Talknex is an enterprise-grade platform for deploying conversational AI phone agents. You configure an agent with a persona, voice, and system prompt; connect a phone number via Twilio; and the agent autonomously handles inbound and outbound calls — booking appointments, qualifying leads, and transferring to humans when needed.
No. The full dashboard — agent configuration, knowledge base uploads, call analytics, and phone number management — is entirely no-code. Developers who want to go deeper can use our REST API, WebSocket streaming endpoints, and webhooks.
Most teams are live in under 15 minutes. Sign up → create an agent (paste a system prompt and pick a voice) → provision a phone number → your agent starts answering calls. No infrastructure to manage.
Yes. Every agent has a built-in browser-based call tester so you can run a full conversation before attaching a real number. You can also use our REST API to simulate calls programmatically in your CI pipeline.
Yes. You can trigger outbound calls via the dashboard or API — useful for follow-ups, appointment reminders, or lead qualification campaigns. Outbound minutes are billed the same as inbound minutes.
Talknex agents can understand and speak 30+ languages out of the box through our Deepgram STT and ElevenLabs TTS integrations, including English, Spanish, French, German, Portuguese, Arabic, Hindi, Mandarin, and many more. Custom language models are available on Pro and Custom plans.
No. We pipeline three leading AI providers — Deepgram for streaming speech-to-text, a fast low-latency LLM for reasoning, and ElevenLabs for text-to-speech — so the agent responds with natural prosody and emotion. Most callers cannot distinguish it from a human within the first minute.
A caller hears a reply in about a second — the natural pace of a turn-based phone conversation, since the agent waits for the caller to finish speaking. We keep it snappy by pipelining streaming STT, LLM, and TTS: audio starts playing before the LLM finishes generating.
Yes. Deepgram VAD (voice activity detection) detects when the caller speaks over the agent and immediately halts TTS playback. You can tune interruption sensitivity per-agent — from highly interruptible (conversational style) to low sensitivity (good for complex explanations).
Yes — voice cloning is available via ElevenLabs on Pro and Custom plans. Provide ~10 minutes of clean audio and you'll have a custom voice model attached to your agent, so you can ship your brand voice at scale.
Calls run over Twilio's carrier-grade PSTN infrastructure. If the WebSocket session drops, the call gracefully disconnects and the partial transcript is flushed to the database immediately. The agent will not attempt to reconnect mid-call — the caller must dial back.
Talknex has three plans. Starter is $80/month with 300 minutes, 1 agent, and 1 phone number. Pro is $200/month with 1,000 minutes, 3 agents, 3 numbers, live supervision, integrations, and campaigns. Custom lets you pick agents, minutes, and features for an instantly priced plan billed by invoice. Every plan starts with a free trial, and secure checkout is powered by Safepay.
Each plan is one flat monthly price: Starter $80, Pro $200, and Custom from $80 depending on your configuration. There are no per-minute charges on top of your plan and no overage fees — included minutes are a hard cap, so your bill never exceeds your plan price.
Yes — spend control is built into the model. Every plan is a fixed monthly price with a hard cap on included minutes. When the cap is reached, calls pause until your next billing cycle or an upgrade; you are never billed extra.
Bringing your own Twilio account is available on Custom plans. Your Twilio usage then bills directly to your Twilio account while Talknex bills your flat plan price. Starter and Pro include Talknex-provisioned numbers, so no Twilio account is needed.
Plans are billed monthly — Starter at $80/month, Pro at $200/month, and Custom by monthly invoice. There is no annual contract or lock-in; you can cancel anytime and your plan stays active until the end of the billing period.
Native integrations exist for Salesforce and HubSpot. After each call, transcripts, sentiment scores, and call outcomes are synced as activities. Contact and lead records are created automatically if the caller's number is new. You can connect other tools via Zapier, Make, or webhooks.
Yes — the built-in book_appointment tool writes directly to Google Calendar or Microsoft Outlook (via OAuth). The agent checks your real availability, proposes slots, confirms with the caller, and sends an invite with a meeting link. No back-and-forth email required.
Yes. There are native Zapier and Make triggers for call completed, new lead created, and appointment booked events. You can chain these to 5,000+ apps without writing code — Slack alerts, Airtable rows, Google Sheets, and more.
Calls run over Twilio's carrier-grade PSTN infrastructure using numbers provisioned inside Talknex — 1 number on Starter, 3 on Pro. Custom plans can connect their own Twilio account and number inventory. The same agent config handles inbound and outbound calls, and the voice pipeline adapts automatically.
All data is encrypted in transit with TLS 1.3 and at rest with AES-256. Transcripts, recordings, and vector embeddings are strictly scoped to your organization — no data crosses org boundaries. We do not use customer data to train shared AI models.
Talknex is architected to be HIPAA-ready and we sign a Business Associate Agreement (BAA) with Custom plan customers. If you are in healthcare, contact our sales team to discuss your specific PHI handling requirements before going live.
By default data is stored in the EU (Frankfurt). Custom plan customers can request US, EU, or APAC data residency at the org level. We are SOC 2 Type II in progress and GDPR-compliant for EU data subjects.
Yes — recordings and transcripts are your data. You can delete individual call records from the dashboard or bulk-delete via the API. Deletion is permanent and propagates to all storage layers within 24 hours.
A standard REST API under https://api.talknex.ai/v1. Auth is via Bearer tokens. Every resource — agents, calls, contacts, knowledge bases — has full CRUD endpoints with OpenAPI 3.0 docs available at /docs.
Yes — subscribe to a call's WebSocket stream and receive transcript deltas, sentiment events, and tool calls in real-time as the conversation happens. This is how our own dashboard renders the live call widget.
Configure a webhook URL in the dashboard and we POST signed JSON payloads to it on events: call.started, call.ended, transcript.final, appointment.booked, lead.created. Signatures use HMAC-SHA256 with your webhook secret so you can verify authenticity.
Yes. Define custom tool schemas (JSON Schema format) in the agent’s Developer tab. When the LLM decides to call a tool, Talknex POSTs the arguments to your webhook URL, waits for your response, and feeds the result back into the conversation — typically adding well under a second of round-trip.
Custom plans add dedicated infrastructure (no noisy neighbors), white-label capabilities, SSO/SAML, custom voice models, a dedicated success manager, SLA-backed support, a HIPAA BAA, and optional on-premise deployment. Build one on the pricing page for an instant estimate, or contact sales to provision the configuration you need.
Yes — on-premise and private cloud (AWS, GCP, Azure) deployments are available on Custom plans. We provide a Docker-based bundle with the full voice stack. Your data never leaves your network.
Yes. White-label removes all Talknex branding, allows custom domain and logo, and optionally white-labels the email sender domain. Resellers and agencies use this to power their own AI voice products.
