How Viral Swipe File works

  1. Connect your AI agent

    Add the library to Claude, ChatGPT, Grok or Cursor in a minute and sign in with your account. Connecting is free on every plan.

  2. Ask what's working in your niche

    Your agent searches viral TikToks and Instagram Reels by niche, format and creator, ranked by viral factor (views against the account's usual), and reads every hook and caption.

  3. Write tomorrow's post

    Have it write hooks and scripts from those real videos. Or open the library yourself and save the best ones to boards for your team.

Try asking

  • “What should I post tomorrow for a fitness client? Find 10 viral hooks and group them by format.”
  • “Which formats are working in the fitness niche? Show me the videos that beat their account's usual views the most.”
  • “Write 5 hooks for my client [describe them], based on the most viral videos in their niche.”

Frequently asked questions

What is Viral Swipe File?

Viral Swipe File is a curated library of short-form videos that went viral on TikTok and Instagram Reels, for deciding what to post next, on your own or with your AI agent. Each video is filed under a niche and one or more formats, with its hook, caption, creator, views, engagement rate and viral factor, so you start from what already worked instead of a blank page.

What is the viral factor?

How many times more views a video got than its account usually gets. A video at x20 did twenty times its creator's normal numbers, so it is worth studying whatever the size of the account: the idea travelled on its own, not on a big following.

Who is it for?

Social media managers juggling several clients, creators, UGC teams, app marketers and agencies: anyone who has to come up with short-form content ideas every week, often with Claude or ChatGPT open, and wants real hooks and formats that already worked in their niche. Developers and agent builders can use the JSON API and the MCP server.

Is Viral Swipe File free?

Browsing the public pages needs no account. A free account lets you look up niches, formats and creators, scroll the first 100 videos of every list, search, filter and sort, and save videos to 1 board. Starter and Growth open every video in every list, unlimited boards and hook and caption export. Connecting an AI agent is free on every plan, hooks and captions included, and any account can use the JSON API. Free: 50 questions a day (MCP tool calls and API requests together), counted from midnight UTC. Starter and Growth: no daily cap on agent questions; JSON API requests (bulk pulls) are 10,000 requests a month on Starter and 50,000 requests on Growth, counted from the 1st of each month (UTC).

Is this a live feed of this week's trends?

No. It is a library of past viral videos: use it to find hooks and formats with a track record, not to follow what is trending today. It promises nothing about going viral; it ranks videos by how far they beat their account's usual numbers, so you pick what to test.

Can I repost the videos?

No. Every video links to its original post on TikTok or Instagram: use it as a reference for your own video, not as content to repost.

Can I use Viral Swipe File in ChatGPT or Claude?

Yes. Add it as a connector (an MCP server) in Claude, ChatGPT, Grok, Cursor or any MCP client, sign in, then ask things like "What should I post tomorrow for a fitness client?". The connection is free on every plan; setup steps are on the Connect page (/mcp). Connecting an AI agent is free on every plan, hooks and captions included, and any account can use the JSON API. Free: 50 questions a day (MCP tool calls and API requests together), counted from midnight UTC. Starter and Growth: no daily cap on agent questions; JSON API requests (bulk pulls) are 10,000 requests a month on Starter and 50,000 requests on Growth, counted from the 1st of each month (UTC).

How is it different from other viral video tools?

It is curated rather than a raw feed: videos are ranked by viral factor (how far each beat its creator's usual views), with the hook pulled out and the niche and format filed. You and your agent start from real posts by real accounts, so the hooks you write do not come out of a blank prompt.

Can developers use it?

Yes. Every page is also available as markdown, and signed-in accounts can read the JSON API, described in OpenAPI at /openapi.json.
