Lucidspark
6.4Lucid Software's whiteboard with the Lucid AI assistant, breakout boards and tight Lucidchart integration
Lucidspark is the whiteboard product from Lucid Software (makers of Lucidchart) — an infinite canvas with sticky notes, voting, timer, breakout boards, the Lucid AI conversational assistant (prompt-to-board, clustering, summaries), and bidirectional sync with Lucidchart for diagrams. Strong enterprise posture inherited from Lucid: SSO/SAML, SCIM, SOC 2 Type 2, ISO 27001/27701, FedRAMP, GDPR, and US/EU/AU data residency.

Lucidspark — pros
- + Tight integration with Lucidchart — switch between diagram and whiteboard on the same canvas
- + Breakout Boards let you split a workshop or retro into parallel rooms
- + Strong enterprise posture: SOC 2 Type 2, ISO 27001/27701, FedRAMP, GDPR, SSO/SAML, SCIM, US/EU/AU data residency
- + Generous integration set: Jira, Slack, Teams, Confluence, Azure DevOps, Asana
- + Free tier exists and is enough to evaluate the tool
Lucidspark — cons
- − No native anonymous voting — names always visible on stickies
- − No health checks, recurring retros, action carryover or cross-team rollup
- − AI is general brainstorming/clustering, not retro-aware — no sentiment, action-item extraction or trend insight across retros
- − Free tier is restrictive: 3 boards and 100 shapes/board limits real use beyond evaluation
- − Brand is best known for diagramming; retro template depth trails Miro and Mural
Retrium — pros
- + Battle-tested five-phase guided facilitation flow
- + Anonymous brainstorming and grouping by design
- + Persistent team-room action plan that carries forward between retros
- + Team Radar covers psychological safety and custom health checks
- + Per-team-room pricing with unlimited users on every plan
Retrium — cons
- − No free tier; 30-day trial only
- − Integrations are thin beyond Jira Cloud and a <em>still-beta</em> Slack app
- − <strong>No AI features at all</strong> — no summary, clustering, action-item extraction or insights
- − No native Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence integration
- − Public shipping cadence has slowed — no 2025 changelog or product blog activity visible
- − Retro-only scope; no planning poker, kudos, icebreakers or whiteboard
