30-Day Social Content Generator

For owner-operators who know they should post and never know what: answer eight questions and get 30 captions across 12 content pillars, sized and hashtagged for your platform, ready to paste into Buffer or Later.

Business name

Business type

City / region (optional)

What you sell (one line)

Comma-separated items become hashtags and get used one at a time in captions.

Posting days per week

Three things customers ask most (optional — used by the Customer Question and FAQ pillars)

Use AI (optional) — bring your own Anthropic key

The template calendar above works without a key. With a key, one request rewrites all 30 captions around your business specifics; anything that fails our checks keeps the template version. Your key is sent only to api.anthropic.com from your browser. Sigma Foundry never sees it.

Posting is half the job; following up on the replies is the other half. If DMs and comments turn into quotes that go quiet, the Lost Revenue Calculator shows what that leak costs you per month.
