AI-Powered Proposal Generation

Go beyond basic templates with an AI that writes and refines your proposals.

You describe the project in a few words, and in about 12 seconds, you have a complete, client-ready draft.

Intelligent AI Section-Level Editing

Maintain full creative control with powerful, context-aware editing tools.

This allows for rapid refinement and customization without starting from scratch, ensuring the final document perfectly matches your voice and goals.

Complete Client Experience & E-Signatures

Manage the entire proposal journey within SoloTools. Send proposals directly to clients via one-click email with a personalized message.

Freelance Web Designers & Developers

Integration is straightforward due to its API-first design. BlitzAPI provides clean, well-documented REST APIs that can be connected to your CRM, marketing automation platform, or custom internal tools in just a few hours. It's built to fit into your process, not the other way around.

How does the AI proposal generation work?

You provide basic project information such as the client name, project type, budget, and a few key scope notes.

It creates all standard sections, including an executive summary, detailed scope of work, pricing table, timeline, and terms, tailored to your specific details.

Is there a free plan available?

Simply select any section and choose options like "Make more persuasive" or "Make shorter" to have the AI rewrite it on the spot.

How do clients sign the proposals?

SoloTools includes a built-in e-signature feature. When you send a proposal to a client, they can review it online and, if they accept, draw their signature directly on the document using their mouse, finger, or stylus. This creates a legally-binding electronic signature, and you receive an instant notification once the document is signed.
