It supports long-form writing, 50 content templates, multilingual content, team collaboration, and SEO features. For existing content, it can analyze a URL and create a refresh, rewrite, outperform, or repurpose version. The homepage lists GPT-5.4, Claude Opus 4.6, and Gemini 3.1 Pro. Byword says it can publish to WordPress, Webflow, and four other CMSs. Its integrations documentation names WordPress, Webflow, Ghost, HubSpot, Medium, Notion, Google Docs, Google Sheets, Airtable, Slack, webhooks, and API; integrations require a paid plan, and multiple platforms can be connected at once.
