In their own words
Amazon Lex
Amazon Lex lets application builders create conversational interfaces that respond to natural-language voice or chat input. It combines automatic speech recognition for voice with natural language understanding for voice and text interactions. Builders can use a visual flow builder and AI bot generation. The Automated Chatbot Designer analyzes conversation transcripts and proposes an initial design with intents and slot types; Test Workbench supports creating test sets and reviewing results. For FAQ responses, an intent can query an authorized knowledge source and foundation models from Amazon Bedrock. Bots can be deployed on mobile devices and chat services including Facebook Messenger, Slack, Kik, and Twilio SMS. AWS integrations include Lambda for backend logic, Cognito for authentication, Polly for text-to-speech, and Amazon Connect for contact centers. Lex is available for Android, iOS, web, and API use. Text and speech requests use pay-as-you-use pricing, with no upfront commitment or minimum fee in the listed examples. Automated Chatbot Designer training time is listed at $0.50 a month, with pricing described as per minute of training time. The AWS Free Tier is available for six months after account creation, with credits subject to stated eligibility and expiry terms.
Chatbase
Chatbase provides customer-facing AI agents for support, sales, and product guidance across chat, email, and voice. Teams can build, test, deploy, and improve agents without code. Agents can use help centers, files, links, Q&As, Notion pages, tickets, and product data; plain-language procedures and actions let them look up information or make changes in connected systems. Testing tools include customer-scenario simulations, saved regression tests, and conversation traces. Listed integrations include Salesforce, Zendesk, Freshdesk, Gorgias, Help Scout, HubSpot, Intercom, Shopify, Slack, Zapier, and Twilio. Chatbase says customer data is encrypted in transit and at rest, is not used to train models, and is accessible only to the customer's AI agent. The Free plan includes 50 message credits per month and one member, but agents are deleted after 14 days of inactivity. Hobby costs $40 a month for 700 credits; Standard costs $150 a month for 4,000 credits; Pro costs $500 a month for 15,000 credits. Hobby, Standard, and Pro have a 7-day trial. Developer tools include a JavaScript embed, REST API, CLI, and Android and iOS SDKs.
