AI gives everyone the answers.
We give you the structure.
AlgoInsight was built out of frustration - watching great engineers fail interviews not from lack of effort, but lack of structure. Content sites explain; nothing made you PERFORM. So we built the platform we wished existed: one place, three phases - Learn, Practice, and Interview - with an AI interviewer that talks back, keeps time, and scores every answer.

AI is everywhere.
But are you using it right?
Every candidate today has access to the same AI tools - ChatGPT, Copilot, Claude. Yet the interview pass rate at top tech companies hasn't changed. Why?
Because information is not preparation. AI can explain any algorithm in seconds. But it can't build your intuition, simulate the silence of a whiteboard round, or tell you exactly which part of your STAR response fell flat.
Ask anyone who has sat on the interviewer's side of the table and they'll describe the same pattern: smart candidates who consumed content for months but froze the moment a follow-up question landed. Not because they didn't know the material - because they had never practiced being questioned on it.
The problem was never access to information. The problem was structure.
Candidates who prepare for 3+ months
~70% still don't get offers
Candidates using AI for prep
Most use it like Google Search
What actually makes the difference
Structured, pressured practice
We got tired of watching great people fail interviews they deserved to pass.
Everyone knows the grind: LeetCode marathons without knowing if you're drilling the right problems. System design videos on 2x speed without ever designing anything under time pressure. STAR answers rehearsed alone in your head, with nobody to tell you they fall flat.
All that effort trains one skill - consuming content. But interviews test a completely different one: thinking out loud, under pressure, while someone probes every choice you make. No prep site made you practice that part. It was the gap nobody was closing.
So we did what engineers do: built the thing we wished existed - an AI interviewer that talks back, keeps score, and never lets hand-waving slide. Built nights and weekends, in public, shaped by every user who tries it.
It interviews you back
Voice on, timer running. The AI asks follow-ups, pushes back on weak reasoning, and goes quiet while you think - like a real panel.
Brutally honest scorecards
Every answer is scored dimension by dimension - correctness, structure, communication, depth - with the exact points where you lost marks.
No fake social proof
No invented testimonials, no imaginary team. The free demo interview IS the pitch - take it and judge the feedback yourself.
Built in public, shipped weekly
Early users talk directly to the builder. Feedback routinely turns into shipped improvements within days, not quarters.
One platform. Three stages.
This is the structure that separates candidates who get offers from candidates who almost do. We've built AI into every stage.
Learn
AI-structured knowledge, not information overload
Most candidates drown in content. We flip that. AlgoInsight's AI builds personalised quizzes from what you just read, speaks the content aloud if that's how you retain best, and flags your blind spots before you hit the practice stage.
- 30+ structured courses, most lessons narrated videos with animations built into the text
- AI generates adaptive quizzes targeting your actual weak areas
- Notes and highlights on every lesson, and a notebook that keeps them

Practice
Build pattern recognition, not solution memorisation
We watched candidates memorise 300 LeetCode solutions and still struggle in interviews. The gap is pattern recognition. Every problem on AlgoInsight is tagged to a pattern, not just a topic - so you build transferable instincts.
- 640+ problems organised by pattern (Sliding Window, BFS/DFS, DP, and more)
- System Design simulator with real-time AI evaluation of your architecture
- Algorithm Visualizer that makes the logic click visually

Interview
Simulate real pressure before the real stakes
Reading about interviews and doing interviews are completely different experiences. Our four AI portals put you in the chair - with follow-up questions, timed pressure, silence when you think, and a detailed scorecard when it's over.
- DSA, System Design, Technical, and Behavioral AI interview portals
- AI follows up, pushes back, and hints - exactly like a real interviewer
- Scorecard breaks down correctness, approach, and communication separately

Plan
A mentor that knows your progress, and a dated plan to your interview
Preparation fails on structure, not effort. The Prep Planner turns your role, level and real weekly hours into a day-by-day schedule built from this site's own lessons and problems, and ticks itself off as you work. The AI Mentor sits beside it - it can see your progress and your mock scores, so its advice is about you.
- A dated, day-by-day plan that re-flows every morning around what you actually did
- An AI mentor that answers any hour and knows your courses, scores and weak patterns
- Resume builder, AI resume review and a jobs board for the last mile

What we built
Seven deeply integrated tools covering every stage of the tech interview journey.
AI Mentor
A coach inside the site that knows your account - the courses you are part-way through, your mock interview scores, your weak patterns - and answers any hour with the next concrete step.
Prep Planner
Your role, your level and the hours you really have become a dated, day-by-day plan built from our own lessons and problems - and it ticks itself off as you work.
System Design Practice
100+ HLD and LLD interview questions across 20+ categories. AI evaluates your architecture, trade-off analysis, and scalability thinking in real time.
DSA Problem Library
640+ curated problems organised by pattern - not just topic. Filter by difficulty, company, and tier. Practice in an AI-powered IDE with instant feedback.
Algorithm Visualizer
Step through sorting, tree traversals, graph algorithms, and dynamic programming with animated, interactive breakdowns that make patterns click.
Structured Courses
AI summaries, adaptive quizzes, text-to-speech, and personal notes on every topic. Buy individual courses for lifetime access - no subscription required.

Our values
The principles behind every product decision we make.
Outcome-First
Every feature we ship is judged by one question: does this help a candidate get the offer? No vanity metrics. No feature bloat.
AI with Structure
AI alone is just a faster search engine. We pair AI with a proven preparation structure - Learn, Practice, Interview - so it actually changes outcomes.
Pattern Over Memorisation
We teach the 20 patterns that unlock 500 problems. Recognise the pattern, and every new problem feels like one you've seen before.
Accessible to All
World-class prep shouldn't be gated behind a $300/month subscription. Core content is free. Premium goes deeper. No one gets left behind.
Built with Empathy
We've been on your side of the table. We know what 3am prep anxiety feels like. Every product decision comes from that lived experience.
Honest by Default
No invented testimonials, no fake credentials, no dark patterns. If a claim on this site can't be verified by using the product, we don't make it.
How we got here
An honest look at the journey - from a conversation to a platform used by engineers worldwide.
Why do smart, hardworking candidates keep failing interviews they were technically prepared for? Watching it happen again and again made the answer obvious: it isn't intelligence or effort. It's that nobody practices the actual skill - performing under pressure. That itch became AlgoInsight.
No VC pitch decks - just building the thing that should exist. The course platform, the DSA problem library, the system design simulator, and the algorithm visualizer came together one late night at a time.
Then AI went into the full preparation loop - adaptive quizzes, system design evaluation, behavioral coaching, instant DSA feedback, and finally the thing nothing else offered: an AI that interviews you back. Not AI as a gimmick. AI as the interviewer you can practice against.
AlgoInsight is live with 4 AI interview portals, 500+ problems, and 20+ courses - with a free demo so you can judge it yourself. Improvements ship every week, and early users' feedback directly shapes what gets built next.
Who's behind it
An independent, engineer-built product - no growth team, no fake faces, no invented credentials. Just the product, built in public, improving every week.
AlgoInsight is built in public by an engineer who got tired of prep sites that never interview you back. Solving problems alone doesn't prepare you for a person probing your reasoning under a timer - so we built the AI interviewer we wished existed.
Every feature you see - the four interview portals, the visualizers, the scoring rubrics - exists because someone hit a wall preparing for interviews and we built the tool that removes it. That loop continues with every user: your feedback lands directly with the person who writes the code.
We've been in your seat. We know what's at stake. That's why we're here.
