AI content tools produce finished material rather than answers: marketing copy in a set brand voice, edits to text a person wrote, synthetic voiceovers, images, and videos with a generated presenter. Each is built around one kind of output and goes further with it than a general chat assistant does.
Beyond output quality, two things decide the choice. The first is commercial use: whether the plan you pay for lets you publish the output, use a cloned voice or show a generated face in an ad. The second is metering. Most of these tools sell credits, characters or minutes, so the real price depends on how much you produce each month.

Methodology
We compare the tools on this page using what can be checked from the outside: published pricing and plan limits, documented features, and each vendor's own security, compliance and support documentation. This is desk research, not hands-on testing. Where something can only be judged by using a product, we say so rather than imply we measured it.

How the order is set:
Buyer's guide
ChatGPT drafts text, reads your files and, on paid plans, generates and edits images. A specialist earns its price when the job needs one of these: brand voice rules on every marketing draft (Jasper), corrections inside the apps people type in (Grammarly), voice cloning and dubbing (ElevenLabs), image and video generation with an editor (Midjourney), or avatar-presented video from a script (Synthesia). Otherwise, the assistant you already pay for may be enough.
Generated material you can't legally use is a liability. Start with commercial use: ElevenLabs' Free plan is non-commercial, and a company with more than $1 million a year in revenue must be on Midjourney Pro or Mega to own its images. Check privacy too, since Midjourney creations are public and remixable unless you're on Pro or Mega with Stealth Mode on. Then see who carries the legal risk. Synthesia's Customer Terms commit it to defend customers against third-party IP claims, while ElevenLabs' and Midjourney's terms have the customer indemnifying the vendor.
Grammarly and Jasper charge per seat, though Grammarly Pro still caps AI prompts at 2,000 per member a month. The other three sell an allowance: ElevenLabs credits (about one per character of speech), Midjourney Fast GPU hours (with unlimited Relax-mode images from Standard up) and Synthesia's 10 included minutes plus credits, about 100 per finished minute. At the limit, ElevenLabs stops until you buy a prepaid top-up, and Midjourney Basic users pay $4 per extra Fast hour. Price the plan that covers a month's output.
None of these tools removes the review step. Grammarly's Terms give no warranty that AI output is factually accurate, ElevenLabs builds a pronunciation editor into Studio, and Midjourney's docs say text in images works best in the Latin alphabet. Plan time to check facts, listen through narration and choose usable images before publishing.
FAQ
Not always. ChatGPT drafts text and, on paid plans, generates and edits images, which covers a lot of everyday content. A specialist earns its price when the job depends on something it's built around: brand voice rules applied to every draft (Jasper), corrections inside the apps people type in (Grammarly), voice cloning and dubbing (ElevenLabs), high-volume image generation with an editor (Midjourney) or presenter video from a script (Synthesia). If your need isn't one of those, try the assistant you already pay for first.
On paid plans, usually yes, but the rules differ by tool. ElevenLabs allows commercial use on paid plans; its Free plan is non-commercial. Midjourney's Terms say you own your images, but a company with more than $1 million a year in revenue must be on Pro or Mega to own them, and creations are public unless Stealth Mode is on. Synthesia bars its stock avatars from paid ads. Grammarly's and Jasper's terms treat your inputs and the AI's output as your own content.
Entry paid plans cost $6 to $69 a month on monthly billing: ElevenLabs Starter is $6, Midjourney Basic $10, Synthesia Starter $19, Grammarly Pro $30 per member and Jasper Pro $69. Yearly billing brings those to $5, $8, $14, $12 and $59 a month. The allowance matters more than the plan price: credits on ElevenLabs and Synthesia, Fast GPU hours on Midjourney and AI prompts on Grammarly. ElevenLabs has no overage billing, so work stops at zero credits until you buy a prepaid top-up.
It depends on consent and on local law. These tools are set up for cloning your own voice or one you have permission to use. ElevenLabs asks you to confirm you have the right and consent before Instant Voice Cloning, and limits Professional Voice Cloning to your own voice after verification. For custom avatars, Synthesia requires the subject to be of legal age and give free, informed consent. Rules on synthetic voices differ by country, so keep a written consent record and involve legal counsel before cloning anyone else.
