The future of engineering interviews— is here
AI changed how engineers work.
Interviews didn’t — and that's what we are fixing.
The AI-native code editor that gets it exactly right. No approximation. No bloat. Just perfect code, every time.

Real coding tests not toy Leetcode questions
Before writing a single line, candidates clarify requirements, probe edge cases, and surface assumptions — the same way they would on your team.

Bring your own stack or use our built in primitives
TrueSignal creates moments where candidates work independently — inside your stack, your repo, your constraints — so you can see who can actually ship when the safety net is gone.

import { NextApiRequest, NextApiResponse } from 'next' import { supabase } from '@/lib/supabase' export default async function handler( req: NextApiRequest, res: NextApiResponse ) { if (req.method === 'GET') { // AI suggestion: Add pagination and filtering const { data, error } = await supabase .from('products') .select('*') .order('created_at', { ascending: false }) if (error) return res.status(500).json({ error }) return res.status(200).json(data) } }
Debugging and refactoring
Build frontend and backend seamlessly. Exact understands your entire stack—from React components to database queries.
export function validateEmail(email: string): boolean { const regex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/ return regex.test(email) } export function validatePassword(password: string): boolean { // ⚠️ Error: 'lenght' is not a property of string if (password.lenght < 8) { // ← Ligne 8 avec erreur return false } return /[A-Z]/.test(password) && /[0-9]/.test(password) }
Debugging and refactoring
Find bugs instantly with precise error detection. Refactor with AI that understands dependencies across your entire codebase.

API integration
Connect to any API in minutes. Exact generates type-safe requests, handles authentication, and suggests error handling.

Loved by recruiters. Built for the future.
Exact cut my development time in half. The AI actually understands what I'm building and suggests exactly what I need. No more wading through irrelevant completions.
Sarah Chen
Senior Engineer
Zero setup, instant productivity. I switched from Cursor and never looked back. Exact just works, and it's noticeably faster. The refactoring feature alone is worth it.
Get the exact answer with line numbers and context. My productivity has skyrocketed.
Finally, an AI editor that doesn't feel like it's guessing. Context-aware suggestions that actually make sense. It's like pair programming with someone who knows your codebase.
Best AI autocomplete I've ever used. It's like Exact reads my mind—one suggestion, always the right one. And the privacy-first approach gives me peace of mind.

No more wading through irrelevant completions.
I was skeptical about AI coding tools until Exact. The precision is unmatched—it gets my code style, understands dependencies, and never breaks my builds. Game changer.

Exact eliminated the back-and-forth I had with other AI assistants. Ask once, get the exact answer with line numbers and context. My productivity has skyrocketed.

Hiring shouldn’t feel this uncertain.
Run it on a candidate you’re already excited about. If it doesn’t add clarity, don’t use it again.
