Overview
Your personal AI assistant, on any site.. I wanted to create an AI assistant that worked the way I do—seamlessly integrated into my workflow, on any site, without the constant copy-pasting to a separate chat window.
Operator: Gourav Goyal. Website: https://jetwriter.ai/
Estimated split: about 90% of the work automated, 10% human.
Realistic income
Indie Hackers (checked Oct 29, 2026) shows $10,226 per month in revenue verified through Stripe on the founder’s product page. This is one operator’s result, often after months or years of work, and doesn’t predict yours. Check the live source — numbers change.
Risks
- Host sites can change their pages and break the extension.
- Store policy changes and copycats.
- Startup cost and time to first dollar are not disclosed.
*Income figures are illustrative ranges based on public pricing and typical outcomes reported by practitioners, not guarantees. Most new online businesses earn little or nothing at first. Not financial, legal or tax advice.
