LinkedGrow
A tool that learns how you write from a handful of your old LinkedIn posts, then helps you turn a one-line idea, a URL, or a Reddit thread into a new post in your own voice — and you plug in your own AI key instead of paying a flat subscription for the AI

Description
Growing a presence on LinkedIn usually requires posting consistently in a voice that doesn't sound like generic AI marketing copy, which is exactly what most AI writing tools produce. LinkedGrow tries to solve the 'sounds like a robot' problem by reading up to 5 of your existing posts and building a voice model from them before generating anything new.
LinkedGrow is a LinkedIn content platform covering writing, scheduling, and analytics, built around a bring-your-own-API-key (BYOK) model: instead of LinkedGrow marking up the cost of the underlying AI model, you connect your own key from one of 26+ supported models across OpenAI, Anthropic, Google, and others, and pay LinkedGrow separately for the app itself (Starter $13/month, Pro $27/month, Business $55/month) plus your own token costs (roughly $2-4/month on average). Features include turning a one-liner, URL, or Reddit thread into a draft post, a carousel generator, a claimed 91%-accuracy virality scorer, content repurposing from blogs and videos, 40+ language support, an analytics dashboard, A/B testing, and team features like role-based access and approval workflows. It offers a 7-day Pro trial with no credit card required, and names Taplio, AuthoredUp, Supergrow, Kleo, MagicPost, and ContentIn as direct competitors.
💬 Our review
The short version: LinkedGrow's bring-your-own-key pricing is the most interesting thing about it — most LinkedIn tools charge $50-100+/month with AI costs baked in and marked up, while LinkedGrow charges less for the app and lets you pay near-wholesale for the AI itself, which adds up to real savings if you're a heavy user.
Against Taplio or AuthoredUp, the established players in this space, LinkedGrow's BYOK model is cheaper for anyone posting frequently, but it does add a small setup step (getting and connecting an API key) that a non-technical user might find more friction than a flat all-inclusive subscription. The claimed accuracy numbers (99% voice-matching, 91% virality scoring) are marketing claims from the company itself, not independently verified, so treat them as directional rather than exact — the real test is whether a handful of generated posts actually sound like you, which is worth checking in the 7-day free trial before paying. It's a strong pick for a founder or creator who posts often enough that per-token AI costs matter and who's comfortable connecting an API key; it's less appealing for someone who wants the absolute simplest signup-and-go experience with no technical setup at all.
