Feature Tags Comparison
Key Features
- Ad free approach: Designed results around user intent and citations rather than ad slots or affiliate placements
- Private by design: Focused on data control settings and personal source integrations for unified search
- Generative answers: Produced summarized responses with links to sources to speed research and discovery
- Subscriber model: Explored paid search as a way to fund independent indexing at consumer scale
- Product learnings: Influenced broader adoption of answer engines across the search landscape
- Enterprise pivot: Team and tech moved to serve corporate knowledge search rather than consumer
- Reasoning models: Focused on multistep tasks that need planning consistency and better intermediate reasoning signals
- Structured outputs: JSON mode function calling and extraction endpoints keep responses machine friendly
- Grounding options: Hook models to documents or endpoints to reduce hallucinations and improve trust
- Eval and tracing: Built in tooling to test variants measure quality and observe latency cost and failures
- Controls and guardrails: Safety filters rate limits and sensitive content rules for responsible deployment
- Customization: Fine-tuning and instructions to align outputs with domain style and policy constraints
