Vocily vs Bolna
Bolna sells voice agents at one bundled per-minute rate in US cents, with a bring-your-own-keys option. Vocily prices each part of the call separately in rupees and runs the same agent on phone, WhatsApp and web.
The short version
How Vocily and Bolna differ
Bolna bundles speech, model, voice and telephony into one rate: 6.00¢/min on pay-as-you-go (about ₹5.52 by their own conversion), falling to 4.51¢ at volume. Vocily starts at ₹3.10/min, with telephony free on your own Plivo or VoBiz account or ₹0.40/min on a number rented from us, so most Indian calling costs less. Bolna is the simpler bill; Vocily is the cheaper one and adds WhatsApp and web chat.

Which to choose
The right fit depends on what you need

Common questions
What teams ask before they switch.
For most Indian calling, yes. Vocily starts at ₹3.10/min, plus ₹0.40/min if you use a number rented from us (nothing if you bring Plivo or VoBiz). Bolna's pay-as-you-go rate is 6.00¢/min, about ₹5.52, with telephony included. Choosing premium models on Vocily, such as ElevenLabs voices, raises our rate; the pricing page shows the exact total for any combination.
