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.

Sheldon overview
What is Sheldon?
Sheldon is a Google Chrome browser extension that embeds a generative AI assistant directly into the browser, allowing users to generate written and technical output without leaving their current tab. Powered by ChatGPT integration, it supports professional email drafting with tone and context control, natural language to code generation with step-by-step instructions, Excel formula generation from plain-language descriptions, and multi-format content creation covering LinkedIn posts, Twitter threads, website copy, video scripts, and blog posts. The extension operates in-context across widely used platforms including Gmail, Google Sheets, LinkedIn, and Quora. A free tier with no daily data limits is available, alongside a paid upgrade tier for additional capabilities.
Sheldon targets individual users, including freelancers, content writers, and software engineers, who perform high volumes of writing, coding, and content creation tasks across the web. By surfacing AI generation tools directly within the browser interface, it removes the need to switch between standalone AI tools and active workspaces. The extension is currently limited to Google Chrome, with support for additional browsers planned. All core features are accessible on the free tier, and the platform is continuously updated as the generative AI landscape evolves.
