Certification and interview preparation · examness.com
A learning platform for developers and IT professionals that covers both gates of a technology career. It combines four things that usually live on four separate sites: exam-style certification practice with explanations and timed mocks, an interview question bank of more than 3,200 answers across thirty-odd topics, a Code Lab that executes in your own browser, and AI teachers grounded in your actual history.
The pricing idea in one line: everything is free except the AI. Reading, practising and running code never spend a credit.
- Wrong answers are stored deliberately, and the AI teacher reads them before it replies
- Timed mock exams with per-domain breakdown, plus generated study plans and a readiness estimate
- Code Lab: let the AI draft a solution, stop it mid-line, and finish the function yourself
- Arcade-style revision games, discussion threads on every question, and a dashboard that ties it together
- English, Hindi, Bengali, Japanese and Indonesian · web, Android and iOS
Automated QA and security analyst · provelex.com
An automated tester that works the way a careful person would, without ever getting bored. Point it at your application, prove the target is yours, add a login, and tick the suites you want. It opens a real browser, works out what the software does, tries to break it, and writes the result up for somebody who has to approve the fix rather than perform it.
There is no framework to learn. No scripts, no selectors, no YAML — a renamed control produces a heal event, not a red build.
- Five suites per run: functionality, security, performance, accessibility and mobile view
- Security probes are bounded and non-destructive, mapped to the OWASP Top 10 (2021)
- Ownership must be proven before anything active runs, and the signed grant is printed in every report
- A published score formula, drift against the previous run, and evidence behind every claim
- Web, Windows and macOS · white-labelled PDF, HTML and JSON exports · CLI and HTTP interface
Emotion-aware ad decisioning and ad studio
An advertising agency that runs on a database query. Adotopia reads a film or a script scene by scene, builds an emotional twin of it, then places an advert where the mood actually fits — and never beside a death, a climax or a scene somebody is crying through.
- Per-scene emotion vectors in PostgreSQL with pgvector; matching an ad to a slot is one similarity query
- Brand-safety adjacency guard: congruent mood and a natural narrative break, or no placement at all
- Generates the ad video itself, and lays on-screen messages where they do not cover the picture
- Also makes static ads for newspapers and websites, in English, Hindi and Bengali
Multilingual AI voice receptionist
The phone rings while you are with a customer, so it goes unanswered and the lead is gone. Voicotopia picks up in the caller's own language, books or reschedules the appointment, and messages them afterwards — set up by somebody who has never written a line of code.
- Answers in English, Hindi or Bengali, and reports back to the owner in English
- Never invents: it may quote a price or policy only from knowledge the owner approved, or it says it does not know
- Never drops a lead — a provider outage, a silent caller, a failed transfer all end in a callback task
- Books, reschedules, cancels, transfers and follows up over WhatsApp or SMS
