Astell Reviews & Product Details

Astell is the AI memory layer for fast-scaling teams. It connects to Slack, Gmail, Google Calendar, Google Drive, Notion, Linear, and GitHub and unifies what lives in them, every message, email, meeting, document, ticket, and commit, into one permission-aware memory of your company: who decided what, who owns it, and what happened next. Every answer cites its source. Teams use Astell to retrieve any answer with its source, to automate the follow-through (an email, a Slack post, a calendar event, a Linear or GitHub issue, each confirmed before it goes out), and as a proactive second brain: Loops are agents that sort your signals, data, and knowledge with deterministic heuristics and best-practice inference and track every decision, promise, and request until it lands. Model-agnostic (Anthropic, OpenAI, and other frontier models), cited so accuracy can be checked, and available to Claude, ChatGPT, and any MCP client. Free plan. Team plans from $20 per seat per month billed annually.
