Lenso.ai

Lenso.ai is an AI reverse image search service that uses an uploaded picture to find people, places, duplicates, related images, and similar images. Searches can be refined with text keywords or a website domain, while results can be saved to profile collections and may include source URLs. A free account allows daily searches, but does not let users unlock results or view sources. Starter provides 50 source-link unlocks and 10 alerts; Professional adds Research Mode, advanced filters, and DMCA Assist Mode. Research Mode can show up to 10,000 results in the People and Duplicates categories. The Developer plan lists Face Search and Reverse Image Search APIs, with up to 5,000 API calls. Face search is available only in selected regions; API users must live where the feature is available and sign an agreement. Lenso.ai says uploaded images are not saved or shared and are not used for AI training. Paid plans are listed from $19.99/mo. The service says reverse image search works in browsers on Android, iOS, Mac, Windows, and Linux.

Lenso.ai offers image search, result-saving, alerts, and paid tools for source access and deeper research. The free account is limited to searching without unlocking results, and face-search access depends on location.

Lenso.ai suits people looking for image matches, source links, or alerts for new results. Developers may consider it for image-search APIs, subject to regional availability for face search.

Overview

Lenso.ai is a reverse image search service for tracking images across the web, from places and duplicates to people and visually similar pictures. It is best suited to users who need to investigate matches over time or refine searches beyond a basic lookup. Its main trade-off is clear: free searches can surface results, but source access and deeper research require a paid plan.

Key features

Image search and source access

Upload a picture to search People, Places, Duplicates, Similar, and Related categories; text keywords or a website domain can narrow the search. Results include source URLs, but free users cannot unlock results to view those sources. That makes the free tier useful for discovery, not for following a match back to its origin. Starter allows up to 50 source unlocks, a meaningful allowance for occasional tracing.

Face search, filters, and alerts

Face Search can locate online appearances of a face, but it is available only in selected regions. That geographic restriction makes Lenso a poor choice when face lookup must work regardless of location. Professional adds language, date-range, image-size, domain, and page-title keyword filters, which help narrow broad results, plus Research Mode for up to 10,000 People and Duplicates results. Email alerts cover new image results, with allowances of 10 on Starter and 50 on Professional.

Collections, sharing, and privacy

Users can save results to profile collections. Shared search links last up to six hours after the last interaction, so they suit short-term handoffs rather than durable records. Lenso says uploaded images are not saved or shared or used to train AI, and are visible only to the uploader unless a results link is shared. Users can request removal of face images from the index or removal of account data; the maker says image-removal requests are reviewed every business day and usually completed in less than 24 hours.

Developer tools

The API searches People, Places, Duplicates, Similar, and Related categories, with sorting and domain URL filtering. Developer includes 5,000 API calls, 5,000 unlocks, 500 alerts, Research Mode, advanced filters, and priority technical support. Face Search API access is restricted to eligible regions and requires an agreement, so it is not a universal option for developers.

Pricing

Lenso.ai is freemium, with paid access from $19.99/mo. There is no free trial. The free account permits daily image searches but does not unlock results or reveal their sources, limiting its usefulness for anyone who needs to verify where an image appears.

Starter is intended for casual individual use and includes unlimited searches, 50 unlocks, and 10 alerts. Its price is custom pricing. It is the sensible step up for occasional source tracing, but it lacks the higher alert allowance, advanced filters, Research Mode, and DMCA assistance of Professional.

Professional is aimed at frequent searchers or users who need more results and filters. It includes unlimited searches, 500 unlocks, 50 alerts, Research Mode, advanced filters, and DMCA Assist Mode, which prepares a takedown request message from selected image links and sources. Its price is custom pricing. Choose it when those research and follow-up tools matter; otherwise, Starter's smaller allowances may be enough.

Developer is the API-focused plan, with 5,000 API calls, 5,000 unlocks, 500 alerts, Research Mode, advanced filters, and priority technical support. Its price is custom pricing. It fits teams building search into a product or workflow, rather than users seeking only a browser-based lookup.

Platforms

Lenso.ai supports Android, iOS, Linux, macOS, and Windows through browsers, as well as web, API, and extension access. Its privacy policy describes a Chrome extension that starts a reverse image search when the user actively selects that feature. Supported image formats are JPG, PNG, WEBP, TIFF, HEIC, and AVIF.

Who it's for

Lenso.ai fits people who need to trace image origins, monitor new matches, or sort substantial results with filters. It is less suitable for users who only need unrestricted source access at no cost, or whose face-search needs fall outside supported regions. Developers have a distinct reason to consider it through its categorized API and usage allowance.

Pros and cons

• Pros: Searches five image categories from one upload, with keyword and domain refinement, making it useful for more than exact duplicates.
• Pros: Paid plans combine source unlocks with alerts; Professional adds detailed filters, up to 10,000 People and Duplicates results, and takedown-message assistance.
• Pros: The API includes several search categories, filtering, usage statistics, and priority support on Developer.
• Cons: Free searches do not expose source links, so practical verification requires a paid plan.
• Cons: Face Search is region-limited, and the Face Search API additionally requires eligible residence and an agreement.
• Cons: Starter, Professional, and Developer have custom pricing, making their cost harder to compare from the monthly entry price alone.

Alternatives

Google Lens is a better fit for readers who want a free option across Android, iOS, macOS, web, and Windows rather than Lenso's paid source-unlocking and research tiers.

RIMG suits users seeking free reverse image searches on Android, iOS, or the web, without a stated usage limit.

Copyseeker is worth considering for unlimited searches and premium features at $9 a month or $90 a year.

ViSenze offers a 30-day trial of Multi-Search and AI Recommendations for users who want to request a demo before choosing a paid service.

Watson may suit occasional iOS users who prefer buying search credits, with one free credit and additional credits sold individually or in a pack of five.

Syte is another paid option for web and Android.

Cloudinary may be a better match for API-oriented users who want a free tier with 3 users, 1 account, and 25 monthly credits.

Verdict

Choose Lenso.ai if you need to investigate image matches with source unlocking, recurring alerts, and deeper filters, or want an API spanning several image categories. The free tier is too restricted for source verification, and regional limits make face search a conditional rather than universal strength. If you only need free basic lookups, a free alternative is the better starting point.
