6 Best Dimension Alternatives in 2026
Dimension is a proactive AI assistant that wires into Gmail, Slack, Linear, Notion, GitHub, and Google Calendar — drafting replies, briefing you before meetings, watching for deploy failures, and tagging email in your tone. Pitched at engineering teams as the “coworker that never sleeps.” The friction: it’s strongly tied to engineering workflows (deploy logs, PRs), and the value is uneven if you’re not in that exact context. Here are six alternatives.
1. Carly
Carly is an AI agent platform you email like a colleague. You give each agent its own name and email address, then forward or CC her into the work — she executes across 200+ integrations on both Gmail and Outlook / Microsoft 365.
What makes it different from Dimension: Dimension watches and suggests in a dashboard; Carly waits in your inbox and acts on the work you forward her. Dimension is best when you’d rather scan a digest. Carly is best when you’d rather hand work off to a teammate.
Best for: Founders and operators who want to delegate work, not get reminded about it.
Pricing: $35/month
2. Lindy
AI agent builder with proactive triggers — incoming email, CRM updates, calendar events — and a strong template library.
What makes it different from Dimension: Lindy lets you build the agent; Dimension comes with the behaviors pre-built. Lindy is more configurable; Dimension is faster to start with.
Best for: Teams that want custom proactive agents with full control over triggers.
Pricing: Free tier; paid from $49.99/month
3. Glean
Enterprise search + AI assistant across Slack, Drive, Confluence, GitHub, and more. The “answer questions about your company” layer.
What makes it different from Dimension: Glean is search-first (you ask, it answers); Dimension is proactive (it volunteers). Glean is enterprise-priced and deeper on the search problem.
Best for: Mid-size and enterprise teams that need cross-tool search across a sprawling stack.
Pricing: Custom
4. Dust
AI assistant platform for building company-specific agents on top of your data sources. Strong on customization and on-prem options.
What makes it different from Dimension: Dust is a platform to build agents on your data; Dimension is a finished product. More work to set up Dust; more control over what you get.
Best for: Engineering-heavy teams that want to build internal AI agents themselves.
Pricing: 15-day trial; from €29/user/month
5. Cursor (Background Agents)
AI code editor with background agents that work on tickets, PRs, and CI issues asynchronously.
What makes it different from Dimension: Cursor is code-first; Dimension is comms-first. Both target engineering workflows but at different points — Cursor writes the code, Dimension manages around the code.
Best for: Engineers who want AI doing code work while they’re in meetings.
Pricing: From $20/month
6. Granola
AI notetaker that turns rough meeting notes into polished summaries with action items. Records locally on your laptop without joining as a bot.
What makes it different from Dimension: Granola is just meetings; Dimension is everything around meetings (briefs, follow-ups, deploys). Granola does its one job well.
Best for: People who only want meeting capture, not a full proactive assistant.
Pricing: Free tier; Business from $14/user/month

FAQ
Is Dimension only for engineers? The deploy-watching and PR-context features are engineering-specific, but the email/meeting/comms layer applies to anyone. Non-engineers will get less out of the price.
What’s the closest “do work for me” alternative? Carly — you delegate work over email/text and she executes across your tools. Dimension surfaces work; Carly does work.
Can I get Dimension’s briefings without all the other features? Town has a similar “morning brief” pattern. Plain Granola + a daily calendar review covers most of the meeting-prep use case.
