Frequently asked questions
Quick answers about capsules, the MCP server, supported clients, data storage, and pricing.
What is dropdat?
A browser extension and MCP server that captures any AI conversation as a portable capsule. Drop the capsule into another AI to resume the chat; recall it from any MCP-capable coding agent over a tool surface.
What is a capsule?
A structured snapshot of an AI conversation: every message, role, timestamp, plus tags and a title. Capsules have version history (rootId + parentId chain) so you can fork, edit, and trace lineage.
Which AI providers does the extension support?
ChatGPT, Claude, Gemini, Grok, Copilot, and Perplexity. Capture works via per-provider content scripts that read the on-page DOM directly.
Which MCP clients can use dropdat?
Anything that speaks the standard MCP stdio transport: Claude Code, Cursor, Cline, Claude Desktop, Continue, plus any custom client.
How do I install the MCP server?
`npx -y @dropdat/mcp` runs the latest version on demand, or `npm install -g @dropdat/mcp` pins it. Configure your client with the DROPDAT_API_KEY env var.
Is it free?
Yes for personal use. The extension, MCP server, and a dropdat account are free. The MCP source lives at github.com/dropdat/mcp under MIT.
Where is my data stored?
In your dropdat library — Postgres + pgvector. Capsules are local-first via IndexedDB and sync to the server in the background. Export anytime.
How does semantic recall work?
Capsules are embedded with OpenAI on save. Queries embed and run against pgvector cosine similarity, then fuse with BM25 keyword ranking via Reciprocal Rank Fusion.
Can I self-host?
The MCP server is open source. The API/backend is currently hosted at dropdat.app; self-host instructions will be published as the API stabilises.
How do I cancel my plan?
Open Billing in the dashboard and hit Cancel plan. The cancellation takes effect at the end of your current billing period — you keep access until then.
Do you offer refunds?
Yes — we refund any plan as long as you haven't used a paid feature after purchase. Contact support from the dashboard with your account email and we'll process it.
