ClientWin OS vs FirstSlate

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.

FirstSlate is a web-based client workflow platform for independent video producers and creative agencies. It brings client intake, AI proposal drafting, call sheets, crew paperwork, a teleprompter, delivery, invoicing and payments into one workflow. Clients and crew can use links without creating FirstSlate accounts or passwords. Clients can pay invoices by card or ACH through Stripe; FirstSlate says it charges 0% platform fees. The AI assistant drafts proposal content from a project brief using Google Gemini. Pro and Studio workspace owners can connect MCP clients such as Claude, ChatGPT and Gemini to read data and create drafts. Every new account starts with a 14-day Pro trial without a credit card, then returns to Free unless upgraded. The Free plan allows five active projects, 20 archived projects and three clients. Paid plans start at $15.83/mo equivalent, billed annually. Studio is listed at $66 a year, billed annually at $790/yr, and includes three team seats and priority support.
