How it works

From a keyword sheet to a site worth building

Four steps, most of them free and instant. The AI only sees niches that already look winnable, so a free key goes a long way.

How it works

From a keyword search to sites worth building

Import once. The free, instant steps cut the list down before any AI is used, so your AI only judges niches that already look winnable.

Funnel: 18,902 keywords grouped into 1,284 niches, filtered to 212 micro-site fits, 37 worth building
  1. 01

    Find your keywords

    Search our own keyword database by country in Keyword Explorer, and send the best ones to Keyword Checker. An Ahrefs or Semrush export, or your own list, works too.

  2. 02

    Filter for free

    Micro-site rules, intent, volume and keyword count. Instant, and no AI is used.

  3. 03

    Get the AI verdict

    Your AI judges 10 niches per request and explains why. Verdicts are saved, so nothing is paid for twice.

  4. 04

    Grab the domain and build

    Free exact-match domains are checked live on every card, so you can register the one you want.

Before you start

What you need

Nothing expensive. Most people start with a free AI key and a keyword list they already have.

A Windows PC or a Mac

Niche Miner is a desktop app for Windows and Mac. Your sheets and sessions stay on your computer.

Keywords

Not even that: search our own keyword database in Keyword Explorer. Ahrefs or Semrush exports, or your own list, also work.

A free AI key

A Google Gemini key is free and enough to start. Claude, OpenAI, Groq, DeepSeek and others work too. Or take Pro AI ($20) and we supply the AI, so there is no key to get at all.

Your first week

From download to your first site

  1. Day 1 · 10 minutes

    Install and connect a free AI

    Download Niche Miner, sign up free (no invite code), and paste a free Google Gemini key in Settings.

  2. Day 1

    Import your first sheet

    Search Keyword Explorer for your country (or open Trending), send the best keywords to Keyword Checker, and filter to micro-site niches. Ahrefs and Semrush exports work too.

  3. Night 1

    Let the AI work overnight

    Use Run later to judge everything while you sleep. Free AI limits reset, and verdicts are saved.

    Open the AI ✓ cards, read the reasons, peek at Google, and check the free domains.

  5. Days 3–7

    Build your site

    Register the free domain of your favourite and build. PubHound shows which sites already earn in that niche.

Most micro-niche sites fail before the first article is written

Not because of the content. Because of the niche. Niche Miner checks what sinks a small site before you spend a rupee on a domain.

  • Big brands own the results

    If page one is newspapers and giant sites, a new micro site never gets seen. The rules and the AI drop those niches first.

  • There is no real demand

    One lucky keyword is not a niche. Keywords are grouped, so you see the total monthly searches behind each idea.

  • The right domain is gone

    Exact-match domains are checked live on popular endings and your country's own, right on the card.

Your next site is already in your keyword list

Import it, filter it, and let Niche Miner show you the niches worth a domain.
