Feature Comparison

SoloTools

AI-Powered Proposal Generation

This is the core engine. Forget filling out static templates line by line. Our AI intelligently writes full, contextual proposals from your brief inputs. It generates compelling narratives in the executive summary, breaks down the scope of work with clarity, structures professional pricing tables, and drafts persuasive terms and conditions—all tailored to your specific project type and details. It's like having a professional copywriter in your pocket, working at lightspeed.

AI Section-Level Editing & Refinement

Got the draft but want to tweak the vibe? Our AI editing is next-level. Don't just edit text; command it. Highlight any section—like the executive summary or scope—and use one-click commands like "Make more persuasive," "Make shorter," or "Rewrite in formal tone." The AI instantly rewrites that specific part to match your instruction, giving you granular control over the tone and impact without starting from scratch.

Client Experience & E-Signature Suite

Close deals frictionlessly. Send proposals directly via email with a personalized message right from the dashboard. Clients receive a clean, professional interface to review, ask questions, and sign. They can draw their signature directly on the document for a legally-binding e-signature. You can even set expiry dates to create urgency and automate polite follow-up reminders, so you never have to send an awkward "just checking in" email again.

Proposal Analytics & Tracking

Knowledge is power, and SoloTools gives you the intel. See the exact moment a client opens your proposal with real-time view notifications. Track your entire conversion funnel from "Sent" to "Viewed" to "Accepted" or "Declined" to identify where you're losing deals. Monitor your overall win rate and average close time to understand exactly what's working in your business development process.

Frequently Asked Questions

SoloTools FAQ

How does the AI know what to write in my proposal?

Our AI is trained on thousands of successful proposals across various industries like web design, marketing, and consulting. When you input your project details (type, budget, scope notes), it uses that context to pull relevant structures, persuasive language, and standard sections. It's not just filling blanks; it's constructing a tailored document based on proven frameworks for your field.

Is the e-signature legally binding?

Yes. The e-signatures collected through SoloTools are legally binding and compliant with major e-signature laws like the ESIGN Act in the U.S. and eIDAS in the EU. The platform creates a secure, timestamped audit trail for each signature event, which can be used as evidence of agreement. For critical contracts, we always recommend consulting with a legal professional.

What happens if my client doesn't sign before the expiry date?

When you set a "Valid until" date, the proposal automatically locks and becomes un-signable once that date passes. This creates a gentle urgency for the client. You can always duplicate the expired proposal, update any details if necessary (like timelines or pricing), and send a fresh, new version to re-engage the client and restart the process.

Can I use my own branding on proposals?

Absolutely, but this is a feature of the Pro plan. With a Pro subscription, you can upload your company logo, set your brand colors, and even add custom footer text. This ensures every proposal you send is consistently branded, looks incredibly professional, and reinforces your business identity, making you stand out from competitors using generic formats.
