Supergrow learns from your inputs and AI interviews to produce LinkedIn posts. Linspire learns from sources you already maintain: your LinkedIn profile (your real expertise) and your website. From there it generates ideas, three post drafts per idea, and lets you tune the output with ICP, Voice, and Custom Instructions across personal and company brands.

Supergrow leans on Postcast AI interviews and existing long-form content as inputs. Linspire works from your LinkedIn profile or your website, both of which you already keep up to date. No new content production required to get going.
Linspire turns each idea into three different post drafts, then lets you compare and edit before scheduling. ICP defines who the post is written for, Voice captures your tone, and Custom Instructions enforce the rules you care about, all configured per brand. Supergrow's Content DNA is account-level and less granular.
Linspire is built for running multiple brands from day one. Each brand has its own profile or website source, ICP, Voice, and Custom Instructions, so a personal account and a company page can run in parallel without one bleeding into the other. Supergrow opens that up at the Teams plan ($139/mo).
Supergrow Starter is cheaper at $19/mo. Linspire wins on the source of ideas (your profile or website rather than interviews), three drafts per idea, ICP and Custom Instructions, profile audit on the free tier, and personal + company brand support out of the box.
Supergrow asks you to produce inputs (interviews, articles, podcasts) and learns Content DNA from them. Linspire reads sources you already have: your LinkedIn profile (your roles, skills, projects) or your website (your products, customers, positioning). The cold-start cost is much lower.
Yes. Each Linspire brand has an ICP (audience definition), a Voice profile, and Custom Instructions applied to every generation. Supergrow's Content DNA is more implicit and operates account-wide rather than per brand.
Not currently. Linspire focuses on text posts and the surrounding profile and voice work. If carousels are essential, Supergrow Pro is stronger.
Yes. Linspire Starter supports 2 brands, Pro 4, and Elite 6, each with its own source data, ICP, Voice, and Custom Instructions. Personal profile and company page typically sit on different brands so the strategies can diverge.
150 credits per month, one brand, no card required. See if your voice matches before you pay.
