About
HARPA AI is a browser-based AI assistant and web automation platform distributed as a free Chrome and Edge extension, built to bring AI capabilities directly into everyday browsing without requiring a separate application or subscription. Founded on the principle that AI should work where users already spend their time, HARPA integrates ChatGPT, Claude, and Gemini into a unified interface that operates alongside any webpage — allowing users to summarize articles, draft emails, automate repetitive web tasks, and monitor websites for changes without leaving their browser.\n\nHARPA's feature set spans more than 100 built-in commands covering content summarization, SEO analysis, email drafting, form automation, price monitoring, and web scraping — making it one of the most comprehensive browser AI tools available. The platform's web automation capabilities allow users to record multi-step browser workflows and execute them on demand, positioning HARPA as a bridge between AI writing assistance and lightweight robotic process automation. Target users include marketers, researchers, e-commerce professionals, and knowledge workers who perform repetitive browser-based tasks daily.\n\nHARPA AI has grown to more than 400,000 active users through organic app store and word-of-mouth growth, without major institutional marketing spend. Its free-tier model has driven rapid distribution, while power users upgrade to access higher usage limits and advanced automation features. HARPA competes with browser AI extensions including Merlin and Sider but differentiates through the breadth of its command library, multi-model support, and web automation depth. The combination of AI assistance and browser automation in a zero-install extension fills a gap that neither pure AI tools nor traditional RPA platforms address.
AI meeting transcription platform hit $100M ARR in Mar 2025; 25M+ users; $500K revenue per employee; launched enterprise API and MCP server in Oct 2025
About
Otter.ai is an AI meeting intelligence platform founded in 2016 by Sam Liang and Yun Fu in Mountain View, California. The company was built on the insight that conversations and meetings are the most information-dense and least captured medium in the modern workplace — and that real-time AI transcription could transform how teams capture, search, and act on spoken knowledge. Otter's initial product was a live transcription application that produced searchable, speaker-attributed transcripts of meetings, calls, and voice notes with significantly higher accuracy than existing dictation tools.\n\nOtter's platform has evolved into a full meeting intelligence system that includes real-time transcription, AI-generated meeting summaries, action item extraction, a meeting chatbot for querying transcript content, and integrations with Zoom, Google Meet, and Microsoft Teams. Enterprise features include custom vocabulary, team workspaces, compliance-grade data retention, and an API for embedding Otter's transcription capabilities into third-party applications. In October 2025, Otter launched an enterprise API and an MCP (Model Context Protocol) server, enabling AI agents to query and act on meeting intelligence programmatically.\n\nOtter.ai hit $100M ARR in March 2025, a milestone achieved with 25M+ users and a notably lean cost structure of approximately $500K in revenue per employee. The company has remained privately held and has not disclosed a primary capital raise, operating profitably at scale. Otter competes with Fireflies.ai, Fathom, and Zoom AI Companion in the meeting intelligence market, with its long operating history, transcript search quality, and enterprise integrations as primary differentiators.
