Pieces

by Pieces

Pros

• ✓Every generated answer carries inline citations to the customer's own sources, and it is designed to say it does not know when those sources do not cover a question.
• ✓One knowledge base serves the Retrieval API, a hosted MCP server and pre-built agents for a website widget, Slack, Discord, a support form, Zendesk and in-product use.
• ✓Ingests more than 20 source types, from documentation sites, GitHub and OpenAPI specs to Zendesk tickets, Confluence and Notion, with continuous sync on paid plans.

Limitations

• –Growth and Enterprise are quote-only, commercial plans carry a minimum annual commitment, and there is no self-serve card signup.
• –Private sources, continuous sync, zero data retention and PII masking start on Growth, and SSO, SCIM, role-based access control and EU hosting are Enterprise features.
• –The hosted MCP search tool returns results in about 3 seconds at the median and 4.5 seconds at the 95th percentile, and public OAuth servers allow 600 searches per user per day.

Pros

• ✓Captures context automatically from email, chat, meetings, browsers and developer tools, so standups, recaps and meeting prep come from what actually happened rather than manual notes.
• ✓One-click MCP connections carry the same memory to Claude, Cursor, GitHub Copilot, Codex and more than a dozen other clients, with unlimited MCP use on Pro.
• ✓Memories are stored on the device by default, capture can be limited by app and website, and the company states it never trains its models on customer content.

Limitations

• –There is no free plan: the 7-day trial requires a card, and continued use costs $18.99 per user per month on Pro or $169.99 per year.
• –Shared team memory is still on the roadmap, so Enterprise today adds governance and provider controls rather than pooled context across people.
• –Capture runs continuously from the focused app, the clipboard and meeting audio, so teams need to set app and website exclusions before a wider rollout.
