Felo Search

Felo Search is an AI-driven search engine that looks across the web and presents information as understandable answers with numbered footnotes linking to sources. It accepts natural-language queries and searches in real time. Quick Search is designed for fast answers, while Professional Search examines a question from multiple angles and may ask follow-up questions. Results can include image and video blocks in a sidebar. Users can upload TXT, Word or PDF files up to 25 MB for analysis. Free users can analyze up to three files each day, one per question, with up to one million words processed. The Free plan includes five professional searches per day. The Professional Version costs $14.99 per month and allows 100 professional searches per day, with unlimited file analyses per day. Uploaded files are retained for seven days; Felo Pro files are retained permanently, according to its file-upload FAQ. Felo Search is available on Android, iOS and the web. The service's cloud security policy describes TLS 1.3 or higher for data in transit and AES-256 encryption at rest.

Felo Search combines web answers with source footnotes and file analysis, with distinct daily limits for free and paid use. Consider its file formats, upload retention and search allowances when choosing a plan.

Felo Search may suit people who want web answers with linked footnotes or need to analyze supported document formats. Its free tier may fit occasional searches and limited file analysis; heavier use requires the paid plan.

Felo Search is an AI search engine that converts live web results into explained answers with numbered footnotes. It is best suited to researchers, students, and professionals who need both current information and analysis of their own documents. The free tier works for occasional use; frequent deep searches or permanent file storage point to the paid plan.

Overview

Felo accepts natural-language questions, searches the internet in real time, and summarizes the results in a form that is easier to follow than a conventional results page. Numbered footnotes link each answer back to sources, giving readers a practical way to verify claims. Source filters, a browser extension, API access, and a deep-research mode make it useful beyond one-off browsing.

Quick Search is the fast option for straightforward questions. Professional Search considers a question from multiple dimensions and can ask follow-up questions, so it is the stronger choice for ambiguous or research-heavy work. The distinction matters on the free plan, where professional searches are capped daily.

Key features

Web, image, and video search

Live web searching makes Felo a fit for topics that change over time. Related image and video blocks can appear in a right-hand sidebar, adding visual references when a text summary is not enough. The footnote approach is a meaningful advantage for anyone who needs to check where an answer came from.

File analysis

Felo accepts TXT, Word, and PDF uploads up to 25 MB. Each question can use one file, and the service can process up to one million words. That supports asking focused questions of a report, paper, or contract, but the one-file-per-question rule makes cross-document comparison less direct. Free accounts can analyze up to three files per day, which is adequate for occasional document work but restrictive for a document-heavy workflow.

Retention and security

Standard uploaded files are retained for seven days; Felo Pro files are retained permanently. That longer retention is useful when a project spans weeks, while the shorter period on free use favors temporary analysis. Felo describes TLS 1.3 or higher for data in transit and AES-256 at rest. Its cloud-security policy says it aims to comply with, or is promoting, ISO/IEC 27001, SOC 2 Type I, and Japan’s Act on the Protection of Personal Information. The privacy policy covers personal information used through its website, applications, and services; API business content is handled under customer agreements instead.

Pricing

The Free plan is the sensible starting point for light research and occasional uploads, but five Professional Searches per day can disappear quickly for serious investigation. At $14.99 per month, Professional Version is aimed at regular researchers who need 100 daily deep searches and unlimited daily file analyses. It also includes permanent file retention, unlike the seven-day standard retention. Felo does not publish a multi-seat structure in these plans, so this pricing is best read as an individual subscription. Payments are processed through Stripe, with Visa, MasterCard, and AMEX credit or debit cards accepted.

Platforms

Felo Search runs on the web and has Android and iOS apps. Felo’s version history describes redesigned interfaces for both mobile applications, making the service suitable for users who move between desktop browsing and phone-based searches.

Who it's for

Choose Felo if you want current web answers with citations and also need to question your own TXT, Word, or PDF files. Students and analysts benefit from the professional mode’s multi-angle questioning, while teams building workflows may value API access. It is less suitable if you routinely compare many documents in one question or need a free plan with a large daily research allowance.

Pros and cons

• Pro: Real-time search and numbered footnotes make answers easier to verify.
• Pro: Professional Search can examine multiple dimensions and ask follow-up questions.
• Pro: Uploads support TXT, Word, and PDF files up to 25 MB, with one-million-word processing capacity.
• Pro: Professional Version combines 100 daily professional searches with unlimited daily file analyses.
• Con: Free use is limited to five professional searches and three file analyses per day.
• Con: One file per question limits direct cross-document analysis.
• Con: Standard uploads last seven days, so ongoing projects need the paid plan’s permanent retention.

Alternatives

Perplexity is the better fit if you want a broader platform footprint, including macOS and Windows, or a $20-per-month Pro plan for serious work.

Andi AI suits readers who prioritize unlimited searches on a free plan, along with reading, summarizing, and explaining tools.

Consensus is preferable for paper-focused research, offering unlimited paper searches and three deep reviews per month on its free tier.

Genspark Design is a better match for users seeking a broader AI workspace with daily credits and AI Drive storage.

SciSpace is the specialist choice when academic-paper workflows and study tools matter more than general web search.

Yahoo Scout is a free option for readers who want no paid subscription required at launch.

You.com is worth considering if a 100-query daily free allowance and API-oriented options are more important than Felo’s file limits.

Arc Search fits readers who primarily want a free mobile browser rather than a document-analysis service.

Verdict

Felo Search is a strong choice for people who need explainable, up-to-date web answers alongside questions about their own files. The $14.99 Professional Version earns its place for sustained research through higher professional-search limits, unlimited daily file analyses, and permanent retention. Look elsewhere if your priority is unlimited free searching, extensive cross-platform coverage, or a workflow built around comparing several documents at once.
