Tabbly vs Helo.ai side-by-side
Public figures, October 2026. “Loaded minute” means speech models + telephony when the vendor splits them. Re-check the vendor before you buy.
| Dimension | Tabbly | Helo.ai |
|---|---|---|
| Best for | Teams that want to launch inbound/outbound voice agents in Indian and global languages without assembling STT, LLM, TTS and telephony themselves | Regulated enterprises (BFSI, utilities) that already buy Indian CPaaS and want AI on SIP/PSTN/WebRTC with a sales-led delivery |
| Not ideal for | Teams that need HIPAA/BAA as the primary buying reason, or a fully outsourced human+AI BPO | Startups that need self-serve signup, a public rate card and an agent this afternoon |
| HQ / centre of gravity | India, with US data-residency option | India (Helo.ai by Vivaconnect, est. 2001) |
| Product type | No-code AI voice-agent platform | Enterprise CPaaS + Helo Voice agents |
| Price / minute (public) | From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month | Custom quote only — no public per-minute on Helo Voice |
| Languages | 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages | Hindi, English and regional Indian languages on the same agent; Helo materials also cite 12–22+ language figures depending on product (Convo vs IVR pages) |
| Latency (public) | India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. | Carrier-grade Indian infrastructure; no public millisecond SLA on the voice-bot page |
| Data residency | India / USA data residency (stated on tabbly.io) | Data localised in India on Helo infrastructure; on-prem / private cloud offered for regulated buyers |
| Builder | No-code agent builder plus APIs; campaigns, recordings, analytics | Enterprise configuration; Helo Convo is prompt-to-agent for chat. Voice is sold as an organisation-wide phone channel. |
| Telephony | 50+ countries, local numbers including +91, unlimited concurrency on published plans | Native SIP, WebRTC, PSTN; mix carriers by region without rewriting agent logic |
| Concurrency | Unlimited on published product pages | Horizontal scale, no seat-licence ceiling claimed |
| Billing | INR or USD, exact seconds, self-serve credits | INR enterprise MSA |
What Helo.ai actually is
Helo.ai is what “India-first” looks like at bank scale: 25 years of traffic, DLT, and private infrastructure. That is a different buyer than Tabbly’s self-serve voice-agent user. Fair take: Helo is stronger as an enterprise communications fabric; Tabbly is stronger as a specialised voice-agent product with a public rate card.
Where they are strong
- Deep India enterprise trust (banks, utilities) and TRAI/DLT heritage.
- True carrier mixing and on-prem options.
- Omnichannel (WhatsApp, RCS, SMS) next to voice.
What to watch
- No self-serve price — procurement cycle.
- You are buying a CPaaS relationship, not a $0.05/min product.
- Overkill for a 10-seat sales team that just needs outbound AI.
Price per minute — the loaded number
Tabbly’s published card is From $0.05/min ($0.04/min on large committed volumes); India list ₹6.80/min PAYG or ₹5.10/min from 5,000 min/month. Tabbly bills to the second. Indian numbers are listed around ₹450/month on the enterprise calculator; telco on India PSTN is a small add-on (about 0.75 paisa/min). Public voice-agent rates are $0.05/min PAYG, $0.04 committed, India ₹6.80 / ₹5.10 from 5k minutes.
Helo.ai publishes Custom quote only — no public per-minute on Helo Voice. 25 years of Vivaconnect/Helo enterprise messaging. Helo Convo (chat) mentions one platform fee plus Meta rates at cost. Voice is scoped in an MSA.
Finance teams should model three lines: (1) the vendor’s AI/hosting meter, (2) STT/LLM/TTS if those are BYO, (3) PSTN. A ₹3 or 6¢ headline that excludes the carrier is not cheaper than a ₹5.10 committed Tabbly minute until you add telco. Conversely, Tabbly is not automatically cheaper than VoiceCallingAI’s ₹3 pack or Sarvam’s ₹3.50 model-included PAYG on pure India traffic — those vendors can win on rupees. Tabbly’s commercial case is seconds billing, language coverage, and India + export on one invoice.
Languages
Tabbly: 50–60+ languages, including Hindi, Hinglish, Tamil, Telugu, Kannada, Marathi, Gujarati and major global languages
Helo.ai: Hindi, English and regional Indian languages on the same agent; Helo materials also cite 12–22+ language figures depending on product (Convo vs IVR pages)
For India, the test is not “do they list Hindi.” It is Hinglish code-switch, South Indian languages on the same agent, and whether English/Arabic/Spanish are available if you later call Dubai or Singapore. Helo.ai is a 12–22+ language story. Tabbly is a 50+ language story with Indic as a first-class set, not an add-on.
Latency and data residency
Latency. Tabbly: India and US residency options so audio does not have to hairpin every turn through a US-only region. Tabbly does not publish a single lab millisecond figure. Helo.ai: Carrier-grade Indian infrastructure; no public millisecond SLA on the voice-bot page Ignore US lab milliseconds for a Jio caller. Ask for a recorded +91 round-trip: connect-to-first-word, barge-in, and time-to-interrupt.
Residency. Tabbly: India / USA data residency (stated on tabbly.io) Helo.ai: Data localised in India on Helo infrastructure; on-prem / private cloud offered for regulated buyers DPDP is a contract line, not a homepage adjective. If you are regulated, get the region and subprocessors in writing.
Builder, telephony, concurrency
Tabbly ships No-code agent builder plus APIs; campaigns, recordings, analytics, 50+ countries, local numbers including +91, unlimited concurrency on published plans, concurrency unlimited on published product pages.
Helo.ai ships Enterprise configuration; Helo Convo is prompt-to-agent for chat. Voice is sold as an organisation-wide phone channel.. Telephony: Native SIP, WebRTC, PSTN; mix carriers by region without rewriting agent logic. Concurrency: Horizontal scale, no seat-licence ceiling claimed.
Startups that need self-serve signup, a public rate card and an agent this afternoon
The honest split
If you are Kotak/HDFC-shaped and already standardised on Helo, adding Helo Voice keeps vendor count at one. If you are a growth-stage company that needs agents, Indian + global languages, and published $0.05 / ₹5.10 economics, Tabbly is the shorter path.
Buying checklist
- Get a loaded-minute quote (models + India PSTN + number rental), not a hosting-only headline.
- Run 20 Hindi and 20 English live calls on +91. Score completions, not demo polish.
- Confirm language list against your actual states — Tamil and Telugu drop off many “Hindi + English” tools.
- Write down data region, retention, and whether recordings leave India.
- If you might call the US, UK, SG or AE later, do not lock into an India-only vendor without an exit.
