Task Bert is a privacy-first Mac app that acts as a local AI assistant for your iMessage conversations. It runs entirely on-device using local vector embeddings and your own API key (OpenAI or Anthropic), so your messages never touch a third-party server. The assistant can search across your message history, convert casual plans buried in conversations into calendar events and reminders, and surface follow-up nudges for conversations that fell through the cracks. The technical implementation is clean: it uses Hugging Face's nomic-embed-text model for on-device vector embeddings, meaning semantic search across your iMessage history doesn't require cloud calls. When it detects a plan or commitment in a conversation ("let's grab coffee Thursday"), it can write it directly to Apple Calendar and Reminders. The BYOK model puts the user in control — the app acts as orchestration layer, not a data holder. Task Bert targets a real pain point for heavy iMessage users: important follow-ups and plans routinely get buried in high-volume group chats or forgotten in long one-on-one threads. By running locally and integrating natively with Apple's ecosystem, it sidesteps the privacy concerns that have plagued cloud-based messaging assistants.
Reviewer scorecard
“Spaces changed how I work. Work tabs in one space, personal in another, client projects each get their own. Context switching without tab chaos.”
“The follow-up nudge feature alone would pay for this tool. I can't count how many creative collabs have died because someone (usually me) forgot to follow up on a message thread. Having an on-device assistant surface those forgotten conversations without sending them to a cloud server feels like a genuinely ethical approach to AI assistance.”
“Arc is beautiful but the company pivoted to a new product. Updates have slowed. The future is uncertain. Switching browsers is a big commitment for an uncertain product.”
“Apple's iMessage privacy model creates real friction here — accessing message history requires specific macOS permissions that users are increasingly reluctant to grant after recent privacy scandals. Also, iMessage-only limits this to Apple devices, cutting out anyone running a mixed iOS/Android household. The addressable market is narrower than it looks.”
“The dev tools work fine since it is Chromium-based. Boosts for customizing internal tools are useful. The command bar is faster than Chrome omnibox.”
“BYOK + on-device embeddings is the right architecture for a messaging assistant. No cold storage of conversations, no vendor lock-in, no trust required. Using nomic-embed-text locally for semantic search is a smart call — it's fast and accurate enough for this use case without GPU hardware.”
“The local-first AI assistant is the next major product category. Task Bert is an early proof-of-concept for what happens when you give an AI agent read access to your communication history with proper privacy guarantees. As local inference gets faster, every major messaging platform will have something like this — but the indie versions will always be more trustworthy.”
