What It Is

Drop in is a Chrome extension-based tool from Fluid Software Labs UG, designed to add custom features, smart workflows, and third-party integrations on top of existing web apps. Its core idea is not to modify the source code of the original SaaS product, but to overlay a browser-side visual and scripting layer that can be turned on or off. Users simply describe what they need—for example, “show open roles on a HubSpot company card” or “add an export button to GPT conversations”—and Drop in generates the corresponding web enhancement.

Core Capabilities and Integrations

Based on the available content, Drop in focuses on UI injection for arbitrary web apps, quick action buttons, page-context reading, external API calls, and cross-tool data syncing. Example use cases include collecting leads from Google Maps into Airtable, looking up HubSpot contacts from LinkedIn, generating smart replies in Slack, and tracking YouTube watch time. Listed integrations include Airtable, Google Sheets, HubSpot, Notion, OpenAI, Personio, Pipedrive, and YouTube; Attio, Dropbox, Figma, Google Calendar, Jira, Outlook, Slack, and others are marked as Coming Soon.

Pricing, Collaboration, and Security

Pricing information is limited. The product is described as Free to try, with paid plans unlocking more features, higher limits, and team controls, but no specific prices are disclosed. For teams, Drop in supports sharing features and standardizing the same UI improvements across an organization. On security, the product states that users can control what each feature is allowed to read and modify, and revoke access on a per-site basis. Data is only sent to servers when a feature requires it, such as when calling an external API; otherwise, it remains local. However, the main content does not provide enterprise compliance details such as SOC 2, ISO 27001, data residency, or audit logs.

Pros, Cons, and Who It’s For

The main advantages are that it requires no source-code access, has a short onboarding path, and can apply to a wide range of tools. It is especially suitable for sales, support, operations, and growth teams that need to add lightweight functionality to the SaaS products they already use. The drawbacks are its strong reliance on a Chrome extension, and feature stability may be affected by changes to the target website’s DOM or interface. Pricing, permission granularity, enterprise support, and compliance information are also insufficiently documented. Its accessibility from China cannot be determined from the available content; if a team depends on overseas services such as Google, HubSpot, OpenAI, or Slack, real-world availability and payment support should be verified separately. Alternatives include Zapier, Make, Bardeen, Tampermonkey, or building an in-house browser extension.
