Fastio
Shared workspace connecting cloud drives to AI agents, benchmarked against Dropbox.
Fastio is a project workspace that syncs files in from Google Drive, Dropbox, Box or OneDrive and gives every AI agent on the project — Claude, ChatGPT, Gemini, Cursor or any MCP agent — the same access as the team. In its own published benchmark, run on a 2,163-file contract-review corpus with Claude Opus 5, the same agent answered 74% faster, made 95% fewer tool calls, and cost 81% less working through Fastio than through Dropbox alone. Access is scoped to the project workspace rather than individual accounts, so files don't leak into someone's personal drive when they leave.
What holds up
- +Published benchmark: 74% faster answers and 95% fewer tool calls than Dropbox alone
- +No migration — syncs only the files you need from Drive, Dropbox, Box or OneDrive
- +Access follows the project workspace, not personal accounts, when people leave
Mind the limits
- −Benchmark numbers come from Fastio's own three-run test, not an independent source
- −No pricing shown beyond a 14-day trial — you have to ask to find the cost
