Voker
Also known as: Voker, Voker.ai, Invoke Labs
Agent analytics platform whose drop-in SDK records every agent call and automatically annotates user intents, corrections and resolutions, reporting resolution and correction rates by agent version.
Voker is an agent analytics platform for teams running AI agents in production. A drop-in Python or TypeScript SDK swaps in for the OpenAI, Anthropic, Gemini or Vercel AI SDK client, or a REST API covers other stacks, and every model call becomes an event tied to an agent version and an end user, with its messages, system prompt, response and tool calls, grouped into sessions.
Voker automatically annotates each event with what the user was trying to do, where they had to correct the agent, and whether the intent was resolved, then groups intents and corrections into categories and reports resolution rates, correction rates and token cost by agent and agent version, so teams can see how a prompt or model change affected each kind of request. Session, agent and person summaries cut down on reading logs. Smart Skills, in beta, generate short prompt amendments from corrections and errors, flag skills that raise cost or correction rates, and version the agent each time one is added or removed.
Voker is aimed at product, engineering, data and leadership teams with production agents handling high conversation volume. Plans run from free at 2,000 events a month to $400 a month for two million events, all with unlimited seats, and an Enterprise plan adds self-hosted deployment, SSO and custom retention.

Integrations
A lightweight, provider agnostic SDK instruments any agent across frameworks, with dedicated wrappers for the leading model providers. It automatically captures events including user messages, assistant messages, and tool calls, tracking both the tools available to an agent and the tools it actually used, and correlates conversational data with the user data teams already collect.
In practice
A hotel booking agent starts getting questions about the attached cafe and restaurant. Voker surfaces that pattern across conversations, so the product team knows to add menu and reservation info rather than guessing.
A recent prompt change quietly breaks an agent's date handling. Voker's abnormality and correction detection catches it in the data before users flood Slack with complaints.
An executive asks how much revenue the agent drives. Voker's Outcome Correlation Engine ties agent behavior to conversion and retention using data the team already collects, so the PM can answer without an engineering ticket.

| Integrations & Tool Calling | Partial |

Voker wraps the OpenAI, Anthropic, Gemini and Vercel AI SDK clients and works with LangChain and CrewAI to capture a customer's agent calls and tool calls, and its people API ties events to user data the customer already holds. These bring the customer's agent data in; the agent calls its own tools, and no integration through which an agent reads or writes a real system is described.

Agents are measured after the fact, through annotations, rates and session summaries, and Voker's human reviewer settings govern whether it removes a Smart Skill without review.

| Observability & Auditability | Full |

Every LLM call or wrapped execution becomes an event tied to an agent version and a person, and Voker stores the ordered messages including user inputs, system prompts and model responses along with the agent's tool calls, groups events into sessions for a whole conversation or workflow, and lets teams drill from the dashboard into individual sessions to debug them. Data is kept 30 days on the free plan, 90 days on Starter, one year on Agent First and a custom period on Enterprise.

| Memory & State Persistence | Not documented |

For analytics, Voker stores events, sessions and person profiles, and it tracks long-running conversations as sessions.

Annotation runs automatically on every event Voker receives, tagging intents, corrections and resolutions, and Voker generates a Smart Skill for an agent on its own once it reaches a confidence threshold that the prompt is not handling a set of tasks, based on user corrections and logged errors.

Each event is labeled with the user's intent, any correction and whether the intent was resolved, and Voker reports resolution and correction rates per intent category, filters them by agent version so teams compare how a prompt or model change affected each intent, and its Smart Skills generate prompt amendments from corrections and errors, flag skills that raise cost or correction rate, and version the agent each time.

The Agentic Index coverage score grades every vendor Full, Partial or Not documented against the same 14 buyer facing capabilities, from public evidence only. Each capability links to how all vendors in the index score on it. How this evidence is graded
Pricing
Free · paid from $80/month
Monthly plans by event allowance, where an event is a user message, assistant message or tool call (about 15 per conversation on average); unlimited seats on every plan; Enterprise custom
What is public
The staged plan structure and a free tier are public, with the Product Hunt listing citing up to two thousand events per month free. Events are defined as user messages, assistant messages, and tool calls. Exact paid rates were not fully retrievable.
Billing mechanics
Self serve staged plans from a free tier upward, billed on events. Start free and scale as agents grow, with team invites. The company targets agents already in production handling at least one thousand conversations per month.
Cost watchouts
Every user message, assistant message and tool call counts as an event, about 15 per conversation, so a busy or tool-heavy agent moves up plans faster than conversation counts suggest; self-hosting and SSO need Enterprise.
Variable cost rationale
Cost steps up by plan as event volume grows, and events count every message and tool call, so spend tracks agent conversation and tool-call volume.
Additional watchouts
Because billing is event based and an event includes each tool call, agents with heavy tool use will accrue events faster than a per conversation view would imply.
Sales call required
Mixed (some tiers require a call)
Free / trial
Free plan at $0 a month with 2,000 events and 30 days of retention
Lowest paid plan
Starter, $80 a month for up to 20,000 events and 90 days of retention
Commercial notes
Self-serve plans from free to $400 a month with unlimited seats, and an Enterprise plan through sales for self-hosting, SSO and custom retention.
Key ambiguities
Overage handling above a plan's event allowance is not stated on the pricing section read.
Missing data
Exact paid tier prices and per event or event allowance details above the free tier were not retrievable from fetched pages.
