FAQ
How is ACE different from ChatGPT's built-in memory?
ChatGPT memory is limited, unstructured, and shared across all conversations. ACE gives your AI coding assistant structured memory types (ADRs, error history, code patterns), a knowledge graph for discovering related context, and namespace isolation per project. Plus your data stays on your own database.
Will this slow down my AI responses?
No. ACE runs locally with sub-10ms lookups. Your AI retrieves context instantly without adding latency to your workflow.
Where is my data stored?
Your codebase memory stays on your PostgreSQL database - complete privacy. Use Neon (free tier available), AWS RDS, Google Cloud SQL, Azure, Supabase, or local PostgreSQL.
What happens during the 14-day trial?
You get full Pro access for 14 days - no credit card required. All features, unlimited memories, unlimited namespaces. After 14 days, you'll have 7 days to add a payment method before access is paused.
What if I don't add payment during the trial?
Your data is never deleted. After the trial (14 days) and grace period (7 days), your access is paused until you add a payment method. Once you subscribe, all your data is immediately accessible again.
When should I upgrade to Pro?
Upgrade to Pro when your dev team needs shared AI context (everyone's AI learns from shared memories), unlimited memories, or more than 3 namespaces. Pro is designed for teams with 10 developers included.
What is the MCP Server?
MCP (Model Context Protocol) lets AI coding assistants call ACE memory functions natively. Your AI calls ace_remember, ace_track_issue, ace_recall directly. Works with Claude Code, Codex CLI, Gemini CLI, Cursor, Windsurf, and ChatGPT.
What memory types does ACE support?
ACE supports 10 memory types designed for codebases: Error History (debug context that persists), ADRs (architecture decisions your AI follows), Session Context (pick up where you left off), Architecture, Coding Standards (rules your AI applies), Code Patterns (solutions your AI remembers), Tags, Relationships, and Generic Memories.
How does the knowledge graph work?
The knowledge graph connects memories using 12 relationship types. Your AI traverses the graph to discover context automatically - like tracing an error back to the architectural decision that caused it, then finding the fix.
Can I use ACE with Copilot?
Yes. GitHub Copilot doesn't support MCP yet, but ACE provides a REST API (210+ endpoints) that any AI tool can use. Your Copilot workflow can query ACE for context.
Can I upgrade or downgrade?
Yes. Upgrade anytime and changes take effect immediately. Downgrade at the end of your billing period. Your data is always preserved.
How do extra users work on Pro?
Pro includes 10 developers for £39.99/month. When one developer's AI learns something, everyone's AI knows it. Need more? Add extra users at £3/user/month.
Do I need to set up my database?
No. Just connect an empty PostgreSQL database and ACE creates all the tables automatically. Nothing to configure.
