SoloTools
AI-Powered Proposal Generation
This isn't just a dumb template filler. You give it the basic project ingredients, and the AI writes the whole meal - a compelling executive summary, detailed scope breakdowns, professional pricing tables, and persuasive terms, all tailored to your specific gig. It does the heavy lifting so you don't have to sound like a robot copying from your last proposal. It generates the full, polished doc in about 12 seconds, turning your few words into client-ready gold.
Smart AI Editing & Refinement
Stuck on a section? No sweat. SoloTools lets you tweak the AI's writing on the fly with simple commands. Just tell it to "Make this more persuasive," "Make it shorter," "Add more detail," or "Rewrite in a formal tone" for any specific part of the proposal. It's like having an editor in your pocket that instantly refines your text to hit the right note, saving you from the frustration of rewording things yourself.
Built-in E-Signatures & Tracking
Go from "sent" to "signed" without the annoying chase. Send proposals directly via email from the platform and then track when the client opens it (you get a notification!). They can sign it right there with a canvas e-signature, accepting or even declining with a reason. You can also set expiry dates to create urgency and automatic follow-up reminders, so you never have to send that awkward "just checking in" email again.
Proposal Analytics & Insights
Wanna know what's working? The analytics dashboard shows you your entire conversion funnel - how many proposals you sent, were viewed, and were accepted or declined. See your win rate and average close time. It helps you spot where you're losing deals so you can tweak your approach. Plus, with real-time view notifications, you know the exact moment a client opens your doc, so you can follow up at the perfect time.
