What it is

ClientWin OS is web-based AI proposal software for freelancers, solo consultants, small agencies and other service providers. Its workflow checks opportunity fit, guides pricing, matches relevant proof, drafts a proposal, shares a Client Deal Room link and tracks responses and outcomes. Users review and send every proposal themselves; the product says it does not scrape platforms or submit proposals automatically. The Free plan is billed at $0 per month and includes one proposal generation, five AI Actions, three manual Proof Vault items and basic PDF or share export. Starter costs $13 a month, Pro costs $26 a month and Agency costs $68 a month. Paid plans increase monthly allowances and add capabilities such as proof import, branded exports, client rooms, automated workflow and team collaboration. Proposal generations and AI Actions have separate allowances; automated workflow on Pro and Agency uses those same allowances. Private workspace data is not used to train public AI models, though relevant data may be sent to third-party AI providers. Platform Intelligence is off by default.
