Ostler is the only AI assistant that knows your life because nothing else has every face, every message, every meeting, every email loaded in – all kept on your Mac, all private to you. Every other product on this page does one slice of that: a chatbot, a memory layer, a wearable, a screen recorder, a search box. This is the honest comparison.
The world does revolve around you.Ostler: $99 Hub once + $9.99/mo Pro (first 30 days of Pro free with the Hub) – cheaper than ChatGPT Plus alone, and your data never leaves your Mac. Privacy isn't a discount, it's the product.

Every alternative does one slice. Kin AI runs advisor avatars on your phone but routes every AI request through its cloud proxy. Perplexity does web search. Poke does iMessage. Omi and Looki do conversation capture from a wearable. Obsidian does notes. Rewind did screen recording (now sunsetting). MyClaw does workflow automation. OpenClaw is the open-source local AI stack you self-host on a separate Linux box. Zo hosts a cloud computer. Google’s Gemini reads your screen and sends it to human reviewers. Apple processes on-device but does not build a knowledge graph. None of them build a knowledge graph of your relationships and life history from twenty platforms of imported data, run entirely on your hardware, with no cloud dependency, packaged so you do not have to be a sysadmin to use it. That is what Ostler does.
Each page goes deeper on a specific competitor: what they do well, where they fall short, and why you might choose one over the other.
At WWDC 2026 Apple shipped deeper personal-context AI: a rebuilt Siri that retrieves from your own messages, photos, and calendar. That is good news. It is also the clearest signal that the category Ostler sits in – an AI assistant that knows your life, kept on your device – is real and now mainstream. See the full Ostler vs Siri comparison.
Ostler is already there, with four differences Apple did not close at launch:
More sources. Ostler pulls from twenty GDPR exports in addition to the seven Apple-native sources Apple Intelligence can reach. Your LinkedIn history, your WhatsApp archives, your old Gmail, your Facebook messages – none of which Apple can see.
Relationship intelligence. Warmth, reciprocity, conversation history, “you haven’t spoken to your mum in three weeks”. That is a product decision, not a platform capability. Apple has not shipped a feature that tells you who you are drifting from.
Lives in your existing messages. Your assistant answers on iMessage and email – wherever you already are. No new app to open, no new habit to build.
On your Mac. Not off your device. The new Siri keeps simple requests on-device, but routes harder reasoning to Apple’s Private Cloud Compute and, for the heaviest queries, to a top-tier model custom-built for Apple silicon (refined using outputs from Google’s Gemini, not running Google’s models) on Nvidia GPUs in Google’s cloud, wrapped in confidential computing. Engineered to be private, but still off your device. Ostler stays on your hardware, full stop.
Apple’s launch was the proof the category is real. Ostler is already there.
If you want a general-purpose AI assistant and do not care about privacy, Perplexity or MyClaw will give you more powerful cloud models. If you want to capture live conversations with a wearable device, Omi or Looki do that. If you want a chatbot in iMessage, Poke charges $10/mo. If you want structured note-taking, Obsidian is excellent and free. If you want a cloud computer, Zo does that. If you want to self-host an open-source local AI stack and you are comfortable with Docker and Linux, OpenClaw is a credible option.
If you want your entire digital life – twenty years of messages, emails, social media, and contacts – organised into a searchable knowledge graph that runs on your Mac with no cloud dependency, and an AI assistant that knows your relationships, that is Ostler. No other product on this page does that.
