Threads Hook Extractor

Threads Hook Extractor

Paste a viral Threads post or thread URL. Get back: which hook formula it uses, the exact structure, why it worked, and a blank template you can fill with your own voice.

When to use

• User finds a viral post or thread they want to study
• User wants to replicate a specific creator's pattern
• Before threads-post-writer, to seed a draft with a proven shape

Input

A Threads post or thread URL (threads.net or threads.com, /@handle/post/). For a thread, the URL of the first post is best.

Output

• Formula identified (T1-T10 from ../../references/hook-formulas.md) with a

confidence score

• Container: single post vs thread, and why that container fit the idea
• Structural breakdown:
• The hook line (and for a thread, how post 1 opens the loop)
• Body architecture (per-post roles for a thread)
• The close (what earns the repost or the reply)
• Reaction-triggering devices (numbers, named entities, the open loop, the warm

invite)

• Primary goal the original chased (replies / reposts / likes / quotes)
• Why it worked psychologically and algorithmically
• Blank template with {slot} markers matched to the original, ready for the

user's topic

• Cautions: anything in the original that would fail a 2026 audit (em dashes,

AI vocab, 2+ hashtags, link in post 1, a cold X tone)

Steps

1. Parse the URL. lib.url_parser.parse_threads_url(url) returns handle,

post_id, url_type.

1. Get the text. This bundle has no built-in post reader, so ask the user to

paste the post or the full thread text. (If they later wire an Apify post-read actor, read it automatically.)

1. Detect the container. One self-contained post, or a multi-post thread.
2. Classify against the 13 formulas using features:

• Single post: a warm contrarian claim (T1)? one hard number (T2)? a personal

metric/confession (T3)? a quote post adding a layer (T4)? a one-line-per-item list (T5)? a relatable shared moment (T6)?

• Thread: a numbered teaching promise (T7)? a story starting at the tension

(T8)? a surprising result with the mechanism withheld (T9)? a first-person "how I" teardown (T10)?

1. Score confidence. If two formulas fit, return the top 2 with fit scores.
2. Extract structure. Label each part by its role. For a thread, map post 1

(the loop), the front-loaded payoff, the body beats, and the closer.

1. Name the primary goal the original optimized for.
2. Generate a blank template with {slot} markers matched to the original

shape and the user's topic.

1. Audit the source. Flag any AI tells in the original so the user does not

copy them.
