# Slack

## Profile

A mainstream messaging application — already installed on most knowledge workers' devices, with native mobile + desktop clients and webhook support.

## Role in This Source

The speaker's recommended **frictionless capture front-end** for the [[concept-open-brain-d22]]. A private Slack channel hooked to a webhook into a [[entity-supabase-d22]] edge function lets the user log a thought, decision, or constraint in **under 5 seconds** — see [[action-setup-frictionless-capture]].

The rationale: the capture UI is the highest-leverage friction point in any personal memory system. If logging takes 30 seconds and a folder decision, the system fails. If it is 'type into the same Slack you already have open,' adoption becomes automatic.

Fits in the **Capture** step of [[framework-open-brain-architecture]].
