SoloTools
AI-Powered Proposal Generation
This is the core intelligence of SoloTools. Instead of filling out rigid templates, you describe your project in plain language. The AI then writes a complete, tailored proposal from scratch, including persuasive executive summaries, detailed scope breakdowns, and professional pricing tables. It goes beyond simple fill-in-the-blanks, understanding context to create a document that speaks directly to the client's needs and your unique value proposition, all in roughly 12 seconds.
AI Section-Level Editing & Refinement
Maintain full creative control with intelligent editing tools. For any section of your AI-generated proposal—like the executive summary or scope of work—you can issue natural language commands such as "Make more persuasive," "Make shorter," or "Rewrite in a formal tone." This allows for rapid refinement and customization without starting from scratch, ensuring the final document perfectly matches your voice and the project's requirements.
Complete Client Workflow & E-Signatures
SoloTools manages the entire proposal lifecycle from send to signature. Send proposals directly via email with a personalized message, track when clients view them in real-time, and collect legally-binding e-signatures seamlessly within the platform. Clients can draw their signature directly, and you can set expiry dates to create urgency, eliminating the need for back-and-forth emails and separate signing tools.
Proposal Analytics & View Tracking
Gain valuable insights into your business development process. See a clear conversion funnel showing how many proposals were sent, viewed, accepted, or declined. Receive instant email notifications the moment a client opens your proposal for the first time, enabling perfectly timed follow-ups. These analytics help you understand what's working, identify bottlenecks, and ultimately improve your win rate.
