Writers publish somewhere that already has a feed and collect readers somewhere that already has a signup form, so a bio link shouldn't mean retyping either. BioFlow reads your feed so you can pick a post onto the page instead of pasting links, embeds the subscribe form of the platform you already use, and leaves the rest of the page for the work you want read first.
Embed your Substack or beehiiv subscribe form, sign readers up to Kit or Mailchimp, or collect them straight into Contacts.
Pick a post from your RSS feed into a Link block and it stays synced to that post, checked hourly — or point one at the store that sells your book.
A short bio, a pull quote, or a reading list — formatted text with headings, lists, and links.
Pin the post that opens your best thread as a clean quote card in your own theme, with no X tracking scripts.
Your Bluesky profile and latest posts, with a follow button.
4 of these are basic blocks, unlimited on every plan. The other 1 block is premium. Premium blocks are capped per page: 2 on Free, 10 on Creator, unlimited on Pro. See pricing for the full plan matrix.
Connect each of these once and the blocks it feeds stay in sync with the source. For a feed or a channel, you pick the post or video to show, and that block keeps tracking it. Every integration is included on every plan, Free included.
Pick posts or episodes from any blog or podcast feed onto your bio page, and each one stays in sync with the feed.
What syncs & how to set it up →Grow your Kit list from your bio page — forms and subscriber counts synced automatically.
What syncs & how to set it up →Collect subscribers from your bio page straight into your Mailchimp audience.
What syncs & how to set it up →Nothing here happens behind your back. Whatever the agent changes lands in your draft; nothing goes live until you publish. If you already have a page somewhere else, tell the agent what's on it — your links, in order — and it rebuilds them in BioFlow; see how BioFlow compares to Linktree for the head-to-head.
Prefer to drive it yourself? Any MCP-capable assistant — Claude, ChatGPT, Copilot — can edit the same page on every plan, and your own code can through the public REST API on Creator and Pro. See the MCP server and the developer platform.
Yes. Set the Newsletter block's provider to Substack or beehiiv — for Substack paste your publication URL, for beehiiv paste the embed URL of a beehiiv subscribe form — and the block embeds that platform's own form, so readers join the list where it already lives. For Kit or Mailchimp, connect the account and pick the form or audience new subscribers land in.
Yes. Connect your blog's RSS or Atom feed — paste the URL, no sign-in — and pick a post from it into a Link block. That block stays synced to that post: the feed is checked hourly by default, every 30 minutes at the fastest, and an unchanged feed costs nothing to check.
Yes. BioFlow runs an MCP server on every plan, including Free. Connect Claude, ChatGPT, or Copilot with OAuth, approve the scopes it gets, and it can read your page and edit the draft. Publishing is off by default, and even once you turn it on, every publish takes a second confirming call.
Yes, on Creator and Pro. The public REST API creates pages and adds and removes blocks in your draft; publishing is a separate call, and idempotency keys make retries safe. A TypeScript SDK wraps it, and the API allows 10,000 requests a month on Creator and 100,000 on Pro.
