Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
ChatGPT
The assistant most creators already have open
ChatGPT is the chat assistant creators reach for between the other tools: drafting a script, cutting a description down to the character limit, arguing with a title until it stops sounding like everyone else's. The free plan answers most of that. Paying moves you onto the stronger reasoning models, lifts the message and upload limits, and adds projects, scheduled tasks and custom GPTs, which is where repeat work starts to pay for itself. There is a plan below Plus that costs eight dollars and may carry ads.
Our note
Pick the cheapest tier that stops you hitting a wall mid-session, then move up only when it happens again. The gap that matters for creative work is Free to Plus rather than Plus to Pro, because Plus is where the better reasoning models and the reusable setups start.
Grammarly
The second pair of eyes on everything you write
Grammarly catches the mistakes that get noticed in a sponsor email or a video description, and it does it inside whatever box you are typing in rather than in a separate app. The free tier covers spelling, grammar and tone. Rewriting, plagiarism detection and the larger prompt allowance sit behind Pro.
