SoloTools
AI-Powered Proposal Generation
The core feature of SoloTools is its intelligent AI engine. It does far more than fill in templates. Based on the brief project details you provide, the AI writes a compelling, tailored proposal from the ground up. It crafts persuasive executive summaries, breaks down the scope of work into clear phases, structures professional pricing tables, and outlines project timelines and terms. This ensures every proposal is client-ready, coherent, and professionally formatted without any manual writing effort.
AI Section-Level Editing
After the AI generates your proposal, you retain full control with smart editing tools. For any section of the proposal, such as the executive summary or scope, you can instruct the AI to refine the text on the spot. You can use simple commands like "Make more persuasive," "Make shorter," "Make more detailed," or "Rewrite in formal tone." This allows for quick, intelligent customization without having to manually rewrite entire paragraphs, saving even more time while perfecting the message.
Client Tracking & E-Signatures
SoloTools manages the entire client interaction after the proposal is created. You can send proposals directly to clients via email with a personalized message. The platform then provides real-time analytics, notifying you the moment a client opens your proposal for the first time. Most importantly, it includes a built-in canvas for clients to provide legally-binding e-signatures directly on the document, streamlining the acceptance process and eliminating the need for separate signing software.
Proposal Analytics & Automation
This feature provides valuable insights into your business performance. You can view a clear conversion funnel showing how many proposals were sent, viewed, accepted, or declined. This helps you understand your win rate and identify where you might be losing deals. Furthermore, the tool offers automation like automatic follow-up reminder emails (set for 3, 5, or 7 days) and the ability to set proposal expiry dates to create urgency, helping you manage the follow-up process without manual effort.
