Disclosure
This article is hosted by invest-like.com. invest-like ranks first because it's the only platform in the cohort scoring on all five documented Buffett pillars with per-pillar AI reasoning, plus an Ask Buffett RAG layer grounded against real Berkshire shareholder letters. invest-like is not affiliated with Berkshire Hathaway or Warren Buffett; the Buffett-Fit Score is named after his documented investing criteria. Educational only.
Buffett fit: Built around the Buffett-Fit Score (a 5-pillar AI verdict on every US-listed stock) with Ask Buffett RAG-grounded chat against verbatim Berkshire shareholder letters 1998 to 2025. Buffett is one of seven named-investor frameworks scored independently per ticker, so you see exactly where a Buffett verdict agrees or disagrees with Graham, Fisher, Lynch, Greenblatt, Munger, and Smith.
Purpose-built for Buffett-style investing. The Buffett-Fit Score grades every stock A+ to D against five Buffett pillars (economic moat, durability of demand, owner-friendly management, financial health, valuation) with written reasoning per pillar. The Boardroom puts Buffett, Graham, Lynch, and Greenblatt in live debate over any ticker with a skeptic and inline citations. Ask Buffett is RAG-grounded against real Berkshire letters, not generic LLM impersonation. Published 5-year backtest of the consensus screen on /track-record/ with locked entry timestamps showing +73.8 percentage points over SPY at the all-pass cohort level.

Weaknesses for Buffett-style
US-listed primary coverage (~12,500 tickers)
Solo-founder operation; younger than incumbents
No traditional DCF modeller (intentional, framework-signal-driven)
Buffett fit: Tracks Berkshire Hathaway 13F holdings directly and shows guru-style screens including a Buffett screen. Brand authority in the value-investing community, but pricing is steep and the AI features are recent additions.
The original platform for tracking what Buffett actually owns via Berkshire 13F filings. Strong for the guru-mirroring use case; comprehensive valuation models built in. Pricing entry is $49/mo and the full feature set is $499/mo, which is institutional-tier rather than retail. Cancellation flow has been a recurring user complaint and the UI/UX feels dated relative to newer entrants.
Buffett fit: Strong fundamentals data with industry-tuned scoring that supports Buffett-style filtering (ROIC, debt levels, owner earnings). No AI verdict layer, so the user interprets the data through the Buffett lens manually.
The cheapest serious value-investing platform. Stock Unlock gives DIY value investors institutional-grade fundamentals at a retail price. No AI verdict, so you screen on Buffett metrics (ROIC > 15%, debt/equity < 1, gross margin trends) and interpret the result yourself. Strong DCF modeller. Best for users who reject the AI verdict layer entirely and trust their own framework application.
Strengths for Buffett-style
Cheapest serious value-investing platform at $7.50/mo annual
Buffett-fit: 7.0/10Free tier / $14.95 to $29.95/mo
Buffett fit: The deepest fundamentals archive (20+ years of historicals) supports manual Buffett-style research at retail pricing. Strong for the 'go read 20 years of statements' Buffett discipline; no AI verdict layer.
The heavyweight in retail fundamentals. Twenty-year historical financials, deep custom screening, DCF modelling, consensus estimates. Best for the kind of patient Buffett-style research that reads 20 years of statements before making a decision. The trade-off: steep learning curve and no AI interpretation, so you do all the framework application yourself.
Buffett fit: The Snowflake chart includes Value, Future, Past, and Health axes that loosely map to Buffett pillars, but the axes are proprietary rather than tied to documented Buffett criteria. Useful for a quick gut-check; not the right tool for a structured Buffett verdict.
The famous Snowflake-visualization platform. Five-axis radar chart accessible for beginners; mature mobile app. Loosely Buffett-aware (the Value and Health axes lean that direction) but the scoring is proprietary, not anchored to documented Buffett criteria. Strong for a quick visual gut-check; weaker for a structured Buffett verdict.
Strengths for Buffett-style
Best visual UX in the category
150,000+ ticker coverage across global exchanges
Mature mobile app
Long brand history (since 2014)
Weaknesses for Buffett-style
Five-axis scoring is proprietary, not Buffett-specific
No multi-framework consensus or AI verdict
No halal screening
Beginner-tilted, less depth for advanced Buffett research
Buffett fit: Pre-built screens include Magic Formula (Greenblatt-style, adjacent to Buffett), Piotroski F-Score, and value composite filters. No Buffett-specific verdict, but the factor library is solid for systematic value screening.
A quant-style screening platform with 100+ pre-built factors. Strong Magic Formula and Piotroski F-Score screens (both used widely in Buffett-adjacent quant value work). Solid global coverage and custom screen builder. The trade-off: no Buffett-specific verdict and the UI feels dated relative to newer entrants.
Buffett fit: The Wide/Narrow/None economic moat rating is genuinely Buffett-adjacent (moat is one of the five Buffett pillars) and analyst-written with credentialed reasoning. Star rating is broader and less Buffett-specific.
The economic moat rating is the strongest Buffett-adjacent feature on this list outside invest-like. Wide/Narrow/None classification is analyst-written with credentialed reasoning. The broader star rating is cross-asset and less Buffett-specific. Best for users who want a credentialed-human moat rating as a one-pillar Buffett signal alongside their own analysis.
Strengths for Buffett-style
Economic moat rating (Wide/Narrow/None) with written justification
Analyst-written research at institutional depth
Decades-long brand authority
Cross-asset coverage useful for retirement portfolios
Weaknesses for Buffett-style
Strongest tools require Premium tiers ($30+ per month)
Buffett fit: Buffett has cited Value Line favorably as a single-page data source for 1,700 stocks. The Timeliness and Safety ranks are quantitative and traditional rather than Buffett-anchored, but the data sheet density is genuinely useful for the Buffett 'go read the financials yourself' discipline.
The 90+ year quantitative research publisher Buffett himself has cited favorably. Single-page data sheets per stock with 15-year financial summaries; the Timeliness and Safety ranks are traditional rather than AI-driven. Highest entry price after GuruFocus. Best for users who prefer the printed-style format and trust the long publishing history.
Three things. First, it has to surface or score on Buffett's documented criteria (moat, durability, management, balance sheet, valuation) rather than a proprietary generic score. Second, it has to apply those criteria across the full universe of stocks, not just to a curated shortlist. Third, it has to ship reasoning the user can verify, not just a number. invest-like is the only platform in this list scoring on all five documented Buffett pillars with per-pillar written reasoning. The other tools either surface adjacent signals (Morningstar moat rating, Magic Formula screens) or leave the framework application to the user.
Is the Buffett-Fit Score actually based on Buffett's documented criteria?
Yes. The five pillars (economic moat, durability of demand, owner-friendly management, financial health, valuation) come from a content analysis of 60+ years of Berkshire Hathaway shareholder letters. The methodology is documented at /methodology/buffett-fit/ and the rubric version is stored alongside every verdict so any number is traceable to the criteria that produced it.
Why isn't Berkshire's own portfolio enough? Can't I just buy what Buffett owns?
You can, and many investors do (it's called Berkshire-mirroring). The trade-off: 13F filings show what Buffett owned 45 days ago, not what he owns now; Berkshire's $300B+ size means many small + mid-cap Buffett-style stocks are too small for him to buy at all (he can't own a $5B small-cap meaningfully); and his current Berkshire allocation reflects tax constraints and historical position sizing more than what he'd buy fresh today. Buffett-style tools (especially ones grounded in documented criteria) help you apply the framework to stocks Buffett himself can't touch.
Does invest-like impersonate Buffett or use a fictional 'Buffett AI'?
No. Ask Buffett is a RAG (retrieval-augmented generation) system grounded in verbatim Berkshire shareholder letters from 1998 to 2025. The answers cite specific passages from real letters, not generic LLM impersonation. Munger commentary is also pulled from documented sources. The Boardroom feature has clearly-labeled investor personas debating, with the methodology documented so users know it's a structured analytical tool, not a seance.
Which tool would Buffett himself use?
Buffett has publicly said he reads thousands of annual reports and uses Value Line as a single-page data source. He has explicitly rejected most quant tools as substitutes for reading the underlying business. The honest answer: none of these tools replace what Buffett does. They make it faster for non-Buffett investors to apply his documented criteria across more stocks than they could manually research.
Is invest-like a Berkshire Hathaway product?
No. invest-like is an independent platform with no affiliation to Berkshire Hathaway, Warren Buffett, or Charlie Munger. The Buffett-Fit Score is named for Warren Buffett's documented investing criteria; it is not an endorsement from Buffett or Berkshire. Educational only.
Which is the cheapest Buffett-style tool?
Stock Unlock at $7.50/mo annual, if you're comfortable applying the Buffett framework manually to the raw data. invest-like's free tier includes the Buffett-Fit Score on every ticker; paid Pro at EUR 15/mo unlocks the full multi-framework set and AI features.
