Alternatives to PlexeAI

Abacus.AI markets an "AI Agent" platform (ChatLLM, priced from $10/month) alongside an Enterprise tier, positioned for professionals and larger organizations. The agent supports browser use, coding, data analysis, trading, research, chatbots, and video/audio generation, and can coordinate multi-agent "Agent Swarm" workflows for complex multi-part builds such as full CRM platforms. It connects to third-party tools (Gmail, Drive, Slack, Twitter, YouTube, GitHub) and MCP servers, and gives users access to 100+ interchangeable third-party AI models (e.g. Opus 5, Fable 5, GPT-5.6 Sol, Gemini 3.1 Pro) rather than a single proprietary model. The Enterprise offering advertises security and permissions controls, and some example workflows include logging outputs to CSV or flagging uncertain cases for manual review.
