HeyGen is one of the best-known AI avatar tools. You type a script, pick an avatar or a custom one of yourself, and get a talking-head video without setting up a camera.
For a one-person business, the real question comes first: do you need an avatar at all? Many solo creators get further by filming a quick phone video and letting AI handle the captions and clips.
This guide covers both paths: when to stay on HeyGen, when Synthesia or Captions fits better, and when to skip avatars for Submagic or OpusClip. For the wider list of tools that turn one video into many posts, my AI content repurposing tools roundup covers that.
HeyGen Alternatives: The Short Answer
Stay on HeyGen if you want a custom avatar of yourself for marketing and social videos. Choose Synthesia if your videos are mostly training, onboarding, or course lessons. Choose Captions if you want to film, edit, and make avatar videos from your phone. Skip avatars and use Submagic or OpusClip if you are willing to film yourself.
Do You Need an AI Avatar at All?
An avatar solves one problem: a talking-head video without filming. That is worth paying for if you dislike being on camera, need several languages, or plan more videos than you could record.
If none of that is true, an avatar can be the expensive way to do a cheap job. And if you already record long videos, podcasts, or webinars, you may have plenty of clips sitting in your files. Pick a branch:
Avatar path: HeyGen, Synthesia, or Captions.
Film yourself path: Submagic for captions and editing, or OpusClip for cutting long videos into clips.
What Each Tool Is Built For
HeyGen. HeyGen turns scripts into videos with AI avatars and AI voices. Its plans include ready-made presenters, a Custom Video Avatar of your own likeness, and on paid plans, 175+ languages and dialects.
Synthesia. Synthesia also makes avatar videos from a script. Its pricing page leans toward training, listing roleplays, surveys, interactive avatars, and learner seats next to its video editor.
Captions. Captions is a phone-first AI video app. It covers both branches: avatar features like AI Twin, plus tools for footage you film yourself, such as a teleprompter, AI Edit, and clips from long videos.
Submagic. Submagic adds AI captions and short-form polish to videos you have already filmed, priced per member with a monthly video count.
OpusClip. OpusClip uses AI to cut long videos into short clips, adds animated captions, and gives each clip a virality score.

The Costs Beyond the Sticker Price
Credits, not videos. HeyGen, Synthesia, Captions, and OpusClip all meter usage in credits. Synthesia's page estimates video at 100 credits per minute and notes that actual use varies. Check how many credits one typical video uses.
Rollover limits. HeyGen says Creator credits roll over one month. OpusClip Pro rolls unused credits over for 2 months, and Captions lets you save up to two extra months of unused credits.
Avatar add-ons. HeyGen sells extra Custom Video Avatars as an add-on on Creator and Pro. Synthesia's Studio avatar is a $1,000 a year add-on for annual plans only.
Seats and members. HeyGen Business charges $20 a seat per month for extra team members, and Submagic prices every plan per member. If an assistant needs a login, price that in.
Free plan limits. HeyGen, Synthesia, and OpusClip free plans add watermarks, and OpusClip's free clips can no longer be exported after 3 days.
HeyGen vs Synthesia: The Closest Avatar Alternative
If you want to keep using an AI avatar, Synthesia is the most direct swap. Both turn a script into a presenter video, offer avatars of yourself, and have a watermarked free plan. The differences for a solo business:
Free plan. HeyGen Free gives you 3 videos a month, up to 1 minute each. Synthesia Basic gives you 10 minutes of video a month.
Entry price. Synthesia Starter is $19 a month, and HeyGen Creator is $29 a month.
Your own avatar. HeyGen includes one Custom Video Avatar even on Free. Synthesia Pro lists 5 personal avatars.
Output. HeyGen Pro adds 4K export, and paid HeyGen plans allow videos up to 30 minutes. Synthesia Pro adds up to about 60 minutes of video a month on top of the free allowance.
Focus. HeyGen's pricing speaks to creators and marketers. Synthesia's speaks to training teams, with roleplays, surveys, and learner seats.
Choose Synthesia for lessons, onboarding, or explainers at a lower entry price. Stay on HeyGen for marketing and social videos built around your own face and voice.
When to Stay on HeyGen
You already have an avatar that looks like you. Rebuilding it in another tool costs time. My tutorial on creating a realistic AI avatar shows the HeyGen setup I recommend: a video avatar paired with a recording of your real voice.
The problem is your plan, not the tool. Unused credits mean drop a tier. Running out means compare Pro's 1,000 credits with Creator's 600.
You want a simple daily routine. My AI avatar videos guide walks through script, HeyGen avatar, Submagic edit, and posting.
When Captions Is the Better Fit
You run your content from your phone. Captions' pricing notes that the plans shown are iOS plans, and its tools include a teleprompter and AI Edit for videos you record on the spot.
You want both branches in one app. Captions offers an AI Twin of yourself and editing for footage you filmed, so you can mix avatar videos and real ones.
The Film Yourself Path: Submagic or OpusClip
Submagic for short talking-head videos. Record a short video on your phone, and Submagic adds captions and b-roll. Its pricing page also lists AI tools that remove bad takes and silences. Plans cap video length at 2 minutes on Starter and 5 on Pro, so it suits shorts. My Submagic review covers who it fits.
OpusClip for long videos you already have. If you publish YouTube videos, podcasts, or webinars, OpusClip finds clips inside them and captions them for you. My OpusClip tutorial shows how to turn long videos into clips and post them everywhere.

Common Mistakes When Choosing an AI Video Tool
Buying an avatar to avoid a short recording. If a 60-second phone video would do the job, an avatar subscription may be solving the wrong problem.
Comparing prices instead of credits. A cheaper plan with fewer credits can cost more per video.
Switching tools to fix a plan problem. Wrong credit totals are usually a tier issue.
