Stop losing evenings to marketing. Contractor Marketing Lab is your AI marketing agent — it writes the posts, builds the images, and gets your next job locked in while you're still on the tools. Built for roofers, HVAC techs, plumbers, electricians, remodelers, landscapers, painters, concrete crews, window and door installers, and solar pros. No marketing degree required. No sitting at a laptop. Just real content from your real jobs, ready in seconds. Every morning you get a Daily Suggested Post, tailored to your trade and the season, ready to share the second you open the app. No blank page, no guessing what to post. Got a good story from today's job? Just talk. Use voice dictation to describe the work, and the AI turns it into a share-ready post with your voice, not some generic marketing tone. Every image comes branded automatically — your headshot, your logo, your phone number, your brand color, overlaid on real job-site style photos. It looks professional, and it looks like you, not a stock template. Need content fast without burning credits? Tap into the 500-piece preloaded library — 50 posts per trade, ready to brand and share, zero AI credits needed. Want to be the face of your business online? Use the talking-head video scripts, complete with hooks, CTAs, and simple filming tips so you look sharp on camera with zero experience. When you're ready to post, one tap does it all: image saved, caption copied, and the platform app opens — Facebook, Instagram, LinkedIn, X, TikTok, or Google Business Profile. Post in seconds, not evenings. Everything you create gets stored automatically in your Content Vault, so you can re-share your best posts, images, and scripts whenever you need them. Membership is $4.99 a month, with one-time AI credit packs available and free starter credits to get you going. The Keys to Your AI Marketing Agent — Locking in Your NEXT JOB.

Contractor Marketing Lab's advantage is update cadence (weekly vs every 6 weeks). On price, ads and device support there is nothing between them.
