TAMSIV Web is Live: Tasks, Memos, Calendar, and AI Assistant in Your Browser
In February, TAMSIV's public roadmap showed a discreet line: "Web application, in development." Five months later, it's live. Since July 20, you can open tamsiv.com on any computer, log in, and find all your tasks, memos, shared binders, and calendar events on a large screen. With, as a bonus, something that even the Android app doesn't have in this form: an AI assistant in the sidebar, present on every page, that works with you via chat.
This article explains what has been delivered, how it all integrates with the mobile app, and why it took a solo developer five months to turn a roadmap line into a usable product. It's a launch, but it's above all the logical continuation of a conviction: your lists should never depend on the device you have in your hand.
Key points
- TAMSIV Web is a complete browser dashboard: tasks, memos, shared binders, calendar, and settings, synchronized in real-time with the Android app.
- An AI assistant in the sidebar accompanies every page: it creates and modifies tasks, memos, and events via chat, understands the context of the open page, and knows your shares.
- Registration is public: email with verification code, referral, password recovery, magic links, and login with a QR code scan from mobile.
- No iPhone app yet? TAMSIV Web works in the browser of an iPhone, iPad, Mac, or any machine.
- Everything is free at launch, with the same Free, Pro, and Team plans as on mobile: one account, two screens.
What exactly is TAMSIV Web?
TAMSIV Web is not a showcase or a "lite" version. It's a complete workspace, accessible after logging in at tamsiv.com, organized into five areas: tasks, memos, groups, calendar, and settings. Everything you create on the web appears on your phone in a second, and vice versa. Same account, same data, same real-time engine.
The difference is the screen. On mobile, TAMSIV excels at capture: you dictate an idea while walking, the AI puts it in the right place. On a large screen, you switch to organization mode: reordering a binder of fifty tasks, rereading a long memo, preparing the week in the calendar, cleaning up shares. The two gestures are complementary, and that's exactly why the web was never conceived as a replacement for the Android app, but as its large-screen companion.
Registration is now public and complete: you create an account with your email and a one-time verification code, you can enter a referral code to unlock associated rewards, reset your password independently, or log in via magic link without any password at all. An account created on the web works immediately on the Android app, and vice versa.
How to log in: QR code, email, or magic link?
The fastest way remains the one WhatsApp Web users know by heart: you open the login page on your computer, a QR code appears, you scan it with the TAMSIV app on your phone, and the session opens without typing a single password. This mechanism, built on secure real-time channels, had been detailed on this blog in February, when the dashboard was still just an internal prototype.
If your phone is not within reach, two other doors exist: classic login by email and password, and the magic link sent by email. Three paths, one goal: that access friction is never an excuse to let an idea get lost.
What can the AI assistant in the sidebar do?
This is the part I'm most proud of with this launch. On every page of TAMSIV Web, a chat sidebar accompanies you. It's not a decorative chatbot: it's the same brain as the Android app's voice assistant, adapted for the keyboard.
Specifically, the assistant can:
- Create and modify tasks, memos, and calendar events directly from the conversation. You type "add a shopping task for Saturday to the Home binder," it's done, and the page updates before your eyes.
- Understand the open page. If you're on the calendar, it knows which week you're looking at. If you're in a binder, it knows which one. "Move that one to tomorrow" finally makes sense to a machine.
- Know your friends and your shares. You can ask it "what am I sharing with Marie?" or "assign this task to Paul," it knows who you're talking about.
- Search for you, by keywords or by people, in your tasks, memos, and events. Search becomes a sentence, not a form.
- Respond in Markdown, with lists, tables, and readable formatting when the answer deserves it.
And above all, it applies the same safeguards as on mobile. An assistant modifying a forty-line memo should never rewrite ten lines and lose the other thirty. The backend refuses any rewrite based on truncated content: the assistant must prove it has read the actual content before touching it. This anti-truncation safeguard, built and hardened on the voice application, now also protects every modification made via chat on the web. Your content is more important than the AI's convenience.
Is parity with the Android app complete?
For everything related to viewing and organizing, yes, and that was the obsession of the last few weeks. The consolidated feed, which aggregates activity from your binders and shares, is on the web. The calendar is complete and clickable: each event opens, can be modified, and moved. Referral is integrated, with your code and invitation tracking. Reactions, comments, and collaborative checklists work just like on mobile.
Navigation in binders even benefits from the large screen with two view modes: a flat view, familiar, and a tree view that displays your binders like a true file explorer, with a split view to browse a folder on the left and its content on the right. When your binders are six levels deep, a 27-inch screen changes lives. Your view preference is saved in your profile and follows you from one session to another.
One assumed difference remains: voice remains the territory of mobile. Dictating a shopping list to your phone in the kitchen will always be more natural than talking to your computer in an open-plan office. The web captures via keyboard and chat, mobile captures via voice. Each screen does what it does best.
What if you're on iPhone?
Let's be frank: there's no TAMSIV app on the App Store yet. This is the most frequently asked question, on the Play Store, by email, in comments. The answer has long been "it's planned, follow the roadmap." Since July 20, it has become more useful: TAMSIV Web works in Safari on iPhone and iPad, as in any browser.
You can create your account, manage your tasks and memos, consult the calendar, participate in your family's or team's shared binders, and chat with the assistant. If a friend on Android shares a binder with you, you are no longer a spectator: you collaborate in real-time, from the browser. The site even suggests it itself: on iPhone, the download button directs you directly to the web application. The native iOS app remains on the roadmap, but the wait is no longer a blocker.
Why five months between announcement and delivery?
Because "a web app" is a short phrase for a long project, especially when alone. The first building block existed in February: an internal dashboard, mostly read-only, described in the article on the web calendar and monitoring. Between this demo and a product that one dares to open to the public, there is everything that is not seen.
There's full authentication: public registration with email verification code, referral at registration, password reset, magic links, transactional emails in six languages. There's security: every function exposed to the web has been audited so that an account only ever sees its own data and its legitimate shares. There's functional parity, feature by feature, from the feed to checklists. And there was the assistant, which alone represented weeks of work: teaching it the context of each page, giving it access to friends and shares without ever bypassing permissions, and hardening the safeguards so that a chat modification never destroys content.
Five months, then, between the "in development" line and the product going live. No date announced in advance, no countdown: the published version is the one I've been using myself every day for weeks. That's my definition of an honest launch.
How much does TAMSIV Web cost?
Nothing more than what you already pay, which means potentially nothing at all. TAMSIV Web is included for all accounts, free and paid. The plans remain the same as on mobile: Free for organizing without limits on binders or tasks, Pro and Team for advanced uses and larger groups. Your plan follows you, regardless of the screen. There is no separate "web" subscription, and there never will be.

Yes. TAMSIV Web is included with all TAMSIV accounts, including the free plan. The Free, Pro, and Team plans are the same as on the Android app, and the web adds no additional cost.
Do I need the Android app to use TAMSIV Web?
No. Registration is public on tamsiv.com: you can create an account with your email and a verification code, then use the entire dashboard without ever installing the app. The Android app adds voice capture and push notifications, but it is not required.
How do I log in to TAMSIV Web from mobile?

Does TAMSIV Web work on iPhone and iPad?
Yes. TAMSIV Web works in Safari and any recent browser, on iPhone, iPad, Mac, Windows, and Linux. While waiting for the native iOS app, this is the official way to use TAMSIV on an Apple device, and the site automatically directs you there.
Is data synchronized between web and mobile?
Yes, in real-time. The web and mobile share the same account and database: a task checked on the computer appears checked on the phone in a second, and vice versa. Data is hosted in Europe, in Paris, in compliance with GDPR.
