Reads your brand
Your website, brand books, decks and past work become one Brand Spine: who you are, how you sound, how you look, what you talk about.
Writes in your voice
Captions, emails, ads, pages and scripts that sound like you, and never use the words you’ve ruled out.
Designs in your look
Posts, decks, print and pages in your colours, type and layouts, ready to use or to hand to a designer.
Plans the work
Ideas become briefs, briefs become boards and a calendar, with every piece assigned and dated.
Runs the review
Your team and your clients comment on the work itself, ask for changes and approve, in one place.
Learns what works
Results come back to the Spine, so the next piece starts from what your audience actually responded to.
From website to work in four steps.
- 01Bring your brand inPaste your website or portfolio link, or drop in what you have. No brand book needed.
- 02Confirm your Spine/Seiðr drafts your four systems and shows where each line came from. Accept, edit or redraft, then approve.
- 03Set your guardrailsWords to avoid, claims that need proof, colours and type to keep. Every output follows them.
- 04Ask for anythingA post, a launch, a month of content. Review it with your team, approve it, publish it.
