A beautiful editor, AI that refines your words (never replaces them), and publish to your own domain — all from a single workspace. Built for writers who care about their craft.
Indie bloggers, devs & creators waiting for launch

Postwai gives you a professional blogging toolkit without the complexity of WordPress or the lock-in of Substack.
Tiptap-powered rich text with slash commands, markdown shortcuts, drag-and-drop images, code blocks with syntax highlighting, and autosave. Writing should feel effortless.
Grammar cleanup, tone adjustment, SEO suggestions, and auto-excerpts. Every AI suggestion shows a side-by-side diff. You approve every change. Your voice stays yours.
Run a tech blog, a travel journal, and a newsletter from one account. Each workspace gets its own domain, theme, tags, and team. Switch in one click.
Publish to your own custom domain with automatic SSL. Or start instantly with a free postwAI subdomain. Your content, your URL, always.
Use the managed blog or bring your own frontend. REST and GraphQL APIs let you pull your content into Next.js, Astro, mobile apps — whatever you build.
Write in one language, translate to many. AI-assisted translation drafts with human review. Locale-aware URLs, RTL support, and per-language RSS feeds.
Each workspace is a separate blog with its own domain, theme, and content. Create as many as you need.
Use the rich editor to write. Hit the AI button to polish grammar, adjust tone, or optimize for search.
Publish to your custom domain instantly, schedule for later, or pull content via API into your own frontend.
SEO baked in. RSS feeds. Social cards. Newsletter integration. Analytics to see what resonates.
