A HARPA AI alternative with BYOK as the default.

By ReduzReduzUpdated May 11, 2026Reduz vs Harpa AI

HARPA AI is a browser-agent assistant with 100+ predefined commands for summarization, web automation, monitoring, and price tracking. It supports bringing your own AI key on a paid plan. Many readers come looking for an alternative when the job is reading and summarizing sources — not running browser automation — and they want their own AI key as the default. Reduz is intentionally simpler: focused summarization, your AI requests going directly from your browser when you bring your own AI key (no paid tier required), narrower browser permissions, and local history instead of an agent-workflow surface.

Where Reduz fits

Use Reduz when your own AI key should be the default (not a paid-tier unlock), when the job is reading and summarizing sources rather than running browser automation, and when narrower browser permissions matter.

Reduz is a privacy-leaning alternative for readers who want their summary history on their own device, the option to use their own AI provider key, and the same in-tab workflow on YouTube videos, PDFs, articles, and webpages — not just one source type.

The case for Reduz over Harpa AI

Reduz is the right fit when your reading workflow spans multiple source types and you want the data path to be predictable. It runs from the active Chrome tab with click-only permission — the extension can read a page only when you click it. When you bring your own AI key, source text goes directly from your browser to your selected AI provider, with no Reduz server in between. Summary history stays on your device, with optional encrypted backup if you want a copy off-device.

Harpa AI is the right fit when its specific strength matches your job — see the side-by-side table above for the exact tradeoffs.
