After 5 years of building SelectorsHub, I learnt 3 things I wish someone had told me earlier.
1. Ship ugly, ship early
2. Talk to your users every day
3. Don’t wait for funding
We crossed 2 million testers last week, and I still don’t have a single investor.

FormatHub: Post or comment
FormatHub
AI prompt
Task
Write a 1,200-word blog post about test automation for a QA audience.
Context
Readers are manual testers who have not automated before. Assume no framework is in place yet.
Output
Intro, four sections with subheadings, short conclusion. Practical tone, concrete examples, no hype.
One right-click, wherever you are typing
FormatHub knows what you are writing and formats it that way. An email gets paragraphs, lists and a sign-off. A LinkedIn post gets short lines, bold where it counts and your hashtags tidied to the end. A comment gets tightened to a few clear sentences.
And an AI prompt gets turned into a proper brief: the task, the context the model needs and the output you want. Most weak answers come from a vague ask, not a weak model.
- Gmail
- Outlook
- Yahoo
- Zoho
- Proton
- X
- Claude
- ChatGPT
- Gemini
- Perplexity
Anywhere else, the same right-click still cleans up plain text.
Format, Rewrite or Shorten
Format fixes grammar and spacing and keeps your own words. Rewrite improves the writing: a sharper opening, no filler, no choppy sentences. Shorten says the same thing in fewer words.
That is the whole menu. The voice for Rewrite is a setting, not another submenu - pick professional, friendly or humble once and it stays. Tone rarely changes between messages; the job does.
- Format
- Rewrite
- Shorten
- Voice: as you wrote it
- Professional
- Friendly
- Humble
Select only part of what you wrote to format just that part. In email, your signature and the quoted reply below it are always left untouched.
