What Is Twin?
Twin is a no-code AI agent builder. Users describe an automation goal in plain language and Twin plans the steps, connects to the relevant tools, and executes the work, using APIs where available and an embedded browser when a website has no API. Agents can run once or continue running on a schedule or trigger. The product is made by Twin Labs, founded in 2024, and operates at twin.so and builder.twin.so.
Who It Is For
| User Type | Notes |
|---|---|
| Non-technical users | Official documentation states Twin lets non-technical users turn simple prompts into production-ready agents with no code required |
| SMBs and agencies | Twin Labs’ official GitHub page names delivery services, rental operators, real estate agents, agencies, and e-commerce stores as its fastest-growing user segment |
| Teams moving off Zapier, Make, or n8n | The official homepage positions Twin as a replacement for these tools via natural-language agent building |
| Creators and consultants building agents for clients | The affiliate programme page describes building agents for clients and distributing or managing multiple accounts |
Key Features
- Conversational agent building: Agents are created by describing a goal in plain language; Twin plans the steps and builds the automation logic without code.
- Browser automation fallback: When a tool has no API or the right scopes, Twin logs in, navigates the interface, and extracts data or completes actions directly in an embedded browser.
- Scheduling and triggers: Agents can be deployed once and run repeatedly on cron-style schedules, webhooks, emails, or messages.
- Persistent agent state: Each agent has its own database, file handling, and document or spreadsheet output, with an optional shareable web app.
- Multi-model routing: Twin routes tasks across models from OpenAI, Anthropic, and open-source providers, selecting a model per step.
- Build mode and run mode: Creating or updating an agent uses higher-reasoning, more credit-intensive processing; repeat runs of a deployed agent use a lighter-weight mode that is typically 3 to 10 times cheaper.
- Agent deployment and monetisation: Documented as a Pro plan inclusion, alongside web search, deep research, image and video generation, and slide deck generation.
- Custom agent interfaces: Documentation describes a “Build Interfaces” capability for creating full apps on top of an agent.
- REST API access: Agents can be triggered from a user’s own backend via the Twin REST API.
Pros and Cons
Strengths:
- No-code, natural-language agent creation with no engineering step required.
- Browser automation extends coverage to websites and tools that have no API.
- A free trial is available with no credit card required.
- Credits are only deducted for real agent work, not for idle or saved agents, per official pricing documentation.
Criticisms:
- One reviewer on Trustpilot described a session where the interface stopped responding while a task kept repeating, consuming a large number of credits with no way to pause it.
- The same reviewer reported that support was unable to resolve the issue beyond explaining the credit usage.
- The same reviewer stated that free tier trial credits did not apply in their case.
- Current verified positive review themes are not clearly available from reputable sources, since the visible Trustpilot content for twin.so at the time of research consisted mainly of this critical account.
Pricing
Twin uses a credit-based system. Credits are consumed for building agents (higher reasoning, more credit-intensive) and for running deployed agents (lighter-weight, typically cheaper). Prices below are from the official pricing documentation and use the same list price in USD and EUR.

Reviews
A Twin (twin.so) profile exists on Trustpilot with a small number of reviews at the time of research. A separate Twin profile also appears on G2, but it describes a customer-support chatbot product rather than the twin.so agent builder, so it has not been used as a source for this page.
Positive Themes
Current verified user review data is not clearly available from reputable sources for positive themes specific to twin.so.
Criticisms
- A Trustpilot reviewer described a task that repeated itself after the interface stopped responding, consuming a large number of credits before support could help.
- The same review stated that support acknowledged the credit spend without resolving the underlying issue.
- The same review reported that expected free-tier trial credits were not received.
