Capture a page →

We fetch the page server-side. Some publishers block bots or require login — if a URL fails, use Paste content.

How it works

1

Paste a URL

Any public article, documentation page, or blog post.

2

We extract the signal

Readability finds the main content; nav bars, ads, and pop-ups are left behind.

3

Get portable Markdown

Clean Markdown with frontmatter — links and images resolved to absolute URLs.

4

Save it forever

Download, copy, or open in Obsidian. It's plain text you own — no lock-in.

Built for your long-term memory

MegaFish outputs standard Markdown with YAML frontmatter, so it drops cleanly into the tools you already use to think.

🟣

Obsidian

One click opens a new note in your vault via the obsidian:// URI.

📓

Logseq

Frontmatter + Markdown imports straight into your graph.

📝

Notion & Bear

🤖

AI / RAG

Clean text + metadata makes ideal context for assistants and vector stores.

FAQ

Does it store my data?

No. Pages are fetched and converted on the fly and returned to your browser. MegaFish keeps nothing.

Why won't some pages convert?

The server fetch is anonymous and runs from the cloud, so pages behind a login or paywall, protected by anti-bot rules, or on your internal network won't work this way. For those, use Paste content, or the MegaFish browser extension — it captures the page from your own logged-in browser (so it handles paywalled, JS-heavy, and intranet pages).

What's the frontmatter for?

It records the title, source URL, author, publish date, and tags so each note is self-describing and searchable in your vault — the backbone of durable memory.

How does "Open in Obsidian" work?

It uses Obsidian's obsidian://new URI to create a note in the vault you name. Obsidian must be installed and the vault must already exist.
