OmniDimension
Also known as: omnidim.io, OmniDim, Omni Dimension
OmniDimension is a platform for AI voice agents configured in plain text and deployed to phone numbers in 70+ countries, web calls, WhatsApp, email and SMS, with more than 1,000 voices in 90+ languages and strong Indian language coverage. Agents call any REST endpoint as an action, answer from knowledge bases and live web search, remember each caller across channels in memory pools, run bulk and dynamic campaigns, and plug into OmniWorkflows automations, with a REST API, Python SDK and an OAuth MCP server.
OmniDimension Inc., based in Milpitas, California, sells a self serve voice agent platform to businesses and agencies, with a large Indian customer base paying in rupees and verticals in real estate, healthcare, insurance, restaurants, finance, education and ecommerce, plus lead generation and collections. It names Vapi and Synthflow as rivals.
An agent is configured in sections of plain instructions with a welcome message, and its full configuration covers the transcriber, the language model, the voice, integrations and post call actions, with available LLM, voice, speech to text and text to speech providers listed through the API. Knowledge bases supply document based references, and a web search tool gives agents live internet access.
Custom API turns any REST endpoint into an action the agent can take mid call, a custom API transfer lets an outside system choose the number a call goes to, and prebuilt connectors cover Salesforce, HubSpot, Slack, Google Sheets, Omni CRM, GoHighLevel, Make, Zapier and n8n. Caller memory groups agents into memory pools that share what they remember about each caller across phone, web chat and WhatsApp, keeps six parts of a caller's memory, lets permitted users see exactly what agents are told, review every change and forget a caller permanently.
Bulk call campaigns run with retries and dynamic queues, dynamic campaigns take contacts in real time through a webhook API, WhatsApp supports agent replies, templates, broadcasts, in call template sends and WhatsApp calling, and OmniWorkflows builds visual automations from triggers, AI nodes that score and route, flow control and CRM nodes, with test runs and per node execution logs. Live call monitoring shows transcripts as calls happen, and post call actions deliver results to email, webhooks and CRMs.
Plans start free with about 20 minutes, then Starter at $20 a month (about 317 minutes at $0.063), Jump Starter at $60 (about 1,000 minutes at $0.060) with versioning, live monitoring and workflows, Growth at $200 (about 3,571 minutes at $0.056) with email and SMS channels, and Enterprise with volume rates down to $0.035 a minute; pay as you go top ups run from $0.063 down to $0.054 a minute, and agencies choose Reseller at $55 a month or the white label OmniRelay at $100. OmniDimension does not publish HIPAA, SOC 2 or PCI DSS certifications and says such deals go to sales, and no hosting region or private deployment is described.
OmniDimension fits developers, agencies and SMBs, especially in India, that want low per minute voice agents with real API tools, cross channel caller memory, campaigns and a full MCP and SDK surface. It fits less well for regulated buyers who need written compliance attestations or a choice of data region, or for teams that want a human approval step before agents act.

Integrations
Custom API actions call any REST endpoint mid call, and custom API transfer lets an outside system pick a call's destination. Prebuilt connectors and post call actions cover Salesforce, HubSpot, Slack, Google Sheets, Omni CRM, GoHighLevel, email and webhooks, with Make, Zapier and self hosted n8n for 6,000+ apps. WhatsApp Business, SMS, email and web search tool. REST API and Python SDK over agents, calls, campaigns, numbers, WhatsApp and providers, a reseller API for client accounts, and an MCP server hosted at mcp.omnidim.io/mcp (OAuth 2.1) or run locally through npm.
In practice
A real estate agency feeds new portal leads into a dynamic campaign through the webhook API, the agent calls within seconds in Hindi or English, scores interest, and a workflow alerts the broker on WhatsApp for hot leads.
A clinic puts its reception and reminder agents in one memory pool, so a patient who called about a refill is greeted with that context when they message on WhatsApp the next day.
A collections team runs a bulk campaign with retries, uses a custom API action to look up the balance and log a promise to pay, and sends a WhatsApp payment link template during the call.

Custom API turns any REST endpoint into an action the agent can take during a conversation, so it can look up an order, check a balance or write a booking, and a custom API transfer lets the business's own system return the number a live call should go to through one reserved response key. Prebuilt connectors and post call actions reach Salesforce, HubSpot, Slack, Google Sheets, Omni CRM and GoHighLevel, and Make, Zapier and self hosted n8n extend the reach to thousands of apps.

| Workflow Orchestration | Full |
|
OmniWorkflows is a visual canvas where each workflow has one trigger and a chain of nodes: AI nodes that read, decide, score or classify leads, flow control nodes that branch, wait and switch, CRM nodes that read and update records, and integration nodes, with data passed from earlier nodes to later ones. Workflows place voice AI calls, retry and schedule callbacks, and run up to 10,000 or 100,000 executions a month by plan, while each agent's own conversation is organized into instruction sections.

| Knowledge Grounding & RAG | Full |
|
Knowledge bases give an agent document based references for domain answers, with storage of 10MB on Starter, 50MB on Jump Starter, 100MB on Growth and custom limits on Enterprise, and they are attached in the agent's configuration so several agents can draw on the same material. A separate web search tool gives agents real time internet access when a question falls outside the stored documents. Sourcedocs.omnidim.io/docs/dashboard-guides/knowledge-baseread 2026-10-18 |

| Human Oversight & Guardrails | Partial |
|
Calls transfer to people, including to a number chosen by the business's own API, and live call monitoring shows in progress calls as transcripts and status for supervisors. On WhatsApp, the team can read every conversation, take a chat over from the agent and hand it back, and switch agent replies off for a number. Actions the agent takes through custom APIs run without a person approving them first. Sourcedocs.omnidim.io/docs/whatsapp/inboxread 2026-10-18 |

| Security, Identity & Governance | Partial |
|
Accounts add team members by plan, two to ten and unlimited on Enterprise, an organization admin sets view and edit access for caller memory, and resellers issue, rotate and revoke API keys for each client user. OmniDimension states that HIPAA, SOC 2 and PCI DSS certifications are not currently published and that deals needing written attestation go to sales, so the access controls stand without a compliance posture.

| Observability & Auditability | Full |
|
Recent calls hold chat and call logs for every conversation, live call monitoring streams in progress calls as transcripts, Growth adds recording insights, and WhatsApp insights show delivery, read and failure reasons per number. OmniWorkflows execution logs let teams find any run and inspect what every node received and produced, caller memory keeps a reviewable history of every change, and agent versioning records configuration changes.

| Memory & State Persistence | Full |
|
Caller memory lets agents remember each caller across phone calls, web calls and chat, and WhatsApp. Agents are grouped into memory pools that share what they know about a caller while other agents stay apart, and the memory holds six defined parts, updated on set events, with a stated list of what is never stored. Users with view access see exactly what agents are told about a caller, every change is reviewable, and users with edit access can forget a caller, which deletes the memory and all its versions for good.

| Deployment & Data Residency | Not documented |
|
OmniDimension runs as a hosted multi tenant service from a US company, with numbers in more than 70 countries, SIP trunking and imported Exotel numbers, and an OmniRelay white label edition on an agency's own domain. The privacy policy says call recordings and transcripts are stored on the customer's behalf without naming a region, and no region selection, private cloud or on premises option is offered.

| Prebuilt Agents / Templates / Packs | Partial |
|
Workflows can start from ready made templates, and a templates and patterns guide covers hot lead alerts, fast lead calling, retries, callbacks and business hours handling. Vertical and use case pages describe agents for real estate, healthcare, insurance, restaurants, finance, education, ecommerce, lead generation and collections, but agents themselves are configured from plain instructions rather than chosen from a gallery of finished agents.

| Triggers & Channel Coverage | Full |
|
One agent can be deployed on phone numbers in more than 70 countries, web calls and chat, WhatsApp messages and WhatsApp calls, email and SMS. Bulk call campaigns run outbound lists with retry logic, dynamic campaigns accept contacts in real time through a webhook API for CRM driven calling, WhatsApp broadcasts send approved templates, and workflow triggers start calls from outside events. Agents speak more than 90 languages, with strong coverage of Indian languages. Sourcedocs.omnidim.io/docs/bulk-calls/dynamicread 2026-10-18 |

| Model Flexibility & Routing | Full |
|
An agent's full configuration sets its transcriber, its language model and its voice, and the API's providers endpoints list the available LLM, voice, speech to text and text to speech providers, so builders choose the model behind each agent from code or the dashboard. More than 1,000 voices across 90+ languages are available, including cloned voices on every paid plan. Sourcedocs.omnidim.io/docs/api-referenceread 2026-10-18 |

| APIs / SDKs / MCP Extensibility | Full |
|
A REST API with a Python SDK and an interactive playground creates and configures agents, runs campaigns, buys numbers, sends WhatsApp messages and lists providers, authenticated with an API key, and a reseller API creates, funds and verifies client accounts. An MCP server, hosted at mcp.omnidim.io/mcp over streamable HTTP with OAuth 2.1 or run locally from npm with an API key, publishes a full tool catalogue for Claude, Cursor and Windsurf, and a WebSocket protocol drives web calls from iOS, Android and Flutter apps.

| Testing, Debugging & Optimization | Partial |
|
Workflows run with sample data before publishing, and a single AI node can be tested on its own. Agents can be tried on WhatsApp in minutes by linking a phone with a QR code, agent versioning keeps earlier configurations, and call logs feed improvements to the agent. There are no scored test cases, simulated callers or release gates that grade an agent's conversations. Sourcedocs.omnidim.io/docs/workflows/test-and-publishread 2026-10-18 |

| Browser / Computer-use | Not documented |
|
Agents act through custom API calls, connectors, workflows and messaging channels, and a web search tool fetches information from the internet when they need it. None of this has an agent open a browser or desktop session to click through another application's screens, and the web call widget is a channel customers use to talk to the agent rather than a browser the agent drives.

What is public
Every plan price, per minute rate, approximate minutes, team and knowledge limits, top up rates and agency plans.
Billing mechanics
Monthly plans or pay as you go top ups at falling per minute rates; INR billing in India.
Cost watchouts
Telephony numbers, WhatsApp template fees from Meta and email or SMS channels on Growth only may add cost.
Variable cost rationale
Plan fees convert into minutes at a fixed rate and extra minutes come from top ups, so cost tracks call volume with a lower rate at higher tiers and larger top ups.
Additional watchouts
Email and SMS channels start on Growth.
Overage / add-ons
Usage beyond a plan's minutes draws on top ups priced $0.063 to $0.054 a minute by size, with bonus minutes on larger top ups; above 25,000 minutes a month rates are quoted.
Sales call required
Mixed (some tiers require a call)
Free / trial
Free plan with about 20 minutes; OmniRelay agency plan has a 3 day trial
Lowest paid plan
Starter at $20 a month, about 317 minutes at $0.063 a minute
Commercial notes
Free entry plan and an introductory Jump Starter price.
Key ambiguities
Included minutes are approximate because each plan fee converts at its per minute rate.

No setup fees or platform charges; cancel anytime; customers on older plans keep their price until they change.
Support SLA / resale
Reseller and OmniRelay plans give agencies unlimited client workspaces, client funding at their own rates and white label branding.
