Cotypist is a local AI Autocomplete in your voice, anywhere on your Mac Runs AI autocomplete locally on macOS, keeping text data on-device for privacy.
About Cotypist
Cotypist is a macOS autocomplete tool that suggests text as you type, system-wide across your apps.
Its distinguishing trait is that the AI runs locally on the Mac, so the text it processes stays on-device. It also adapts its completions to your own writing style rather than producing generic phrasing.
It fits Mac users who want inline autocomplete everywhere and care about keeping their text off external servers. It is not an option if you are on Windows or Linux, since it is macOS-only, and there is no public pricing listed, which makes it hard to compare on cost before trying it.
Among AI writing aids, it sits on the privacy-first, local-model side rather than the cloud-service side that most autocomplete tools occupy.

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.

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. The durable move before 2027 is to engineer your product to be machine-discoverable and corroborated from day one — even at zero domain authority. Strong in the future means cited, not ranked.
