As answered by people managing Codility and Voxly.ink.
Voxly.ink's answer:
Voxly is built around a research-driven idea-to-post agent. Instead of spitting out generic copy from a one-line prompt, you give it a rough idea plus references like links, quoted posts, and snippets, and it researches the topic and drafts a post in your voice. It learns a voice profile from your style, handles single posts, threads, and long-form articles, and lets you refine any draft through a chat-based, targeted-edit tool before publishing straight to X. The whole point is on-brand, research-backed drafts you still control, not one-click AI filler.
Voxly.ink's answer:
Most X tools do one of two things: schedule posts (Typefully, Hypefury, Buffer) or generate from viral-tweet templates (Tweet Hunter, Postwise). Voxly does the part they skip. It actually researches your specific idea and its references before writing, and matches your voice instead of a generic "viral" tone. You get a focused editor, thread and article support, chat-based inline edits, and shareable preview links, without the bloated CRM/automation suites or the steep tiers those tools hide their AI behind.
Voxly.ink's answer:
Founders, solo creators, indie hackers, and small marketing teams who want to grow on X/Twitter but don't have time to write consistently. The sweet spot is people with real expertise and ideas who struggle to turn them into polished, on-brand posts, and who want AI to handle research and drafting while they keep editorial control.
Voxly.ink's answer:
Posting consistently on X is a grind. You've got ideas, links, and half-formed thoughts, but turning them into posts that actually sound like you takes time most builders don't have, and the existing AI tools just produced generic, off-voice copy. Voxly was built to do the harder part: research an idea and its references, then draft something in your own voice that you can edit and ship in minutes.
Voxly.ink's answer:
Next.js 16 (App Router) and TypeScript on the frontend and backend, Supabase (Postgres, Auth, Storage) for data and accounts, the Vercel AI SDK plus Vercel AI Gateway to orchestrate the AI drafting (model-agnostic across frontier LLMs), and the official X API for publishing. UI is Tailwind CSS with shadcn/ui, deployed on Vercel. Billing runs through Creem and transactional email through Resend.
