Agentic Index
Delight.ai vs Sinch (2026)
Both grew out of messaging infrastructure and now sell AI agents for customer service, with opposite views on how much the agent decides. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Sendbird's Delight.ai runs agents that keep a living memory of each customer across chat, email, SMS, WhatsApp, social and voice, reach out when a customer goes quiet, and take on long running issues end to end. Operations teams edit refund thresholds and escalation rules in an Actionbook editor, and releases go through staging, test suites built from real conversations and a rollout that starts at ten percent of traffic. Sinch's Chatlayer, sold as Agent Builder, builds bots as designed flows where an intent engine picks the path and API steps, code actions and Zendesk or Salesforce actions do the work. Choose Sendbird when the agent lives inside your own app and should improve through staged releases, and Sinch when you want predictable flows and ready templates.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Delight.ai and Sinch are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 955 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose Delight.ai if
- The agent should live inside your own iOS, Android or web app through SDKs, next to the chat and voice you already run.
- Each change should go through staging, pass or fail tests built from real conversations, and reach ten percent of traffic first.
- Operations staff should edit refund thresholds, escalation logic and tone without an engineering ticket.
- An operator should be able to pause, redirect or stop any flow at once.
Choose Sinch if
- Every step should be designed in advance on a visual canvas.
- You want to start from a working template for banking, returns, bookings or lead generation.
- You want to choose the OpenAI model behind generated replies and use your own key after the first 100 messages.
- WhatsApp, RCS and SMS already run through Sinch, and bots should sit on the same Conversation API.
- Knowledge base answers should cite the file, page or URL they came from.

Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
Delight.aiIntegrations & Tool Calling Delight.ai integrates with Zendesk, Salesforce and Freshworks for live agent handoff, with Salesforce also supported as a knowledge source and third-party knowledge base integration so the agent can surface the right information in real time. Agents take action as well as answer, and Trust OS logs every tool call. On the channel side the agent reaches customers through in-app chat, web, email, SMS, WhatsApp and social, all built on Sendbird's communications platform, and an AI Agent Integrations page carries the connector set.

SinchIntegrations & Tool Calling Action blocks connect a bot to outside systems in three ways. An API step sends requests to any HTTPS endpoint with any of the five standard HTTP methods, authenticates with basic auth or a bearer token, passes session variables in the query or body, and can route the conversation to the next block named in the response. Code actions run JavaScript that calls external services and writes the results back to the session. Native app steps create, find and update Zendesk tickets and users, create Salesforce contacts, accounts and cases or run SOQL queries, and connect Freshdesk, Topdesk, Gmail and Intercom. In a banking bot, an API step can post a money transfer's amount, destination and account type to the customer's back end in the middle of a conversation.

Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |
||
|
Delight.aiWorkflow Orchestration Agent Steward takes full ownership of complex, long-running customer issues end to end instead of answering and closing, and its agents understand intent, hold context, take action and adapt, resolving complex issues and escalating only when needed. Behavior comes from a customer-authored actionbook holding rules such as refund thresholds and escalation logic, which Openbook renders as a visual flow through complex branching. Above the individual case, Zero-Touch Improvement runs a closed loop in which observability catches an issue, control tests the fix and oversight holds it to policy, in a graduated system that moves from human-guided to autonomous.

|
SinchWorkflow Orchestration Bots run as flows on a visual canvas, where each block sends a message, collects input, checks a condition or runs an action, and go to connections move the conversation between blocks and flows. Condition blocks branch on variables, an API response can name the next block, events start a flow when a variable changes or the user goes quiet, and delay and pause steps hold the conversation. Flows can be reused across a bot and published one at a time. The intent engine picks the flow and the designer sets every step inside it, so the sequence is fixed when the bot is built. Running two bots in one conversation takes the web widget or a custom proxy over the webhook channel. Sourcedocs.chatlayer.ai/navigation/bot-builder/flowsread 2026-10-11 |

Triggers & Channel Coverage How agents wake up and where they work: schedules, webhooks, message events, CRM events, inbox events, chat, email, voice, and collaboration tools. |
||
|
Delight.aiTriggers & Channel Coverage Channels are in-app chat, website, email, SMS, WhatsApp, social messaging and voice, all carried on Sendbird's communications platform, with context following customers between channels instead of restarting. Omnipresent agents are always on, always aware and always personal, and they start conversations themselves, anticipating needs before an issue forms and re-engaging when a customer goes quiet or switches channel. Voice 2.0 adds multilingual real-time outbound calling. SourceDelight.ai Omnipresent, Voice AI Agent and AI agent platform pagesread 2026-09-05 |

SinchTriggers & Channel Coverage Conversations arrive through the Sinch Conversation API on WhatsApp, RCS, SMS, MMS, Messenger, Instagram, Viber, Telegram and LINE, through the Web V2 widget, through a webhook channel for any custom front end, and through phone lines for voicebots. Inside a conversation, events start a flow when a variable changes, when the user stays silent for anywhere from 1 to 1,440 minutes, or when a WhatsApp Flow is completed. Outside systems can also push into a live conversation through the REST API, sending messages, setting session data or triggering a specific block for a given user, so a back end event can move a conversation forward.

Delight.aiKnowledge Grounding & RAG Delight.ai integrates third-party knowledge bases so the agent can find and surface the correct information in real time, with Salesforce supported as a knowledge source and Freshworks and Zendesk connected alongside. Building an agent works like onboarding a team member, transferring knowledge to it through the supervisor dashboard, and the actionbook holds the authored rules the agent answers within. Trust OS detects factual errors and off-policy responses automatically, and the review-and-grade surface scores knowledge accuracy.

SinchKnowledge Grounding & RAG Knowledge base AI keeps a store of the customer's content and generates short answers from it. Content goes in as PDF files, CSV question and answer files, single web pages or entire domains, and tags limit which content a given flow searches. Each answer comes back with the retrieved passages, the source file or URL and the specific page it came from, so a bot can offer a link to the source. When nothing matches, a no findings path sends the user to another block instead of inventing an answer, and a non generative mode replies only with the exact answers in a CSV file. The feature is free up to 50 questions a month, with higher volumes through sales. Sourcedocs.chatlayer.ai/navigation/knowledge-base-airead 2026-10-11 |

Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
Delight.aiMemory & State Persistence The Agent Memory Platform, sold as its own product, is the intelligence layer that gives agents a living memory and a business brain, connecting what the agent remembers about each customer with what the business is trying to achieve. Agents absorb signals from every conversation and action to form an evolving understanding of the customer that goes beyond static CRM data, and context is kept as a customer moves between chat, SMS, email and voice so nobody repeats themselves. The agent remembers every interaction, and continuity carries across separate conversations as well as within one, unlike conventional chatbots that lose history the moment a session ends. SourceDelight.ai Agent Memory Platform and AI agent platform pagesread 2026-09-05 |
||
|
SinchMemory & State Persistence Each user's session holds what the bot has learned about them, including variables it collected, API results and the last intent, and one session can span several conversations. Sessions expire after 30 days without activity by default, a period Enterprise customers can change per bot and separately for the draft and live versions. Through the REST API a team can read a session, write to it, delete it for one conversation or delete all data for one user. Bots use saved variables to recognize returning users and reuse earlier answers, such as a traveler's usual route. Persistence depends on the channel, and the web widget keeps variables for one visit unless users are identified. Variables marked sensitive stay out of conversation history.

Human Oversight & Guardrails Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls. |
||

Delight.aiHuman Oversight & Guardrails Trust OS has kill switch and escalation controls that pause, redirect or kill any AI flow instantly, with one-click escalation to a human agent and role-based access control so the right people own the right agents. Policy is customer-authored through the Actionbook Editor, which lets operations teams edit refund thresholds, escalation logic and tone in real time with no code and no engineering ticket. Hallucination and unsafe content detection runs automatically, flagging factual errors, off-policy responses and safety violations before customers see them, and a review-and-grade surface lets people score responses and flag outliers against the customer's own standards. Handoff to a person runs through the Zendesk, Salesforce and Freshworks integrations. Oversight comes through authored policy, automatic detection and interruption, not a sign off on each action before it is sent. SourceDelight.ai Trust OS and AI agent platform pagesread 2026-09-05 |

SinchHuman Oversight & Guardrails A Send to offload provider step hands a conversation to a person in Sinch Contact Pro, Genesys Cloud, Salesforce Service Cloud, Zendesk Chat, Help Scout or any platform behind an offloading webhook, with the transcript and collected variables passed along. The bot keeps answering until an agent accepts, then pauses until the agent sends the user back. Designers choose where handover happens, typically on request, after repeated not understood turns or after two unsatisfactory knowledge base answers. Generative features can be switched off per bot, and a split between draft and live versions keeps unpublished changes away from customers. No step lets a person approve an action or a reply before the bot sends it. Sourcedocs.chatlayer.ai/integrateandcode/human-offloading-live-chatread 2026-10-11 |

Delight.aiObservability & Auditability Trust OS logs everything for tracing, and Openbook logs every conversation, every decision and every tool call for review, with no black boxes. Openbook also renders the agent's actionbook as a visual flow, so an operator can follow the logic behind a decision. Low CSAT Analysis sorts every conversation scored one or two into one of five failure types before anyone opens it, and Thinking Messages show a status for each tool call during the run, so the reasoning is visible as it happens as well as afterward.

Delight.aiTesting, Debugging & Optimization Every change is tested before it touches a customer, with staging, real-conversation test suites, gradual rollout and A/B data, so a deploy comes with evidence. Staging environments mirror production with real integrations and policies. Test Upgrade builds test cases from real conversation IDs, organizes them with labels, shares sets across environments and returns consistent pass/fail results. Gradual rollout ships to ten percent first, and A/B testing runs two versions head to head for hard data on resolution rate and CSAT before committing.
