Pros & Cons
Lucidspark
Pros
- Facilitation tools such as voting, timers, breakout boards and call-to-me suit remote workshops.
- Security credentials are unusually strong for a whiteboard: SOC 2 Type II, ISO 27001/27701/42001, FedRAMP Moderate and IRAP.
- It works closely with Lucidchart, which Enterprise plans bundle, for teams that diagram as well as brainstorm.
- Over 100 integrations, including Jira, Azure DevOps, Asana, Slack, Teams and Zoom.
- The free plan and 9 to 10 USD per user Team pricing keep the cost of entry low.
Cons
- The free plan allows only three editable boards.
- Reviewers often call the paid subscription expensive for individual users.
- The number of features creates a learning curve for new users, and some find sharing permissions confusing.
- There is no native time tracking, resource management or project reporting.
- Reviewers say chart and data tools are weaker than in Lucidchart.
Slack
Pros
- The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
- Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
- Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
- Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
- Workflow Builder automates routine requests and approvals without code.
Cons
- There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
- Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
- The free plan keeps only 90 days of message history and allows 10 apps.
- Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
- Reviewers report that finding older messages through search can be difficult.
