Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Lightkey overview
What is Lightkey?
Lightkey is an on-premises AI-powered predictive typing and spelling correction application for Windows (versions 7, 8, 10, and 11), designed for individual professionals and business users who compose large volumes of text daily. The software integrates directly into over 100 popular Windows applications, including Microsoft Office, Gmail, Outlook, WhatsApp, and Slack, delivering inline word, phrase, and full-sentence predictions without requiring users to switch context or copy-paste between tools. Predictions adapt over time to each user's writing style, vocabulary, and domain-specific terminology, with support for over 80 content domains and more than 85 languages.
The platform operates entirely on-device, meaning no text or behavioral data is transmitted to external servers, making it suitable for professionals in regulated or privacy-sensitive industries such as legal, medical, finance, and government. Spelling correction runs in real time across supported applications, catching errors as text is entered. A dedicated typing statistics dashboard gives users visibility into productivity trends, prediction accuracy, and writing patterns over time. Lightkey is available in Free and Pro tiers, with the Pro tier unlocking extended prediction length, additional domain support, and advanced personalization features.
