LinkedGrow

LinkedGrow is a bring-your-own-key (BYOK) AI tool for generating, scheduling, and tracking LinkedIn posts using your own OpenAI, Claude, or Gemini API key instead of paying a bundled AI markup.

What is LinkedGrow?

LinkedGrow is a LinkedIn-focused AI content platform built around a bring-your-own-key (BYOK) model: instead of bundling AI usage into a $30-80/month subscription like Taplio or AuthoredUp, you connect your own OpenAI, Anthropic, Google, Grok, Perplexity, or Kimi API key and pay the provider directly — typically a few dollars a month. The tool then covers the full publishing loop: an ideas generator, a hooks generator, voice training that models your style from up to five sample posts, carousel and image generation, a visual content calendar with scheduling (including first-comment scheduling), A/B testing with virality scoring, content repurposing from URLs and Reddit threads, and an analytics layer with engagement, impressions, best-posting-time insights, and exportable reports. Team features add role-based collaboration and a REST API for agencies. A free plan plus 13 no-signup free tools serve as a funnel, while paid tiers run from Starter ($13/mo) to Business ($55/mo). The current promotion sells the full Business plan for a $99 one-time lifetime payment, though the product is only ~4 months old and carries the usual independent-vendor longevity risk.

Key Features

• Unlimited AI Post Generation — Write a week of posts in your voice in minutes using your own API key from OpenAI, Claude, Gemini, Grok, Perplexity, or Kimi, with no caps or throttling.

• Content Calendar + Smart Scheduling — Plan weeks of content and auto-publish at audience-aware best posting times, including first-comment scheduling.
• A/B Testing + Virality Scoring — Test post variants side-by-side and score drafts for predicted engagement before publishing.
• Content Repurposing — Turn YouTube videos, blog posts, Reddit threads, or any URL into LinkedIn drafts written in your voice.
• Team Collaboration + API — Role-based access, shared workflows, and a REST API for agencies and growing teams.

Who is it for?

• Solo founders and creators building a personal brand on LinkedIn who want consistent posting without spending hours writing
• Freelance writers and ghostwriters who need drafts in a client's voice using the client's own API key
• Agencies managing multiple client accounts who want role-based access and scheduling in one place
• Cost-conscious users tired of paying $49+/month to LinkedIn content tools for AI they can buy direct for a few dollars
• Multi-language creators — the generator writes in 40+ languages

Who is it NOT for?

• Anyone who needs an all-in-one social suite: this is LinkedIn only, with no X, Facebook, or Instagram cross-posting
• Non-technical users who won't set up and manage an OpenAI, Claude, or Gemini API key
• Users who prefer predictable flat pricing — BYOK means your bill varies with how much you generate
• Buyers who need a proven, long-track-record vendor with deep third-party reviews before trusting a lifetime purchase
• Teams that rely on native CRM integrations, inbox management, or comment automation at scale
