What ToolBase is
ToolBase is a collection of free online utility tools — the kind that solve specific, everyday problems. Grammar checking, word counting, converting numbers to words, calculating age from a date of birth, figuring out days between dates, extracting data from screenshots. Small tasks that come up constantly and shouldn't require a subscription or a login to handle.
Every tool on the site is free to use without creating an account. There are no trial periods, no "5 free uses per month," and no premium version gating the features you actually need. The tools either work completely or they're not on the site.
Who we built this for
Honestly, we built it for ourselves first — and then realized the problems we kept running into were the same ones everyone faces.
Students who need to check grammar before submitting an essay but can't justify a monthly subscription. Professionals who need to quickly spell out a large number for a bank cheque. Freelancers who photograph invoices on their phone and need the data in a spreadsheet. Parents calculating their child's exact age for a school admission form. People who deal with Pakistani and Indian number formats (lakh, crore, arab) and constantly have to translate between those and the international million/billion system.
These aren't niche problems. They come up for millions of people every day, and the tools to solve them shouldn't cost anything.
How the site is supported
ToolBase shows Google ads. That's it. We don't sell your data, we don't have a SaaS business on the side, and we don't upsell to a paid plan. Ad revenue covers hosting and development costs and keeps all the tools free for everyone.
Most tools run entirely in your browser — your text, numbers, and images never leave your device. The Grammar Checker is the one exception: it sends your text to an external grammar analysis service to do its job. That service doesn't store your text. If you're working with sensitive information, use the other tools freely; just be aware of that distinction with the grammar checker.
The tools, briefly
- Grammar Checker — finds grammar, spelling and punctuation errors with color-coded highlights and one-click corrections. Supports English (US, UK, Australian), French, German, Spanish, Arabic and 25+ more languages.
- Plagiarism Checker — compare two texts for similarity, or check individual sentences against the web. Useful as a first pass before submitting academic work.
- Word Counter — live word count, character count, sentence count, reading time, and top keywords as you type.
- Number to Words — converts any number to correctly spelled English words. Covers both International format (million, billion) and South Asian format (lakh, crore, arab), with cheque wording for Pakistani Rupees.
- Age Calculator — exact age in years, months and days from any date of birth. Also shows total days lived, weeks, hours, and the next birthday countdown.
- Age Difference Calculator — the precise gap between two people's dates of birth, down to the day.
- Date Difference Calculator — days, weeks, months and years between any two dates, plus a business days count.
- Percentage Calculator — three modes: percentage of a number, what percent A is of B, and percentage change between two values.
- Screenshot to Document — upload any image of a table, receipt, invoice or result sheet and extract the data as CSV, JSON or plain text. Runs entirely in your browser; the image never leaves your device.
The blog
The blog covers practical topics connected to the tools — how to write numbers in words correctly, what lakh and crore mean and how to convert them, how plagiarism checkers actually work, what word count you should aim for in different types of writing, and similar questions that come up in everyday life. The posts are written to be useful references, not SEO filler.
