Hintsay: AI writing assistant for LinkedIn

Months of LinkedIn content in minutes, in your own voice

In short

Hintsay is an AI writing assistant that helps professionals build their personal brand on LinkedIn — turning a keyword or an idea into finished, on-brand posts in minutes instead of hours. I designed and built it end to end, from the AI that writes in your voice to the interface that keeps you in control. The promise, in one line: generate months of LinkedIn content in minutes.

Problem

Most professionals know that showing up on LinkedIn grows their brand and their business. Actually doing it, consistently, is the hard part:

  • No time to write regularly next to a full workload
  • Writer's block — staring at a blank post with no angle
  • Guesswork about what actually resonates with their audience
  • Voice drift — hard to sound like themselves at speed
  • Inconsistency — irregular posting quietly kills reach

Approach

A writing assistant that makes content creation faster and better — without taking the person out of the loop.

What it does:

  • Generates posts from proven, high-performing templates
  • Turns a keyword into ready-to-use topic suggestions
  • Personalises to your LinkedIn profile so it sounds like you
  • Works in English and Dutch
  • Keeps your personal voice and style intact

Design process:

Phase What happened

Key takeaways

  1. AI as assistant, not replacement — people want to stay in control of what goes out under their name.
  2. Speed is the product — professionals have little time; every second of friction costs a post.
  3. Personalisation is non-negotiable — generic content doesn't land; context is everything.
  4. Keep up or fall behind — LinkedIn's algorithm keeps shifting, so the tool has to keep learning.
