Algomo vs Sierra
Intrepid Travel's website chat runs on Sierra, an enterprise rollout. On the same website, an AI agent built Algomo's assistant from the outside, and we asked both the same questions.
Algomo is an AI agent for your website that integrates itself, works the page alongside your visitor, and is run from your own coding agent, on a free plan with public prices. Sierra needs a sales call and an agent development team, and publishes no pricing.
The answers, side by side
Recorded on Intrepid's UK website on 6 October 2026. Each answer is quoted from the recording, beside what Intrepid's own site says and marked against it. Intrepid Travel is not an Algomo customer, and Sierra's answers may be different today.
Can I hold a trip without paying a deposit?
intrepidtravel.com says
“Save your spot on a trip for up to 5 days without paying a deposit”, on the flexible bookings page.
Sierra
SierraContradicts the page
Further down, the same answer says a trip on hold needs its deposit paid within 5 days. Its opening word is still “no”.

The five trips are listed before the ryokan condition is applied; it offers to narrow them down instead.

What it took on intrepidtravel.com
Intrepid is the kind of company Sierra is built for, and its chat is the kind of rollout Sierra sells: a contract, a team, weeks of work. On the same site, an AI agent built a better experience from the outside, with no access to Intrepid's systems.
Sierra, Intrepid's chat
- An enterprise contract, bought through Sierra's sales team. Sierra publishes no prices.
- Built with Sierra's agent development team, which deploys in weeks, in Sierra's own words.
- Answers inside its own chat window, in text.
Algomo, from the outside
- No contract and no integration project: Intrepid is not an Algomo customer.
- Built by an AI agent: it read Intrepid's public website and found the search and pages the site already uses.
- Answers in its chat, and opens Intrepid's own pages, search results and route maps beside it.
Why Algomo?
Run it from your own agent, not their harness
Sierra's answer to agent-building is Ghostwriter, an internal chat that builds agents inside Agent OS, answering with its own constellation of models. Algomo is no builder at all: it is an MCP server, and you build and operate it from Claude Code, Codex or ChatGPT, on the frontier labs' models.
The labs will out-invest every internal harness in this category, and your own agent already knows your company. Ghostwriter only ever knows what was typed into Ghostwriter.
The agent deploys itself
Sierra staffs each rollout with an agent development team and deploys in weeks. The integration work that team does is the work Algomo's agent does itself, from the endpoints your site already calls. Our deployment engineers are optional help, not the product.
It runs as the visitor
Sierra's agent acts server-side. Algomo also acts in the visitor's own session: it co-navigates your site with them, and its calls run in their browser with their prices, their region and their login.

Every Sierra cell was read from sierra.ai on 31 August 2026, and the pricing page rechecked on 6 October 2026. Algomo's cells are read from this site's pricing page.

| What $50 a month buysA conversation the agent helped with costs five credits and one that went nowhere costs nothing. Tool runs cost one credit and knowledge-base reads half a credit each, so real conversations use a little more. | 2,000 credits: up to 400 helped conversations | Not published |

Page last updated 6 October 2026. Where these rows come from: Ghostwriter is their own name, the agent-building agent, on its product page; the model constellation and deploy in weeks are on the product pages; the channel list, including ChatGPT over MCP, is on the channels page; the Fortune-50 figure is Sierra's homepage claim; the staffed model shows on the careers page, which lists an agent-development org of roughly forty open roles. Outcome-based with no numbers is their own description, and their pricing page is a 404.
Which one to choose
Choose Sierra if
- You run a Fortune-500 support operation. Sierra runs voice for some of the largest in the world.
- You want phone, SMS, WhatsApp, email and ChatGPT from one vendor, as well as web chat.
- You want a staffed agent-development team on the contract to build and run the agent for you.
- A rollout measured in weeks, bought through a sales process, fits how you buy.
Choose Algomo if
- The agent's job is your website: answering visitors, and qualifying the ones who came to buy. Algomo answers in web chat only.
- You want to try it on your own site today, on a free plan, before any sales call.
- You would rather build and run it from your own coding agent than through a vendor's team.
Test Algomo against Sierra on your own site
The recording above is our test on Intrepid's site. This is the same test on yours, and the first three steps cost nothing.
- 01
Pick the questions
Five questions your customers really ask: one about a policy on your own pages, one with three conditions in it, one about a single product, and one that ends in a price.
- 02
Put Algomo on your site
Start free and connect Algomo to your coding agent. It learns your site from its URL and the endpoints your pages already call.
- 03
Ask both the same things
Ask Algomo and the chat you are comparing it with the same five questions, in the same order, in a new session each.
- 04
Check every answer against your site
Put each answer beside what your own page says, the way the answers above are. An answer is only as good as where it was read from.
Questions, answered
How much does Sierra cost?
Sierra does not publish its prices. Its pricing is outcome-based, sierra.ai/pricing returns a 404, and a quote comes through its sales team. Algomo's prices are public: a free plan, then $50 to $4,300 a month on Business, and the support ROI calculator works out what it would cost and save at your volume.
Is Algomo just a cheaper Sierra?
It is a different mechanism. The integration work Sierra staffs with engineers is the work the agent does itself here, from the endpoints your site already calls, and you direct it from your own coding agent rather than through a vendor team.
Can I try Algomo before talking to sales?
Yes. The free plan is self-serve, and you can try Algomo live on Intrepid's site right now without signing up.
Does Algomo do voice, SMS or WhatsApp like Sierra?
No. Algomo answers in web chat on your site. If you need one vendor for phone, SMS and WhatsApp as well, Sierra is the closer fit.
Can it handle things behind a login?
Two ways: calls that should run as the visitor run in their session with their cookies, and internal systems are set up with us on Business and Enterprise.
What if our site changes?
A connector that starts failing raises a task, and your coding agent repairs it over MCP: rediscover the endpoint, restage, test on the live site, save.
Other Sierra alternatives, compared
vs Intercom Fin
Both count the same event, a conversation that actually helped, so this is the cleanest comparison in the category. The difference is the ceiling: Fin bills every outcome with no limit, Algomo is a monthly amount you pick.
vs Intercomvs Decagon
They solve deployment with deployment engineers. We made deployment the part the agent does itself.
vs Decagonvs Ada
Enterprise service across voice, messaging and email, sales-gated, with a developer toolkit that lists MCP.
vs Adavs delight.ai
Sendbird's concierge, sold by demo, whose pricing URL redirects to an essay about pricing.
