Free tools that stay in your browser.
Most free online tools are broken on purpose. They demand an account before showing you anything. They quietly upload your resume or your document to a server you know nothing about. They watermark the output, cap you at three uses a day, and slide in a paywall the moment the result starts looking useful.
Swiftly.tools is the counter-argument. It is a collection of 21 everyday tools - AI prompt builders, an ATS resume checker, an invoice generator, a PDF merger, and more - that run entirely in your browser, cost nothing, and ask for nothing in return.
Other sites ask you to trust a privacy policy. We removed the need for trust altogether. Every tool on this site processes your data locally, in your browser: your resume, your prompts, your PDFs, your invoices. They never travel to a server, because there is no server-side step to travel to. Do not take our word for it - open the network tab in your browser's developer tools while using any tool and watch. Nothing is sent.
Most tool sites wrap a 20-line script in a pretty interface. We build tools like small products. The AI Prompt Builder, for example, runs your input past three independent agents - an Architect, an Optimizer, and an Evaluator - that critique each other and score the result across six metrics. A lazy one-line input earns an honest 40, not a flattering 75. The tool then coaches you, suggestion by suggestion, until the prompt genuinely deserves the score it finally hands back.
No accounts. No locked pro tier. No watermarks, no daily limits, no checkout page appearing at the worst possible moment. The site is paid for by unobtrusive advertising - that is the entire business model, and it is stated here plainly so there is never any confusion about it.
