What LLM Stats actually measures
These are real conservative TrueSkill index scores from the LLM Stats backend—not consumer-product test scores. Each mapping uses a representative vendor model and never claims that the consumer app routed to it.

Scores are not percentages
Each value is the category's conservative score μ − 3σ. Compare ranks within a column; do not average scores across categories.
Missing means missing
“Not measured” is never converted to zero. The games count is visible because sparse results carry more uncertainty.
Product gaps stay explicit
Memory, voice UX, native image creation, citation entailment, and recovery lack comparable product runs and are not scored.

Product reviews
Eight chatbots, eight explicit verdicts
#1 · Best overall
ChatGPT
The most complete consumer AI product: excellent general answers, deep research, files, voice, images, memory, and a mature tool ecosystem in one interface.
Where it wins
- Broadest all-round toolset
- Strong multimodal workflow
- Polished apps and custom GPTs
Know before choosing
- Best models and tools have usage limits
- Citations are less central than in research-first products
Free: Yes — core chat, search, voice, files, and image tools with limits
Paid: Plus $20/month; Pro $200/month
Evidence record
- Sources checked
- Model mapping
- GPT-5.6 Sol
Model indexes cover general capability, search, code, long context, vision, and tool calling. Product memory, voice, citation accuracy, and recovery are not measured comparably.

#2 · Writing and coding
Claude
The best choice for thoughtful prose, document work, and sustained collaboration. Its clean answers and strong coding tools make it especially good for focused knowledge work.
Where it wins
- Natural, controlled writing
- Excellent long-document work
- Strong coding and artifact creation
Know before choosing
- No native image generation
- Usage ceilings can interrupt long sessions
Free: Yes — chat, web search, files, memory, code execution, and connectors with limits
Paid: Pro $20/month or $17/month billed annually
Evidence record
- Sources checked
- Model mapping
- Claude Opus 4.8
The selected model has general, search, code, long-context, vision, and tool-calling evidence. It has no communication-index observation in this snapshot, so writing remains not measured for this model.

#3 · Best free plan
Gemini
The strongest free package for most people, with capable models, Deep Research, Gemini Live, image creation, and unusually useful connections to Google services.
Where it wins
- Generous multimodal free tier
- Google Search grounding
- Gmail, Drive, and Workspace context
Know before choosing
- Feature availability varies by account and region
- Product naming and limits change frequently
Free: Yes — chat, Deep Research, Gemini Live, images, Canvas, and Gems with limits
Paid: Google AI Pro $19.99/month
Evidence record

· Official no-subscription limits, model availability, features, and privacy documentation rechecked.
#4 · Research and citations
Perplexity
The fastest path from a question to a source-backed answer. Choose it when web discovery, citation inspection, and follow-up research matter more than creative conversation.
Where it wins
- Best citation-first interface
- Fast web synthesis
- Choice of advanced models on paid plans
Know before choosing
- Less natural for open-ended creative work
- Source quality still needs human checking
Free: Yes — standard search, limited Pro Search, Research, and file uploads
Paid: Pro from $20/month
Evidence record
- Sources checked
- Model mapping
- None—multi-model routing
Perplexity routes across multiple models. Assigning one LLM Stats model or index score to the consumer product would be misleading, so model evidence is intentionally not mapped.
Model indexes and source history +
No honest single-model index mapping is available.
· Official search, citation, file, model-routing, pricing, and data-control documentation rechecked.
#5 · Microsoft 365 users
Microsoft Copilot
The practical pick when your work already lives in Word, Excel, PowerPoint, Outlook, Edge, and Windows. The standalone chatbot is useful; the real advantage is integration.
Where it wins
- Deep Microsoft ecosystem fit
- Useful free web answers
- Strong office-document workflows
Know before choosing
- Product tiers and identities are confusing
- Best integrations require Microsoft 365
Free: Yes — web-grounded chat, writing help, voice, and image creation
Paid: Microsoft 365 Personal from $9.99/month or $99.99/year
Evidence record
- Sources checked
- Model mapping
- MAI-Thinking-1
The snapshot contains general, communication, code, long-context, vision, and tool-calling evidence. It does not measure Microsoft 365 integration quality.

· Official free-versus-Microsoft-365 feature boundaries and consumer privacy documentation rechecked.
#6 · Real-time X and web context
Grok
A fast, capable assistant with unusually direct access to live web and X context, plus strong voice and media creation. Best for trend-aware exploration, with extra care around source quality.
Where it wins
- Real-time web and X search
- Direct conversational style
- Image and video creation
Know before choosing
- Live social sources can amplify weak information
- Frontier access costs more than most rivals
Free: Yes — real-time search, voice, connectors, and limited usage
Paid: SuperGrok $30/month
Evidence record
- Sources checked
- Model mapping
- Grok 4.6
The snapshot contains general, code, and tool-calling evidence. Search, communication, long-context, and vision indexes are missing for this exact selected model.

· Official Grok 4.6 access, free limits, voice, files, connectors, generation, pricing, and privacy documentation rechecked.
#7 · Free reasoning
DeepSeek
Exceptional model capability for a free product, especially for reasoning and technical questions. The consumer app is much thinner than the leading all-in-one assistants.
Where it wins
- High capability at no subscription cost
- Clear reasoning mode
- Useful file text extraction
Know before choosing
- Few consumer integrations
- Not our privacy pick for sensitive material
Free: Yes — no subscription; chat, reasoning mode, web search, and file extraction
Paid: No consumer subscription
Evidence record
- Sources checked
- Model mapping
- DeepSeek V4 Pro
The snapshot contains general, code, vision, and tool-calling evidence. Consumer memory, voice, images, and citation accuracy are not benchmarked.
Model indexes and source history +
Representative recent DeepSeek model in LLM Stats; the official consumer-app page does not establish identical routing.

· Official consumer-app search, file extraction, free access, and privacy documentation rechecked.
#8 · Casual chat and social apps
Meta AI
The easiest assistant to use without changing habits because it is embedded across Meta’s apps. Great for casual questions, voice, and playful images; weaker for rigorous knowledge work.
Where it wins
- Available inside familiar social apps
- Good voice and image creation
- No subscription needed
Know before choosing
- Limited professional workflow tooling
- Citations and file work are not core strengths
Free: Yes — consumer chat and creative tools are free
Paid: No consumer subscription
Evidence record

- Muse Spark 1.1
The snapshot contains general, code, vision, and tool-calling evidence. Muse Image and the consumer voice experience are documented features but are not scored by these text-model indexes.

Independent methodology
How we map the evidence
Model measurements and product documentation answer different questions. We publish both, keep them separate, and state what neither can prove. We do not publish hands-on product scores without saved, auditable runs.
Product features and US list prices were last rechecked on Aug 27, 2026. The index snapshot carries its own retrieval timestamp. We accept no affiliate commission for placement.

Coverage gap
Not measured
Product memory, voice UX, image creation, citation entailment, and recovery need recorded cross-product runs before scoring.
Privacy verdict
There is no universal “most private” free chatbot. Consumer settings, retention, training choices, and regional rules differ. For confidential work, use a business or enterprise plan that contractually excludes training, configure retention, and follow your organization’s data policy.
Limitations
Plans and model routing change quickly. Representative models do not prove consumer-app routing, model indexes do not measure product UX, and documented feature availability does not prove quality. A source link is not proof that a generated claim is correct—open the source.
The technology underneath
Chat model benchmark ranking
Model scores inform our product verdicts, but they are not the verdict. Consumer products also differ in search, tools, memory, voice, files, limits, and privacy controls.
