Three AI tools. Free, and actually useful.
We built these with the same stack we teach — Workers AI, structured prompting and a bit of care about failure modes. They run live on this page. Use them before you decide anything about us, including whether to talk to us at all.
Try it yourself
Pick one and start.
Each one opens right here. Nothing is emailed to you, and nothing is behind a form until there is a file to hand over.
What each one does
And what it will not do.
The profile check
You describe your background in plain words — degree, marks, work, gaps, what you know. It comes back with two AI roles that are realistically reachable, three specific gaps in your way, a package range and a timeline.
It is tuned to be honest rather than flattering. If your background is thin for the role you want, it says so.
The mock interview
Pick the role you are aiming at and answer five questions the way you would in the room. You get feedback and a score after every answer, then a verdict: your level, your biggest gap, and what to study next.
It marks strictly. A score you are unhappy with here is cheaper than the same result in a real interview.
The resume builder
Upload your current resume and it is read in your browser, sorted into sections, and rewritten for the AI role you name. Or start from an empty form. Three templates, and you leave with a PDF to apply with and a Word file you can keep editing.
It rewrites what you give it. It will not invent a job, a metric or a technology you never touched — read every line before you send it.
A note on how these work
Where your data goes.
Worth saying plainly, because most sites do not. When you upload a resume, the file is read in your browser — it is never uploaded to us. Only the extracted text is sent to the AI model to be sorted into sections, and we do not keep it.
The finished PDF and Word file are built in your browser too, which is why the download is instant and works even on a slow connection.
The one thing we do keep is what you type into the contact box before downloading: your name, phone and email, so the placement team can flag openings that match. That is the trade, and it is the only one.
The microphone buttons use your browser's own speech engine. They work in Chrome, Edge and Safari, and will not appear at all in Firefox, which has no support for it.
Liked the tools? The course is the same thinking.
Everything on this page was built with what we teach in the program — structured prompting, retrieval, evaluation and a stubborn focus on what happens when the model gets it wrong.
