Felo Search

Felo Search is an AI search engine for people who want current web answers explained in plain language with numbered source footnotes. It suits researchers, students, and professionals who also need to question their own documents. Its strongest case is the combination of real-time search and file analysis, but daily free quotas and differing file-retention terms should shape your choice.

Overview

Felo accepts natural-language questions, searches the web in real time, and turns results into understandable answers with numbered footnotes that lead to sources. That makes it more useful than a bare list of links when you need a concise explanation you can verify. Source filters, a browser extension, API access, and a deep-research mode broaden its use beyond casual searching.

Quick Search is designed for speed. Professional Search examines a question from multiple angles and can ask follow-up questions, so it is the better option for ambiguous or research-heavy requests, while the daily professional-search allowance limits how often free users can rely on it.

Key features

Web and media search

Answers are built from current web results rather than a fixed index. Related image and video blocks can appear in a right sidebar, which is useful when a topic benefits from visual references as well as text.

Document analysis

You can upload TXT, Word, or PDF files up to 25 MB. Each question can use one file, and processing supports up to one million words. Free accounts can analyze three files per day; Professional accounts remove the daily file-analysis limit. Uploaded files are retained for seven days, while Felo Pro files are retained permanently, an important distinction for confidential or repeatedly used material.

Security and privacy

Felo describes TLS 1.3 or higher for data in transit and AES-256 for data at rest. Its cloud-security policy says it aims to comply with, or is promoting compliance with, 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. Contact Felo if an inaccessible or security-sensitive account email needs changing.

Pricing

The free tier is suitable for occasional questions and light document work, but five Professional Searches and three analyses can disappear quickly in a working day. At $14.99 per month, Professional is aimed at regular researchers who need substantially more intensive search and unlimited daily file analysis. It is not the right upgrade solely for occasional browsing. Payments run 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. The mobile version history describes a redesigned interface on both platforms, making it practical for users who move between desktop and phone. The service also offers a browser extension and API access for workflows beyond the main apps.

Who it's for

Choose Felo if you need current, source-linked explanations, want a deeper search mode for complex questions, or regularly interrogate PDFs, Word files, and text documents. Professional is the sensible fit for sustained document analysis or frequent multi-angle searches. Users handling files that must remain available should account for the seven-day free retention versus permanent retention for Felo Pro. Casual users who rarely exceed a few searches or uploads can stay on Free.

Pros and cons

• Pros: Real-time web search with numbered footnotes makes answers easier to check; Professional Search can pursue multiple dimensions and ask follow-ups; support for TXT, Word, and PDF files reaches one million words; image and video result blocks add context; web, mobile, extension, and API access cover varied workflows.
• Cons: Free users get only five Professional Searches and three file analyses per day; one file per question restricts multi-document queries; the 25 MB upload ceiling excludes larger files; seven-day retention on uploaded files is unsuitable for long-term free storage; permanent file retention applies to Felo Pro rather than the free tier.

Alternatives

Browse AI Search Engines for a wider comparison. Pick Perplexity instead if you want apps across Android, iOS, macOS, Windows, web, and API, and its $20-per-month Pro plan for heavier individual use. Genspark Design is the better fit for a credit-based creative workspace, with 100 free credits daily and a Plus tier offering 10,000 monthly credits and 50 GB of AI Drive storage.

Andi AI suits readers wanting unlimited searches and free read, summarize, explain, and AI-text tools. Choose Arc Search for a free mobile-browser experience across Android and iOS, with desktop versions; future premium pricing is possible. Consensus is preferable for paper-focused work, offering unlimited paper searches on its free tier plus limited Pro messages, deep reviews, study snapshots, and API/MCP calls.

Yahoo Scout is a free general option with no paid subscription required at launch, although some features need a Yahoo account. You.com is worth choosing for 100 free queries per day, web and news results, and a $1-per-1,000-pages Contents API option. Elicit fits literature reviews, with unlimited search across more than 138 million papers and unlimited summaries on its Basic plan.

Verdict

Felo Search is a strong choice for anyone who wants verifiable, current answers and built-in analysis of common document formats, especially at the $14.99 Professional tier. Look elsewhere if your priority is unlimited free searching, larger or longer-retained files, or a specialist research database rather than a general web-and-document assistant.
