We may earn a commission if you buy through links on this page. It never changes a score or a ranking. How we make money
Genspark is our best all-around starting point for buyers who want search and document work in one workspace; Elicit and Connected Papers are stronger for literature research, while QAnswer suits teams that prioritize private deployment. There is no single AI search engine that fits every job—or a clear winner over Google for every query. We ranked these tools by fit, listed price and how clearly buyers can assess the cost. Treat “from” prices as starting points, and check plan limits before switching.

- Best for AI apps
You.comYou.comYou.com stands out for teams building AI search applications, with MCP web search and model-provider failover among its stated use cases. A free MCP tier lowers the barrier to trying it, but pricing is not published on the vendor's site. It suits builders better than buyers seeking a ready-made company knowledge search product.

Its scope is deliberately narrower than a general research search product: use it to discover related papers, not as a replacement for broader literature search or review workflows.
What works
- Visual graphs make related work easier to explore
- Surfaces prior and recent papers
- Can help identify bibliography gaps
What doesn't
- Free plan is capped at five graphs monthly

- Agents cover research, investment analysis and valuation
- Results are described as backed by verified data
What doesn't
- Plans list one seat each

- Free plan includes 10 monthly AI Copilot prompts
- Pro includes 15 years of financial data
What doesn't
- Pro costs $49 monthly or $39/month annually

- Best for finance teams
AlphaSenseAlphaSenseAlphaSense focuses on finance and strategy research, including cited research and workflows in Excel and PowerPoint. The published summary describes its pricing as custom and opaque, so there is no listed starting price to compare. Its finance features may suit institutional research teams, but buyers should request a full quote and usage terms before evaluating value.
What works
- Searches filings, broker research and expert transcripts
- AI search spans curated financial and business sources
- Homepage says answers include sentence-level citations
What doesn't
- Both listed plans require a custom quote
- Starting price and billing details are not published
- Pricing notes list no free plan

- Best for company knowledge
GleanGleanGlean is designed for large teams with scattered company knowledge, permission-aware AI search and governed AI workflows. The published summary calls out strong enterprise search and agents, but also opaque contract pricing and usage fees. Pricing is not published on the vendor's site, making it harder to compare switching costs without a detailed quote.
What works
- Searches company documents and knowledge across connected apps
- Permission-aware access limits users to authorized information
- Supports 40+ LLMs and task-matched reasoning levels
What doesn't
- Starting price and contract terms are not published
- No free plan is listed
- Enterprise Flex Thinking Mode has a weekly per-user cap

- Best for enterprise search
CoveoCoveoCoveo is aimed at organizations consolidating search, commerce teams seeking personalized recommendations, and teams requiring permission-aware retrieval. The published material does not publish pricing, which makes the cost of switching hard to assess. It belongs on an enterprise shortlist when those capabilities match the requirement, but request pricing before comparing it with alternatives.
What works
- Hybrid search combines vector retrieval and keyword search.
- Generative answers cite enterprise content.
- Search Agent supports multi-turn conversations.
What doesn't
- Exact subscription prices are not published.
- Subscriptions use annual or three-year agreements.
- Each listed plan includes 100,000 monthly queries.

- Best for deal research
HebbiaHebbiaHebbia targets institutional research teams, deal teams working across firm documents, and firms seeking structured company research. Pricing is not published on the vendor's site. Reported answer reliability is also a concern flagged in the summary, so buyers should evaluate answer quality on their own material and clarify the contract before proceeding.
What works
- Purpose-built for institutional research and firm knowledge
- Brings documents and financial data together
- Research matrices organize work into rows and columns
What doesn't
- Pricing, seat limits, and usage limits are not published

- OCR makes scans and images searchable
- Indexes local and connected sources
What doesn't
- Listed plans don't match the described product
- Starting price is $100 monthly, billed annually

What works
- Covers AI development, evaluation, intelligence and geospatial work.
- Supports cloud, on-premises, edge and air-gapped deployment.
- Customer-hosted pricing is listed at $7,000 per GPU annually.

03How we chose
We weigh published pricing and plan limits, product documentation, and user sentiment on Reddit. We also consider whether a tool’s stated purpose fits company, research, or broader web search, and how clearly it presents evidence for its answers. When a price, cap, or capability is not published in the published material, we treat it as unknown rather than estimating it. This is a source-based comparison, not a report of hands-on testing, benchmarks, trials, or screenshots.
04Choose by the sources you need searched
Start with where your answers need to come from. For company search, list the internal repositories and work systems your team needs to query, then confirm support in the product’s documentation. For research, decide whether you need scholarly material, citations, or a way to explore connections between papers. For broader questions, clarify whether web search is enough or whether answers must draw on company or specialist sources too.
The tools covered here include Glean, AlphaSense, Elicit, Genspark, Searchable AI, QAnswer, Consensus, Hebbia, Connected Papers, You.com, scite, Felo, Coveo, SciSpace, Dropbox Dash, DeepSearch, Seekr, Fiscal.ai, ScholarAI, and Humata AI. Don’t treat that list as proof that every tool searches the same sources. Check each product’s documentation against your actual source needs before shortlisting.
05Check the real cost before switching
Compare the plan you can actually buy, not a headline starting price. Check whether pricing is public, what each plan includes, and whether the limits that matter to your team are stated. If pricing or a cap is not published, ask the vendor rather than assuming it is unlimited. The published published material for this guide contains no current prices or plan limits, so we won’t quote them here.
Before replacing an existing search workflow, write down the sources people use, the evidence they need to see, and the tasks they expect answers to support. Then verify those points in documentation and vendor terms. Read Reddit feedback as user-reported experience, not a guarantee of results. If a critical requirement is unclear, keep it on your evaluation checklist; don’t make a switch decision on an unverified feature or an attractive price alone.
Questions people ask
Who are the big 5 in AI?
There is no single five-company list that fits every meaning of “big.” The answer changes depending on whether you mean AI research, models, software, or search tools. For this guide, compare products by the sources they search, the evidence they return, and their published pricing—not by an assumed ranking.
Which search engine is best than Google?
There isn’t one best alternative for every search task. If you need answers from company or research sources, assess AI search tools against those specific sources and check how they show supporting evidence. If you mean general web search, define the results and privacy requirements that matter before comparing options.
Is ChatGPT the best AI right now?
“Best” depends on the job, the sources you need, and the evidence you expect to review. This guide covers AI search tools, so compare them on search scope, answer support, documented limits, and price. The available published material does not establish a current overall ranking of AI products.
What is an AI-based search engine?
It is a search tool that uses AI to return answers or insights from sources rather than only presenting a list of links. In this category, the relevant sources may be company or research material. Check product documentation to see which sources a specific tool searches and how it supports its answers.
