How to choose AI Search tools
Both return sourced answers to typed questions. iAsk.Ai has a free plan and a Pro plan at $9.95 a month; Perplexity's Pro plan is $20 a month. lenso.ai and PimEyes run reverse image and face searches; lenso.ai has a free plan, PimEyes offers a free search per visit. FaceCheck.ID does the same but is paid only, with no free tier at all.
Two things separate these tools more than anything else. The first is what kind of search is needed: typed questions, uploaded images, or fraud checks. The second is cost before any result arrives. iAsk.Ai, Perplexity, lenso.ai, and Komo AI all have free plans to start with. FaceCheck.ID requires buying credits before a single search runs, and AddSearch starts at $119 a month billed annually, making both the most expensive entry points here. Komo AI is the only tool that publishes every plan price outright, from $15 to $200 a month.
Which kind of search fits the task
iAsk.Ai and Perplexity answer typed questions and return sources alongside the answer. Both have free plans. Komo AI does the same and adds a topic-exploration mode with an ad-free interface. Its paid plans run from $15 to $30 a month, with a business tier at $200 a month. For image-based work, lenso.ai finds where an image appears online and can match faces across photos. PimEyes limits searches by its terms to a person looking for their own face. FaceCheck.ID adds a database of flagged accounts and scammers, starting at $19 for 14 days.
What each tool costs before results arrive
iAsk.Ai, Perplexity, lenso.ai, Komo AI, and PimEyes all let a search run before any payment is needed. iAsk.Ai's free plan includes unlimited daily searches. Perplexity's free plan has no published search cap. FaceCheck.ID has no free tier; credits must be purchased first, starting at $19 for 14 days, and payments are accepted only in cryptocurrency. AddSearch starts at $119 a month billed annually, the highest published entry price here. Bonsai, which runs managed search clusters for developers, starts at $25 a month but scales to $5,500 a month at the enterprise level. lenso.ai and GigaBrain Pro both list their premium prices as contact sales rather than publishing a number.
How much each tool publishes about its pricing
Komo AI is the clearest: $15 a month for the basic plan, $30 for premium, $200 for business, all published on the site. iAsk.Ai puts its Pro plan at $9.95 a month. Perplexity puts its professional plan at $20 a month. FaceCheck.ID publishes its credit packages, from $19 for 14 days to $597 for a year. Bonsai publishes its standard and business ranges. lenso.ai, PimEyes, and GigaBrain Pro give no price without a sales contact, which makes them harder to compare against the tools that do publish. AddSearch publishes $119 a month for keyword search and $700 a month for its AI answers tier, but its conversational tier requires a sales call.
