Feature Comparison
SoloTools
AI-Powered Proposal Generation
Go beyond basic templates with an AI that truly understands context. In roughly 12 seconds, it generates a complete, polished proposal tailored to your project. It writes persuasive executive summaries, breaks down the scope of work with clarity, structures professional pricing tables, and drafts persuasive terms and conditions. This intelligent core ensures every proposal is uniquely crafted to impress your specific client and win their confidence from the first read.
Intelligent Section-Level Editing
Maintain full creative control with powerful, AI-driven editing. For any section of your proposal—like the executive summary or scope—you can give specific commands such as "Make more persuasive," "Make shorter," or "Rewrite in a formal tone." The AI refines the content on the spot, allowing you to perfect the messaging without starting from scratch. This feature ensures your voice and strategic goals are always front and center in the final document.
Client Engagement & E-Signature Tools
Streamline the entire closing process from sent to signed. Send proposals directly to clients via email with a personalized message. Then, track their engagement with real-time notifications for when they open your proposal. Clients can accept and provide a drawn e-signature directly on the document, or decline with an optional reason. This integrated system eliminates back-and-forth emails and chasing for signatures, making the process professional and effortless.
Proposal Analytics & Automation
Gain valuable insights to win more deals. The dashboard shows your complete conversion funnel, tracking proposals from "Sent" to "Viewed" to "Accepted/Declined." Understand your win rate and where you might be losing deals. Set automatic follow-up reminders and proposal expiry dates to create urgency. With Zapier-ready webhooks, you can connect this data to your other business tools, automating your workflow and ensuring you never miss a follow-up opportunity.
