Start free with guest credits, then choose packs or a subscription that fits how often you translate.
Cosmo separates guest trial credits, subscription credits, and pack credits so usage is always transparent. Subscription credits are used first, then pack credits - your guest trial balance stays separate. You can have one active subscription at a time; pack credits stack on top.
"Used Cosmo in Japan for a whole week. Hands-free mode worked perfectly in restaurants - just set the phone on the table and both of us could talk naturally. Genuinely incredible."
"I work with suppliers in China and this has completely changed how I run meetings. Press & Hold is great for noisy conference rooms - precise, clean, no background noise."
"The credit system is exactly right. I travel a few times a year and don't want a subscription - just grab a pack before each trip. Simple, affordable, and it always works."
General-purpose translation tools do a lot of things. Cosmo does one thing well: live, two-way spoken conversations between two people.
