Everything you need to know about Thremark. Can’t find an answer? Contact us →.
Marks are Thremark’s memory. Every fact, preference, and reminder it learns about you becomes a mark — a visible memory card. You can see all of them, search, edit, delete, or add your own. Nothing is hidden. Your AI uses marks silently in future conversations to give you personalized answers without you having to repeat yourself.
Thremark is built around one idea: memory that’s visible, editable, and yours. You see exactly what the AI knows about you—and you control it. Add to that native iPhone integration, Smart Routing across multiple models, and one surface for chat, files, search, images, and voice. It’s a different product for a different kind of user.
Other assistants may remember things too, often as an opaque summary. Thremark is built around marks—every saved fact is visible, searchable, and editable. Typical vendors vary; this table shows our product shape. A dash (—) means rarely or not at the same depth as native Thremark.
Files are structured documents your AI creates for you — plans, lists, summaries, trackers. Say «make me a weekly plan» and it’s a file. «Track my expenses» — another file. Everything is named, searchable, and always one tap away. You don’t need a separate planner or note app.
Vibe Code is Thremark’s Mac builder: describe a site, app, or automation in plain language and get real code with a live preview. No coding background required. The experience is intentionally simple and native — fewer surfaces than juggling a full IDE and a chat panel, with UI polish aimed at shipping, not demos. Launching on Mac in Q4 2026.
Yes. Logos, mockups, icons, pitch visuals — and everyday stuff too: a portrait, a card for someone, a picture in a style you like. It generates images right in the chat. Available on all plans.
Voice AI (Imprint) is a real-time voice conversation on iPhone. Imprint is hands-free duplex audio with your marks. It listens, understands context from your marks, and responds with voice. Audio streams in real time to a low-latency voice model. Your full memory context is available during the conversation. On the web app, you can use the browser microphone for speech-to-text input into chat; full Imprint is iOS-only.
Yes. When you ask about current events, prices, news, or anything that needs live data — Thremark searches the web and returns answers grounded in real sources. Every claim is cited. Available on all plans.
You don’t pick AI models in Thremark — you pick a vibe. Fast gives instant answers. Smart thinks deeper. Full uses maximum power. Thremark routes each message to the right model automatically. One simple choice.
Your plan changes not just how much you can ask, but how the answer gets generated. Fast mode, available on every plan, is optimized for speed — instant, capable, always responsive. Smart mode activates reasoning-capable models that think before answering. Full mode, exclusive to Pro, routes your request to the highest available tier: deeper reasoning, broader creative range, stronger output on complex topics. In practice: the same question will produce a noticeably stronger answer at a higher plan — not more words, but sharper reasoning. It happens automatically. You don’t request it.
Yes. New users get 7 days of Plus free — Smart mode, higher limits, the full experience. No charge during the trial. You can cancel anytime before it ends through your Apple ID settings. After 7 days it continues as Plus unless you cancel.
Yes. The Free plan includes 1,000 messages, 3 hours of voice, 50 marks, 10 files, 30 web searches a day, and image generation — no credit card required. Plus unlocks smarter models and higher limits. Deep Reasoning is exclusive to Pro.
Free gives you Fast mode with generous limits. Plus is $19.99/mo ($14.99/mo billed annually at $179.99/year) and adds Smart mode — thinking models that analyze deeper. Pro is $39.99/mo ($29.99/mo billed annually at $359.99/year) and unlocks Full mode with the most powerful models, unlimited marks and files, and Deep Reasoning. Annual billing saves 25%.
Yes. Cancel through your Apple ID settings (Settings → Apple ID → Subscriptions). You keep access until the end of your billing period. Your marks, files, and chat history stay — nothing gets deleted when you cancel.
Subscriptions are managed by Apple. To request a refund, visit reportaproblem.apple.com or contact Apple Support. We don’t process payments directly.
Share your referral link from Settings. Both you and the person you invite get 30 days of Plus free. There’s no limit on how many friends you can refer.
Not yet. Subscriptions are currently purchased through the iOS app via Apple’s in-app purchase. If you buy Plus or Pro on iPhone and sign in with Apple on the web, your entitlements carry over automatically. Web billing is planned.
Your marks, files, and chat history sync to Cloudflare’s edge network using an anonymous device ID — not your Apple ID or email. Voice audio streams to LLM providers (Google, OpenAI, Anthropic) for processing and is not stored by Thremark. Cross-device sync requires Sign in with Apple; without it, data stays local to the device.
No. Thremark works without email, name, or Apple ID sign-in. Your device generates a random anonymous ID — that’s what identifies your data. If you sign in with Apple, it enables cross-device sync and links your subscription entitlements. Apple provides only an opaque unique ID, not your name or email unless you choose to share them. We still can’t see who you are.
Yes. In the iOS app: Profile → Delete Account removes everything permanently — marks, files, chats, and your anonymous ID — from all servers. On web: Settings → Erase Everything removes all local data and server data tied to your device. There is no recovery after deletion.
No. Your conversations are sent to LLM providers (Google, OpenAI, Anthropic) to generate responses, but Thremark does not use your data for any model training. We don’t sell, share, or aggregate user data.
Sign in with Apple enables cross-device sync — your marks, files, and chats become available on all your devices (iPhone, iPad, web). Without it, your data stays on the current device. Apple sign-in is also how subscription management works: if you buy Plus or Pro on iPhone, signing in on web links your entitlements. We still can’t see who you are — Apple provides only a unique opaque ID, not your name or email unless you choose to share it.
The web app at thremark.com/app brings Thremark to your browser — no install needed. You get chat with Smart Routing (Fast / Smart / Full), marks, files, live web search with citations, image generation, and speech-to-text — within the same monthly limits as on iOS. Everything syncs between web and iPhone. The only iOS-exclusive features are Imprint real-time voice, Siri, widgets, Dynamic Island, and other native Apple integrations. Paid plans (Plus / Pro) are currently purchased through the iOS app via Apple; web billing is coming soon.
iPhone and iPad (native SwiftUI app) and Web (thremark.com). A Mac app is in development. The web app works on any device with a browser.
Yes, with Sign in with Apple. Once signed in, your marks, files, and chat history sync automatically across iPhone, iPad, and web — changes appear within seconds. Without Apple sign-in, data is local to the current device. The Mac app will join sync when it launches.
Yes. With Plus or Pro, you can export your chat history as text or PDF from Settings. Your marks can be exported as well.
Thremark’s interface is available in 39 languages. The AI responds in whatever language you write in.
30 native Apple technologies: Siri & App Intents, Dynamic Island & Live Activities, Home Screen Widgets, Share Extension, StoreKit 2, Spotlight, StandBy mode, Focus Filters, Handoff, Alternate App Icons, and more. These aren’t checkboxes — they’re deeply integrated into how the app works with iOS.
Sign in with Apple once on any device. After that, your marks, files, and chat history sync automatically via Cloudflare’s edge network. Changes made on iPhone appear on web and iPad within seconds — no manual export or import needed. The sync happens in the background whenever you’re connected. Voice audio from Imprint sessions is not stored and does not sync.
Not much — the web app has nearly full feature parity with iOS for the core experience: chat, marks, files, web search, image generation, and speech-to-text. The iOS app has exclusive features the browser cannot replicate: Imprint real-time voice (duplex streaming), Siri & Shortcuts, widgets, Dynamic Island, and other native Apple integrations. Think of the web app as Thremark anywhere, iOS as Thremark at its deepest.
Not currently. Thremark is built as a native SwiftUI app, deeply integrated with Apple’s ecosystem — Siri, Dynamic Island, and 30+ native APIs. An Android port would mean a fundamentally different product. The web app at thremark.com works on any browser including Android Chrome, giving you chat, marks, files, search, and image generation on any device.
