**RC Slate — the browser that opens your documents, built for people who work with AI.** Tap a document link while browsing — Markdown, DOCX (Word), PDF, JSON, YAML, images — and it opens right there, rendered as a clean page. No downloading, no switching to another app, no wondering what a file looks like before you can see it. **Convert anything to Markdown for AI** Turn documents and web pages into clean, token-efficient Markdown — the same content in a fraction of the prompt size. DOCX converts through the app's own parser; web pages by pulling out the article text. Need the images too? Embed them into a single self-contained Markdown file, with quality presets and a live token estimate. Export any view as PDF, PNG, or HTML. (Markdown conversion is not lossless; full page layout is not preserved.) **Read your Obsidian vault** Add a vault folder and read it as it was written — wikilinks between notes and embedded images. Links resolve inside the folder you added, so a note opens the note it points to. And a vault note leaves as one piece: export it as a single self-contained Markdown file with its images embedded, or as HTML, PNG, or PDF — ready to hand to an AI. Reading only; RC Slate never edits or syncs your vault. **A real browser underneath** Documents are grouped by the site they came from. Switch any article to Reader Mode for a clean, distraction-free reading layout with dark mode. iPhone and iPad layouts, with a sidebar and tab strip on iPad. **Clean pages for every format** - Markdown with tables, syntax highlighting, Mermaid diagrams, and LaTeX math - JSON and YAML: colour-coded, with their keys in the table of contents so you can jump straight to one - DOCX (Word) page by page, view-only (the document's own fonts are not included) - PDF and images **Open files from anywhere** Files on your device open from the Files app — or send a file from any app through the share menu, straight to RC Slate. SelfDrop syncs a file across your devices (up to 20 MB per file). **Works offline** Viewing local files works offline on your device.
