Picking an AI avatar video tool is a three-axis decision: how many ready avatars and languages the cluster exposes at your tier, how the bill scales (credits per minute, a minute cap, or per seat), and whether the tool is built for a solo creator (HeyGen free tier), a marketing team (Elai 4K + 50 min), or an L&D/LMS workflow (Colossyan SCORM export). The five we track — Synthesia, HeyGen, D-ID, Elai AI and Colossyan — span all three shapes. Synthesia is the category reference point on avatar breadth (230+ ready avatars, 140+ languages), but its Basic $0 tier caps at one video per month and nothing free is watermark-free; paid tiers run Starter $29/mo / Creator $89/mo with annual discounts bringing Creator to $64–89. HeyGen gives the most usable free tier (three 720p watermarked videos per month, no card) and the strongest API orientation at Pro ($49/mo, 1,000 credits including 4K and commercial license; annual Creator $24/mo vs Pro $79/mo widens the gap). D-ID is the cheapest paid entry at $4.70/mo annual (Lite, 40 credits ≈ 10 min of 1080p, still watermarked; Pro $16/mo annual adds the commercial license and 100 credits), and it has no free tier — the 14-day trial ships watermarked at 3 min full-screen. Elai AI targets marketing and L&D teams on a minute-based model: Creator $29/mo = 15 min/month at 1080p, Team $125/mo = 50 min at 4K with 3 editors and SCORM export; no published annual discount, Enterprise is quote-only. Colossyan is the LMS-flavored avatar tool — 300+ NEO avatars, 20 min/month of free generation (watermarked), Professional $59/mo (annual $39) adds 10 min of NEO2, SCORM exports and watermark removal; add-on seats $30/user/mo, Enterprise custom. The cluster's free tiers differ sharply in shape — Synthesia 1 video/mo cap, HeyGen 3 watermarked clips, Colossyan 20 min of NEO — so start from how much output you actually need, not from the avatar count.
