Stop reading syntax. Start reading documents. A .md file. A JSON export. A notebook, a diagram, a contract to sign. hYYa ink opens them as clean, readable documents instead of walls of raw text, on your Mac, iPhone, iPad and Apple Vision Pro. Reading is free, forever. READ WHAT YOU'RE SENT • Markdown — clean headings, lists, tables and links • JSON, YAML and TOML — tidy trees you can fold and explore • CSV and TSV — a real table, not a wall of commas • Mermaid and Graphviz — diagrams drawn instantly, offline • LaTeX — math that looks right • Jupyter notebooks — cells, code and text outputs, easy to read • AsciiDoc, Org-mode, XML, diffs and logs — readable at last FIX IT WHERE YOU SEE IT Change a JSON value or a table cell right on the page, and only that changes. Sort, filter and find & replace in any table. Write Markdown with a simple toolbar. Edit any text file and see it as a clean document. SIGN, MARK UP AND REDACT PDFS Tap the spot and type. Draw your signature, then place, resize and rotate it. It's a visual signature, not a certified one. Add stamps such as Approved or today's date. Highlight, underline or mark up by hand. Need something gone? Redact removes the selected text from the page. Erase does the same and leaves clean white space. Either way you get a new file, and your original stays as it was. Find any word in a PDF, browse by page or contents, and open password-protected files. Make a scan searchable, right on your device. Reorganize, split, compress, protect or watermark, and each one saves a new file. Compare two PDFs to see which pages differ. TURN ONE FORMAT INTO ANOTHER Save JSON, YAML, TOML and XML as one another, tables as CSV or TSV, notebooks and Org files as Markdown, Markdown and AsciiDoc as web pages, and diagrams as SVG or PNG. If something can't carry over exactly, hYYa ink tells you first. ASK AI, WITH YOUR OWN KEY Explain, summarize or translate a document, PDFs included. Fix errors, reformat, or turn an idea into a diagram. Connect OpenRouter, Groq, Together AI or a compatible service. Your key stays on your device. Only the open document's text is sent, and only when you run an AI action. Every AI result says it was written by AI. PRIVATE BY DESIGN. BEAUTIFUL BY DESIGN. No account. No tracking. No data collection. Documents open on your device without an internet connection, and they stay there unless you choose to send them. FREE TO READ, PRO TO DO MORE Reading every format is free forever, and so are saving as a PDF, printing, and searching or browsing a PDF. Try everything free for 7 days. You are not charged. After that, a one-time purchase unlocks editing, PDF tools, saving in other formats and AI on Mac, iPhone, iPad and Apple Vision Pro. From hYYa — more than apps. Companions you can trust.
