SelfManager.ai vs Tarsen: date-based planner or voice-run Kanban

Picture two people with $49 to spend on a task app. One is a consultant who gets asked on a Friday exactly what happened last Tuesday. The other is a founder whose board is three weeks out of date because dragging cards across columns always feels like something to do later. Both end up in AppSumo’s task management category, and both find a $49 lifetime deal that fits.

SelfManager.ai and Tarsen look alike on the price tag and very different everywhere else. We haven’t used either one, so everything here comes from the listings, which are marketing copy. Where they go quiet, we’ll say so.

Date first or board first

SelfManager.ai treats each date as its own workspace. Inside a day you can create unlimited tables for client work or personal goals, with priorities, completion status and time spent, plus notes, comments and reference images. You can pin tables and browse earlier dates. There’s no setup and no templates, which is a relief if you’ve ever over-built a Notion workspace and then abandoned it.

Tarsen is a drag-and-drop Kanban board. It has cards, comments, assignments, live sync without a refresh, and a permanent ticket number on every card. If you’ve used Trello, you already know the layout.

Here’s the practical split. A date-based tool is good at answering what you did and when. A board is good at showing where work stands right now.

SelfManager.ai’s listing doesn’t explain how a project that runs for months is tracked across days, or whether unfinished tasks roll forward. That’s a real gap if your work is long-running client deliverables. Tarsen has a different blind spot: its listing says nothing about time tracking or reporting.

What the AI actually does

SelfManager.ai points its AI at your history. AI Plan turns a plain-English goal into a draft schedule for 1 to 31 days, with one table per day and up to 20 tasks in each. You review and edit before anything is saved, which we like. AI Review then reads your recorded tasks, statuses and logged time across a week, month, quarter or custom period, and lets you ask follow-ups such as where your time went. It only has something to say if you log time and mark tasks done.

Tarsen points its AI at the chore of updating the board. Press Cmd+J, say what moved, and the card changes. The FAQ says 24 voice commands act on your real board, and it confirms before deleting anything. Mission Mode builds a day plan from the hours you have, using due dates, priority, staleness and blocked status, and it works without an AI key. Ask Tarsen answers questions from your own boards and can propose cards from pasted notes, but nothing changes until you confirm.

Both can turn messy notes into tasks. Neither listing shows sample output, so we can’t say which does it better.

Price, tiers and the numbers that don’t add up

SelfManager.ai has one tier at $49, listed at $216. You get lifetime access and future plan updates, you must redeem within 60 days, and the deal isn’t stackable. The big hole is credits. The listing says AI features use them, but it never says how many the lifetime tier includes, whether they reset, or what happens when they run out. For a product sold on its AI, that’s the first thing to ask about.

Tarsen has three tiers: $49 (was $399), $99 (was $599) and $149 (was $898.72). You have 60 days to activate and can move between tiers. Its limits are messier. The plan features show three numbers per limit: 30 / 45 / 15 voice minutes, 1000 / 500 / 300 Ask requests, and 10GB / 5GB / 2GB of storage. Nothing labels which number belongs to which tier, and the orders don’t match each other. The FAQ mentions 15 voice minutes and 2GB, which suggests the $49 tier is the smallest, but that’s our inference. Confirm before paying for a higher tier.

Voice has a running cost too. Past 15 minutes a month, shared across the whole workspace, you add your own OpenAI key and pay OpenAI directly. Still, that rule is written down, which is more than SelfManager.ai offers on credits.

Tarsen also lets you export any project to JSON or CSV at no charge, and it has a free plan with every feature except adding team members. SelfManager.ai’s listing mentions neither an export option nor a free plan.

Teams, agents and rough edges

SelfManager.ai’s listing mentions a Team plan at a flat $30 a month for unlimited collaborators. It doesn’t say whether the lifetime deal includes collaboration, so don’t assume a virtual assistant or business partner can share your workspace. It also names no integrations.

Tarsen’s FAQ allows three people per code, up to nine on three codes. The tier text says ‘no codes, no stacking’. Those two statements clash, so don’t count on nine seats until someone confirms.

Tarsen’s standout is its built-in MCP server for Claude, Gemini, Cursor, Copilot and Windsurf. It exposes 13 tools, 5 read-only and 8 that can change something, and scoped keys hold an agent to its own assigned work. If you build with AI coding agents, that’s a genuine reason to choose it. If you don’t, ignore it.

On mobile, Tarsen is upfront that it’s responsive but not mobile-first. We can’t see anything about mobile in SelfManager.ai’s listing.

Track record is the other difference. SelfManager.ai claims development since 2016, a public launch in 2022 and thousands of registered users. That’s the seller’s own claim, and a 2026 domain move plus a v4 redesign could mean rough edges. Tarsen’s listing gives no customer counts, roadmap or history, which makes a lifetime bet riskier.

Which one to buy

Pick SelfManager.ai if you bill by the day, you’re happy to log time, and you want a tool that can summarise what you did for an invoice or a client call. Get the credit allowance in writing first.

Pick Tarsen if you think in cards and columns, you keep forgetting to update them, and the idea of speaking changes appeals. It’s also the better fit if you work with coding agents. Expect to pay OpenAI separately if you lean on voice.

If you’re still torn, Tarsen has the easier way to find out, because its free plan costs nothing and you can export your data afterward. SelfManager.ai asks you to commit $49 before you can judge whether a date-based layout suits you.
