Krater

Krater is an all-in-one artificial intelligence workspace designed to aggregate hundreds of models, including ChatGPT, Claude, Gemini, and Grok, into a single subscription. It takes the form of a unified application where users can switch between different AI models mid-chat without leaving the interface. The platform aims to eliminate the need to juggle multiple separate subscriptions and tool interfaces by combining text, code, image, video, and audio generation into one environment.

• Access to over 350 AI models including ChatGPT, Claude, Gemini, and Grok
• Agent capability that plans, researches, browses the web, runs tools, and executes tasks based on user goals
• Code generation, debugging, and execution with live previews
• Image generation supporting models such as Nano Banana Pro, Grok Imagine, Flux, and Ideogram
• Video generation supporting Kling, Seedance, Sora, and HeyGen
• Audio generation and transcription using ElevenLabs and OpenAI voices
• Integration capabilities with external applications including Gmail, Slack, Notion, and GitHub
• Natively available interface in 12 languages

Pros

• Consolidates access to hundreds of different AI models under a single subscription to prevent tool-juggling
• Provides built-in web browsing and autonomous agent capabilities to execute multi-step workflows from a single prompt
• Supports a wide variety of content types including text, code, images, video, and audio within one workspace
• Offers privacy protections with EU-hosting, GDPR compliance, and a stated policy against selling or training on user data

Cons

• Pricing tiers rely on monthly credit allocations, meaning heavy usage may require credit top-ups or higher plans
• Website publishing limits vary by tier, ranging from one website on the Pro plan up to five on the Max plan
• Context window lengths differ significantly between tiers, spanning from 128k on Pro to 1M on Max
• Storage limits apply to the Keep storage feature, capping at 25 GB on Pro, 100 GB on Ultra, and 250 GB on Max

Krater fits creators, developers, entrepreneurs, and teams looking to consolidate multiple AI subscriptions and streamline content creation, coding, and research workflows into a single interface. It is a poor fit for users who rely exclusively on a single AI provider without needing cross-model comparisons, or those who require completely free, unlimited access without tiered credit caps.

Krater is offered on a recurring subscription model with monthly and yearly billing options. The Pro tier is priced at $200 per year or a monthly equivalent, providing 1,500 credits per month, a 128k context window, 25 GB Keep storage, and the ability to publish one website. The Ultra tier is priced at $490 per year or a monthly equivalent, offering 4,000 credits per month, a 200k context window, 100 GB Keep storage, auto routers, and two website publishes. The Max tier costs $1190 per year or a monthly equivalent, providing 1 million context window, 250 GB Keep storage, team collaboration, and five website publishes. An Enterprise tier is available with custom volume and prepay discounts, unlimited team seats, SSO, SAML, SCIM provisioning, and custom model allow-lists through sales contact.

Unlike using individual subscriptions for tools like ChatGPT or Claude separately, Krater aggregates over 350 models into one home and lets users switch between them mid-chat. It pairs this multi-model access with autonomous agents that browse the web and run tools, alongside direct connections to third-party applications like Slack and GitHub. The platform positions itself as a single hub to eliminate context switching and tool fatigue.

Krater integrates with Gmail, Slack, Notion, and GitHub, alongside file formats and models such as ChatGPT, Claude, Gemini, Grok, Nano Banana Pro, Flux, Ideogram, Kling, Seedance, Sora, HeyGen, and ElevenLabs.
