Lenso.ai

Overview

Lenso.ai is a reverse image search service for people, places, duplicates, related images, and visually similar images. It suits people who need to trace an image across the web, especially when they want alerts or search controls beyond a basic lookup. Its strongest case is the combination of source unlocking, filters, and monitoring; the free account is better for occasional discovery than follow-up.

Search starts with an uploaded image and can be refined with text keywords or a website domain. Results can be saved to profile collections, and supported uploads include JPG, PNG, WEBP, TIFF, HEIC, and AVIF. Shared search links remain active for up to six hours after the last interaction, so they are useful for short-term collaboration rather than lasting records.

Key features

Image and face search

Lenso searches People, Places, Duplicates, Similar, and Related categories. Face Search can locate online appearances of a face, but access is limited to selected regions. That makes it a poor fit for anyone who needs consistent face-search coverage regardless of location.

Sources, filters, and monitoring

Results include source URLs, but a free account cannot unlock results to view those sources. Starter raises the practical value of a search by allowing up to 50 unlocks, while Professional adds language, date-range, image-size, domain, and page-title keyword filters. Those controls matter when broad visual matches need narrowing; casual users may not need them.

Email alerts can flag new image matches, with up to 10 on Starter and 50 on Professional. Collections provide a way to save results in a profile. Professional also includes DMCA Assist Mode, which prepares a takedown-request message from selected image links and sources; it helps with drafting, rather than replacing the user's decision to pursue a removal.

Research and API

Professional Research Mode can show up to 10,000 results for People and Duplicates, a substantial allowance for frequent searching. Developer includes Research Mode, advanced filters, 5,000 API calls, 5,000 unlocks, 500 alerts, usage statistics, and priority technical support. Its API covers People, Places, Duplicates, Similar, and Related searches, with sorting and domain URL filtering, making it the plan for integrating image search into a product or workflow rather than just using the site.

Privacy and removal controls

Lenso says uploaded images are not saved or shared, are not used to train AI, and remain visible only to the uploader unless a results link is shared. Users can request removal of face images from the index, withdraw consent, or ask for account data removal. The company says opt-out requests are reviewed every business day and removal usually takes less than 24 hours. Its privacy policy identifies LENSO AI SPÓŁKA AKCYJNA as the controller, describes technical and organizational safeguards, and says it follows GDPR and UK GDPR principles.

The Chrome extension starts a reverse image search from a webpage when the user actively selects that feature. That is a convenient shortcut for browser-based research, while the stated privacy controls address uploaded images rather than making broader promises about every use of the service.

Pricing

Lenso.ai is freemium, with daily image searches on the free account and paid access from $19.99/mo. Free access is limited at the point that often matters most: it does not let users unlock results or see their sources. There is no free trial, so regular use of source links requires choosing a paid plan.

Starter has custom pricing and is aimed at individual casual users. It includes unlimited searches, 50 unlocks, and 10 alerts. It is the sensible paid entry point for occasional image tracking, but its smaller unlock and alert allowances and lack of Professional's stated filters and research tools make it less suited to sustained investigations.

Professional has custom pricing and is intended for frequent searchers or people who need more results and filters. It includes unlimited searches, 500 unlocks, 50 alerts, Research Mode, advanced filters, and DMCA Assist Mode. Choose it when larger result volumes, targeted filtering, or takedown drafting justify the extra capabilities; its price is not given as a fixed amount.

Developer also has custom pricing. It bundles 5,000 API calls, 5,000 unlocks, 500 alerts, Research Mode, advanced filters, and priority technical support. This is the relevant option for API use, but API access is subject to regional eligibility for Face Search, and Face Search API users must sign an agreement. The pricing information gives no seat count or renewal term for these plans, so those should not be assumed.

Platforms

Lenso.ai supports web use and offers Android, iOS, Mac, Windows, and Linux browser access, as well as an extension and API. The Chrome extension is specifically described as initiating searches from webpages. That breadth works for people moving between desktop and mobile browsers, while the API serves teams building a separate integration.

Who it's for

Lenso.ai is best for people who need to find image appearances, verify where a picture is used, or monitor for new matches. Starter suits occasional personal searches that need source access; Professional is a better match for repeated work that benefits from filters, larger unlock capacity, and alerts. Developer is for software teams needing searchable image categories through an API. It is not the right choice for users who require face search in every region or need the free tier to reveal source URLs.

Pros and cons

• Pros: Searches across people, places, duplicates, related, and similar images from one upload, with keyword and domain refinement.
• Pros: Paid plans add source unlocking, alerts, and, at Professional level, focused filters and DMCA message preparation.
• Pros: Developer combines broad category coverage with sorting, domain filtering, usage statistics, and priority support.
• Pros: Users have image opt-out and account-data removal controls, alongside stated limits on saving and training with uploads.
• Cons: Free searching does not reveal unlocked results or their sources, restricting its usefulness for attribution.
• Cons: Face Search is region-restricted, which can rule it out for users whose work depends on that feature everywhere.
• Cons: The paid plans have custom pricing, making plan-to-plan cost comparison difficult before purchase.

Alternatives

Google Lens is the simpler pick for readers who want a free option across Android, iOS, macOS, web, and Windows; its page states no price or usage limits, while Lenso's free tier cannot expose sources.

Copyseeker is worth comparing if a published subscription price matters: its Monthly plan is $9.00 USD per month and includes unlimited searches, priority speed, and premium features. Imagga Visual Search is an alternative for API-focused users who also need image-processing capabilities such as background removal, barcode recognition, or OCR; its Indie plan is $79.00 USD per month.

RIMG is another reverse image search option. Cloudinary, FaceCheck.ID, Pixsy, and Berify are alternatives to consider.

Verdict

Choose Lenso.ai if you need more than a one-off visual lookup: its mix of source unlocking, alerts, collections, filters, and API makes it useful for ongoing image research. The main reason to look elsewhere is equally clear: free searching stops short of showing sources, paid plans use custom pricing, and face search is not available in every region.
