DecagonCapability by capability: SPIRITT vs Decagon in detail
Decagon is a specialist built for enterprise support orgs. SPIRITT is an autonomous workspace that handles support and the rest of the company. Here is how that plays out.
| Feature | SPIRITT | Decagon | What this means for you |
|---|---|---|---|
| What it is | An autonomous AI workspace with its own cloud computer, memory, and tools that plans, builds, deploys, and operates real work around the clock. | An enterprise conversational AI platform for customer experience agents across chat, email, voice, and SMS. | Decagon is a CX product. SPIRITT is an operator that can run CX and much more. |
| Computer use | Computer use on your local computer (SPIRITT Desktop and your own Chrome) and on cloud computers, with many agents working on the same computer or spread across many computers. | Browser actions for systems without an API. No general computer use on local or cloud computers. | SPIRITT agents can operate full computers, locally or in the cloud. |
| Getting started | Self-serve sign-up. Test the real product on your own work, no sales call required. | Demo required. As of October 2026 there is no self-serve sign-up or trial. | With SPIRITT you can have a working support agent before a Decagon demo is even booked. |
| Speed to value | Describe the support agent or phone line you need and SPIRITT builds, connects, and runs it the same day, then keeps improving it. | Value starts after a demo, a contract, and a managed rollout with Decagon's team. | SPIRITT fits teams of any size and gets real work running first. Decagon is built around large enterprise sales cycles. |
| Models | Model fusion across Claude, OpenAI, Gemini, Grok, DeepSeek, Qwen, and more, plus SPIRITT's own Kay agents, routed per step. | Over 80% of traffic runs on models Decagon trained itself, mostly fine-tuned open-weight models. Customers do not choose the model. | Decagon picks the models for you. SPIRITT gives you the best model mix, including fast low-latency voice models, without lock-in. |
| Voice and phone | Buy a phone number, answer inbound calls, book appointments, escalate to a human, and run outbound call fleets from one request. | Voice 3 with Chord, an in-house speech model tuned for customer calls (October 2026), inbound and outbound via contact center platforms. | Decagon's voice is purpose-built for big call centers. SPIRITT gets you a working AI phone line on your own. |
| Quality and testing | Agents self-improve, and sensitive actions wait for your approval. | A mature stack: simulations at scale, live A/B experiments, Watchtower always-on QA, versioning, and root cause analysis. | Decagon leads on dedicated CX evaluation tooling. If that is your top need at enterprise scale, it is a real advantage. |
| Integrations | Thousands of ready-made integrations, and if one is missing, SPIRITT builds it end to end. Every connection and scope visible in one place. | Pre-built connectors for Salesforce, Zendesk, Intercom, Kustomer, and more, plus APIs, MCP, and Browser Actions. Docs are access-code gated. | Both connect to your support stack. SPIRITT reaches far past it. |
| Governance | Action-level rules for Read, Write, and Destructive operations, org-wide authorization, and time-limited single-use approvals. | Guardrails and versioning on agent logic. G2 reviewers cite granular user roles and audit logs as missing features. | SPIRITT puts fine-grained control over every action in your hands. |
| Beyond support | Builds and hosts full-stack apps, runs Deep Research, generates video, images, and audio, and runs sales, marketing, and ops work. | Agent Modules extend into lead qualification, onboarding, payment collection, and product discovery, all customer journeys. | Decagon stays inside the customer conversation. SPIRITT covers the whole company. |
| Bottom line | Self-serve support agents and a phone line today, enterprise deployment teams when you scale, and one workspace for everything else your business runs on. | A proven choice for large enterprises that want a fully managed CX rollout after a sales cycle. | Pick Decagon for dedicated CX QA tooling. Pick SPIRITT for a transparent product, hands-on enterprise help, and automation beyond support. |
| Enterprise delivery | SPIRITT deployment teams and forward-deployed engineers for enterprise rollouts, on top of a product your team can open, test, and change itself from day one. | A sales-led rollout with Decagon's team after a demo. Docs are access-code gated and there is no self-serve trial. | Same hands-on enterprise help. The difference is that with SPIRITT nothing is a black box. |
| Deployment options | Secure cloud by default. For enterprise: bring-your-own-cloud, dedicated deployments, and fully air-gapped options, with localization and local deployment teams. | Vendor-hosted SaaS. No published bring-your-own-cloud or air-gapped option as of October 2026. | Enterprise-grade deployment where it matters, and a product anyone can test first. |

Why SPIRITT is better than Decagon for support and beyond
Try it yourself, not a demo
Decagon is demo-gated with no self-serve sign-up or trial as of October 2026. SPIRITT is self-serve: sign up and test the real product on your own support work. For enterprise, SPIRITT deployment teams and forward-deployed engineers help you roll it out.
Your own AI phone line
SPIRITT buys a phone number, answers inbound calls, books appointments, and escalates to a human. You can also run outbound call fleets from a single request, with no contact center project required.
No model lock-in
Decagon runs most traffic on its own fine-tuned models and you do not pick. SPIRITT fuses frontier models from many labs with its own Kay agents, and lets you plug in ChatGPT, Claude, and Grok subscriptions you already use.
Support is just the start
The same SPIRITT workspace that answers customers can build and host apps, run Deep Research, create video and audio, and work across sales, marketing, and ops. SPIRITT is built with SPIRITT and runs much of its own company inside it.

Questions
Frequently asked questions
01What is the difference between SPIRITT and Decagon?+
Decagon is an enterprise platform focused on AI customer experience agents across chat, email, voice, and SMS, sold through demos and sales-led contracts. SPIRITT is a self-serve autonomous AI workspace that can run support agents and an AI phone line, and also builds apps, does research, creates media, and operates work across the company.
02Is SPIRITT a good Decagon alternative?+
Yes, especially if you want to start without a sales cycle or need more than customer support. SPIRITT lets you launch support agents and an AI phone line yourself, with no sales call, and the same workspace handles sales, marketing, and operations. If you are a large enterprise whose top priority is dedicated CX simulation and QA tooling at very high volume, Decagon is built for that.
03How fast can I get a support agent running with SPIRITT vs Decagon?+
As of October 2026 Decagon requires a demo, with no self-serve sign-up or trial, and rollouts run through its team. SPIRITT is self-serve: describe the support agent or AI phone line you need and SPIRITT builds it, connects your tools, and puts it to work on real conversations, with deployment teams and forward-deployed engineers available for enterprise rollouts.
04Can SPIRITT answer customer phone calls like Decagon?+
Yes. SPIRITT can buy a phone number, answer inbound calls, book appointments, and escalate to a human, and it can make outbound calls or coordinate a fleet of calls from one request. Decagon offers strong voice agents too, recently upgraded with its in-house Chord speech model, but they come through an enterprise contract.
05Where is Decagon stronger than SPIRITT?+
Decagon has a mature CX evaluation stack with large-scale simulations, live A/B experiments, always-on QA, and root cause analytics, plus a long list of enterprise CX customers. For big support orgs that want a fully managed rollout, that depth is a genuine advantage.
06Which AI models do SPIRITT and Decagon use?+
Decagon says over 80% of its model traffic runs on models it trained itself, mostly fine-tuned open-weight models, and customers do not choose the model. SPIRITT uses model fusion across Claude, OpenAI, Gemini, Grok, and more, plus its own Kay agents, routed per step, and you can connect ChatGPT, Claude, and Grok subscriptions you already have.
07Can SPIRITT do more than customer support?+
Yes. SPIRITT builds production-grade full-stack apps and hosts them on real URLs, runs Deep Research across the web and your systems, generates video, images, and audio, and works across sales, marketing, and operations. Decagon's expansion stays inside customer journeys like onboarding, lead qualification, and payment collection.
08Does SPIRITT offer forward-deployed engineers for enterprise?+
Yes. Enterprise customers get SPIRITT deployment teams and forward-deployed engineers who help plan, integrate, and roll out across the organization. The difference is that SPIRITT is not a black box behind a demo: your team can open the same product, test it on real work before signing, and keep seeing and changing everything after the rollout.
09Can SPIRITT run in our own cloud or air-gapped?+
Yes. Beyond SPIRITT's secure cloud, enterprise deployments can run in your own cloud (BYOC) or in fully air-gapped environments, with localization for your markets and local deployment teams to roll it out. Anyone can still sign up in the cloud and test the real product first.
