Software Usage Instructions

Select a work mode: The tool provides three modes to choose from
- Single mode: Suitable for detailed operations. You can set multiple keyword groups and use advanced options such as prefixes and suffixes, text conversion, excluded word filtering, length limits, random sampling, and more
- Batch mode: Suitable for quickly processing large numbers of keywords. Enter one group of keywords per line to generate in batches. Prefix/suffix and filtering features are also supported
- History: Automatically saves the last 20 generated records. You can restore previous configuration parameters with one click to quickly generate again
Enter keyword groups:
- Single mode: Enter one keyword per line in each group input box. Click the "+ Add more groups" button to add keyword groups, and click "🧹 Clean all groups" to automatically remove duplicate words and blank lines
- Batch mode: Enter one group of keywords per line in the text box, with keywords within a group separated by commas
- File import: There is a "📁 Import" button in the upper-right corner of each group input box. It supports importing keywords from TXT, CSV, and Excel files; batch mode supports drag-and-drop file import
Select a combination method:
- All combinations: Generate all possible keyword combinations (Cartesian product)
- Sequential combination: Take one keyword from each group in order to create combinations
- Pairwise combination: Combine keywords from any two groups only
- Custom template: Use placeholders such as {1}, {2}, {3} to customize the combination format. For example, "{1}+{2}-{3}" gives you full control over the combination structure and separators
Set a separator: Choose the connector between keywords. Spaces, hyphens, underscores, commas, vertical bars, no separator, and any custom separator are supported
Configure advanced options:
- Remove duplicate results: Automatically delete duplicate combinations
- Unordered deduplication: Treat "A B" and "B A" as the same combination for deduplication, suitable for scenarios where order does not matter
- Sort alphabetically: Sort results in alphabetical order (supports Chinese sorting)
- Reverse combination order: Reverse the order of keywords in combinations
- Text conversion: Choose all lowercase, uppercase, capitalize first letter, or title case
- Random sampling: After setting a number, only the specified number of results will be randomly selected, suitable for testing or sampling scenarios
- Add prefix/suffix: Add uniform prefix or suffix text to all combinations
Filtering options:
- Excluded words: Enter excluded keywords (one per line). Combinations containing these words will be automatically filtered out
- Length limit: Set the minimum/maximum character length of combination results. Combinations outside the range will be automatically filtered out
Real-time preview: When entering keywords, the tool displays the estimated number of combinations and the first few preview results in real time, so you can estimate the effect without clicking Generate
Generate results: After clicking the Generate button, the system automatically generates all combinations and displays statistics (number of combinations, number of groups, total keywords, number filtered). When the estimate exceeds 100,000 entries, a confirmation prompt will appear to prevent the browser from freezing
Export results: Supports five methods: copy all, download TXT, CSV, JSON, and Excel. Results support paginated browsing (100/500/1000/5000 items per page), making it easy to view large amounts of data

FAQ

A: Full combination generates all possible keyword permutations and combinations (Cartesian product), suitable for scenarios where all possibilities need to be exhausted; sequential combination takes one keyword from each group in order to form combinations, with the number generated equal to the number of keywords in the longest group; pairwise combination only pairs any two keyword groups, suitable for simple keyword pairing needs; custom template lets you freely define the combination format using placeholders such as {1}, {2}, and {3}. For example, "{1}色{2}({3})" can generate a custom structure like "红色连衣裙(夏季)". For example, if 3 keyword groups each have 3 words, full combination generates 27 results, sequential combination generates 3, and pairwise combination generates 27.

A: The prefix and suffix features can add fixed text uniformly to all generated keyword combinations. For example, if the prefix is set to "2024" and the suffix to "style", the generated "red dress" will become "2024 red dress style". This feature is especially suitable for e-commerce product title optimization, year labels, model additions, and similar scenarios. Both single mode and batch mode support this feature.

A: In theory, there is no quantity limit, but when more than 100,000 combinations are expected to be generated, the system will show a confirmation prompt to prevent the browser from freezing. Results are displayed with pagination (optional 100/500/1000/5000 items per page), and the complete results can be obtained by downloading the file. If the number of results is too large, we recommend using exclude-word filtering, length limits, or random sampling to reduce the results.

A: Single mode is suitable for scenarios that require fine-grained control, offering more advanced options such as custom templates, unordered deduplication, reverse order, and random sampling. Each keyword group is entered separately for easier management; batch mode is suitable for quickly processing large numbers of keyword groups, with simpler and more efficient operation. It supports drag-and-drop file import and is ideal for batch processing needs where keyword lists have already been organized. Both modes support prefixes and suffixes, exclude-word filtering, and length limits.

A: The tool provides multiple deduplication mechanisms: 1) Click "🧹 Clean All Groups" to remove duplicate words and blank lines within each group before generating; 2) The "Remove Duplicate Results" option is enabled by default, automatically deleting completely identical combinations; 3) After enabling the "Unordered Deduplication" option, "red dress" and "dress red" will be treated as the same combination, and only one will be kept. It is recommended to clean the data first when entering it, then choose the appropriate deduplication method as needed.

A: The exclusion words feature allows you to set keywords you do not want to appear (one per line). Any generated combination containing an exclusion word will be automatically filtered out. For example, if you exclude "black winter", all combinations containing that term will not appear in the results. Length limits let you set the minimum and maximum character length of the combined results. Combinations outside the range are automatically filtered out, making this suitable for scenarios with keyword length requirements (such as character limits for search engine ad titles). The number filtered out will be shown in the statistics.

A: The tool supports importing keywords from TXT, CSV, and Excel (.xlsx/.xls) files. In single mode, there is a "📁 Import" button in the upper-right corner of each group input box. Click it and select a file to import its content into the corresponding group. In batch mode, you can click or drag files into the import area. For TXT files, each line is treated as one keyword; for CSV files, the first column of each row is used; for Excel files, the first column of the first worksheet is used. After importing, you can continue to edit and adjust the content manually.

A: The tool automatically saves the most recent 20 generation records (stored locally in your browser and not uploaded to the server). Switch to the "History" tab to view all records, including time, combination method, number of results, and other information. Click any record to restore the keywords and configuration parameters from that time with one click, making it easy to regenerate or fine-tune quickly. Click "Clear History" to delete all records.

A: The tool supports five export methods: Copy All copies directly to the clipboard for easy pasting; TXT File is a plain text format with one keyword per line, ideal for direct use; CSV File is suitable for opening and editing in spreadsheet software such as Excel and Google Sheets; JSON File is a structured data format that includes metadata such as generation time and total count, suitable for programmatic use; Excel File (.xlsx) includes a numbered column, suitable for office scenarios and data management. Simply choose the appropriate format based on your use case.

A: When the number of results generated by all combinations is very large, the random sampling feature can randomly select a specified number of results from them. Applicable scenarios include: needing only a small sample when testing keyword performance, randomly selecting a batch from a large number of combinations for ad placement testing, quickly previewing combination quality without needing all results, and more. Enter a number to limit the output quantity, or leave it blank to output all results.
