How to use MiniToolkit
Tiny AI tools that just work. Pay cents per run. No subscription. Here's everything you need.
What MiniToolkit is
MiniToolkit is a collection of single-purpose AI tools. Every tool is one form, one prompt, one result — no chat, no setup, no fiddling. You pay a few cents per run instead of $20/month for a chat assistant you might not use.
The pitch is simple: when you have a recurring task — apologize for a missed deadline, write a tight resume bullet, summarize a meeting — a purpose-built tool produces a better result faster than rephrasing the same thing into ChatGPT every time.
Getting started
- Visit the marketplace and pick any tool.
- To save your work and run any tool, sign in: hit Sign in, type your email, click the link we send.
- New accounts get 10 free credits on first sign-in — enough to try a handful of tools at average pricing.
How credits work
Each tool tells you up front how many credits a run costs. Most tools are 1–3 credits. Heavier tools that produce long-form output (like Customer Interview Synthesizer) are 4–5.
Top up
Buy credits at /me/buy in three pack sizes:
- Starter — $9 → 100 credits ($0.09/credit)
- Pro — $20 → 250 credits ($0.08/credit)
- Power — $50 → 750 credits ($0.067/credit, ~33% bonus)
Credits never expire. Your balance shows in the top-right of every page.
Refunds
If a tool fails because the model errors or the form data is invalid, your credits are refunded automatically — you'll see a `refund` line in your activity log. If you ever feel charged unfairly, email support@minitoolkits.com.
Free runs
Tool authors can choose to sponsor their tool's runs on third-party sites — meaning the visitor doesn't pay, the author does. So you may run into tools embedded on blogs that are free for you.
Your dock
Pin tools you use often to your dock. Hit the 📍 Pin button on any tool's detail page or its card on the marketplace. Pinned tools show up first in your dock, in the browser extension, and in the Slack tool picker.
The dock is your home base — bookmark /d instead of memorizing tool URLs.
Use tools anywhere
The website is one surface. There are four more:
Slack
Install the MiniToolkit Slack app once per workspace. Then type /mtk in any channel to pick a tool, or /mtk <tool> <input> to run inline. Result is DM'd to you.
Browser extension
Highlight any text on any webpage → right-click → MiniToolkit → pick a pinned tool → output is copied to your clipboard. Get it from the docs (currently developer install).
Inside Claude / Cursor / agents (MCP)
Mint an API key at /me/api and add MiniToolkit as an MCP server in your Claude Desktop or Cursor config. Your tools become callable from those agents. Setup details.
Embedded on websites
Creators can drop their tools into blogs, Substacks, and product landing pages as a Web Component (<mtk-tool>). When a tool is sponsored by its author, you can use it without an account.
Privacy
What we never do: use your inputs or outputs for training, share your runs with other users, sell your data, show your runs to anyone but you.
What we save
- Your run history. The inputs you provided and the output you got, attached to your account. Visible only to you, on /me/history. Delete any saved run with one click — the text is wiped from the database immediately and only the metadata (which tool, when, how many credits) stays for billing audit.
- Your account basics. Email address, sign-in sessions, credit balance, ledger entries, pinned tools. Required to operate the service.
- Aggregate run logs. Tool slug, token counts, IP, timestamp — for billing, abuse prevention, and rate limiting. We retain these even after you delete a run's text.
- Stripe records. Payments are processed by Stripe; we keep transaction IDs but never see your card number.
Where your inputs go during a run
Your input is sent to the AI model provider (Anthropic) over an encrypted connection to generate the output, then both are saved to your private history. Anthropic processes the request under their published commercial terms and does not train on API traffic. We do not send your inputs to any other third party.
Sensitive content
Use the same judgment you would with any AI tool: don't paste material (PII, customer data, trade secrets, regulated documents) that you wouldn't be comfortable storing in your private history. If you paste something sensitive by accident, delete the run from /me/history and it's gone.
Account deletion
Email support@minitoolkits.com to delete your account. We remove your email, sessions, run history, ledger entries, and pinned tools. We retain anonymized billing audit records (transaction date + amount, no inputs/outputs) for the time required by tax and accounting law.
Suggest a tool Coming soon
If you have an idea for a tool that doesn't exist yet, email us at support@minitoolkits.com. We're adding new tools every week based on what people are asking for.
A self-serve creator program is on the roadmap — details when it's closer.
FAQ
Why pay-per-run instead of a subscription?
Most people use AI tools sporadically. A $0.20 run is a no-brainer; $20/mo for occasional use isn't. We charge actual usage, not anticipated usage.
Which AI model does MiniToolkit use?
Claude Haiku 4.5 by default — fast, cheap, smart enough for focused single-shot tasks. Some heavy tools use Sonnet when needed. Tool authors can choose.
Is there a mobile app?
Not yet. The website works fine on mobile. A native app is on the roadmap.
What if I find a tool that produces bad output?
Run it once and let us know — we'll work with the creator to tighten the prompt, or remove the tool if it's broken. Your run that produced bad output gets refunded.
How do I contact you?
Email support@minitoolkits.com. We answer.
Integrating with the API?
REST endpoints, MCP server setup, embed widget, Slack integration.
