Fletcher MCP vs Solace

Fletcher is a privacy-first location tracker built for the AI era: it records your movement history, keeps it under your control, and lets your AI assistant answer questions about where you've been — with every access logged in plain sight. TRACK QUIETLY • Battery-friendly background tracking using significant location changes and visit detection • A clear Tracking toggle — when it's off, it's off, with an unmistakably grayed-out map • Live map that follows you, with manual zoom controls YOUR DATA, UNDER YOUR CONTROL • History lives on your device and syncs to the Fletcher sync server — or run the open Fletcher server yourself and point the app at it in Settings • No account, no email, no name: registration is an anonymous device ID • Retention you choose, from 7 days to forever — enforced locally and on the server • Delete a single point, or wipe everything locally and remotely, anytime CONNECT YOUR AI ASSISTANT (MCP) • Fletcher includes a Model Context Protocol (MCP) server — the open standard supported by Claude and other AI assistants • Generate a connection token in the app, paste it into your assistant, and ask things like "Where was I last Tuesday afternoon?" or "How often did I visit the gym this month?" • Precision control: share exact, ~100 m, or ~1 km coordinates with assistants • Revoke a token at any time — revocation takes effect immediately, even mid-session TRANSPARENCY, BUILT IN • Every assistant request is logged: what was asked, when, and how many locations were returned • Review the full request history right in the app • No analytics, no ads, no third-party SDKs EXPLORE YOUR HISTORY • Interactive history map with start and end markers, smooth even with thousands of points • Fast list view with swipe-to-delete • Sync status view with diagnostics and manual controls Fletcher is for people who want the convenience of a location-aware AI assistant without handing their movement history to a data broker. Your location data is used for one thing — your own history — and is never sold, shared, or used for advertising.

``` Solace Buzz is a workspace where people and AI workers do the work together — and where every action a worker takes has an owner, a limit, and a record. Chat is the easy half. Channels, threads, direct messages, search, reactions, an activity inbox: the parts of a team workspace you already know. The half that matters is what happens when a worker acts on your company's behalf. AN AI DEPARTMENT SOMEONE CAN BE HELD TO A worker in Solace Buzz holds a declared seat. It acts under a policy that can refuse it. It spends against a budget that runs out. Everything it does outward leaves an evidence record you can read later, in the room where it happened, next to the humans who were there. An agent that cannot be audited is not staff — it is exposure. A SERVER YOU RUN Solace Buzz pairs to a relay — the server your workspace lives on. Run it yourself and your conversations and records never touch our infrastructure. Would rather not run a server? We host relays too, and the app always tells you which one you are paired with. AN IDENTITY THAT IS A KEY, NOT A ROW You join by scanning a pairing code from your workspace. Your identity is a cryptographic keypair held in the device keychain — not an email address in someone else's user table. Nothing to recover from us, because we hold nothing. BUILT ON OPEN SOFTWARE Solace Buzz is built on Buzz, the open-source workspace from Block, under the Apache 2.0 license. The relay is software you can read, run and keep — the workspace is yours in the sense that matters, which is that you can take it somewhere else. WHAT THIS RELEASE IS An alpha developer preview, and it is honest about that: • A relay is required. Without one, this app has nothing to connect to and nothing to show you. It is not usable standalone. • Features change between builds, and stored data may not survive an upgrade. • Agent seats, budgets and policy enforcement are administered from the desktop and command-line surfaces; the phone is where you read, approve and intervene. If you are evaluating whether an AI workforce can be governed rather than merely prompted, this is the client to carry. If you want a chat app, there are better ones, and we would rather you used those. Solace Buzz — where people and workers build a company together.
