Clean up AI and web text in one tap. Copy an answer from ChatGPT, Claude, Gemini or any website and it comes with junk: [1] citation tags, 【source】 marks, stray ** and ## symbols, curly quotes, invisible characters, broken line breaks. Text Workflow removes all of it and gives you clean text, ready to paste. Exact, every time, and private. It runs on iPhone, iPad and Mac, and your workflows sync over iCloud. NEW IN 3.0 • Clean AI Text: one action removes citations, hidden characters, extra spaces and Markdown symbols. You choose what goes, and code blocks are never touched. • Remove Citations: strips [1], [7][8], [web:1], 【4:0†source】 and Wikipedia notes. • Markdown tables: tables from AI answers now convert to Rich Text and HTML. Format Markdown Table lines up the columns. • Compare Input with Result: see exactly what changed, by character, word or line. • A new text editor with line numbers, visible spaces and tabs, a monospaced font and Find. • Gemini joins OpenAI and Claude, with the newest models. WHY TEXT WORKFLOW • Exact, every time. The same input always gives the same output. No hallucinations, no "regenerate". • Private. Built-in actions run on your device. Never paste sensitive text into a website just to reformat it. • Built for the whole job. Chain 50+ actions into a workflow, save it and run it with one tap. • On every Apple device. A native app on iPhone, iPad and Mac, with workflows synced over iCloud. CLEAN UP AI AND WEB TEXT • Clean AI Text and Remove Citations • Remove Markdown, or turn it into Rich Text for Pages, Word and Mail • Markdown to HTML, with tables • Convert to plain text, strip HTML tags • Straight and curly quotes, accents and diacritics • Delete invisible and non-printable characters BUILD POWERFUL WORKFLOWS Chain actions together and each step feeds the next.

Clean your clipboard with one tap, or build text automations that run on their own. Use the Share sheet to send text from any app. AI, ON YOUR TERMS AI is one optional step among 50+, not the whole app. Add a prompt step to any workflow with your own OpenAI, Claude or Gemini key, any OpenAI-compatible service such as OpenRouter or LM Studio, or Apple's on-device model. You choose the model and pay the provider directly. Nothing routes through us. TEXT WORKFLOW PRO Free: every action, with results shown in full. Pro lets you copy and share results of any length, create unlimited workflows and compare Input with Result. Payment will be charged to your Apple ID account at confirmation of purchase.
