Writesonic is an AI service that first became known as a tool for creating marketing copy. The provider now positions itself as a platform for visibility in both traditional and AI-powered search: it aims to measure how often a brand is mentioned in AI assistants' answers and to improve content for SEO and generative engine optimisation (GEO) (as of October 2026). Its main audience is marketing teams and agencies.
Generative engine optimisation (GEO) covers measures that help content become visible in, and be cited as a source by, AI-powered search systems such as ChatGPT, Perplexity or the AI overviews in search engines. The term comes from a 2023 research paper. Key factors include clear, directly quotable answers, a clean structure, evidenced facts, up-to-date information and identifiable authors. GEO complements classic search engine optimisation (SEO) rather than replacing it.
An SEO score is a metric that analysis tools use to rate how well a web page is optimised for search engines – usually on a scale from 0 to 100. Factors may include titles and descriptions, heading structure, loading speed, mobile-friendliness, internal links and structured data. Every tool calculates the score differently; it is not an official Google rating. The score is therefore useful as a checklist for improvements, not as a guarantee of good rankings.
Writer (writer.com) is a US company founded in 2020 that offers a platform for generative AI in the enterprise. It develops its own family of language models called Palmyra and provides tools with which companies can build AI agents, connect them to their own knowledge and govern them with rules on brand voice and approvals (as of October 2026). It is used mainly for content and workflows in marketing, sales and customer communication.
Jasper is an AI platform for marketing teams from Jasper AI, a US company founded in 2021. It helps create copy such as blog posts, adverts or social media posts and can take stored brand guidelines and tone of voice into account. The provider now positions itself around specialised agents and automated content workflows (as of October 2026). As with any text generator, facts and claims should be checked before publication.
