate, private correction and supports multiple languages, it currently focuses primarily on basic spelling and grammar. Users looking for more advanced features like style suggestions, tone analysis, or plagiarism checks might find it less comprehensive than some larger competitors. However, for reliable, privacy-centric writing assistance, Spelly is an excellent, free solution.
