About MySmartCoPilot | MySmartCoPilot

What MySmartCoPilot is

MySmartCoPilot is a collection of 798 free online tools for developers, designers, writers, students and small businesses in any country, plus 106 Pro and 15 Business tools that you can try free every day. Each one does one job well, without an account, a watermark or a sign-up wall. MySmartCoPilot brings everyday tools, business tools and AI help together in one place, and tutorials are on the way.

Wherever you are

Most tools do the same job in every country: merging a PDF, compressing a photo, formatting code, counting words or converting units does not depend on where you live.

Some tools follow the rules of a particular country or region, such as tax and pay calculators, legal documents and official codes. For example:

India

GST Calculator, Income Tax Calculator (Old vs New Regime) and PIN Code Finder (India Post)
United Kingdom

Stamp Duty & Registration Charges Calculator and Alcohol Units & Standard Drinks Calculator
United States

Overtime Calculator and Depreciation Calculator
European Union

Data Request (DSAR) Letter Generator
Gulf states

Gulf End-of-Service Gratuity Calculator

Others, such as the VAT Calculator (Add or Remove VAT) and the Historical Inflation Calculator (Any Country), are made for any country. Missing a tool for your country? Tell us which one.

How the tools work

Your browser downloads the page and the tool’s code from MySmartCoPilot, like any website.
You open a file or paste some text. Your browser processes it in its own memory, on your device.
The result appears on the page or is saved to your device as a download. Nothing you entered is sent to us.

That makes the tools quick, because nothing has to be uploaded, and private, because your files never leave your device. This is how 878 of the 919 tools work. 778 of the 919 tools also keep working without an internet connection once the page has loaded.

A few tools also use the network, but never to send what you enter:

World Clock: Only the optional “Is my clock right?” check uses the network: it sends six tiny header-only requests to this website and reads the time in the replies. They carry no cookies and nothing you typed.

41 tools work differently: to do their job, they send what you enter over the network, and each page says so:

Abuse Contact Finder : Your browser asks IANA’s bootstrap service, the regional internet registries, the domain’s registry and registrar (RDAP) and Cloudflare’s DNS resolver directly. Only lookups a browser cannot make are relayed through MySmartCoPilot’s server. MySmartCoPilot never sends a report.
APA Citation Generator (7th Edition) : Typing in the form works offline. Autofill sends only what you put in the autofill box: a DOI to doi.org (which forwards to Crossref, DataCite or another registration agency), an ISBN to Open Library, or a web address to MySmartCoPilot’s server, which reads that page.
Broken Link Checker : In “Page URL” mode the address is sent to MySmartCoPilot’s server, which fetches the page; the links found on it are then sent to the server in groups of ten, and it requests each one from its website and returns the status. With pasted HTML only the link addresses are sent.
Business Name Generator : The names are generated in your browser. Only if you press Check on a name are its domain names (such as brewcrew.com) sent to the domain registries’ public RDAP services — straight from your browser, not through MySmartCoPilot.
Chicago Citation Generator (18th Edition) : Typing in the form works offline. Autofill sends only what you put in the autofill box: a DOI to doi.org (which forwards to Crossref, DataCite or another registration agency), an ISBN to Open Library, or a web address to MySmartCoPilot’s server, which reads that page.
Citation Generator : The form works offline. Autofill sends only what you type into the autofill box: a DOI to doi.org (which forwards to Crossref, DataCite or another registration agency) or an ISBN to Open Library. Your bibliography stays in this browser.
DKIM Record Checker : Your browser asks Cloudflare’s DNS-over-HTTPS resolver for the key records (Google’s if Cloudflare cannot be reached); keys are decoded in your browser.
DMARC Record Checker : Your browser asks Cloudflare’s DNS-over-HTTPS resolver for the DMARC records (Google’s if Cloudflare cannot be reached); MySmartCoPilot’s servers are not involved.
DNS Lookup : Your browser sends each query straight to Cloudflare’s or Google’s DNS-over-HTTPS service; MySmartCoPilot’s servers never see what you look up.
DNS Propagation Checker : Your browser asks six public DNS-over-HTTPS resolvers directly (Cloudflare, Google, Quad9, AliDNS, Control D and CleanBrowsing); MySmartCoPilot’s servers are not involved.
Domain Availability Checker : Your browser asks Cloudflare’s DNS-over-HTTPS resolver, IANA and each registry’s RDAP service directly. Names under registries that block browser requests (such as .de) are asked through MySmartCoPilot’s server.
Harvard Referencing Generator : Typing in the form works offline. Autofill sends only what you put in the autofill box: a DOI to doi.org (which forwards to Crossref, DataCite or another registration agency), an ISBN to Open Library, or a web address to MySmartCoPilot’s server, which reads that page.
Historical Exchange Rates : Sends only the currencies and dates you choose to MySmartCoPilot’s server, which fetches the rates from the European Central Bank. The amount you type stays in your browser.
HTML / Web Table to CSV & Excel : Pasted content and opened files never leave your device. The Wikipedia tab asks Wikipedia for the article you name, straight from your browser. The Web page tab sends only the address to MySmartCoPilot, which fetches that page and returns the text of its tables.
HTTP Header Checker : In “Fetch a URL” mode the address you enter is sent to MySmartCoPilot’s server, which requests it from the website and returns the status and headers. In “Paste headers” mode nothing leaves your browser.
Indexability Checker : The URL you enter is sent to MySmartCoPilot’s server, which requests the page (following its redirects) and the robots.txt file of each host, and returns what the websites answered. The analysis runs in your browser.
Internet Speed Test : Runs the test against Cloudflare’s speed test servers (speed.cloudflare.com), which see your IP address and the test traffic. The results go to Cloudflare only if you tick “Share results with Cloudflare”; MySmartCoPilot receives nothing.
IP Address Lookup : Your browser asks the regional internet registry (RDAP), Cloudflare’s DNS-over-HTTPS resolver (for reverse DNS and Team Cymru’s routing data) and the Tor Project’s relay list about the address you enter. The country comes from a DB-IP data file on MySmartCoPilot itself.
Link Extractor : In “From a URL” mode the address is sent to MySmartCoPilot’s server, which fetches that one page and returns only its links. Pasted HTML is read in your browser and never uploaded.
MLA Citation Generator (9th Edition) : Typing in the form works offline. Autofill sends only what you put in the autofill box: a DOI to doi.org (which forwards to Crossref, DataCite or another registration agency), an ISBN to Open Library, or a web address to MySmartCoPilot’s server, which reads that page.
MX Lookup : Your browser asks Cloudflare’s DNS-over-HTTPS resolver for the MX, address and reverse-DNS records (Google’s if Cloudflare cannot be reached); MySmartCoPilot’s servers are not involved.
On-Page SEO Checker : In “Page URL” mode the address you enter is sent to MySmartCoPilot’s server, which fetches the page once and returns its HTML; the audit itself runs in your browser. In “Paste HTML” mode nothing leaves your browser.
Open Graph & Social Preview Checker : In “Page URL” mode the address is sent to MySmartCoPilot’s server, which fetches the page’s head and, if you leave it on, asks about the preview image (type, size, redirects). Your browser also loads the preview image from its own server to read its pixel size. In “Paste HTML” mode nothing is sent unless you tick the server image check.
Page Speed Test (Lighthouse via PageSpeed Insights) : Sends the address you enter (and the API key in use) straight from your browser to Google’s PageSpeed Insights API, which loads the page with Lighthouse. MySmartCoPilot’s servers are not involved and nothing is stored.
Pwned Password Checker : Your password never leaves your device. It is hashed with SHA-1 in your browser, and only the first 5 characters of that hash are sent to Have I Been Pwned’s Pwned Passwords API (api.pwnedpasswords.com), which returns every breached hash starting with them; the match is looked for on your device.
Redirect Checker : The URL you enter is sent to MySmartCoPilot’s server, which requests it (and each redirect target) from the website and returns the status codes and headers.
REST API Tester (Online API Client) : Your request goes directly from your browser to the API you enter — never through MySmartCoPilot. History and environments are kept only in this browser.
Robots.txt URL Tester : In “Fetch from a website” mode the site address is sent to MySmartCoPilot’s server, which downloads that site’s robots.txt and returns it. Pasted rules are tested in your browser and never uploaded.
Schema Markup Validator : In “Page URL” mode the address you enter is sent to MySmartCoPilot’s server, which fetches the page once and returns its HTML; the markup is read and checked in your browser. In “Paste code” mode nothing leaves your browser. The schema.org vocabulary the check uses is a file from MySmartCoPilot that loads the first time you check.
Security Headers Checker : Pasted headers are analysed in your browser and never uploaded. A URL check sends only the address to MySmartCoPilot’s server, which requests the page from the website and returns its response headers.
Speech to Text (Voice Typing) : Unless on-device recognition is available and in use (the page tells you), your browser sends your audio to its own speech service — Google in Chrome, Microsoft in Edge, Apple in Safari — to turn it into text. MySmartCoPilot never receives your audio or your text.
SPF Record Checker : Your browser asks Cloudflare’s DNS-over-HTTPS resolver for the SPF records (Google’s if Cloudflare cannot be reached); MySmartCoPilot’s servers are not involved.
SSL Certificate Checker : The host name is sent to MySmartCoPilot’s server, which connects to the site over HTTPS and HTTP and asks hstspreload.org for its preload status. Your browser searches crt.sh (Certificate Transparency) for the host name.
Suspicious Link Checker : The link is analysed in your browser and is never opened or fetched. Only if you press Look up domain age is the domain name (not the link) sent from your browser to IANA’s RDAP directory and to that domain’s registry.
URL Expander : The link is sent to MySmartCoPilot’s server, which follows its redirects with HEAD requests (GET only when a server refuses HEAD, without reading the page) and returns the addresses. Pages are never downloaded or shown.
Website Down Checker : The address is sent to MySmartCoPilot’s server, which requests it from Cloudflare’s network. With the browser test on, your browser also contacts the site directly so the two results can be compared.
Website Hosting Checker : Your browser asks Cloudflare’s DNS-over-HTTPS resolver (Google’s as a fallback) for the domain’s DNS records, and through it Team Cymru’s routing data for the site’s IP addresses. Countries come from a DB-IP data file on MySmartCoPilot itself.
WebSocket & SSE Tester : The page connects directly from your browser to the address you enter — never through MySmartCoPilot. Messages, headers and tokens are not stored; only the address (without its query string) and your settings are remembered in this browser.
What Is My IP Address : Reads your address from Cloudflare’s /cdn-cgi/trace on MySmartCoPilot’s own domain, checks the other IP version with icanhazip.com (run by Cloudflare) or ipify.org, and — only when you press the button — asks MySmartCoPilot’s server for the location details Cloudflare attaches to your request.
WHOIS Lookup (RDAP) : Your browser asks IANA’s bootstrap service and the official registry (and registrar) RDAP servers directly, and Cloudflare’s DNS resolver when a TLD has no RDAP service. Only registries that do not accept browser requests are asked through MySmartCoPilot’s server.
XML Sitemap Validator : With a URL, MySmartCoPilot’s server downloads the sitemap and your browser checks it. Uploaded or pasted sitemaps are checked in your browser and never sent — unless you press “Check status”, which sends up to 50 of the listed URLs to the server so it can request them.

The optional Ask MySmartCoPilot finder and the Developer API are different by design: there you send text to our server on purpose (see the privacy policy).

What we care about

Private by design

Almost every tool processes your files and text in your browser. We only count anonymous daily totals and keep what you choose to send us.
Honest

No fake reviews, ratings, user numbers or testimonials. Calculators explain the formula or rules they use, so you can check the result.
Built for everyone

We build every tool to work with a keyboard and screen readers, on small phones, and in light or dark mode.
Fast and light

Pages load only what they need. Heavy parts, like the PDF engine, load the moment you use them.

How MySmartCoPilot is funded

Most tools are free with no sign-up, and Pro and Business tools can be tried free every day. MySmartCoPilot runs on free hosting allowances, so keeping it online costs very little. To cover what it does cost and to pay for new tools, MySmartCoPilot sells optional passes for 1 week, 30 days or 1 year, one-time payments that never renew. Passes lift the daily limit of Pro tools (Business passes: of every tool), switch off ads and raise the limits of the server-side checks. MySmartCoPilot may also show:

ads from an advertising network, labelled Advertisements;
sponsorships, labelled Sponsored;
affiliate links that may earn a commission, labelled Affiliate link;
optional ways to support the site, labelled Support MySmartCoPilot.

Each of these is switched on only when a real advertiser, sponsor or partner is set up, and each is always labelled. The advertising disclosure and the affiliate disclosure show what is on right now.

Editorial independence

Advertisers, sponsors and affiliate partners do not decide which tools we build, how a tool calculates its results or what our guides say. Offers are matched to the topic of the page and are never placed inside tool results. Nobody can pay to change a result, buy a mention in a guide or move up our tool lists.

Accuracy and sources

Each tool is tested with known-correct examples and awkward inputs before it goes live. Finance and tax tools explain the formula or rules they follow, and 53 of them, such as the GST Calculator, the VAT Calculator (Add or Remove VAT), the Mortgage Calculator (PITI) and the Currency Converter, also link to the official laws, guidance or data they are based on. Mistakes can still happen, so please check important results (see the disclaimer) and tell us when something is wrong.

Suggest a tool or report a problem

New tools come from what people ask for. If you need one we do not have yet, or one of ours could work better, we would like to hear about it.
