Writesonic

Writesonic is an AI content and search visibility software company, independent and based in San Francisco since 2016, with one platform for marketing teams.

Writesonic is an AI software company in San Francisco, independent since it started in 2016, and its main product carries the same name. That product is an AI content and search visibility platform. It tracks how a brand appears in ChatGPT, Gemini and Google AI Overviews, and gives marketing and SEO teams the article writing, site auditing and workflow tools to change what those answers say. The company sells to marketing teams, SEO teams and agencies on one subscription that covers the whole platform rather than a separate purchase per job. Its work has two halves. The first is generative engine optimisation, measured in citations, sentiment and share of answer inside AI assistants. The second is conventional content production, measured in articles published and pages audited. Chatsonic, the company's chat assistant, signs into the same account and is part of the platform rather than a product of its own. Botsonic is the company's second product, a no-code AI chatbot and agent builder with its own site, sign-up and plans at botsonic.com, sold to support teams that want a bot trained on their own content. Writesonic publishes its plan limits on prompts tracked, articles, audits, seats and projects, and states SOC 2 Type II, GDPR and HIPAA compliance for enterprise buyers. Support runs by email, with a dedicated AI search strategist at the top tier.
