Applyre AI

paid

Applyre AI automates the most time-consuming parts of job hunting. Instead of searching and applying manually, the platform scans thousands of company career pages every day, finds roles posted within the last 24 hours, and filters them by your exact preferences—like location, remote, salary, and skills. It even skips companies you’ve blocked, so only relevant opportunities reach you. Once jobs are identified, Applyre’s AI fills out the application form with your profile, customises your resume to the job description, and generates a tailored cover letter that reads like you wrote it yourself. Every application is then reviewed by a real person who checks accuracy, tone, formatting, and overall fit before submission. The application is submitted directly through the company’s career page—just as you would do manually—and you receive the confirmation email in your own inbox. With plans starting at 40 applications per month, Applyre helps you reclaim over 25 hours each week and get significantly more interviews by getting your application in front of hiring managers early, beating both applicant tracking systems and the competition.

Editaimg: An AI Image Editor Built by a Dev Who Struggles with UI The Backstory As a full-stack developer, I’ve always been "vision-challenged." I’m not great at UI design, and while I have some Photoshop skills, I use them so infrequently that I have to re-learn the tools every time I open the app. I wanted a way to edit images that didn't feel like a struggle. The Problem with 2023 AI In 2023, I tried building an AI editor, but it didn't work. Image-to-image models would often generate an entirely different picture when you just wanted to fix one small detail. It was expensive and unusable for real work. ### The 2025 Solution: Editaimg Technology has finally caught up. I built Editaimg to make professional editing as simple as a chat: Natural Language Editing : Describe what you want to fix in plain English. Precision Control : Replace or remove objects without ruining the rest of the image. Essential Utilities : High-res upscaling, smart background removal, and watermark cleaning. Scenario-Focused : Optimized for Amazon product shots and quick marketing assets. Stop struggling with complex tools. Just tell the AI what to do.
