About Monica
Monica is a browser-extension AI assistant that lets you chat, summarize, rewrite, translate, and answer questions on any web page.
Its edge is breadth in one place: it supports multiple models including GPT, Claude, and Gemini from a single interface, reads and acts on page context across any site, and lets you bring your own API keys for supported providers.
It fits people who work mostly in the browser and want those actions inline on whatever page they're on. It is a poor fit outside that context — its primary value comes through the extension, so it is less useful outside the browser workflow, and the free tier caps daily messages and advanced features.
Compared with standalone AI chat apps, it trades a dedicated app for in-page reach across any website plus multi-model and BYOK support.

- How to Get Your AI App Cited by ChatGPT and Perplexity
To get cited by ChatGPT and Perplexity, be the clearest answer in several places at once. Publish answer-first pages with extractable facts, get listed on directories and review sites the engines crawl, and build consistent mentions across Reddit, YouTube, and your own site. Perplexity tends to favour recent content; ChatGPT appears to weight agreement across sources.

If you built something with AI, posting is getting hard to ignore. GaryVee's 'interest media' shift is real — more feeds now recommend content by interest, not only by who follows you — so a maker with zero followers can sometimes out-reach an established brand. That's the unlock and the mandate: building got faster, getting seen is the job, and many products struggle to grow without it. Here's the honest first move, written for a builder who would rather ship a feature than post.

When AI makes building a product trivial and floods the web with generic content, marketing inverts: distribution becomes the moat, and distribution increasingly means being the source AI answer engines and buying agents cite and recommend.
