Marketing Agency Tools for Ad Headlines, Creative and Video Captions

Score a headline out of 100 before it goes in the ad set, resize and watermark a whole batch of creative, and burn translated captions into your client videos.
 

You know the drill. The strategy call went great. The client loved the plan. Everybody’s excited about the new campaign.

Then the real work starts. Twelve headline variants. The same static ad in five sizes. A webinar replay that needs captions (in Spanish too, please). Logo bug on every clip. A list to split for the A/B test. And the client report is due Friday.

None of that is strategy. It’s production grunt work, and on a flat retainer every hour of it comes straight out of your margin. Sound familiar? ❓

Here’s the thing: Ads Manager, Google Analytics and your email platform aren’t the problem. It’s all the little stuff you do around them, by hand, for every client. That’s exactly the kind of work a computer should be doing for you.

So below are the tools I’d hand any marketer or agency, most helpful first. Some run on your Windows PC, some run right in your browser. None of them need you to learn anything techy. Click Learn more or Try it on any one for the full rundown.

Now on with the show… 😃

Headlines, Hooks and Ad Copy ✍️

Creative gets the scroll to stop. The hook decides whether anybody reads on.

ToolWhat it does for you
ScoreMyCopy
Learn more →
Paste your headline or hook, describe your audience, click Score. It grades it out of 100 using principles from Hopkins, Ogilvy, Caples, Schwartz and Halbert, then Auto Improve keeps rewriting until it hits the score you set. Great ammo when the client wants to argue about the headline. 😊 (It scores the copy. Your split test still gets the final vote.)
PromptImprover
Learn more →
Highlight your rough ChatGPT or Claude request anywhere on your PC, press Ctrl+Shift+P, and a clear, detailed prompt lands on your clipboard. Better brief in, better first drafts of ad variants and email sequences out.
Noticeable Text
Learn more →
Browser version →
Bold, script or circled text for LinkedIn, Instagram, X and Facebook posts, where there’s no font picker. It’s real Unicode characters, so the style survives the paste. Use it sparingly on the one line you want read.
Tip: Write five hooks, score all five, and only test the top two. Your ad budget goes to the strongest contenders, and you have a score to show the client for why you picked them.
Creative Assets: Every Size, Every Format 🎨

One concept, twelve placements. Here’s how to stop hand-sizing the same asset over and over.

ToolWhat it does for you
ImageCreator
Learn more →
Browser version →
Describe the ad background or concept image, then fix it by talking to it: “make the lighting warmer, remove the car.” It changes only that part and leaves the rest alone. Great for mood boards and concept rounds before the shoot. 🤖
Image Size Reducer
Learn more →
Browser version →
Point it at a folder of creative and every image shrinks to the max size you pick, shape kept, originals safe. The browser version can also target a max file size for upload forms and email templates with weight limits.
Image Converter
Learn more →
PNG to WEBP for page speed, real SVG rendering, multi-size ICO favicons for the client’s site. Drag, drop, done. The converted files land right next to the originals.
Watermarker
Try it →
Stamp the client’s logo (or “DRAFT”) on a batch of photos. Handy for proofs you send before the invoice is paid. 😉
VideoCreator
Try it →
Type a sentence, get a short AI video clip with sound. Queue several concept clips for a Reels or TikTok test and walk away. Bring your own OpenRouter key.
Canva Hotkeys
Learn more →

Video for Social and Paid: Captions, Branding, Repurposing 🎬

Most social video gets watched with the sound off. And every client wants their logo on it.

ToolWhat it does for you
Translate and Subtitle Video
Learn more →
Point it at a video, pick a language, and it transcribes, translates, builds the SRT and burns the captions right into the video (or embeds them as a track). Powered by OpenAI and FFmpeg. Captions for the sound-off crowd, plus a Spanish version for the client who asked.
Video Sandwicher
Learn more →
Drop in a batch of clips and it adds your branded intro and outro to every one, with fades. A week of client videos, branded in one go.
WaterMarker (video)
Learn more →
Put the client’s logo bug on a video exactly where you want it. You drag it around on a real frame from the video, set the opacity, and render. What you see is what lands in the final file.
Video Progress Bar
Learn more →
Add a YouTube-style progress bar to any video, top or bottom, in the brand colors. That thin bar tells viewers exactly how much is left before the CTA. Your original video isn’t touched.
Effortless Video Reducer
Learn more →
Final cut too big to email the client for approval? Drag, drop, done. It shrinks way down without you touching a single encoding setting.
ClipGrabber
Try it →
Trim the webinar replay down to the one great 45-second answer and save just that piece. Instant repurposing material, right in your browser.
VideoToGif
Try it →
Turn a few seconds of a video into a looping GIF. Perfect for email, where video doesn’t play but GIFs do.
VideoMerger
Try it →

FlipVideo
Try it →
Customer sent a sideways phone clip for the testimonial ad? Rotate or mirror it so it plays the right way up.
YT Downloader
Learn more →
Copy a YouTube link and grab the video, the MP3 or the transcript. Great for turning your client’s own webinars and YouTube videos into blog posts, clips and email content. (Stick to videos you or your client own.)
Tip: Repurposing combo: grab the transcript of the client’s webinar with YT Downloader, cut the best answer with ClipGrabber, burn in captions with Translate and Subtitle Video, and add the intro and outro with Video Sandwicher. One webinar, a week of social posts. ⚡
Lists, Email and Lead Capture 📋

The list is where the money is. These handle the tedious parts of building it, splitting it and following up.

ToolWhat it does for you
Randomize List
Learn more →
Need a clean A/B split? It shuffles a big list and splits it into as many random groups as you want, keeping the header row on every file. Control and variant, done without a formula.
DripCampaign
Try it →
Someone opts in for the lead magnet, and the nurture sequence goes out on its own, on schedule. Handy for a small client (or your own agency) that doesn’t need a big email platform.
QR Actions
Learn more →
Browser version →
QR codes that DO something on the phone: save a contact, draft a pre-filled email or text, add an event to the calendar, join Wi-Fi. Much more useful on a flyer, a booth banner or direct mail than a plain link. The Windows version runs 100% offline.
CardSnap
Try it →
Back from a trade show with a stack of business cards? Snap each one and get the name, company, phone and email as text, ready for the CRM.

Excel + Outlook Mail Merge
Learn more →
The script I use to pull Zoom webinar registrants and send personal follow-up emails through Outlook from an Excel list. It’s a script you’ll tweak for your setup, so it’s best for the marketer who likes to tinker.
YouTube Thumbnail to HTML
Learn more →
Featuring a video in the newsletter? It pulls the thumbnail and video info and gives you HTML to drop into the email.
Research and Reporting 📊
ToolWhat it does for you
FlexiFinder
Learn more →

Google Analytics Hotkeys
Learn more →
A sortable sheet of the built-in keyboard shortcuts for Google Analytics. Less clicking around the dashboard when you’re pulling numbers for the client report.
WordPress Hotkeys
Learn more →
Build landing pages and blog posts in WordPress? A sortable sheet of its built-in shortcuts for editing and managing the site.

One thing I’ve learned: you don’t need to automate your whole agency this week. Pick ONE deliverable on this list that eats your time on every client. Fix that. Then pick the next one.

An hour back per client per week adds up fast on a retainer. That’s more time for strategy, for testing, and for landing the next client. That’s the real FREEDOM.

How about you? What’s the one piece of production work you’d love to never do by hand again? Drop me a note and tell me. I read every one.
