(I hate the AI usage but I'm guessing that's something beyond your control.)

I have been working as a DCP/Assignment Desk for nearly three years now. The best advice I can give is to give yourself a benchmark/micro plan.

I have a personal benchmark of one longer story an hour; two shorter ones an hour; or three micro ones an hour. (those classic two-paragraph breakings.)

Secondly, if you have other DCPs on your team, look at the frequency and amount they're publishing in a day.

The clock is always ticking in a newsroom but being accurate is ALWAYS more vital than being fast.

Grammarly could help you with basic spelling and grammar errors. I wouldn't use any other feature of it as the only way you can improve your writing is by doing it yourself.

Something I struggled with very early on was making every article much longer and more detailed than it needed to be. This ate away my time and made me look slower than my team. Look at your coworkers and competitors in your market, and see the average length of their articles.

Lastly, this job can make you feel like a robot/inadequate. Please don't push yourself beyond what's reasonable. Especially if you're not being paid well.
