Calk - 2026 Pricing, Features, Reviews & Alternatives

Calk is a no-code AI agent builder platform that allows teams to create internal AI agents powered by their own data and tools. It assists with internal knowledge management, AI productivity, and workplace automation. Designed for modern, often remote-first teams, Calk helps operational, sales, marketing, and customer support teams deploy AI agents tailored to their workflows.

The platform connects with popular workplace tools such as Notion, Slack, Hubspot, Google Drive, Intercom, and Jira. By syncing these sources, Calk allows users to centralize knowledge from various systems and use it to train AI agents that can answer internal questions, automate support tasks, or assist with sales documentation. Users can connect data sources, import content, and assign that knowledge to specific AI agents. These agents can be customized with tone, scope, and instructions, allowing teams to create role-specific agents such as onboarding guides, product documentation bots, or deal prep assistants for sales teams.

It offers integration with multiple data sources such as CRM, documentation tools, and communication platforms. Calk extends support for multi-model AI use, including OpenAI (GPT-4o), Claude, Mistral, and others. Key features include the ability to tag up to four models or agents at once to compare outputs and performance, real-time syncing from tools such as Notion to keep agent knowledge fresh.

Calk provides use-case-specific agent creation, including internal support, sales prep, and FAQ response. It is primarily used by SaaS businesses, growing startups, and remote or asynchronous teams who rely on strong documentation and internal knowledge sharing. It helps manage repetitive internal questions, optimize knowledge accessibility, and support faster onboarding and decision-making. The platform is adaptable across team functions and encourages a modular approach to AI use — where each AI agent is assigned to a specific task or process.
