Writesonic is an AI marketing platform that combines advanced content generation with generative engine optimization (GEO) and SEO automation. It enables marketing teams, agencies, and fast‑growing brands to see exactly how their brand appears in AI search results (ChatGPT, Gemini, Claude, Perplexity and more) and then take specific actions to improve visibility—creating new content, refreshing pages, and earning citations on authoritative sites.
Founded by Samanyou Garg in October 2020 and headquartered in San Francisco, Writesonic graduated from Y Combinator’s Summer 2021 batch and has grown to serve tens of thousands of teams and millions of individual marketers worldwide. The company began as an AI writing assistant focused on blogs, ads, and landing pages, and has since evolved into a full GEO and SEO platform that analyzes 120M+ AI conversations, tracks AI bot traffic, and connects directly to tools like Ahrefs and Google Search Console to drive data‑backed recommendations.
The product now spans several modules: an AI Article Writer that generates fact‑checked, SEO‑optimized long‑form content using real‑time web and competitor data; an SEO Suite for keyword research, content grading, internal linking, and technical audits with AI-powered fixes; AI Traffic Analytics and AI Search Volume Explorer for understanding real AI prompt demand; and a GEO Action Center that surfaces prioritized tasks to close AI visibility gaps. On top of this, Chatsonic provides multi‑model AI chat (GPT‑4o, Claude, Gemini, and others) with browsing, data analysis, and image generation, while Botsonic offers a no‑code way to build AI chatbots on top of a company’s own knowledge base.
Backed by investors including Y Combinator, HOF Capital, Rebel Fund, Soma Capital, and others, Writesonic has raised a few million dollars in seed funding and reports strong revenue growth as it moves from a pure AI writing tool into a broader AI search and SEO automation platform. With SOC 2 Type II, GDPR, and HIPAA compliance, as well as 4.7+ ratings on major review sites, Writesonic positions itself as a best‑of‑breed solution for organizations that care not only about producing content at scale, but also about winning visibility in both traditional and AI‑driven search.
