Krater is an AI workspace that aggregates models under one subscription. Users chat with more than 400 models, including ChatGPT, Claude, Gemini, Grok, Mistral and DeepSeek, generate, edit and upscale images and video, generate and debug code with live previews, use text-to-speech, transcription and voice changing, and run web research whose findings are saved to a Keep library. It connects to more than 300 apps such as Gmail, Slack, Notion and GitHub, runs scheduled agent tasks, and builds documents, slides and websites from prompts.
The proposition is consolidation: one login and one bill in place of several model subscriptions, plus a layer of integrations and automation on top. The trade-off is that a credit system sits between you and every model, and the pages reviewed do not explain what a credit buys, so the effective cost per task is hard to compare with paying providers directly. The site reports more than 100,000 users, a 4.8 rating and a strip of employer logos whose staff use it; those are self-reported and do not mean company-wide adoption. The operator is listed as Krater.ai Ltd, said to date from 2022.
Plans are billed yearly: Pro at $200 a year with 1,500 credits a month, Ultra at $490 a year with 4,000 credits a month, Max at $1,190 a year and a custom Enterprise tier, and no free plan is mentioned. Test whether your regular workloads fit inside the monthly credit allowance before committing to an annual payment.
