Kalyvox

What it does

Done-for-you service

PartlyYou configure and run the software yourself on Solo and Pro, where onboarding is self-service; only the Business plan adds assisted onboarding and a dedicated account manager, and even there the vendor is not running call flows as a service.Business extends the setup with unlimited users, numbers on request and dedicated support.kalyvox.ai/en/pricing ↗

How much it does unattended

Runs autonomously

YesThe assistant completes an inbound call end to end without a person on the line: it greets, qualifies, then transfers, offers a calendar slot or promises a callback, and delivers a ticket afterwards.When the reason calls for it, the call is transferred to the right person. Otherwise the assistant offers a slot from your calendar or promises a…kalyvox.ai/en/features ↗

Agent permissions

YesWhat the assistant may do is bounded by configuration: call reasons, questions, transfer rules and business information you enter, and the vendor publishes deliberate limits including refusing to answer outside that scope or to place outbound calls.The assistant shares only what you entered. On a question outside that scope it says so and passes the request on, rather than inventing an answer.kalyvox.ai/en/features ↗

Not established: Multi-agent

Which models it runs on

GPT

PartlyThe only model-vendor disclosure anywhere on the site is a sub-processor entry naming OpenAI for voice processing and transcription; there is no plan row, docs page or settings screen that offers GPT as a selectable model, so this is a supply-chain fact rather than a supported-model claim.OpenAI / AI providers – Voice processing and transcription (with anonymisation)kalyvox.ai/en/privacy ↗

Model choice

NoThe agent-configuration guide enumerates exactly what a customer may change about the assistant's identity — name, voice and response style — and a model or provider choice is not among them anywhere in the dashboard documentation.Name: give your assistant a name (default is Kali). Voice: choose from the available voices in settings. Response style: short, detailed,…kalyvox.ai/en/help/configurer-mon-agent ↗

Where you use it

In a browser

YesA hosted web dashboard is the main working surface on every plan: tickets, transcripts, summaries, filters, statistics and all agent configuration live there.Every call produces a transcript you can read in the dashboard. You choose how long it is kept and can request deletion at any time.kalyvox.ai/en/features ↗

Whose machine it runs on

Self-hosted

NoKalyvox is delivered only as a hosted service: the privacy policy places the database, telephony and payments with named sub-processors on AWS, Twilio and Stripe, and no self-hosted or bring-your-own-infrastructure option appears on any plan or docs page.Supabase Inc. – Hosting and database (Singapore / AWS EU) Twilio Inc. – Telephony and virtual numbers (United States, Standard Contractual Clauses)kalyvox.ai/en/privacy ↗

What it costs to run

How it meters

YesBilling is a fixed monthly subscription chosen by team size plus metered voice usage at €0.19 per minute of actual assistant conversation time, with no prepaid minute bundle and the same rate on every plan.Usage billing is the same for Solo, Pro and Business. Only actual assistant conversation time is counted.kalyvox.ai/en/pricing ↗

Free tier

PartlyYou can start without talking to sales or entering a card, but only for seven days: there is no standing free plan, and after the trial you either pick a paid plan or the account pauses.Every new account gets a 7-day free trial. No credit card is required to start. At the end of the trial, pick a plan or let the account pause.kalyvox.ai/en/help/facturation-et-abonn… ↗

API access

PartlyThere is a documented public REST API with bearer keys, ticket endpoints, cursor pagination and a ticket.created webhook, plus a public OpenAPI 3.1 spec — but key creation is only offered from the Pro plan upwards, so Solo customers cannot drive it from their own stack.The API is included from the Pro plan. On lower plans, key creation is not offered in Settings > Integrations.kalyvox.ai/en/help/api-kalyvox-zapier ↗

MCP server

PartlyAnother AI can query Kalyvox through the ChatGPT connector, included from Solo, but it is read-only and scoped to authorised data categories; the vendor documents no MCP server, and its own REST API is the only other programmatic route.Never editable from ChatGPT: the connection is read-only.kalyvox.ai/en/integrations/chatgpt ↗

Buying it for a team

A company can buy it

YesIt is sold to businesses rather than individuals: prices are quoted excluding tax, plans scale by users and numbers, invoices sit in the dashboard, and the Business plan is bought through a sales contact.More users, custom numbers and dedicated support.kalyvox.ai/en/pricing ↗

Seat model

YesSeats are the main plan differentiator with a hard ceiling on the lower tiers: one user on Solo, up to five on Pro, unlimited on Business, and the seat count does not change the per-minute usage rate.Solo covers one user and one number. Pro adds up to five users, SMS alerts, Zapier and priority support.kalyvox.ai/en/pricing ↗

Pooled budget

YesUsage is metered at workspace level, not per user: all assistant conversation time accumulates across the month against one bill at the same rate, and no per-seat minute allowance exists on any plan.Only time actually spent in conversation with the assistant is counted and accumulated across the month.kalyvox.ai/en/pricing ↗

Admin controls

PartlyAdmins constrain behaviour through roles and permissions, system instructions, transfer rules and the data scope shared with ChatGPT, but the vendor documents no policy engine, approval workflow or spend control.Manage your team with roles and permissions adapted to each profile.kalyvox.ai/en/features ↗

Audit log

PartlyRequests made through the ChatGPT connector are logged so usage can be audited, and connection logs are retained twelve months, but no general administrative audit trail of dashboard or configuration changes is described.Requests made through the connection are logged on the Kalyvox side, so usage can be audited.kalyvox.ai/en/integrations/chatgpt ↗

What happens to your code

Opt out of training

PartlyCall data is used to improve the vendor's AI algorithms in anonymised form under legitimate interest, and the policy offers a GDPR right to object rather than a product setting; no dashboard toggle or contractual opt-out is documented.Improving our AI algorithms (in anonymised form)kalyvox.ai/en/privacy ↗

Data residency

PartlyThe vendor is a French company marketing European hosting, but its own sub-processor list puts the database at Supabase on Singapore / AWS EU and telephony with Twilio in the United States under Standard Contractual Clauses, so data does leave the EU.Some of our sub-processors are located outside the EU (United States). These transfers are framed by: • The European Commission's Standard…kalyvox.ai/en/privacy ↗

Getting out

YesData comes out in CSV from the dashboard and in a structured JSON/CSV portability request, deletion is available on request, and there is nothing to forfeit on exit because usage is billed after the fact with no prepaid minute bundle.Export your data in CSV format for reporting and analysis.kalyvox.ai/en/features ↗

Certifications

PartlyGDPR compliance is claimed directly with a named DPO contact, AES-256 and TLS 1.3 encryption and regular penetration tests, but the only certification cited is ISO 27001 held by the AWS hosting layer; no SOC 2 or Kalyvox-held ISO certificate is published.Hosting on AWS infrastructure certified ISO 27001kalyvox.ai/en/privacy ↗
