As of 13 August 2026, AI can choose blackout blinds for your bedroom.

What to actually do

1. Do it yourself

   The route this page recommends

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open a notes app and record the window type, number of windows, and whether each measurement will be inside the recess or across the outside area.
   2. Measure each window in millimetres according to the retailer's measurement guidance, recording width and drop at the relevant points and noting handles, vents, opening sections and obstructions.
   3. Write down how dark you want the room, how often you open the window, your preferred style and colour, your budget, and whether you will fit the blinds yourself.
   4. Paste the recorded details into the prompt and answer any follow-up questions the chatbot asks before accepting its shortlist.
   5. Open the product pages for the suggested blinds and compare their fabric description, fitting dimensions, side and top light gaps, controls, safety information, delivery details and return terms with the chatbot's claims.
   6. Send your measurements and the shortlisted product details to the chosen retailer or fitter for confirmation, then buy only after checking that the product and fitting method suit the window.

   Prompt

   Help me choose blackout blinds for my bedroom in the UK. Use only the information I provide and do not invent product specifications, prices, measurements or availability. Ask me for any missing information before recommending anything. My details are:
   
   Window type and number of windows: [for example, one recessed window or two windows]
   Width and drop of each window, with measurements in millimetres: [insert measurements]
   Whether the measurements are for the recess or the full outside area: [insert answer]
   Window opening, handles, vents and obstructions: [insert details]
   Current curtain or blind and what is wrong with it: [insert details]
   How dark I need the room: [for example, as dark as reasonably possible]
   Whether I need the window to open easily: [insert answer]
   Bedroom style and preferred colours: [insert details]
   Budget per window or total budget: [insert amount in pounds]
   Whether I will fit the blinds myself: [insert answer]
   
   Give me three suitable blind types or configurations, ranked by fit for my needs. For each one, explain the likely light gaps, fitting position, measurement risks, privacy, ease of use, appearance and any safety points. Distinguish true blackout fabric from blackout performance after fitting. Do not claim that any blind will improve a health condition or cure a sleep problem. Give me a short checklist of product specifications, measurements and retailer questions to verify before buying. Flag anything that needs a retailer or professional fitter to confirm.

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

2. Use a tool built for this

   Second choice

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
