Two jobs stop feeling like babysitting. Long documents: hand it a sixty-page PDF and ask about one paragraph, and it answers that paragraph instead of wandering off. Code edits: give it a file and it follows your structure, leaving the parts you never mentioned alone. Writing holds my outline better than most tools I have tried. The cost is quota, because heavy sessions burn through limits, so I plan the expensive requests and keep the small ones for later.
Yes — there is a free tier you can start on. Whether it's enough depends on how much you use it; limits are on the official pricing page.
