Context Engine

Context Engine is a hosted memory service for teams that use several AI tools. Claude, ChatGPT, Cursor and other tools save decisions, notes, people, customers and files into it as they work and read from it when a session starts. People on the team can read the same memory in the app, ask it questions in plain words and add files. It is made for individuals, consultants who keep one memory per client, and whole teams, so that nobody has to explain the same thing twice.

Memory is organised into engines, each with a stated purpose. A connection reaches only the engines you choose, and a search across engines names where each result came from. Every change records who made it and with which tool, summaries are written for each day, and duplicates are caught. Memories are searched by meaning as well as exact words, and everything can be exported as Markdown at any time. ChatGPT, Claude, Claude Code and Cursor are listed as supported tools, and anything that speaks MCP can connect too.

Pricing is per engine rather than per person, and people are free on every plan. Free costs $0 and allows 1 agent per engine, plus 1 for each referred friend up to 3, with 1 GB of memory. Pro is $12 a month or $99 a year per engine with 10 agents and 25 GB. Unlimited is $39 a month or $299 a year per engine with 100 GB. Enterprise runs on your own server from $6,000 a year per install, with updates and support included.

Before buying, note that prices are in US dollars, before VAT or sales tax, and payment is by card. Each connected app, personal key or engine key counts as one agent, so plan limits depend on how many tools you connect to an engine. When an engine is full, new memories are refused until you archive content or move to a bigger plan. Confirm rupee billing and invoicing terms with the vendor before buying for an Indian company.
