Why Think-Act exists

Stop rebuilding context every time the work moves

Desktop work rarely stays in one place. A report may lead to a screenshot, a selected paragraph, a quick rewrite, a recording, or another application. Think-Act is built to reduce the friction between those steps without forcing every task into a complex workflow.

Work from the source you already have

Keep documents, screenshots, recordings, selected text, and local files close to the task instead of repeatedly explaining the same context elsewhere.

Keep simple tasks simple

Use writing, OCR, document intelligence, or recording on their own. Bring in the Desktop Agent only when several steps genuinely need coordination.

When the task is fragmented

One task turns into a chain of handoffs

Open the source

PDF, screenshot, local file, selected text, or recording

Copy or describe the context

Rebuild enough detail for another tool to understand it

Move the result again

Repeat the handoff when the task needs another capability

With Think-Act

Keep the useful parts of the task together

Start from the relevant source, choose the capability that fits the current step, and keep the result close enough to inspect before continuing.

Inside Think-Act

Pick the capability that fits the job. Connect the work when it grows

Writing, document intelligence, and recording remain useful on their own. The Desktop Agent adds coordination when one outcome spans context, several capabilities, connected tools, or approval steps.

Multi-step work

Desktop Agent

Give Think-Act a clear outcome, not unlimited control

Give Think-Act the source material, the outcome you want, and the capabilities available to the run. Follow supported activity, respond where approval is required, and review the result before relying on it.

  • Optional success criteria can define a clearer finish line
  • Supported execution activity can remain available for review
  • Consequential actions can follow ALLOW, ASK, or BLOCK policy
  • A reviewed method can later become a reusable local Skill
Review How the Desktop Agent Runs Tasks

Write, rewrite, translate or summarize

Rewrite, summarize, clarify, translate, or draft from selected or supplied text, then review the result before using it.

See Writing Assistance in Action

Extract and review document content

Extract text and useful document information from supported scans, screenshots, images, and PDFs, then organize or carry it into the next step.

Review OCR & Document Intelligence

Record a process and prepare documentation

Capture a walkthrough, procedure, or bug reproduction so the real sequence remains available for documentation or later analysis.

Focused desktop tools

Some work only needs one
good desktop tool

Open writing, document intelligence, or recording directly when the job is focused. If the work expands later, the useful output can become context for a broader Think-Act task.

OCR & Document Intelligence

See OCR in Detail

Writing Assistant

Rewrite, summarize, translate, and draft selected text with the help of AI.

See Writing Assistant

Screen Recorder

Capture a process, walkthrough, or bug reproduction so the context can be reviewed and reused.

Context from your desktop

Start with the source, not a blank prompt

Bring in the material the task actually depends on. Think-Act can work from selected text, documents, local files, screenshots, scanned material, recordings, and transcripts so the next step starts with concrete context.

Keep the working set intentional

Attach the files, passages, screenshots, or recordings that belong to the task instead of treating the whole desktop as context.

Turn visual material into usable information

Use OCR and document intelligence to extract text and useful structure from supported scans, screenshots, images, and PDFs.

Carry useful output into the next step

A transcript, extracted field, summary, or rewritten passage can become the input for the next step without another manual handoff.

Files & PDFs

Screenshots

Selected text

Recordings

Think-Act can begin with relevant selected text, local files, PDFs, screenshots, scans, recordings, and transcripts.
A reviewable agent run

Follow the task from source to checked result

A useful Desktop Agent run should make the important parts understandable: what it started from, which capabilities were used, where approval was required, and what still needs checking.

Think-Act can keep supported task activity, tool use, approvals, observations, and results available for review.
  1. Define

    Give the run a specific outcome

    Describe what should be achieved and, when useful, define criteria that make the finish line easier to recognize.

    Better: โ€œExtract the invoice details, identify anything inconsistent, and prepare a reviewable reply.โ€

  2. Context

    Add only what the task depends on

    Bring in relevant documents, screenshots, files, selected text, recordings, transcripts, or extracted information rather than treating the entire desktop as task context.

    Files PDFs Screenshots Selected text Recordings
  3. Capabilities

    Keep available tools intentional

    The run can use supported Think-Act capabilities and connected tools that are available to it. A connector that is disabled, unavailable, or unhealthy stays outside the task.

  4. Approval

    Pause where policy requires your decision

    Supported consequential actions can proceed automatically, ask for confirmation, or remain blocked according to the configured policy.

    ALLOW ASK BLOCK
  5. Verify

    Check the result against the original task

    Inspect the result together with relevant supported activity and compare important values, claims, or conclusions with the original material before relying on them.

Extend a workflow deliberately

Skills preserve the method. Connectors extend the reach

Skills and connectors solve different parts of the problem. A Skill preserves a useful way of working. A connector gives the task access to another supported capability when the workflow actually needs it.

Reusable method

Think-Act Skills

Keep a good way of working

Turn reviewed instructions, checks, and conventions into a reusable local Skill so the next similar task does not have to start from scratch.

Useful when

You already have a method that works and want future tasks to follow it consistently.

  • Preserve task instructions and conventions
  • Keep useful review checks
  • Repeat a proven workflow pattern
Tool access

MCP & connectors

Give the task another capability

Connect a supported local or external tool when the workflow needs access beyond Think-Act's core desktop capabilities.

Useful when

The task needs to interact with another supported capability instead of only working with supplied context.

  • Add supported external capabilities
  • Keep tool access scoped to the workflow
  • Apply approval policy to supported actions

Available capabilities and approval policy determine what a supported run can do. Processing location still depends on the model, endpoint, connector, and workflow you configure.

Think-Act can expose tool availability, action policy, approval requirements, and supported task activity for review.
Security & control

Decide what can happen before the task starts

A desktop agent may work with files, applications, and connected systems. Think-Act keeps access and approval policy visible so important actions remain deliberate and reviewable.

Scoped capabilities

Unavailable or disabled connectors stay outside the run.

Action policies

Supported actions can allow, ask, or remain blocked.

Reviewable activity

Inspect supported observations, approvals, tool calls, and results.

Data flow awareness

Processing location depends on the configured model, endpoint, connector, and workflow.

Common questions

What to know before you install

The essentials about desktop support, connectors, approvals, processing, and how Think-Act differs from a browser-only AI workflow.

What exactly is Think-Act?

Think-Act is a desktop AI workspace for Windows and macOS. It brings together writing assistance, OCR and document intelligence, screen recording, reusable Skills, integrations, and a controlled Desktop Agent guide for work that needs several coordinated steps.

Which desktop platforms are supported?

Think-Act is available for Windows and macOS. Visit Windows and macOS downloads for the current installers and platform requirements.

Do I need MCP connectors to use Think-Act?

No. Writing assistance, OCR/document intelligence, and screen recording can be used without MCP. A connector matters when a task needs access to another supported capability. See Skills and connector guide for the distinction between reusable instructions and tool access.

Can the Desktop Agent take actions without asking me?

That depends on the capability and the policy configured for the run. Supported actions can be set to ALLOW, ASK, or BLOCK. A capability that is unavailable or disabled cannot be used by the task. Review security and approval model before enabling higher-impact actions.

Does Think-Act run everything locally?

Not necessarily. Think-Act runs as a desktop application, but the processing location depends on the model, endpoint, connector, and workflow you configure. Check the data-flow guidance before using sensitive material.

How is Think-Act different from browser-only AI?

Browser AI often begins by asking you to move or describe the context first. Think-Act is designed around desktop work, so a task can begin from the text, document, screenshot, recording, or file already involved in the job and bring in additional capabilities only when they are useful.
