I build tools because I got tired of the alternative. Renting a dozen apps, paying monthly for features I never touched, and still not finding the one that did the simple thing I needed. More than half of paid software seats (53 percent) sit unused every month, quietly renewing on someone's card. That math never sat right with me.
So I started making small, browser-based tools I actually wanted. You buy them once, you own them, they work offline, and nothing renews. Here is the whole lineup on my site: what each one does, and how it helps. They run from 2 dollars to 39 dollars, and several of them use AI to do the heavy lifting.
None of this is theoretical. Every tool here started as a problem I hit in my own week. I built the ugly first version for myself, then cleaned it up enough to share. That is also why they are cheap: I would rather sell a lot of simple tools that actually get used than one expensive thing that sits in a forgotten browser tab.
AI & Marketing: Get Seen, Get Cited, Get Clicked
This is the set I reach for to get found (in search, in AI answers, and in the feed) and to turn attention into something that lands. If you only grab from one category, I would start here, because visibility is usually the thing quietly costing you the most.
- The Power-User Prompt Kit (free + $19): 47 pro AI prompts in a searchable library. It kills the blank-ChatGPT-box stare and gets you usable output in seconds. The first 12 are free, so you can try before you buy.
- AEO Prompt Vault ($24): 54 prompts to check whether ChatGPT, Gemini, and Perplexity already mention your business, spot the gaps, and get cited. It helps you show up in AI answers, not just Google.
- SERP Snippet Optimizer ($19): write title tags and meta descriptions that fit Google and actually get clicked, with a real pixel-width preview. It helps more people click your result instead of scrolling past it.
- Content & Social Media Planner ($19): plan a month of posts across every channel in calendar, list, and board views. It helps you stay consistent without the Sunday-night scramble.
- Work Smarter AI Business Kit ($29): 4 guides, interactive workbooks, and 12 reusable prompts. It helps you put AI to work across your whole business, not just one task at a time.
Money: Know Your Numbers, Get Paid
The money side of running a thing, minus the spreadsheet you dread opening. These are the ones that pay for themselves the fastest, usually the first time you send a clean invoice or catch a quote you were about to underprice.
- The Client Cashflow Kit ($29): Quote, Proposal, and Invoice in one get-paid workflow. It helps you go from "yes" to "paid" without juggling three separate tools.
- Cash Flow Forecaster ($18): see what is coming in and when you will be short, before it hits. It helps you stop being blindsided by a slow month.
- Quote & Profit Builder ($12): know your real take-home on a quote after fees, overhead, and taxes. It helps you stop accidentally underpricing your own work.
- Invoice & Payments Studio ($9): professional invoices in seconds, exported as a real PDF. It helps you look polished and get paid faster.
- Freelance Expense & Tax Tracker ($19): always know what to set aside for taxes, and export it CSV-ready for your accountant. It helps you skip the tax-season panic.
Business & Admin: From Idea to Paid
The unglamorous backbone that turns a side idea into a real one. This is the paperwork and project side: boring right up until it is the exact reason you got paid or kept your week from falling apart.
- TaskFlow ($19): everything you are juggling in one place, with List, Board, Timeline, and Calendar views. It helps you stop dropping balls across sticky notes and three different apps. I did a full breakdown of task trackers if you want the comparison.
- Business Owner's Bundle ($39): the Client Cashflow Kit plus the Business Starter Kit, four tools bundled. It helps you grab the whole plan-it-and-get-paid stack for less.
- Business Starter Kit ($14): turn your idea into a real one-page business plan. It helps you get it out of your head and onto a page you can act on.
- Proposal Builder ($9): send branded client proposals that win the job. It helps you look legit and close more of the work you pitch.
Career & Life: The Everyday Ones
Little tools for the rest of it, because not everything has to be about work. Running a business is still a life, and these are the small ones that make the non-work parts a little easier too.
- Quick Résumé Builder ($14): a clean résumé in minutes, with a strong-verb helper built in.
- Focus & Flow Pack ($24): an ADHD planner, brain dump, and daily game plan to turn overwhelm into momentum.
- Decision Dice ($2): add your options, weight the odds, and let it pick when you genuinely cannot.
- Meal Planner & Grocery List ($14): plan the week and it auto-builds your grocery list for you.
Why Mine Work Differently
Every tool here follows the same three rules: you buy it once, you own it, and it runs in your browser with no login and no monthly fee. Your data stays on your device. Nothing renews, nothing locks you out, and nothing quietly creeps up in price next year.
I built them for the version of me who was running several brands with no budget for enterprise software, and that is still exactly who they are for. Small, honest, and yours to keep.
There is no upsell waiting three screens in, no team seat you forgot to cancel, and no feature held hostage behind a higher tier. You pay once, you download it, and it is done. That is rare enough now that it almost feels like a gimmick, but it is really just how buying software used to work.
Start With One, Not All of Them
You do not need the whole shelf. Pick the single tool that fixes the thing annoying you this week, use it, and come back when the next bottleneck shows up. Most people start with the Prompt Kit or the Client Cashflow Kit and build from there. The point is momentum, not a software collection.
You can browse the whole lineup, with covers and quick previews, on my Tools and Resources page. Grab whatever solves this week's problem and happily ignore the rest.
