Install one workspace. Use the capability the task needs

You do not need to understand every Think-Act feature before installing it. Start with writing, a document, a recording, or a bounded agent task, then add reusable Skills and connectors only when they are useful.

Browse all features
Multi-step work

Desktop Agent workspace

Give Think-Act a clear task and keep the important decisions visible

Provide the source material and desired outcome, let the run use the capabilities available to it, respond where approval is required, and inspect the result before relying on it.

Bounded tasks

Keep the outcome and available capabilities specific to the job.

Approval controls

Supported actions can follow ALLOW, ASK, or BLOCK policy.

Review the Desktop Agent

Writing Assistant

Draft, rewrite, summarize, translate, clarify, or tighten text without moving the job into another tool.

Explore writing

OCR & documents

Extract text and useful information from supported screenshots, scans, images, PDFs, and forms.

Explore document tools

Screen Recorder

Record a process, walkthrough, or bug reproduction so the real sequence can be documented or reused.

Explore recording

MCP connectors

Add supported local or connected capabilities only when a real workflow needs access to them.

Review integrations

Security & control

Decide how supported actions should be handled

Use approval rules such as ALLOW, ASK, and BLOCK, keep enabled capabilities intentional, and review supported workflow activity.

Review security controls

Reuse & maintenance

Local Skills and app updates stay part of the workspace

Getting started

From download to your first workflow

The setup flow below applies to the Windows installer linked on this page. Think-Act also has a macOS version, and installation details can differ by platform.

Pre-install checklist

Windows installer

  • Use a machine you control

    Install Think-Act on a computer you own or are authorized to manage.

  • Have a PixLab account ready

    A PixLab account is required to activate Think-Act and connect the app to your plan and usage limits.

  • Use the official source

    Download from pixlab.io and verify PixLab or Symisc Systems if Windows presents publisher information.

  • Keep dependencies optional

    Node.js or Python is needed only when a specific local MCP server requires it.

  • Review permissions before connecting tools

    Configure approval rules before enabling external capabilities that can affect files or connected systems.

  1. Download

    Get the Windows installer from PixLab

    Use the current official Windows installer link on pixlab.io. Avoid re-hosted copies from unknown third parties.

    Download Windows Installer

  2. Verify & install

    Check the source before continuing

    On 64-bit Windows 10 or Windows 11, run the setup file. If Windows asks you to confirm a publisher, check for PixLab or Symisc Systems before continuing.

  3. Sign in

    Connect the app to your PixLab account

    Open Think-Act and sign in. Your account connects the desktop application to your plan and the usage limits available to you.

  4. First run

    Try something small and easy to review

    Rewrite a message, OCR a screenshot, inspect a document, record a process, or give the Desktop Agent a clearly bounded task with a result you can check.

    Rewrite text OCR a screenshot Review a document Record a process

  5. Extend later

    Add optional integrations only when they help

    Writing, OCR, document intelligence, and recording do not require MCP. Install Node.js or Python only when a specific local connector requires it.

Plan a Team Deployment
Team & enterprise deployment

Plan organization-wide installs separately from a normal desktop download

Managed deployment may involve installer rollout planning, administrative policy, approved connector lists, update policy, and least-privilege accounts. Windows environments may also involve MSI planning. Some organization-level controls remain roadmap items, so confirm current availability with PixLab before designing a rollout.

Plan a Team Rollout Review Security Controls

Topics to confirm before rollout

  • Installer and deployment method

    Confirm the currently supported installation approach for each desktop platform in your environment.

  • Approval and connector policy

    Decide which supported actions and external capabilities should be available to team workflows.

  • Update management

    Confirm how application updates should be reviewed and introduced in managed environments.

  • Current versus roadmap controls

    Verify which organization-level features are available today before depending on them in deployment policy.
