Eleven tools for people preparing for Indian competitive exams — PDFs, images, a 3D atlas, a graphing calculator and a mind-map builder. Every one of them runs inside your own browser: your files are never uploaded to a server, not even for a moment.
Most of the tools here finish a job in a few seconds. Three of them are full applications, and each opens in its own window.
A globe you can actually question. Type a name — a country, a river, a desert, a mountain range, a sea — and the Earth turns to it. Borders, capitals and physical features are all there, you can draw and label directly on the surface, and the whole view exports as a PDF.
Type a function and watch it draw. Roots, turning points, inflection points and intersections are found for you, areas under a curve are computed, and you can mark points and measure the distance between them. Export as PNG or PDF straight into your notes.
A canvas for the topics that only make sense once you can see them laid out. Add nodes, join them with curved arrows, change shapes, colours, fonts and backgrounds, drop in images, and let auto-layout tidy the whole thing with one click.
Every year, applications to SSC, UPSC, NEET, JEE, IBPS, RRB and the state commissions are rejected over the photo and signature upload rather than anything to do with eligibility. The Image Resizer sets exact pixel dimensions and a target file size, and Compress PDF brings a scanned document under a portal's limit.
Every exam sets its own dimensions and size limits, and they change from year to year. Take the exact numbers from the official notification or the upload page itself, then use the resizer to hit them precisely.
CogniSwift is a revision engine. Paste your notes or upload a PDF and it writes the flashcards, the structured summary and the self-test quiz for you — then runs the most advanced revision scheduling system available anywhere on top of them, calculating card by card the exact day each one should come back to you.
It builds a model of how you personally forget, so no two people get the same timetable. Set your exam date and the whole schedule bends towards it: intervals tighten as the day approaches, so your recall is at its sharpest in the exam hall rather than three weeks before it.
These document tools sit alongside it because every aspirant needs them at some point, and they cost nothing to run on your own device. No account, nothing uploaded, no watermark.
