## Knapsack Sidepanel

Knapsack Sidepanel lives in the Chrome side rail, so you can work with an AI agent without switching tabs. Once you connect tools such as Salesforce, HubSpot, Google Drive, Dropbox, calendars or a custom MCP server, the assistant can answer questions grounded in those systems, summarise documents, draft replies and perform data-entry chores. The agent is designed to narrate its plan and let you prompt, modify or stop an action at any point, which keeps a human in the loop on sensitive changes.

Beyond ad-hoc chat, Knapsack supports reusable AI workflows. You can describe an agent or a multi-step task in natural language, share it with colleagues by link, and run it on demand or on a schedule — for example posting meeting notes to your CRM after every call or drafting responses to urgent emails. Because the same panel is available on any site, the assistant can act on the page you are already viewing rather than in a separate workspace.

Knapsack emphasises enterprise-grade privacy: it states SOC 2 Type 2 certification and HIPAA compliance, and lets you control which data the agent may process. The product is aimed at sales teams, executives, consultants and other knowledge workers who want AI grounded in their own business tools. Pricing is not listed publicly — the vendor steers buyers toward a conversation, so plan for a sales-led evaluation.

**Pricing & Plans:** Contact for pricing. No public self-serve tiers are listed; Knapsack is sold through a sales conversation, likely with enterprise tiers.

- **Data-connected side panel:** Connects Salesforce, HubSpot, Google Drive, Dropbox, calendars and custom MCP servers, then answers questions grounded in that data.
- **Agents that plan and execute:** The agent observes your data sources, plans steps and carries out workflows in connected systems with visible reasoning and stop control.
- **Reusable AI workflows:** Build an agent in natural language, share it by link and run it instantly, on a schedule or after meetings.
- **Scheduling and automation:** Automate repetitive tasks such as uploading notes to CRM, generating draft email replies or capturing meeting notes.
- **Security and compliance posture:** SOC 2 Type 2 certified and HIPAA compliant, with controls over what data is processed and shared.

**Strengths:** Works in the browser side panel on any site; Direct connectors to mainstream CRM and storage tools; Human-in-the-loop planning with visible reasoning; States SOC 2 Type 2 and HIPAA compliance

**Limitations:** No public pricing or free self-serve tier; Chrome-only distribution at launch; Value depends on having supported data sources connected; Scheduled automation needs careful data-scope governance

## Tabbit Browser

Tabbit is an AI-native browser built around a simple premise: the browser should understand what you are working on, not just display it. Anything you bring in — open tabs, PDFs, bookmarks, highlighted HTML elements, screenshots, and local files — becomes context for a chat sidebar that can summarize, extract, translate, or act on it. Beyond chatting, Tabbit runs an Agent that plans and executes multi-step web actions, plus an optional CLI for developers.

A distinguishing feature is its library of Agentic Skills: prebuilt workflows for top sites that cover tasks such as triaging a video feed, pulling highlights from long podcasts, downloading Bilibili videos with subtitles, exporting ChatGPT threads to Markdown, extracting tables from research PDFs, explaining pull requests, and auditing subscriptions. Tabbit's agent can run several of these in a multi-agent pattern, and you can build and publish your own Skills. It connects to a very wide range of frontier models, routing each request only to the provider you select.

The company positions privacy as a core principle: highlights, chats, and saved pages stay on your machine, and it states that it does not sell user data or train on your reads. Tabbit is developed by LUMINALAB PTE. LTD. Free and Standard tiers cover most everyday browsing, with a paid Pro tier for heavy agent users and access to top-tier models.

**Pricing & Plans:** Freemium. The browser itself is free forever. A Free tier gives basic AI usage (x1), and setting Tabbit as your default browser unlocks the Standard tier with 10x usage at no cost. Pro is an optional paid plan at US$30.00 per month (billed monthly via Stripe) for 100x usage, top-tier models, full Agent capabilities, 10 scheduled tasks, larger context, and permanent task artifact retention.

- **Everything as context:** Drop in a tab, a file, a screenshot, or a highlighted element and the agent reads, plans, and runs on it — no copy-pasting between apps.
- **Agent and multi-agent web actions:** Automate multi-step tasks on real websites, including deep research, form filling, and data collection, with several agents working in parallel.
- **Agentic Skills library:** Ready-made Skills for the sites you actually use — video triage, podcast highlight extraction, PDF table export, PR explanations, subscription audits — plus a builder for your own.
- **Many frontier models, one browser:** Switch between a broad menu of leading models from multiple vendors, with your chosen model always shown at the top of the chat.
- **Privacy by design:** Highlights, chats, and saved pages stay on your machine, with no data selling and no training on your reads, under independently examined SOC 2 Type I controls.

**Strengths:** Free browser with a genuinely usable free tier and no-cost upgrade path; Agent and Skills turn passive browsing into completed work; Very broad model coverage with transparent routing to the selected provider; Privacy-focused design with local storage of highlights, chats, and saved pages

**Limitations:** Top-tier models and full Agent power sit behind the US$30/month Pro tier; Platform support is currently limited to macOS and Windows; Linux, iOS, and Android are still on the roadmap; Skill quality and reliability can vary by site, since some depend on third-party pages; Heavy agent usage on the free tiers is capped by the x1 and x10 usage allowances
