In their own words
Tars
Tars provides AI agents for customer support and customer acquisition, with a no-code builder for creating agents without writing code. Agents can retrieve answers from Knowledge Bases trained on sources such as websites and PDFs, use tools, branch according to user intent, and combine retrieval with multi-step workflows. Tars describes deployment across web, WhatsApp and email, with conversations carried across channels. Built-in integrations connect agents to customer experience technology stacks, and an API Integration component can fetch or submit data in real time. Tars states compliance with GDPR, ISO, SOC 2 and HIPAA. The Freemium plan includes 50 conversations per month, five Knowledge Bases, basic LLM models, community support and one month of data retention. When the monthly conversation allowance is used, the agent stops until the customer upgrades. A conversation counts all messages between an agent and user within 24 hours. Premium costs $499 a month and includes advanced LLM models, 20 Knowledge Bases and 12 months of data retention. Premium offers live chat support; Enterprise includes a dedicated account manager.
Voiceflow
Voiceflow is a platform for building, testing, deploying, and monitoring chat and voice agents across channels and languages. Its builder combines agentic playbooks, deterministic workflows, shared instructions, and guardrails. Teams can review transcripts and call recordings, run evaluations and tests, and track analytics. Agents can reach users through a native chat widget, mobile apps, phone calls, SMS, or custom interfaces built with the Conversations API. Native integrations include Zendesk, Salesforce, HubSpot, Shopify, Airtable, Google Sheets, Gmail, and Twilio. Agents can also connect to external REST APIs, custom Functions, and MCP servers. Teams can choose from major LLM providers or bring their own model. Voiceflow says customer data is not used to train AI or machine-learning models and integrated model providers are configured for zero data retention. Its security information describes encryption at rest with customer-managed keys and encryption in transit using TLS and mTLS. The company was founded in 2019. Agencies and partners have a free-trial plan with usage-based billing; business pricing is available on request. Support includes implementation that can be self-serve or fully managed.
