In Slack

Three ways to ask.

Channel, DM, or slash command: every answer comes from the same coworker, grounded in the accounts you track.

Mention it in a channel

Ask in front of the team. Hook replies in-thread and keeps answering follow-ups, even when nobody tags it.

DM it directly

A private line for the questions you're not ready to ask in #marketing. Same brain, same cited sources.

Run /hook anywhere

One command from any channel. Question in, cited answer back in the thread.

Why the answers are different

Grounded in your ecosystem, not the internet's average take.

Hook answers from the competitors and creators you actually track, and cites the videos behind every claim. Every number is boost-checked against the Meta Ad Library first, so spend never reads as a trend.

The answer in #marketing, the script drafted in the app, and the tool call your agent makes in Claude all draw on the same tracked accounts and the same boost-checked numbers. Pick the surface that fits the moment, the grounding never changes.

Why is Halftide out-reaching Northbound on organic?
Hookget_top_posts

Across your set, POV demo reels travel furthest. Northbound sits #2 of 7 on reach-per-follower. You punch above your size. The real gap is paid: 1 live ad vs ~6 per rival.
