Squiggle
Slack-integrated photo annotator. Quick markup, no context switch.
Problem
- Circling one thing in a screenshot meant leaving Slack, opening an editor, saving, and uploading again.
Approach
- A Slack app: upload, annotate, share, all in the flow.
- The work is mostly in the integration: interactive components, message updates, file permissions, OAuth scopes.
Outcome
- Shipping a real integration is a humbling exercise in reading other people's docs carefully.
A Slack app for the moment when you want to circle one thing in a screenshot and post it back to the channel. Circling one thing in a screenshot meant leaving Slack, opening an editor, saving, and uploading again. Squiggle removes the round trip: upload, annotate, share, all in the flow.
The work is mostly in the integration. Slack’s app contract has more sharp edges than a casual user would guess: interactive components, message updates, file permissions, OAuth scopes. Each one is documented, and each one is documented somewhere slightly different from where you expect.
The lesson it reinforced: shipping a real integration is a humbling exercise in reading other people’s docs carefully. The annotation itself is the easy part; the product is the plumbing that makes it feel like Slack already had the feature.
