H Company Launches HoloTab, an AI Browser Automation Chrome Extension

H Company, a French AI startup, launched HoloTab, a free Chrome extension that runs an AI agent built on the company's proprietary Holo3 screen-control model. HoloTab performs web tasks by observing and replaying user interactions, capturing clicks, typed input, and optional narration to create reusable routines that can be run or scheduled. H Company was founded in 2023 and raised a $220M seed round in 2024, positioning HoloTab as its first consumer-facing product.

HoloTab stitches together vision-based interface understanding, action planning for multi-step tasks, and an execution layer that triggers DOM events and form submissions. Holo3, the underlying screen-control model, achieved 78.85% on the OSWorld-Verified benchmark, the highest reported score to date. Core capabilities include:

• •Teach Mode: record a live interaction (plus optional voice narration) to capture intent, context, and the execution path
• •Replayable, schedulable routines for recurring tasks
• •Multi-tab coordination and cross-site navigation controlled from the extension UI
• •Safety defaults that block sensitive sites such as banks, with user pause, correct, and confirm controls available for irreversible actions

H Company publishes some lightweight models and related blog content on its Hugging Face organization page, which is what has caused some third-party reports to incorrectly describe HoloTab as a Hugging Face product. Hugging Face is a distribution and publishing surface for H Company materials; the model and extension are developed entirely by H Company.

HoloTab sits at the intersection of no-code automation, RPA-style browser scripting, and agentic AI that performs end-to-end web workflows. Its novelty is packaging those capabilities into a single-click onboarding flow that nontechnical users can access. For practitioners, the release moves agentic interaction from research demos and developer SDKs toward consumer-grade tooling, and the Holo3 benchmark number puts H Company in credible frontier territory for computer-use models.

The launch also surfaces practical engineering trade-offs every team building computer-use agents will face: reliability across dynamic UIs, robust selector extraction, handling multi-factor authentication and CAPTCHAs, rate limiting, and the need for human-in-the-loop verification when tasks include irreversible actions. Recording-and-replaying accelerates adoption but can also obscure what the agent will do when web layouts change.

Two signals matter most to monitor. First, the privacy and execution model, specifically whether sensitive inputs are processed client-side or sent to H Company inference endpoints, and what controls exist for enterprises with data-handling requirements. Second, the robustness plan for authentication flows, dynamic content, and failure rollback. Also watch for developer extensions, enterprise controls, and whether routines export as scripts or APIs.

HoloTab is a meaningful proof point that UI-level agents are moving from labs into mainstream browser tooling. For teams building automation or integrating agents into workflows, the combination of a benchmark-leading screen-control model and a zero-setup Chrome extension is worth evaluating on its own merits, and is distinct from anything Hugging Face offers directly.

An earlier version of this article incorrectly attributed HoloTab to Hugging Face and referred to H Company as "Hugging Face's HCompany." HoloTab is entirely an H Company product. Hugging Face is one of several channels H Company uses for model distribution and blog posts, and is not involved in the development of HoloTab. Our apologies to the H Company team and to our readers for the error.
