OnTheFly
What is OnTheFly?
OnTheFly lets you multistream live video to 50-plus social platforms from one browser-based studio, record sessions automatically, and host webinars with guest invites, screen sharing, and Q&A chat. Full HD 1080p streams run over a global CDN with low-latency RTMP ingestion, real-time analytics, and optional custom RTMP destinations for your own player or website embed.
Compared with single-destination tools like native YouTube or Twitch streaming, OnTheFly is built around simultaneous distribution and post-stream repurposing. You can brand overlays, schedule streams in advance, download recordings for clips, and run pre-recorded live sessions without OBS. Plans scale from a free sampler tier through corporate plans supporting 10,000 webinar viewers.
Gamers, educators, marketers, and corporate teams use OnTheFly for product demos, podcasts, town halls, and fitness classes. The product is developed by CONTUS TECH and offers a 7-day trial on paid tiers with multistreaming included at no extra fee.
Synthesia
What is Synthesia?
Synthesia turns scripts into presenter-led videos using 240+ stock avatars, cloned voices, and lip-synced dubbing across 160+ languages. You write text, pick an avatar, and export MP4 or SCORM without cameras, studios, or voice actors. The Basic plan includes 10 minutes of generated video per month with 9 stock avatars.
Where most avatar video tools stop at export, Synthesia runs create, localize, collaborate, and publish in one workspace. Embedded videos auto-update when you edit the source, SCORM packages ship with translated versions, and Enterprise teams get Brand Kits plus SAML/SSO. Roleplay Sessions add a newer angle: practice sales or support conversations with interactive avatars that score your responses.
L&D teams use it for compliance and onboarding at scale. Sales enablement groups ship pitch refreshes in minutes instead of booking shoots. Marketing and internal comms teams localize one master video into dozens of languages with one-click translation. Over 50,000 companies use it, including a large share of the Fortune 100.
