Simular

What it does

Sai takes a plain-language task description and runs it on a computer, clicking and typing through browsers, desktop apps, file systems and terminals. It works from screen views rather than relying only on APIs, so it can handle software that exposes no automation interface. Outputs are the results of the completed work, such as updated files, spreadsheets, drafts or reports, with live visibility into each step.

People use Sai for repetitive multi-app work such as research, lead sourcing, follow-up drafting, scheduling, spreadsheet updates and recurring reports. Teaching a task once lets it rerun on a schedule, and the vendor says repeated runs become more reliable and cheaper. Sai can run on a cloud virtual machine so tasks continue after a laptop is closed, with notifications and approvals through iMessage or Telegram.

Sai suits multitaskers and business teams with high volumes of screen-based routine work and does not require technical skills or APIs. Access is through the sai.work site and sign-in, with a free cloud account and a separate Simular API for developers. Limitations include approval requirements for important actions, a first request that can take about two minutes to start on a free account, and consumer pricing that should be verified on the vendor pricing page.

• Important actions may need approval, and the agent continues only as far as approvals allow.

Get started

Sign in to Sai to start; developers can create an API key in the Simular platform portal.

1. Sign in to Sai at sai.simular.ai, or follow the Simular API quickstart to sign in with Google.
2. For the API, create an API key in the portal and export it as SAI_API_KEY; free accounts must complete phone verification first.
3. Send a first plain-language task through the API message endpoint and poll the events endpoint, allowing about two minutes for a free account's first computer to start.

A free API account is titled Free, holds one key and shows a small credit balance in the quickstart example ($0.35); paid accounts hold up to 20 keys. Business use is through Contact Sales. Verify current Sai and API rates on the pricing pages before committing.
