Kagi Assistant, a private interface built by the privacy-focused search company Kagi, now offers Anthropic's Claude models alongside 33 other AI systems from 10 providers, letting users switch between models mid-conversation without restarting. The platform includes Claude 4.5 Haiku, Claude 4.6 Sonnet, and Claude 4.8 Opus, with reasoning-enhanced versions of each available at the Ultimate tier.

Why Does Privacy Matter When Choosing an AI Assistant?

The core differentiator for Kagi Assistant is its privacy model. Unlike many AI platforms, Kagi does not use your conversations to train any company's AI models, and it does not share account information with the model providers themselves. This addresses a growing concern among users who want to interact with advanced AI without their data becoming part of future training datasets.

Threads automatically delete after 24 hours of inactivity by default, though users can adjust this setting. Kagi publishes a full LLM (large language model) privacy comparison so users can see exactly how each model handles their data before selecting one. For those handling especially sensitive information, the platform recommends pairing Kagi Assistant with Maple AI, which encrypts messages on your device before they leave it, for tasks like medical or legal consultations.

What AI Models Are Available Through Kagi Assistant?

Kagi Assistant's model roster spans multiple providers and use cases. Beyond Anthropic's Claude family, the platform includes models from Google, OpenAI, DeepSeek, Mistral AI, and several others. The breadth of options allows users to test different models for different tasks without switching between separate applications.

• Anthropic Models: Claude 4.5 Haiku, Claude 4.6 Sonnet, and Claude 4.8 Opus, with reasoning versions available at the Ultimate subscription tier
• Google Models: Gemini 3.5 Flash, Gemini 3.1 Flash Lite, Gemini 2.5 Pro, and Gemini 3.1 Pro
• OpenAI Models: GPT 5.4 Mini, GPT 5.4 Nano, GPT 5.5, and ChatGPT, with GPT 5.5 available only to Ultimate subscribers
• DeepSeek Models: DeepSeek V4 Pro and DeepSeek V4 Flash for different speed and capability tradeoffs
• Mistral AI Models: Mistral Small 3, Mistral Small 4, Mistral Large 3, and Mistral Medium 3.5

Models marked with reasoning capabilities use extended chain-of-thought processing, which means they work through complex logic, math, and multi-step problems more thoroughly than standard models. This makes them particularly useful for coding, research, and technical problem-solving.

How to Switch Between AI Models and Maximize Your Workflow

• Mid-Conversation Switching: You can switch models mid-conversation without starting over, so if one model's answer isn't satisfactory, you can pick another and continue from the same thread
• Use Kagi Quick for Speed: Kagi Quick delivers direct, concise answers in under 5 seconds, ideal for straightforward factual questions and quick research queries
• Use Kagi Research for Depth: Kagi Research provides exhaustive, in-depth analysis in 20+ seconds by running multiple simultaneous searches across different languages, synthesizing findings into sourced answers, and even running Python code or generating images
• Access via Search Bar Shortcuts: Both assistants are accessible from the Kagi Assistant webapp or directly from Kagi's search bar using bangs: !quick or !research

The platform integrates with Kagi's search engine, so any search customizations you have created will be honored when the assistant pulls information. This means if you have already configured Kagi Search to prioritize certain sources or exclude others, those preferences carry over to your AI interactions.

What Are the Pricing Tiers and Token Allowances?

Kagi Assistant uses a value-based usage system where your monthly plan determines your token allowance. A token is roughly equivalent to a word or small piece of text, so the allowances translate to how much you can interact with the AI and run searches.

The Starter plan costs $5 per month and includes 300 searches plus AI interactions, with access limited to standard models only. The Ultimate plan costs $25 per month and provides unlimited searches plus AI interactions, with access to all models including premium ones like Claude Opus, GPT 5.5, and the more advanced Kagi Research assistant. For users who primarily need quick answers and basic coding help, the Starter tier may be sufficient, while those running complex research projects or needing access to the most capable models will benefit from the Ultimate tier.

The inclusion of Claude across both tiers reflects Anthropic's position as a major player in the AI assistant market. Claude's availability at multiple capability levels, from the lightweight Haiku to the reasoning-enhanced Opus, gives users flexibility to choose the right model for their task and budget constraints.
