ChatGPT: where it shines, where it lags
ChatGPT is OpenAI’s conversational AI assistant. It launched in November 2022 and reached 100 million users in two months, the fastest growth of any consumer app at that time. Today it handles text generation, code writing, image creation, file analysis, and web browsing in a single interface.
The free tier gives you access to GPT-4o with daily limits. ChatGPT Plus costs $20 per month and removes most of those caps. ChatGPT Pro runs $200 per month and adds OpenAI’s o1 Pro model, which is slower but more accurate on complex reasoning tasks.
What ChatGPT does well is broad. It writes emails, drafts reports, debugs code, answers research questions, and summarizes documents. The memory feature lets it store facts about you across conversations, which saves time for repeat users. The custom GPT store has over 3 million published GPTs built by outside developers, covering legal templates, spreadsheet helpers, and dozens of other categories.
The API has thorough documentation and a large developer community. Developers can connect ChatGPT to almost any product. Zapier alone lists over 1,000 ChatGPT automations.
Where ChatGPT falls short is consistency. It still hallucinates. It can state a wrong fact with full confidence, which means you can’t skip verifying claims. The free tier is slower and more restricted than it was in 2023, and OpenAI has raised prices twice since then.
ChatGPT also doesn’t produce video. It can write a script or suggest shot ideas, but it won’t render anything. For creators who need video output, ChatGPT covers only part of the workflow.
The mobile app works well on iOS and Android. Voice mode, added in late 2024, supports real-time spoken conversation, which is useful for brainstorming on the go.
One underrated feature is Advanced Data Analysis. Upload a spreadsheet and ask ChatGPT to chart trends, run regressions, or clean the data. It handles most standard tasks without needing Excel or Python skills.
For teams, ChatGPT Team costs $30 per user per month, billed annually, and keeps company data out of OpenAI’s training sets. Enterprise pricing is custom and includes single sign-on, admin controls, and longer context windows.
The platform works best for knowledge workers: writers, marketers, developers, analysts, and consultants. If your job centers on text, data, or code, the Plus subscription earns back its cost within the first week of regular use.
HeyGen: where it shines, where it lags
HeyGen is a video generation platform. It lets you create videos using AI avatars, no camera required. You upload a script, pick an avatar or build one from your own face, and HeyGen renders a finished video in minutes.
The company launched in 2022. By 2024 it had over 40,000 paying customers and was processing more than 1 million videos per month.
The free tier gives you one video per month, capped at one minute, with a watermark on the output. The Creator plan at $29 per month removes the watermark and provides 15 video credits per month. The Team plan at $89 per month adds collaboration features and more credits.
Where HeyGen stands out is speed. A 90-second explainer video that would take a production crew several hours to film can be ready in under 10 minutes. The avatar lip sync is tight enough that most viewers won’t notice it’s generated. Over 100 stock avatars cover a range of ages, genders, and backgrounds.
The custom avatar feature is one of HeyGen’s strongest draws. Record five minutes of yourself speaking on camera, submit the footage, and HeyGen builds a digital version of you. Then you can generate new videos without ever recording again. Businesses use this for onboarding videos, product tutorials, and social content at scale.
Video translation is another strong feature. HeyGen can translate a video into 40-plus languages and re-sync the avatar’s lips to match the new audio. A single English video becomes Spanish, French, German, and Mandarin versions with the same face. The accuracy on major languages is solid. Less common languages get shakier results.
Where HeyGen falls short is scope. It’s a video tool, nothing more. It won’t write your script, answer your research questions, or analyze data. You bring the content; it renders the output.
The avatars can look slightly off in certain lighting conditions or with fast head movements. Longer videos, over five minutes, sometimes show sync drift near the end. Customer support response times have drawn complaints from Team plan users.
HeyGen integrates with Zapier, HubSpot, and Salesforce and offers a public API. The API supports programmatic video creation, which suits automated personalized video campaigns.
The platform fits marketers, sales teams, learning and development professionals, and content creators who need video at volume without a production crew.
The verdict
Pick ChatGPT if your work centers on text, code, or data. It’s the right tool for writers who need a drafting assistant, developers who want inline code help, and analysts who process documents or spreadsheets daily. At $20 per month, the Plus plan pays for itself quickly if you use it every day.
Pick HeyGen if you need video at volume. Sales teams sending personalized video outreach, HR departments building onboarding content, and marketers producing localized video campaigns will get direct, measurable value from HeyGen. The Creator plan at $29 per month costs less per finished video than paying a freelance editor for a single project.
Some teams need both. A content team can use ChatGPT to write scripts and HeyGen to render them into finished videos. That combined workflow costs $49 per month and replaces hours of production work each week.
If you can only pick one, match the tool to your primary output. Text workers choose ChatGPT. Video workers choose HeyGen. The tools don’t overlap enough for one to substitute the other.
FAQ
Can ChatGPT make videos?
ChatGPT can write a video script, outline a storyboard, or suggest talking points, but it won’t render footage or produce a finished video file. For video output, you need a separate tool like HeyGen, Sora, or Runway. Many creators use ChatGPT to write the script and HeyGen to render it, a common workflow for solo creators and small marketing teams that want to cut production time.
Is HeyGen free to try?
Yes. HeyGen’s free tier includes one video per month, capped at one minute, with a watermark on the output. That’s enough to test the platform but not enough for regular use. The Creator plan at $29 per month removes the watermark and provides 15 video credits per month, with each credit producing one video up to five minutes long.
Which tool has a better API for developers?
ChatGPT’s API is more mature and widely used. OpenAI’s documentation covers text, images, audio, and embeddings, and the developer community has thousands of open source examples and libraries. HeyGen’s API is solid for video generation and supports programmatic video creation, but the community and documentation are smaller. If your product needs both text and video, you’d likely connect to both APIs.
