The problem, stated plainly
A calorie calculator you use twice a week. An AI writer you use in bursts, then not at all for a fortnight. A SERP preview tool you open maybe four times a month. A proposal template generator you need only when a client says yes.
Individually, none of them justifies $19 a month. Together they cost more than the work they save. And every one of them wants its own login, its own billing date, its own cancellation flow you have to remember to use.
ToolkitPlan is the other arrangement: one wallet, one login, and a shelf of small tools that each cost a few credits to run. A quiet month costs you a quiet month’s worth. A heavy month, you top up.
Who builds it
ToolkitPlan is built by a solo developer with 15+ years of experience — custom plugins, front-end work, and a portfolio of content sites run and maintained independently.
Those sites are where these tools come from. The fitness calculators were built for a health site and refined against real traffic. The SEO and revenue tools were built out of a need for them in day-to-day publishing work, when nothing off the shelf did quite the right thing. ToolkitPlan is what happens when tools built for one person’s own use turn out to be good enough to hand to other people, under one price.
There is no team, no investors, and no growth board. That’s the honest version, and it has consequences worth knowing: replies come from the person who built the tool, not a ticket queue; the roadmap moves at the speed of one developer; and nobody is going to acquire this and shut it down next quarter.
How we decide things
- You see the price before you spend. Every tool shows its credit cost up front. No surprise metering, no “fair use” clause that quietly means a cap.
- A failed run costs nothing. If a tool errors, the credits go straight back to your wallet automatically. You shouldn’t have to open a support ticket to get back what you never received.
- Free means free, not a countdown. Thirty credits at signup, no card, no fourteen-day timer pressuring you into a decision.
- Your work isn’t training data. What you put into these tools is used to answer your request and nothing else. It’s never sold and never fed into model training.
- Canceling is one click. In the dashboard, where you’d expect it. No email, no exit survey, no offer designed to wear you down.
- Need more than a standard plan? Custom features, integrations, and priority handling are available as paid support, quoted separately — get in touch.
What’s on the shelf
Four categories, all drawing from the same balance:
- Fitness & nutrition — BMR across five formulas, keto macro splits, fasting windows, deficit planning, meal planning.
- SEO & publishing — SERP previews, content decay checks, AI API cost estimates, affiliate and RPM forecasting.
- AI writing — blog drafts, product descriptions, ad copy, cold email sequences, bulk social captions.
- Business documents — proposals, scopes of work, agreements, client-facing letters.
New tools get added regularly, and they cost the same credits as everything else. You don’t pay again for the shelf getting longer.
Where it’s going
The plan is more tools, not more tiers. Team wallets with shared balances, saved presets so you can re-run a tool with the same settings, and an API for people who want to call the tools from their own systems. If you want something on that list, say so — a single-developer roadmap is unusually easy to influence.
