![Write Markdown, see the page](brand/producthunt/07-live-preview.png)

Documents arrive in the wrong shape. A Word file you need as Markdown. A Notion export that is
forty pages in a zip. A spec your assistant wrote, gone once the chat scrolls away. Markdown pasted
into an email, landing as a wall of asterisks.

TransformPipe turns all of them into one thing: a clean Markdown document. See it as a finished
page, take it away as Markdown, HTML, Word, PDF, Confluence, Jira, Slack or EPUB, or keep it and send a link instead of an
attachment. Open [transformpipe.com](https://transformpipe.com) and drop a file. No account is
needed to convert.

## Twenty conversions, in your browser

Word, PowerPoint, Excel, EPUB, OpenDocument, rich text, HTML, CSV, JSON, plain text, Evernote, or a
whole Notion, Confluence or Obsidian export. Each comes back as Markdown with its headings, lists,
links and tables intact, and Markdown goes the other way: into a finished page, a Word document, a Confluence page,
a Jira ticket, a Slack message or an EPUB book.

The conversion runs on your machine. Signed out, nothing is uploaded and nothing needs a network.
Drop several files and they become one document, in the order you picked them.

## Markdown in, a finished page out

Tables, code, task lists, maths and Mermaid diagrams come out the way they were meant to look. The
download is one self-contained `.html` file that fetches nothing when it opens: no scripts and no
webfonts. A saved document also downloads as Word, and any document
prints to PDF.

![Markdown in, a finished page out](brand/producthunt/04-markdown-to-a-page.png)

## Send a link, not an attachment

Share a saved document with anyone who has the link, or only with the addresses you name. Give the
link a password or an end date if it needs one, and see how often it was opened. **Make private**
stops it in one step, and the old link stops working for good.

Publish new text from the API, the command line, an assistant or Obsidian, and the link people
already have shows it. The text it replaced is kept as a revision.

## What your assistant writes, kept

TransformPipe is in [Claude's connector directory](https://claude.ai/directory/tp): press
**Connect**, sign in, and ask in plain words. "Save this as the Q3 plan." "Publish it and give me
the link." "Find the migration spec from last week." The document goes into your account, with a
title you can search for, long after the chat has scrolled away.

ChatGPT [connects too](https://transformpipe.com/agents/chatgpt), by address, as an MCP app, and
Obsidian has a [community plugin](https://transformpipe.com/agents/obsidian). All three see the same
documents.

## One library, not forty chats

Everything you convert, save or have an assistant save lands in one list: searchable, filtered by
format, with versions side by side and a line-level diff between them. Signed in, it is the same
list on every device.

![One library, not forty chats](brand/producthunt/09-one-library.png)

## Any web page, as Markdown

The [browser extension](https://transformpipe.com/extension), for Chrome and Firefox, takes the page
you are on and hands back the article without the navigation or the cookie notice. Copy it, download
it, or save the page as a self-contained `.html` file. Signed out, it never talks to us.

## Your documents, your account

An assistant acts as you, on your documents only. It cannot change the account, see your password
or create API keys, and it deletes nothing without an explicit confirmation. A grant can be
read-only. The service is free, and the limits are written down: 5,000 documents and 250 MB an
account, 4 MB a document. Reaching one refuses the save; nothing is deleted to make room.

## Every way in

- **The web app** at [transformpipe.com](https://transformpipe.com): convert, preview, keep and
  share.
- **Claude**, from the [connector directory](https://claude.ai/directory/tp) on claude.ai and in
  Claude Desktop, or by [address](#in-an-assistant) in Claude Code.
- **ChatGPT**, as an MCP app: [the three steps](https://transformpipe.com/agents/chatgpt).
- **The [browser extension](https://transformpipe.com/extension)**, for Chrome and the browsers
  built on Chromium, and for Firefox on the desktop and on Android.
- **[TransformPipe for Obsidian](https://community.obsidian.md/plugins/transformpipe)**: publish a
  note as a page, and keep the same link after every edit.
- **A script**: the [API](#api), the [command line](#from-a-terminal) and a
  [GitHub Action](#as-a-github-action).

## Conversions

Live at **[transformpipe.com](https://transformpipe.com)**. The old `md-2-html.vercel.app` still
answers, so links already shared keep working; the canonical URLs, the sitemap and every default in
the CLI and the Action name the new domain. Nothing in `server/` carries a domain at all — origins
come from the request through `selfOrigin`, which is what made the move a matter of one trusted
origin and a rebuild.

Upload a file, see exactly what it became, and download it. Twenty conversions, each with its own
page and address:

They all normalise to Markdown, which is what a document is stored, previewed, shared and reached
by a script as — one shape rather than fourteen. Any document can then be handed over as Markdown,
HTML, plain text, Word, Confluence, Jira, Slack, EPUB, or printed to PDF. `shared/conversions.ts` is the single list; the header menu, the
screens, the history chips, the badges and the prerendered pages all read it, so a new conversion is
an entry there plus a converter.

`.txt` used to be accepted on the Markdown → HTML page as if it already were Markdown; it has its
own conversion now instead, because a plain-text file is not Markdown even when it looks like it —
an asterisk typed as a literal asterisk and one meant as emphasis are the same character, and only
one of the two conversions is supposed to treat them alike.

Notion, Confluence and Obsidian are the three that do not produce one document from one file: each
export is several pages (or notes) in a `.zip`, and each comes back as a single Markdown document —
a table of contents, then every page in order, each a heading of its own (`shared/from-notion.ts`,
`shared/from-confluence.ts`, `shared/from-obsidian.ts`, sharing the zip-reading and merge convention
in `shared/zip-imp
