Files & documents

Describe a document, presentation, image, or visualization and Sim creates it — streaming the content live into the resource panel as it writes. Attach any file to your message and Sim reads it, processes it, and saves it to your workspace.

Uploading Files to the Workspace

Attach any file directly to your message in Chat — drag it into the input, paste it, or click the attachment icon. Sim reads the file as context and saves it to your workspace.

Use this to:

• Hand Sim a document and ask it to process, summarize, or extract data from it
• Upload a CSV and have it create a table from it
• Drop in a PDF and ask Sim to turn it into a knowledge base document
• Attach a design mockup and ask Sim to describe it or generate code from it

Uploaded files appear in the Files panel in the sidebar and are accessible to all workflows in the workspace. Sim can also fetch a file directly from a URL and save it for you: "Download the JSON at [URL] and save it to the workspace."

Creating Documents

Sim can write any text-based file — markdown, plain text, code files, CSV, JSON, or any other format:

• "Write a technical spec for the new auth system as a markdown file"
• "Create a CSV of our test accounts with columns for name, email, and plan tier"
• "Write a Python script that calls our workflow API and processes the response"
• "Draft a postmortem for the outage last Tuesday and save it as a markdown file"
• "Write a personalized outbound email for Acme Corp based on their recent funding announcement"
• "Draft a weekly ops digest summarizing workflow run counts, errors, and top failures for the past 7 days"

Files are saved to your workspace and accessible from the Files panel in the sidebar.

Editing Existing Files

Open a file using @filename or the + menu, then describe the change:

• "Update the pricing section to reflect the new tiers"
• "Refactor this Python script to use async/await"
• "Add a section on error handling to this spec"
• "Rewrite the introduction of this report to be more concise"

Presentations

Sim can generate .pptx files:

• "Create a pitch deck for Q3 review — 8 slides covering growth, retention, and roadmap"
• "Turn this research report into a 10-slide presentation"
• "Build a deck that walks through our API onboarding flow"
• "Build a battle card deck for our top 3 competitors — one slide each covering positioning, pricing, and how we win"
• "Create an account plan for Acme Corp — their priorities, our solution fit, and proposed next steps"

The file is saved to your workspace and can be downloaded.

Images

Sim can generate images using AI, and can use an existing image as a reference to guide the output:

Generating images:

• "Generate a banner image for the new feature announcement — dark background, clean typography"
• "Create a diagram showing the data flow through our webhook pipeline"
• "Make a social card for the blog post with the title and author name"

Using a reference image:

• Attach an existing image to your message, then describe what you want: "Generate a new version of this banner with a blue color scheme instead of green"
• "Create a variation of this diagram with the boxes rearranged horizontally [attach image]"

Generated images are saved as workspace files.

Charts and Visualizations

Sim can generate charts and data visualizations from data you describe or reference:

• "Plot the workflow run counts from the metrics table as a bar chart grouped by week"
• "Create a line chart of token usage over the past 30 days from this data [paste data]"
• "Generate a pie chart showing the distribution of lead sources from the leads table"

Visualizations are saved as files and rendered in the resource panel.

Calculations & Data Processing

For one-off calculations and data transformations, describe what you need and Sim runs it directly in the chat:

• "Parse this JSON and extract all records where status is 'failed'"
• "Calculate the p95 latency from these timing values: [paste values]"
• "Convert these Unix timestamps to ISO 8601"
• "Deduplicate this list of emails, case-insensitive"

Results come back directly in the chat. Ask Sim to save the output as a file if you need it.

File Viewer Modes

When a file opens in the resource panel, you can switch between three views:
