# Camera and screen guides for AI-assisted work

Show your assistant what changed after a practice step, test, edit, or troubleshooting check. LetItSee connects a camera or desktop share you choose to an image-capable MCP assistant. Each request returns one current still image.

## Choose your task

### Tutoring and learning

- [Learn from handwritten math](<https://letitsee.com/guides/handwritten-math-tutoring>) — Work through a math problem one handwritten step at a time, checking each still before getting a single next hint.
- [Learn CAD sketch constraints](<https://letitsee.com/guides/visual-software-tutoring>) — Predict what a horizontal constraint changes in a sketch, test it yourself, and verify the remaining degrees of freedom in CAD.
- [Repair a dropped knitting stitch](<https://letitsee.com/guides/dropped-stitch-knitting>) — Secure one loose loop and rebuild a few rows of a clear interior stockinette column, checking both faces before continuing.
- [Diagnose crochet curling](<https://letitsee.com/guides/crochet-curling>) — Separate a tight foundation edge, stitch-count drift, and intended round shape before changing the hook or blocking.

### Camera access in conversations

- [Add visual context when voice has no camera view](<https://letitsee.com/guides/chatgpt-live-camera>) — Check ChatGPT Live's camera limits and share requested snapshots with an assistant that supports image tools.

### Build, test, and troubleshoot

- [Troubleshoot a second computer](<https://letitsee.com/guides/second-computer-troubleshooting>) — Use phone photos of a disconnected computer as evidence in a deliberate symptom-to-next-check loop.
- [Review hardware test results](<https://letitsee.com/guides/hardware-test-results>) — Compare finished physical test output with a stated baseline, then choose a focused retest or measurement.
- [Inspect electronics at the bench](<https://letitsee.com/guides/electronics-bench>) — Pair close-up bench images with written readings and notes to track a deliberate inspection.
- [Keep a 3D print calibration log](<https://letitsee.com/guides/3d-print-calibration>) — Copy a test record that preserves the baseline, changed setting, observed result, and next decision.
- [Review a clipped interface label](<https://letitsee.com/guides/visual-ui-review>) — Compare the same interface state at a fixed viewport, then verify layout cause and interaction in browser tools.
- [Review 3D silhouette readability](<https://letitsee.com/guides/3d-modeling-feedback>) — Judge a model against a view-specific silhouette brief, then decide whether the issue belongs to form or composition.
- [Get no-code app help](<https://letitsee.com/guides/no-code-app-help>) — Use editor and preview screenshots to guide a human through a no-code app investigation and retest.
- [Troubleshoot first-layer gaps and adhesion](<https://letitsee.com/guides/3d-print-first-layer>) — Use the shape and location of first-layer lines to choose a model-specific calibration or adhesion check.
- [Troubleshoot PETG stringing](<https://letitsee.com/guides/petg-stringing>) — Choose a PETG stringing check from the recent profile, nozzle, and spool evidence, then compare one controlled test.

## Set up your source

These guides cover browser permissions, account matching, source selection, and troubleshooting.

- [Phone camera](<https://letitsee.com/guides/phone-camera-mcp>) for a nearby object, desk, or overhead view.
- [Webcam](<https://letitsee.com/guides/webcam-mcp>) for a built-in or standard USB camera on your computer.
- [USB microscope](<https://letitsee.com/guides/usb-microscope-mcp>) when the browser can see its standard webcam feed.
- [Screen, window, or tab](<https://letitsee.com/guides/screen-sharing-mcp>) when the material is already on your desktop.

The task guides also work with manually attached photos or screenshots. To request images through LetItSee, your MCP client needs remote Streamable HTTP, OAuth, and image-result support. You choose the source and request each image. LetItSee does not continuously send a camera or screen feed.

[Read the full setup and tool reference](https://letitsee.com/for-agents) before adding the MCP endpoint.

Opening the capture page is a separate action that lets you choose a source and can replace the active page for your account. [Open camera page](<https://letitsee.com/live>) only when you are ready to sign in and select that source.
