The Problem

Professionals spend hours daily on LinkedIn tasks that are repetitive but require personalization: writing thoughtful comments for visibility, tailoring resumes for each job application, and crafting professional messages to recruiters. The current workflow involves copy-pasting between LinkedIn and ChatGPT, manually comparing job descriptions to resumes, and struggling to maintain consistent engagement while job searching or building a personal brand.

Potential Solution

A comprehensive Chrome extension suite that works natively inside LinkedIn to automate personalization at scale. Features include one-click comment generation on posts, automatic job description scanning that highlights resume gaps and suggests tailored rewrites, and instant message rewriting with multiple tone options (professional/friendly/persuasive). All AI processing happens contextually within the LinkedIn interface, eliminating copy-paste workflows.

Why Now?

Chrome's built-in AI capabilities and local LLM processing are making privacy-first browser extensions viable without expensive API costs. Simultaneously, LinkedIn has become the dominant platform for professional networking and job searching, with algorithm changes rewarding consistent engagement—creating intense pressure on users to produce more personalized content faster.

A Resource to Help Startups Improve Hiring and Candidate Applications

r/startup_resourcesJul 27, 2026

For early-stage startups, hiring is often one of the biggest challenges, and reviewing resumes can take a lot of time. A resume builder that helps applicants create clearer, ATS-friendly resumes and tailor them to specific job descriptions can improve the quality of applications startups receive while also helping job seekers present their experience more effectively. I am the founder of **ProResume**, an AI-powered resume builder that helps users create professional resumes, improve their content with AI, tailor resumes to job descriptions, and check ATS compatibility. I'm sharing it here to get feedback from the startup community. I'd love to know what features you think would make a resume builder more valuable for founders, hiring managers, and job seekers. My post comply with the rules.

Built an AI tool to write LinkedIn posts that actually sound like you

r/SideProjectJul 20, 2026

Hi everyone! Over the last few months, I've been working on a side project to solve a problem I kept running into. Whenever I used AI to write LinkedIn posts, the output felt generic. It was easy to tell it was AI-generated, and it never matched my writing style. So I built my own solution. Instead of using a single prompt, it goes through multiple steps—idea generation, writing, reviewing, and editing—to create posts that feel more natural and personal. It's still an early version, and I'm actively improving it based on feedback. You can try it here: [**linkdin-agent-ai.vercel.app/.../**](linkdin-agent-ai.vercel.app)
