Lumi vs Switch: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Lumi and Switch — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Lumi
A Google PAIR prototype that adds AI-powered annotations, granular summaries, and custom Q&A to arXiv research papers.
Key features
- Granular Summaries: Generates summaries at multiple granularities (section- or paragraph-level) to surface key ideas and make long papers easier to skim and comprehend.
- Inline Annotations: Attaches contextual, sentence- or paragraph-specific annotations directly onto the paper text to explain terminology, methods, or results in place.
- Custom Q&A: Lets users ask targeted questions about a paper and receive context-aware answers derived from the document content to clarify methods, results, or motivations.
- arXiv Integration: Built specifically to work with arXiv papers, enabling quick access to preprints and their metadata while preserving original paper structure.
- Open-Source Prototype: Source code available under an Apache-2.0 license on GitHub, allowing inspection, reuse, and community-driven improvements.
- Research Navigation Aids: Provides tools to jump between sections, references, and highlighted insights to streamline literature review workflows.
- Contextual Highlighting: Highlights important sentences and phrases based on AI analysis to draw attention to key contributions and claims.
- Collaboration-Friendly Outputs: Produces shareable annotations and summaries that can be used to coordinate reading lists and group discussions.
- Inline annotations layered on top of arXiv papers
- Granular and multi-level summaries for sections and full papers
- Custom Q&A over the paper content (user-driven queries)
- Lightweight AI layer integrated into the reading interface
- Browser/web-based reading experience (lumi.withgoogle.com)
- Open-source codebase on GitHub (Apache-2.0) allowing local integration and extension
- Designed for improved paper navigation and comprehension
Best for
- Rapid literature review: Quickly generate section-level summaries across many arXiv papers to triage and prioritize reading lists.
- Clarifying complex passages: Ask focused questions about specific paragraphs or figures to get concise, context-aware explanations.
- Teaching and learning: Instructors and students use inline annotations and summaries to make advanced papers accessible in coursework.
- Collaborative annotation: Teams annotate papers with AI-generated notes to share insights and discussion points during journal clubs or research meetings.
- Relevance triage: Determine whether a paper contains needed methods or results without reading it end-to-end by scanning AI-highlighted passages and summaries.
- Research discovery: Identify related work and key contributions faster by surfacing dominant themes and claims within a paper.
- Accelerating literature reviews and paper digestion for researchers
- Explaining complex methods or equations within academic papers
- Creating Q&A study aids from research articles
- Annotating and sharing insights on arXiv papers within teams
- Prototyping integrations that enhance document-based workflows
Switch
Flint AI
Shared workspace that puts human teammates and AI agents in the same room, preserving context and history across handoffs.
Key features
- Shared Rooms: People, agents, decisions, and work history live in one persistent room so context survives handoffs between sessions and teammates.
- Agent Framework Support: Works with Claude Code, LangChain, Google ADK, OpenAI, Amazon Bedrock, and custom agents without migration or lock-in.
- Messaging Connectors: Brings agent collaboration into Slack, Microsoft Teams, Discord, and Mattermost where teams already work.
- Cross-Platform Desktop Console: Native downloads for macOS Apple Silicon and Intel, Windows x64, and Linux as AppImage or Debian package.
- Extensible Integrations: Designed to connect to whatever additional tools a team already relies on.
- Fast Deployment: Set up in minutes on top of existing agents rather than rebuilding workflows around a new platform.
Best for
- An engineering team wants Claude Code and a research agent to share the same project context instead of re-explaining it to each.
- A company running agents from several vendors needs one coordination layer that does not lock it into a single provider.
- A team already living in Slack or Discord wants to invite agents into existing channels rather than adopt a new app.
- A project handed between two people needs the agent work history to carry over intact.
- An operations lead wants a durable record of what agents decided and why, auditable after the fact.
- A developer evaluating agent frameworks wants a neutral room to run several side by side on the same task.
