A Markdown file (.md or .markdown) is plain text written with lightweight formatting syntax — # for headings, **bold**, - for lists — that renders into formatted text without needing a word processor. It's the default format for READMEs, documentation, and notes across GitHub, static site generators, and note-taking apps. Any text editor can open one, but you'll just see the raw #s and *s; a markdown viewer like Sarvak renders it the way it's meant to look.

Yes, Sarvak is free to download and use today, with no account required. A paid tier with additional features is planned for the future.

Yes. Sarvak renders .ipynb files natively — markdown cells, code cells with syntax highlighting, and outputs — without running a Jupyter server or Python environment.

Yes. Sarvak includes a built-in PDF viewer with zoom, page navigation, and export/print, so you don't need a separate PDF reader.

Sarvak has a built-in Markdown editor with formatting shortcuts, explicit save, and crash-recovery drafts, in addition to its read-only viewers for code, data, and notebook formats.

Yes. Sarvak renders Mermaid diagrams — flowcharts, sequence diagrams, and more — directly inside Markdown files, alongside GitHub-flavored syntax and live formatting.

Yes. Sarvak renders LaTeX math with KaTeX, both inline and display equations — including align and gather blocks — inside Markdown files, and in a rendered preview for standalone .tex documents, with no LaTeX installation required. It also resolves \input and \include, so papers split across multiple files render correctly, not just single-file documents.

Sarvak doesn't run a LaTeX compiler — there's no TeX Live or MacTeX install involved, and it isn't a substitute for compiling a document to a final PDF with custom packages and page layout. Instead, it renders a live preview of your .tex source directly: KaTeX-powered math, structural blocks like sections and lists, and resolved \input/\include files, all instantly and offline. For quickly reading a paper or checking equations without installing a multi-gigabyte TeX distribution, that's usually all you need.

Yes. Sarvak includes a built-in JSON viewer with pretty-printing, syntax highlighting, and collapsible folding for nested objects and arrays, plus similar viewers for YAML and XML.

Yes. Sarvak streams code, log, CSV, and TSV files up to roughly 1GB, reading them in chunks instead of loading the whole file into memory, so huge files open without stalling or crashing the app.

Yes. Sarvak includes a command palette (Ctrl/Cmd+Shift+P), quick open for fuzzy file search (Ctrl/Cmd+O), and project-wide find-in-files, so you can navigate without touching the mouse.

Yes. Sarvak is a native desktop app that reads local files directly. It doesn't require an internet connection, an account, or a cloud service to open, view, or edit your files.

Sarvak ships native binaries for Windows, Linux (.deb, .rpm, and a portable .AppImage), and both Apple Silicon and Intel Macs — most builds are under 6MB, a fraction of the size of Electron-based alternatives.

Yes. Sarvak includes a Parquet table viewer (including GZIP/ZSTD-compressed files, not just the uncompressed default) and a SQLite database browser with a schema/table list and a read-only SQL query box — no database client or Python environment required.

Yes. Sarvak lists a zip, tar, or tar.gz archive's contents — file names, sizes, and full folder structure as an indented tree — without extracting anything to disk. It's browse-only: Sarvak doesn't create or modify archives.

Yes. Sarvak decodes X.509 certificates (.pem, .crt, .cer) and shows subject, issuer, validity dates, subject alternative names, and the SHA-256 fingerprint. Private key files are recognized but deliberately not decoded.
