LinkedIn Post Generator
Chrome extension to automate LinkedIn post creation with AI — from news research to formatted publishing
Discuss a similar projectRéponse courte
LinkedIn Post Generator is a Chrome extension built by Digit-AI to automate LinkedIn post creation. It combines news research via NewsAPI, content generation with Claude Sonnet 4 or GPT-4o, Unicode Mathematical Bold formatting (persistent on LinkedIn) and image generation via DALL-E 3 or Unsplash. The result: the time to create a post drops from 30–60 minutes to 3–5 minutes (−90%), with consistent quality thanks to the built-in Skill v4 framework.
Context & Stakes
A time-consuming, fragmented creation process with no quality framework
Professionals who post regularly on LinkedIn — community managers, executives, consultants, marketing teams — spend 30 to 60 minutes per post: researching relevant news across several sites, writing engaging copy, fighting formatting loss (LinkedIn strips Markdown bold on paste) and finding a suitable image. Without a writing framework, quality and tone vary significantly from one post to the next.
Time-consuming creation
Between researching a news item, writing, formatting and finding an image, each post requires 30 to 60 minutes of manual work.
Fragmented monitoring
Relevant information is scattered across many sources. No tool centralizes recent news research by topic.
Formatting loss
LinkedIn systematically strips Markdown bold on copy-paste, reducing the readability and visual impact of posts.
Inconsistent quality
Without a structured editorial framework, the tone, structure and engagement of posts vary widely from one publication to the next.
Functional scope
Community managers, personal branders, executives, consultants, marketing teams. Processes covered: news research, AI content generation, Unicode Bold formatting, image generation, assisted publishing, post history.
Key constraints
Chrome extension only (Manifest V3) · Local-only storage via chrome.storage · API keys provided by the user · Multi-provider AI (Claude / OpenAI) · LinkedIn Desktop compatibility · ZIP distribution.
Objectives & Scope
Three levels of objectives, each tied to a measured KPI
Strategic objective
Cut LinkedIn content creation time by 90% so professionals can post regularly without sacrificing their productivity.
Operational objective
Automate the full creation pipeline: news research (NewsAPI) → selection → AI generation → Unicode Bold formatting → image generation → assisted publishing, in a single interface.
Technical objective
Deliver a Chrome Manifest V3 extension with a dual interface (side panel + popup), 100% local storage and a multi-provider architecture with no server backend.

Distribution
Differentiating pattern — Skill v4 framework: unlike generic AI writing tools, LinkedIn Post Generator embeds a specialized Skill v4 framework that structures every post for the 2025 LinkedIn algorithm: a 2-line emotional hook, paragraphs of 4–5 lines maximum, 3–5 strategic emojis, and automatic conversion to Unicode Mathematical Bold (𝗕𝗼𝗹𝗱) — formatting that survives copy-paste, where standard Markdown is systematically stripped by LinkedIn.
Results, Gains & ROI
Measured gains across the entire LinkedIn content creation cycle
| Indicator | Before | After | Gain |
|---|---|---|---|
| Time to create a post | 30–60 minutes (manual) | 3–5 minutes | −90% reduction |
| News research | Manual, across multiple sites | Automated via NewsAPI (7 days) | ÷10 |
| LinkedIn formatting | Copy-paste, bold lost | Persistent Unicode Mathematical Bold | Zero loss |
| Image generation | Manual search, edits | DALL-E 3 / Unsplash in 1 click | ×10 faster |
| Quality & consistency | Varies by author | Skill v4 framework, consistent tone | Consistent quality |
Qualitative gains
Productivity
The full creation cycle — research, writing, formatting, image — goes from 30–60 minutes to under 5 minutes thanks to end-to-end automation.
Consistent quality
The Skill v4 framework guarantees a professional structure (2-line emotional hook, paragraphs ≤5 lines, strategic emojis) aligned with the 2025 LinkedIn algorithm.
Persistent formatting
Automatic conversion to Unicode Mathematical Bold (𝗕𝗼𝗹𝗱): bold survives copy-paste on LinkedIn, where Markdown is systematically stripped.
Privacy
100% local storage via chrome.storage. API keys are provided by the user and never pass through a third-party server.
Multi-AI
Instant choice between Claude Sonnet 4, GPT-4o, Grok or Perplexity depending on the need: creativity, factual accuracy, tone, or real-time research.
Accessibility
Dual interface — extended side panel (750–900 px) for the full experience and a compact popup (500 px) for quick access — integrates natively into Chrome.
