Install the extension and Continuity auto-detects whichever supported AI tools you already use — Claude Desktop, Claude Code, Cursor, Cline / Roo Code, GitHub Copilot, Google Gemini, and any MCP-compatible tool. It configures MCP automatically. No manual config files, no JSON editing.

Open any existing codebase and the Initial Project Scanner reads your files and creates draft decisions automatically. First-run git seeding pre-populates decisions from your recent commit history. You start with a foundation — not a blank slate.

Your trial gives you unlimited decisions and every Pro feature: semantic search, Dream Engine, Knowledge Graph, code intelligence, and the full MCP tool set available to your profile. Test the entire workflow before committing. After the trial, keep read/search access and log up to 10 decisions lifetime (15 with email verification), or upgrade for $9/month.

Continuity runs 5 automated detection layers with 19 detection points — file system monitoring, git hooks, MCP middleware interception, conversation analysis, and enhanced prompts. Important architectural choices are captured even when you forget to log them manually.

Synthetic memory persists across every session. O(1) constant-time lookups mean your AI has full context in seconds — even with hundreds of decisions accumulated over months.

Code intelligence links decisions to specific files and functions. When you change something significant, your AI checks refactoring safety automatically — it knows what assumptions exist in the code and warns you what might break.

Clone a repo and the Project Scanner reads the structure and git history to generate draft decisions automatically. Your AI understands the codebase's architecture before you've written a single line.

Decisions are stored as plain JSON in `.continuity/` — fully git-committable. Everyone on the team gets the same context. A new hire clones the repo and their AI already knows every architectural choice the team has made.

The Knowledge Graph holds up to 1,500 nodes and renders in force-directed, radial, tree, or DAG layouts. See how decisions relate to each other, which ones were superseded, and how your architecture evolved — all in one interactive view.

New hires skip weeks of reading stale wiki docs. The team's full decision history — complete with reasoning and lifecycle status (active, draft, outdated, superseded) — loads into the AI automatically. Teams save significantly on token costs vs. traditional documentation approaches.

Export Architecture Decision Records (ADRs) directly from your logged decisions. Compliance-ready docs from your actual architectural history — not manually maintained wikis that go stale.

Current benchmark: 1,360 decisions total. Embedding that history in CLAUDE.md would cost 311,752 tokens, while a Continuity search session comes in at 15,476 tokens across three queries. That is 95% savings and 20.1x efficiency, with the embedded approach hitting the 200K context wall around 864 decisions.

Continuity exposes MCP tools in profiles instead of a brittle fixed count. The current tool set is grouped into core, standard, and full profiles, with support across Claude Desktop, Claude Code, Cursor, Cline / Roo Code, GitHub Copilot, Google Gemini, and other MCP-compatible tools.

The Dream Engine runs a 4-phase memory consolidation cycle — like sleep for your project's memory. It identifies redundant decisions, resolves conflicts, promotes draft decisions, marks outdated ones, and strengthens connections in the Knowledge Graph.

Pro's hybrid search combines keyword matching with embedding-based semantic search. Ask "why did we avoid using a monorepo?" and get relevant decisions even if they never use those exact words.
