HARPA AI vs Runner

HARPA AI and Runner are both workflow automation tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

HARPA AI

The extension activates on any webpage via a keyboard shortcut and surfaces contextual AI actions tied to what's on screen — summarize this thread, draft a reply in your tone, extract this table, monitor this price. Web automation tasks like form-filling, data scraping, and page-change alerts run without you staying at the keyboard. The privacy architecture is the real differentiator: conversations are not logged by the vendor, local models are supported, and GDPR compliance is vendor-stated. The ceiling appears when automation sequences grow complex — multi-step conditional flows that depend on dynamic page states push against what the extension model can reliably handle. Teams building more than simple linear automations typically reach for a dedicated orchestration layer alongside it.

Runner

Runner connects to 50+ apps and executes tasks across them — pulling context from email, calendar, chat, and cloud files, then acting on what it finds rather than handing the work back to you. The built-in Chrome browser fires up in the background to unblock searches without interrupting what you're doing, and a permission layer lets you sign off on each action until you're comfortable letting it run faster. Memory accumulates across sessions, so the tool builds a model of how you work over time. The ceiling appears when you need custom conditional logic or integrations outside the supported app list — there's no API to extend it yourself, and no self-hosted option if your data governance policy requires it.

Pros	Multi-model access — GPT, Claude, Gemini, DeepSeek, Llama — from a single keyboard shortcut on any page, so you stop paying for separate subscriptions and stop losing context switching tabs mid-task. Page-aware context means the AI reads what you're looking at before responding, so summaries, drafts, and extractions are tied to the actual content rather than requiring you to copy-paste it into a separate chat window. No conversation logging and support for local Llama models, so teams processing sensitive data avoid the exposure that comes with routing everything through a third-party cloud service. Web automation that runs unattended — price monitoring, page-change alerts, form-filling sequences — so recurring manual checks across dozens of URLs stop consuming working hours. Native integration hooks for Zapier, Make.com, and n8n, so scraped data and triggered automations connect to the rest of a workflow stack without writing a custom API wrapper.	Executes across 50+ connected apps in a single session, so you stop context-switching between tools to assemble the information a task actually requires. Built-in browser automation runs in the background, which means tasks that hit a dead end in a direct integration — venue research, public data lookups — resolve without handing the work back to you. Permission controls let you stay in the loop on every action before Runner takes it, so early adoption doesn't require trusting a black box with your calendar or CRM. Session memory accumulates preferences, contacts, and tool patterns over time, so recurring tasks like weekly exec handoffs stop requiring the same setup instructions each time. Lead enrichment and follow-up drafting happen at the moment a form submission arrives, which means inbound leads don't sit cold while a rep manually pulls context before the first reply.
Cons	Conditional automation logic — branching based on what a page actually returned, not what you expected it to return — is not reliably supported by the extension model. Teams building anything beyond linear sequences hit this wall quickly and end up maintaining a separate automation platform (n8n, Make.com) to handle the branching, at which point HARPA becomes the data-collection layer, not the automation layer. The extension is Chrome-bound and cloud-hosted with no self-hosted option, so teams with strict infrastructure requirements — air-gapped environments, enterprise IT policies that block browser extensions, or deployment targets beyond Chrome — cannot use it at all and switch to API-based agents they control. Writing style mimicry degrades when the volume of content is high and the output format varies. The vendor states the tool generates articles up to 25,000 words, but community reports suggest tonal consistency across long-form pieces with multiple sections requires manual review passes — acceptable for a solo blogger, a problem when a content team is publishing at volume and expecting consistent brand voice without editing overhead.	No API and no self-hosted option mean any integration outside the 50-app catalog is a dead end — teams whose stack includes internal tools or niche SaaS products hit this wall immediately and route those workflows elsewhere. Complex conditional logic — branch on what the last step returned, handle exceptions differently by account type — has no visual or scriptable layer to build it on. Teams with that requirement move to a programmable automation platform and maintain Runner only for the simpler personal-productivity layer. The permission model, while useful early on, adds friction at volume. High-frequency tasks like real-time lead routing require reducing those checkpoints, which shifts risk to users who may not fully understand what Runner will do when unsupervised.

Bottom line

Only HARPA AI exposes a public API. Choose based on which difference matters most for your workflow.
