Free tool
Bought a new prompt pack and not sure how much of it you already own? Paste both lists and get one clean set with the duplicates removed.
More than one prompt? Separate them with a line of --- (three dashes). One prompt on its own is fine as it is.
Checking one prompt? Paste it here on its own, no dividers needed.
This checks two lists by hand. REPONA keeps every prompt you own in one place and skips exact duplicates automatically each time you bulk add, so the same prompt doesn't get saved twice.
Start free in REPONAIf you buy prompt packs, join prompt communities and save prompts from custom GPTs, the same prompt ends up in your collection more than once. One pack reuses a prompt from another. A community shares a prompt you saved last month. Your notes app holds three copies because you pasted it on three different days.
It seems harmless until you need one. Every copy is another result to scroll past, and when your files are named prompt 014, prompt 015 and prompt 016, you can't tell which is which without opening each one. They're just numbers.
Your two lists stay in this browser, so refreshing the page won't lose them. Press Clear all when you're done.
Two prompts count as duplicates when the text matches exactly, ignoring capital letters and extra spaces. So "Golden hour portrait, 35mm" and "golden hour portrait, 35mm" are treated as the same prompt.
Prompts that say the same thing in different words are not treated as duplicates. Only an exact match is removed, so the tool never throws away a prompt you meant to keep.
Anyone collecting image prompts from more than one place: prompt packs, communities, custom GPTs and your own experiments for Midjourney, Sora, Kling, Higgsfield, Nano Banana or Seedream. If all your prompts come from one source, you probably don't need this. If they come from five, you do.
This tool checks two lists at a time, by hand. REPONA keeps your whole library in one place and skips exact duplicates every time you bulk add prompts. Instead of scrolling through files that are just numbers, you can search the tags, the title and the prompt itself to find the one you need. Saving and searching is free forever, and links to your custom GPTs and tutorials are unlimited and free.
Paste the prompts you already have into the first box and the new prompt pack into the second, with a line of --- between each prompt. Press Find duplicates. The tool shows you which prompts you already own and gives you one combined list with each prompt appearing once. Checking a single prompt? Paste it on its own, no dividers needed.
Yes, completely free, with no sign up and no card. It runs entirely in your browser.
No. Everything happens on your own device. Your two lists are saved only in this browser so a refresh doesn't lose them, and Clear all removes them. Nothing is sent to a server.
Two prompts count as duplicates when the text matches exactly, ignoring capital letters and extra spaces. Prompts that say the same thing in different words are not treated as duplicates, so the tool never removes a prompt you meant to keep.
Only when a box holds more than one prompt. A single prompt pasted on its own works as it is. A prompt can contain blank lines, for example a title line above the prompt, so blank lines never split anything. If a box has blank lines and no dividers, the tool asks instead of guessing: check it as one prompt, or add the dashes and run it again. For a long messy list with no separators at all, REPONA's paid Smart Split works out where each prompt starts.
In a file or a pack page, you mostly can't, apart from opening each one. In REPONA every prompt gets a title and tags, and you can search the tags, the title and the prompt text at the same time. You can name prompts yourself for free, or let the paid Auto-label feature title and tag them for you.
No. Copy the combined list and paste it into Bulk add in REPONA. Because the prompts are already separated by ---, one paste saves every prompt as its own entry, and Bulk add is free.
Yes. The checker compares text, so it works the same for prompts written for Midjourney, Sora, Kling, Higgsfield, Nano Banana, Seedream or any other tool.
