Natively started as a pixel-perfect recreation of Cluely's interface — then kept going. If you've used Cluely, you already know how to use Natively. Same overlay, same workflow, same shortcuts. Except it's free, open-source, runs locally, supports any LLM, and has never breached a single user's data.

Looking for a free Cluely alternative? A Cluely open-source clone? You found it.

Free AI Coding Interview Assistant — Undetectable on LeetCode, HackerRank & CoderPad

Natively works as a free, undetectable AI coding interview assistant for standard online assessments. It captures your screen, analyzes the problem, and gives you real-time hints, solutions, and explanations — all through an invisible overlay that doesn't interfere with your coding environment.

Works undetected on:

• LeetCode (including LeetCode contests)
• HackerRank
• CoderPad
• Codility
• HackerEarth
• Karat
• Any browser-based coding environment

How it works:

1. Screenshot the problem with a single shortcut
2. Natively OCRs the question and sends it to your chosen AI (GPT, Claude, Gemini, or local Ollama)
3. Response appears in the invisible overlay — never on screen share

⚠️ Important: Natively is not designed to bypass dedicated proctoring software like Pearson VUE, ProctorU, or Respondus Lockdown Browser — these run at the OS level and are a different category entirely. For standard online coding assessments without dedicated proctoring software, Natively's stealth mode is not detectable.

3 things you should know before choosing an interview AI

1. Cluely had a data breach in mid-2025 that exposed 83,000 users' personal info, transcripts, and screenshots — Natively stores everything locally with limited basic telemetry and has never had a breach.
2. Final Round AI costs $149/month and its taskbar icon is visible to proctoring software — Natively is free, open-source, and has a battle-tested undetectable stealth mode.
3. LockedIn AI charges $55–70/month and locks you into their cloud LLM with no local option — Natively lets you use any model (GPT, Claude, Gemini, Llama) or go fully offline with Ollama.

⭐ Star this repo — it matters

Every star pushes Natively higher in GitHub search, helping developers and job seekers find a free, private alternative instead of paying $149/month for tools that store their data on someone else's server.
