About Fluven
A name built from two ideas: flow and green.
Fluven is a coined word: fluide (French: fluid, flowing, effortless) meets vert (French: green), softened to -ven. Neither word appears in the name. Both ideas live inside it: seamless motion and deep sustainability, without announcing either.
That duality is the product. Our mission: make sustainable shopping effortless.
Product
Sustainability intelligence, built into your browser.
Fluven is a Chrome extension that scores Amazon products in real time across three sustainability dimensions. No tabs to open, no databases to search.
Instant scoring
Every Amazon product page triggers real-time sustainability analysis using Claude AI. Scores appear as a floating overlay, no extra clicks, no waiting.
Top Pick
On search result pages, Fluven surfaces the single most sustainable option, grounded in the same scores you see on the page, so better choices take zero extra effort.
Greener alternatives
When a product scores low, Fluven surfaces a higher-scoring alternative right away, so switching to a better option takes one click.

How a score is built
Four steps, applied to every product Fluven evaluates.
Category detection
Every product is routed to one of 7 category rubrics (food and grocery, electronics, apparel, beauty and household, home and furniture, books and office, general) so products are judged against fair peers.
Category baseline
Each category starts from a research-based baseline: certified organic food starts at 70, books at 70, refurbished electronics at 65, conventional food at 58, new electronics at 33, synthetic-fiber apparel at 33.
Evidence-based adjustments
Only facts visibly stated on the product page count. Certifications add points (Fair Trade +15, Cradle to Cradle +15, ENERGY STAR +12, Carbon Neutral +12, FSC +10, GOTS +12, refillable or concentrate formats +10) and red flags subtract (single-use plastics -18, ultra-fast fashion brands -20, palm oil without RSPO certification -8). Nothing is inferred: if a certification is not printed on the page, it does not count.
Weighted verdict
Overall = 40% carbon + 30% waste + 30% ethics. 65-100 is Great Choice, 40-64 is It's OK, below 40 is Worth Avoiding.
A few examples
What keeps scores honest
Scoring is deterministic, the same product always gets the same score. Food products are cross-checked against the Open Food Facts Eco-Score database when available, and scores note only facts present in the product listing.
