In their own words
BriefSmith
BriefSmith is web-based proposal software for agencies that drafts proposals and checks their scope before they reach clients. It creates structured documents with an executive summary, approach, deliverables, timeline, investment, payment terms, and scope limits. Its checks flag vague deliverables, missing limits, scope gaps, and over-promises. Teams can set shared proposal structure, tone, and scope limits, then export proposals as branded PDFs or individual proposals as Word documents. BriefSmith tracks proposal status, client opens, and win-rate trends. Its free Scope Check requires no signup and flags scope risks; BriefSmith says submitted text is read once and discarded. The 14-day trial with a card includes the full product without a proposal limit; the no-card option includes three generated proposals. The Founding Member plan is $29 a month, billed at $29/month, with a founding rate locked while subscribed for the first 50 agencies. Briefs are processed by Anthropic, and BriefSmith says content is not used to train AI models.
