# Troubleshoot a second computer with an AI assistant [Read as HTML]() When a separate computer cannot share its own screen with the assistant, you can relay a selected view with a phone camera or type the relevant text yourself. This works best as a deliberate troubleshooting exchange: describe the symptom and what has changed, capture one useful view, then decide what evidence would help next. LetItSee supplies requested still images; it cannot connect to the second computer, inspect its files, or carry out repairs. ## Give the assistant the history first State which computer is affected, what stopped working, when it began, and what changed just before it. Include exact error text if you can read it, the operating system or device type when known, and which checks you have already tried. Separate observations from guesses: “the link light is off” is more useful than “the network card is broken.” This avoids repeating steps and helps the assistant ask for a targeted view. If the machine still displays a message, type the text into chat when practical. A transcription is easier to search and reason about than a small, angled screen photo. Use a camera image for details that text cannot convey, such as which port is connected, whether an indicator is lit, or the physical arrangement of equipment. ## Frame one view for one question Choose a phone camera for a nearby screen or the back of a machine. Keep the whole relevant area in frame before moving closer: a view showing the device and its connections can establish context, followed by a close-up if a label or indicator is hard to see. Avoid reflections on glossy screens, hold still, and make small text large enough to read. Say which side or component the assistant should inspect. Request a single fresh photo, then review the returned image yourself. If it is blurry, cropped, or shows the wrong side, reposition the phone and request another. Opening another capture page for the same account can replace the active page, so leave the selected phone page open while using the assistant. ## Use each observation to choose the next step Ask the assistant to describe what is visible, identify uncertain details, and suggest a low-risk next check based on the history you supplied. You remain responsible for deciding whether to try it. After a change you choose to make, report exactly what changed and what happened; capture another still only when the resulting visual state matters, such as a changed screen message or indicator. This loop keeps the assistant's reasoning tied to observed evidence rather than an assumed diagnosis. If the next useful evidence is a log, command output, network configuration, or a measured value, paste that directly instead of taking a photo. Keep a short record of steps and outcomes in the conversation so a later image has a clear baseline: symptom and time, exact visible message, check already tried, result, and next unresolved question. ## Know when a photo is the wrong evidence A still image cannot show whether a process is continuing, prove a component is electrically safe, or expose information outside the selected view. LetItSee does not control the computer, read its files, or run an unattended monitoring loop. The mobile capture page must remain visible and awake for the phone source to stay available. Use remote support software, system logs, diagnostics, or a qualified technician when the work requires direct access, continuous observation, or a safety-critical judgment. Never treat an assistant's interpretation of a photo as proof that internal hardware is safe to handle. ## Prompt to adapt > Example to adapt: Take one fresh photo of the selected screen or indicator on the second computer. Describe only what is visible, transcribe readable text exactly, and flag uncertainty. Here is the history: [symptom, when it began, check already tried, and result]. Suggest one next piece of evidence to collect; do not prescribe a command or assume the cause. Wait for me to choose a documented, permitted check and report back before requesting another image. ## Connect your source Add https://letitsee.com/mcp using remote MCP, Streamable HTTP, OAuth, and image results.
