Helium 10 is a data tool — it shows you search volume, BSR, competitor rank data pulled from Amazon. Keyword Booster is an AI tool — it generates, cleans, formats and builds listings using AI. They complement each other. Use Helium 10 to find keywords with data, then bring them into Keyword Booster to clean, format, match type, and build your listing — especially in local languages Helium 10 doesn't support.
16 languages: English, Hindi/Hinglish, Tamil, Telugu, Kannada, Malayalam, Bengali, Marathi (all Amazon.in official languages), German, French, Italian, Spanish, Dutch, Polish, Japanese, Arabic and Portuguese. All languages work across every AI feature — Suggest, Expand, Clean, Match Types, Competitor Spy, SEO Titles, Listing Builder and more.
Amazon's backend search terms field accepts a maximum of 249 bytes. Each letter or number = 1 byte. Spaces don't count. Keyword Booster shows a live byte counter and auto-trims to stay under the limit. The AI backend generator also ensures output is always under 249 bytes with no commas, no duplicate words, and no stop words.
Yes. Non-AI processing rules (clean, format, deduplicate) work on unlimited keywords instantly. AI features process up to ~6,000 keywords per call for optimal results. The tool handles large bulk keyword lists from Helium 10, Brand Analytics, or any other source.
A two-layer check that runs on your generated listing before you publish. Layer 1 (instant, free): checks title length, prohibited words like "best" or "guaranteed", excessive caps, special characters, backend byte limit, comma usage, and description length. Layer 2 (AI): checks for unauthorized health claims, misleading statements, and competitor brand mentions. Auto-fix buttons fix most violations in one click.
Monthly plan credits reset each month — they don't roll over. Daily bonus credits expire at midnight. Top-up credits (bought separately) are valid for 1 full year from purchase. Credit deduction order: daily first → monthly → top-up (oldest expiry first).
Yes — and it's the best option for Indian sellers. Keyword Booster is the only keyword tool that supports all 7 official Amazon.in languages: Hindi, Tamil, Telugu, Kannada, Malayalam, Bengali and Marathi. Generate real local-language keywords that Indian buyers actually search for — not just English keywords translated.
