Lenso.ai

Overview

Lenso.ai is a reverse image search service for tracing people, places, duplicates, related images, and visual lookalikes across the web. It is best suited to people who need to follow up on matches with source links, alerts, or more targeted searches. Its free tier is useful for discovery, but not for seeing where results came from.

Search begins with an uploaded image and can be narrowed with text keywords or a website domain. Supported formats include JPG, PNG, WEBP, TIFF, HEIC, and AVIF. Users can save results to profile collections, while shared search links stay active for up to six hours after the last interaction—handy for a quick handoff, not a permanent record.

Key features

Image and face search

Lenso searches across People, Places, Duplicates, Similar, and Related categories. Face Search can find online appearances of a face, but it is limited to selected regions. That restriction makes it unsuitable as a dependable option for people who need the same face-search access wherever they are. Face Search API users must also live in an eligible region and sign an agreement.

Sources, filters, and alerts

Results include source URLs, but the free account cannot unlock results or view those sources. Starter provides up to 50 unlocks, enough to investigate selected matches rather than treat every result as a lead. Professional adds filters for language, date range, image size, domain, and keywords in page titles; these are useful when broad visual matches need narrowing. Email alerts cover new matches, with up to 10 on Starter and 50 on Professional.

Research and takedown support

Professional’s Research Mode can show up to 10,000 results for People and Duplicates, a substantial step up for recurring searches. Its DMCA Assist Mode prepares a takedown request message from image links and sources the user selects. That can help organize a response to an image use, but it is not a substitute for deciding whether a claim is appropriate or pursuing it.

API access

The Developer plan includes Face Search and Reverse Image Search APIs, up to 5,000 API calls, 5,000 unlocks, 500 alerts, Research Mode, advanced filters, usage statistics, and priority technical support. API searches cover People, Places, Duplicates, Similar, and Related, with sorting and domain URL filtering. It is the plan for integrating search into a product or workflow; casual searchers are better served by the web-facing plans.

Privacy and control

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 request account-data removal. The maker 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 data controller and says it applies technical and organizational safeguards and follows GDPR and UK GDPR principles.

The Chrome extension can start a reverse image search from a webpage when the user actively selects the feature. Lenso says searches are also available in browsers on Android, iOS, Mac, Windows, and Linux.

Pricing

Lenso.ai is freemium, with paid access from $19.99/mo. There is no free trial. The free account allows daily image searches, but it cannot unlock results or reveal their sources, so it is an initial screening option rather than a complete investigation tool.

Starter

Starter includes 50 unlocks, up to 10 email alerts, and unlimited searches. The price is custom pricing. It is positioned for individual casual users and makes sense when a user needs source access for a limited number of matches without Professional’s research and filtering tools.

Professional

Professional includes 500 unlocks, up to 50 alerts, unlimited searches, Research Mode, advanced filters, and DMCA Assist Mode. The price is custom pricing. It suits frequent searchers who need to sift larger result sets or monitor new matches; compared with Starter, it adds 450 unlocks, 40 alerts, and the research, filter, and takedown-preparation features.

Developer

Developer includes 5,000 API calls, 5,000 unlocks, 500 alerts, Research Mode, advanced filters, usage statistics, and priority technical support. The price is custom pricing. Its API allowance and support make it the relevant choice for integration, not simply a larger personal-search package. The paid starting price is $19.99/mo, but the plan-specific prices are custom pricing.

Platforms

Lenso.ai lists support for web, Android, iOS, macOS, Windows, Linux, browser extension, and API. Its browser-based search is available on Android, iOS, Mac, Windows, and Linux. The extension is described as a Chrome extension for initiating a search from a webpage.

Who it's for

Lenso.ai is a sensible fit for image owners, researchers, or frequent searchers who need to locate online appearances and then inspect sources, monitor new matches, or narrow results with filters. Professional is the stronger fit when research volume and recurring alerts matter; Developer is for teams or products that need API search and usage support. People who only want occasional lookups may find the free tier too limited because it withholds source links, while anyone requiring face search should first confirm regional eligibility.

Pros and cons

• Useful search breadth: People, Places, Duplicates, Similar, and Related categories cover more than straightforward duplicate matching.
• Follow-up tools on paid plans: Source unlocks, alerts, filtering, and Research Mode help turn matches into an ongoing search workflow.
• Privacy controls: The maker says uploads are not saved, shared, or used for AI training, and users can request index removal or account-data removal.
• Free tier stops short of verification: Daily searches do not include unlocking results or viewing sources, limiting how much a free user can establish about a match.
• Face search is region-dependent: It is not a reliable choice for users whose location is outside supported regions.
• Plan costs are opaque beyond the entry point: Paid access starts at $19.99/mo, but the Starter, Professional, and Developer prices are custom pricing.
• Shared links are temporary: They last only up to six hours from the last interaction, so users should not rely on them as durable records.

Alternatives

Google Lens is a straightforward alternative for users who want a free image-search option across Android, iOS, macOS, web, and Windows rather than Lenso’s paid unlock and research tiers.

Copyseeker is worth considering when unlimited searches and priority speed matter more than Lenso’s stated research, filtering, and alert allowances; its Monthly plan is $9 a month.

Imagga Visual Search may suit API users looking for a broader visual toolkit that includes visual search, background removal, barcode recognition, and OCR/text recognition; its Indie plan is $79 a month.

RIMG is an alternative for people seeking free reverse image searches on Android, iOS, or the web.

Berify is another web-based freemium option for basic reverse image search, with a free tier and a free trial.

Cloudinary is an alternative for users looking for an API and extension alongside its web platform, with a free plan that includes 3 Users / 1 Account and 25 monthly credits.

FaceCheck.ID is another face-search option, with one-time credit plans including a 19.00 USD Rookie Sleuth tier.

Pixsy is an alternative for image owners who want image monitoring and case submission, with its free plan covering 500 monitored images and unlimited case submission.

Verdict

Choose Lenso.ai if you need reverse image search with source unlocking, alerts, and a route from personal searching to API integration. Its strongest case is the paid toolkit for following matches through research and monitoring. Look elsewhere if you need a fully useful free workflow, transparent plan-by-plan pricing, or face search that works regardless of region.
