Frequently Asked Questions
How we find and rank alternatives to Grammarly
Semantic AlgorithmPowered by SimilarWebNo Paid Placements
We generate a semantic embedding (vector) for every AI tool in our database. Alternatives are found by first narrowing candidates to tools in the same categories, then ranking by cosine similarity score. Only tools with a similarity score ≥ 0.52 make the cut — ensuring every recommendation is genuinely related, not just popular in the same broad category.
The full list (up to 20 tools) is ordered by semantic similarity — the most functionally similar tools appear first. "Quick Comparison" goes one step further: it takes the top candidates from that list and re-ranks them by monthly traffic, giving you a fast snapshot of the most widely-used options right now.
Quick Comparison has fewer slots and adds a traffic threshold on top of similarity. A tool can be highly similar to the one you are looking at but still have lower monthly traffic than other candidates — it stays in the full list where you can still discover and evaluate it.
Monthly visits, growth rates, and regional distribution data are sourced from SimilarWeb via our licensed API. SimilarWeb is the industry-standard web analytics service used by analysts, investors, and product teams worldwide. The data month is displayed at the bottom of the Quick Comparison table.
Similarity relationships are recalculated periodically as new tools are added to our database. Traffic metrics (visits, growth rate, top market) are refreshed monthly from SimilarWeb. The exact data month is always shown at the bottom of the Quick Comparison table so you know how fresh the numbers are.
No. The order of results is determined entirely by our similarity algorithm and third-party traffic data. We do not sell placement positions in alternative lists or Quick Comparison tables. If a tool is listed here, it earned its place through data — not through advertising spend.
