Size up the problem before you build anything.
Quick calculators, demos, and templates I use with clients on discovery calls. No email gate — use them, save them, share them.
AI Agent Builder Demo
Sketch a multi-step AI agent in your browser, then test it against the arithmetic that decides whether it survives production: per-step reliability, retries, and how many boxes you can afford to add.
AI Automation Consultant
Chat with an AI automation consultant and get a prioritised strategy for your business
AI Chatbot Builder Demo
Configure a custom AI chatbot, feed it your own FAQs and product information, and have a live conversation with it in the browser — no code and no sign-up.
AI Knowledge Base Generator
Turn any document, FAQ, or email log into a structured AI knowledge base instantly
AI Outreach Message Generator
Generate personalised cold outreach emails and multi-touch follow-up sequences, with a worked rewrite showing what makes a cold email answerable and a note on UK and EU compliance.
AI Voice Agent Cost Simulator
Work out what an AI voice agent costs before you build it. Add up infrastructure, text to speech, the language model, telephony and add-ons per minute, then multiply by your real call volume, and see where the estimate and the invoice diverge.
Prompt Library & Tester
Test and iterate on AI prompts until the output is consistent enough for production. Includes a worked before-and-after rewrite, structured-output tips and the failure modes that only appear at scale.
RPA Script Generator
Describe any manual process in plain English and get a working first-draft automation script for UiPath, Power Automate, Automation Anywhere or Python.
SOP to Automation Generator
Paste a Standard Operating Procedure and get a step-by-step automation blueprint — which steps can be automated, which need a human, and which platform suits each one.
.env Manager
Validate environment variable names and values before they reach production. Env Manager checks names against POSIX rules, flags values that different .env parsers read differently, and shows which entries are secrets that should not sit in a file.
.gitignore Generator
Build a .gitignore for your stack in seconds. Covers dependencies, build output, IDE files and the .env patterns that keep secrets out of a public repository.
API Mock Server
Create a live mock REST endpoint with your own path, method, status code, headers, delay and JSON body — so you can build and test a frontend or automation before the real API is ready.
API Request Tester
Send REST API requests from your browser with custom headers, auth and a JSON body, and inspect the status, headers and response. Includes a guide to reading status codes and diagnosing CORS.
Base64 Encoder
Convert text, JSON or files to Base64 in the browser, with nothing sent to a server. Covers the padding rules, the exact 33% size increase, and the non-canonical strings that decode to identical bytes.
Cron Expression Generator
Build cron expressions visually and get the correct string for crontab, GitHub Actions, EventBridge, Kubernetes, Make or n8n — with a field reference and the common gotchas explained.
Cron Timezone Converter
Convert a cron expression between timezones and see the next run times in both. Handles daylight saving properly, so a schedule set in London does not silently drift by an hour on a UTC server.
cURL to n8n Node Converter
Convert a cURL command into an n8n HTTP Request node you can paste straight onto the canvas, with JavaScript fetch and Python requests equivalents generated at the same time. Runs entirely in your browser.
Docker Compose Generator
Build a complete docker-compose.yml for any stack in seconds — with health checks included
Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-512 and HMAC digests in the browser. Includes a reproducible webhook signature example and why re-serialised JSON never matches the sender's signature.
JSON Formatter
Format, beautify and minify JSON in the browser. Paste a raw API response or webhook payload and get indented output plus the exact line and character of any syntax error.
JSON Validator
Validate JSON syntax in the browser and get the exact character position of any error, plus a plain explanation of what syntax checking can and cannot catch before data reaches production.
JWT Decoder
Decode a JSON Web Token in your browser and read its header, claims and expiry. Built for debugging auth failures, with guidance on what decoding does not prove.
n8n Workflow JSON Sanitiser
Strip API keys, tokens, webhook URLs and credential references out of an n8n or Make.com workflow export before you share it. Flags every secret it finds and produces a clean, still-importable JSON file. Runs in your browser.
OpenAPI Validator
Validate an OpenAPI 3.x or Swagger 2.0 specification in JSON or YAML. Catches schema errors, unresolved $refs and missing required fields before they break code generation or a gateway import.
Regex Tester
Write and test regular expressions against your own sample data with live match highlighting and separated capture groups, plus the backtracking pitfalls that turn a working pattern into a hung process.
SQL Formatter
Format any SQL query into clean, indented, readable output in your browser. Nothing is uploaded. Includes a worked example showing how a misplaced LEFT JOIN filter silently drops rows.
URL Encoder/Decoder
Percent-encode or decode URLs, query strings and Unicode. The page below compares what encodeURIComponent, URLSearchParams and Python's quote and quote_plus actually produce, because all four disagree.
Webhook Signature Verifier
Check a Stripe, GitHub, Shopify, Slack or Twilio webhook signature against the raw body and signing secret, and see exactly why it fails. Computes real HMAC in the browser using the Web Crypto API.
YAML / TOML / JSON Converter
Free browser-based converter between YAML, TOML and JSON. Shows you the values that change shape during conversion rather than quietly rewriting your config.
Agency Retainer Calculator
Work out what a retainer needs to be to hit a target margin. Accounts for delivery hours, software costs, scope creep, non-billable time and the effective hourly rate you end up with once everything is counted.

Estimate what an AI agent really costs to build and run each month — model usage, platform fees, development time and maintenance — with a worked example and the metered costs most quotes leave out.
AI Receptionist Cost Calculator
Compare the monthly cost of a human receptionist against an AI voice agent handling the same call volume, including out-of-hours cover, holiday and the calls a person cannot answer while already on a call.

Missed Call Revenue Calculator
See exactly how much revenue missed calls are costing your business every month

Free automation project cost calculator. Splits build, subscriptions and maintenance, and shows you how to uplift an optimistic estimate using the UK Treasury method.
Proposal / Quote Template Generator
Build reusable proposal templates you can fill in and send in under 10 minutes, with UK statutory payment terms and an IP clause that transfers copyright rather than assuming it.
Proposal Generator
Generate a structured client proposal from the brief, the scope and the price, then run the review pass that catches the two things every generated proposal gets wrong: an unstated VAT position and a cost-of-inaction figure with no source behind it.

Sales Process Analyzer
Map your sales funnel and find every step where automation would win you more deals
