Overview
About SoloTools
SoloTools is an AI proposal generator built specifically for freelancers and independent consultants. Instead of staring at a blank document for hours, you describe your project in 30 seconds — client name, project type, budget, and a few scope notes — and AI generates a polished, client-ready proposal complete with an executive summary, scope of work, itemized pricing, timeline, and standard terms.
Every proposal is fully editable, downloadable as a PDF, and shareable via a branded link. The free plan includes 3 proposals per month. Pro ($14.99/month) unlocks unlimited proposals, custom branding, and proposal view analytics so you know exactly when a client opens your proposal.
