An AI agent builder that answers calls, texts and web chats without code

What is Mei?
Mei is an AI product lab running an AI Agent Builder, a no-code tool for creating assistants that handle phone calls, SMS and website chat. It also operates consumer apps for messaging, voice agents and translation, with enterprise and telecom deployment options.
Mei is the umbrella brand for an AI product lab that has been building messaging and communication software since 2016. Its core product is the AI Agent Builder, a self-service tool for assembling a custom assistant without writing code. The agent is defined by a role and a set of instructions, the equivalent of a job description that spells out what it handles, what it should know, and when a human needs to be pulled in. From there, the agent is attached to a communication channel and starts picking up conversations. The builder is the centerpiece, but Mei ships a wider catalogue of consumer tools alongside it. The AI Directory lists coaches, companions and translators that run on the web and often over phone calls or SMS as well. Voxie puts AI personalities on ordinary phone numbers. The Android messaging app adds an optional assistant for drafting replies and reading conversation context. A voice recorder turns Android audio into transcripts, and a separate image tool handles text extraction and photo restoration. Businesses can ask Mei to adapt any of this into a branded service or an internal workflow. The practical appeal is familiarity. Rather than forcing users into a new interface, the agents work through channels people already open every day: SMS, voice calls, email, website widgets and messaging apps. The same agent keeps context for recognized contacts across sessions and across channels, so a caller who follows up by text does not have to repeat the conversation. Access is governed by identity and permissions, which lets one agent act outwardly as a representative while also serving the owner privately. Mei fits best for solo operators, small businesses and telecom partners that need a functioning conversational agent quickly and cheaply, rather than for teams wanting deep model control or a sprawling integration library. Signing up is free, while phone numbers, usage and additional services are billed separately. Buyers comparing dedicated chatbot platforms should note that Mei's strength is breadth of channels and product range, not the quantity of published third party connectors.
How do you use Mei?
1Review the platform before you build
Read the AI Agent Builder page to see how roles, knowledge and channels fit together. It explains the three step model of assigning a role, preserving context and setting identity based permissions.
2Sign up for the builder
Open the builder through the Messages Improved brand it operates under. Creating an account is free, and phone numbers or usage are charged separately once a live channel goes into service.3Create the agent and give it a role
Name the agent, write an opening message, pick a language and supply instructions. Treat the instructions as a job description covering what to handle, what to know and when to escalate to a person.4Add knowledge and connect a channel
Attach the reference material the agent should draw on, then link a supported channel such as phone calls, SMS or website chat. Test the conversation before pointing real traffic at it.5Explore ready made agents and other products
Browse the AI Directory to chat with public coaches, companions and translators, many of which also work over phone and SMS. This is a fast way to judge what a well configured agent feels like.
6Plan an enterprise or developer path
If the project outgrows self-service, talk to the team about custom development, white label deployments or the APIs. Telecom operators and businesses can license the underlying technology.
Pros and cons
Pros
- No-code agent creation that starts from a role description, greeting and language rather than a technical setupAI
- Agents run on everyday channels such as phone calls, texts, email and website chat, so end users need no new appAI
- Recognized contacts are remembered across sessions and connected channels, which keeps follow-up conversations coherentAI
- Broad portfolio behind the builder, including translators, voice agents and an Android messaging appAI
- Sign up is free and the builder is self-service, so a single person can test an assistant concept without a teamAI
Cons
- Pricing for phone numbers, usage and add-on services is not published up front, so total running cost is hard to forecastAI
- No named third party integrations are listed, which matters if the agent must plug into an existing CRM or helpdeskAI
- Consumer agents, the Android app and the builder live under different brands and URLs, which makes the product family harder to navigateAI
- Enterprise features, white label options and custom development require contacting sales rather than self-service signupAI
- Documentation depth and reliability at scale are difficult to judge from the marketing pages aloneAI
