A lot of "all-in-one" work platforms solve the wrong problem. They bundle a dozen half-built features under one roof and call the roof the product. You get one login, sure — and then twelve mediocre tools instead of three good ones.
Oestler takes the opposite bet: keep each tool small enough to actually be good at one thing, and let the "one account" part do the boring, unglamorous work of not making you re-sign-up, re-invite your team, and re-learn a new interface every time you need a different kind of tool.
Three Tools, Each Built for One Job
Simple Presentation is a freeform canvas for diagrams and process maps — templates, a real shape library, presentation mode, export. Simple Kanban is boards and drag-and-drop cards, organized into folders, with CSV export and workspace reporting. Simple Checklists is reusable, versioned templates with a full audit trail. None of them try to also be the other two.
That restraint is deliberate. A kanban board that's also trying to be a diagramming tool ends up worse at both. Three focused tools, each genuinely good at its own job, beats one tool that's fine at everything.
One Login, Not Three
What ties them together isn't a shared data model pretending everything's one big connected system — it's simpler than that. One account works across every Simple tool. Invite a colleague once and they can be added to boards, checklists, and diagrams without a separate signup for each. Folders and sharing work the same way in Kanban as they do in Presentation, so switching tools doesn't mean relearning who has access to what.
The goal isn't to pretend three different tools are secretly one platform. It's to make sure the account underneath them never gets in your way.
Where They Actually Connect
There's exactly one place the tools genuinely link up, and it's a real one: link a Simple Checklists template to a Simple Kanban board, and every card on that board gets its own tracked checklist instance automatically. A recurring process — onboarding a client, closing out a task, running a review — gets its checklist attached to the card it belongs to, instead of living in a separate tab you have to remember to check.
That's the honest shape of the integration: not a sweeping claim that everything talks to everything, but one specific, useful connection between two tools that are often used together anyway.
Small Tools, Done Properly
The pitch isn't a sprawling platform that does everything passably. It's a family of tools you can pick up individually — start with just Kanban, add Checklists when you need it, bring in Presentation when you're ready to map out a process — without ever feeling like you're assembling a system nobody designed on purpose.
