SoloTools vs TrackMailBox

SoloTools is an AI proposal generator built specifically for freelancers and independent consultants. Instead of staring at a blank document for hours, you describe your project in 30 seconds — client name, project type, budget, and a few scope notes — and AI generates a polished, client-ready proposal complete with an executive summary, scope of work, itemized pricing, timeline, and standard terms.
Every proposal is fully editable, downloadable as a PDF, and shareable via a branded link. The free plan includes 3 proposals per month. Pro ($14.99/month) unlocks unlimited proposals, custom branding, and proposal view analytics so you know exactly when a client opens your proposal.

TrackMailBox is a free and unlimited email tracking extension designed specifically for Gmail users. It addresses a common question among email senders: "Did they read it?" Unlike Gmail's default settings, which lack built-in read receipts, TrackMailBox provides a seamless solution for those who send important emails like proposals, pitches, or follow-ups. The tool eliminates the frustrations associated with other email tracking solutions that often impose restrictions, include unwanted signatures, or charge monthly fees. With TrackMailBox, you can track an unlimited number of emails without any branding, ensuring that your communications remain professional and clean. This extension is perfect for freelancers, sales teams, recruiters, job seekers, and founders—essentially anyone who relies on email for communication and wants to gain insights into their email engagement.
