sprintrr.ai
An AI project manager I designed, built, and shipped end to end, solo. Describe a project in plain English and sprintrr drafts the tasks, milestones, and timeline. A year-long experiment in taking a product from brand to code to launch to marketing.

I have spent my career designing products and handing them to engineers to build. With sprintrr I wanted to find out if I could do the whole thing myself: the brand, the product design, the code, the launch, and the marketing. One person, end to end.
sprintrr is an AI project manager. You describe a project in plain English and it drafts the tasks, milestones, and a timeline in about a minute. The idea was simple, take a project from chaos to clarity, but building it taught me how much sits between a good idea and a shipped product. This is the story of that year.
From chaos to clarity
Every project I run starts the same way: a blank board, a pile of half-formed ideas, and an hour of admin before any real work begins. Project tools are good at storing a plan once you have written it. They are not much help writing it in the first place. That blank page is where most momentum dies.
sprintrr starts there instead. You type what you want to build in plain language, and it returns a complete, editable plan, milestones, sequenced tasks, estimates, and categories, in about sixty seconds. From there it behaves like a normal project tool: a board, a timeline, analytics, and collaboration. The difference is that the cold start is gone.

Turn ideas into actionable plans
This is the core of the product, so it had to feel effortless and be genuinely reliable. You describe a project, and the AI returns a structured plan you can review, tweak, and turn into a live workspace.
What I built
A generation flow that reads a plain-English brief and produces milestones, sequenced tasks with estimates, and a timeline. Everything is editable before it becomes a project, so the AI proposes and you decide.
Making the AI reliable
Getting a model to return valid project structure every single time was the hard part. Long responses love to wander and truncate the JSON mid-object, and different providers fail in different ways. I built a provider-agnostic repair layer that strips code fences, escapes stray control characters, and balances truncated brackets so a plan never fails to parse. A validation pass then drops anything the model hallucinated before it reaches your board.
Quality or speed, your choice
Generation runs through a provider abstraction rather than a single hardcoded model. Quality mode uses Claude Sonnet for fidelity; Speed mode swaps in Gemini for a faster draft. If you would rather use your own model, bring your own key and your sprintrr credits pause, preserved, not consumed.
Everything you need to ship faster
A generated plan is only useful if the workspace around it is good. Once a plan exists, sprintrr is a full project tool: a Kanban board, a Gantt timeline, analytics, milestones, and a calendar, all on the same data. I designed and built every view.
A few decisions I am happy with
- Status-driven time tracking: no start and stop button. Time accrues as a task moves through In Progress, so the tracking is honest without anyone babysitting a timer.
- An editorial Gantt: the timeline snaps to real week boundaries with milestone diamonds and deadline markers, rebuilt to read like a plan rather than a spreadsheet.
- Hand-rolled analytics: the charts are drawn in SVG, not a charting library, to keep the dashboard fast and on brand.

Talk it through, and it files the tasks
Plans drift in meetings. Decisions get made out loud and never make it back to the board. So sprintrr reads transcripts.
Paste the text from any call, Zoom, Teams, Meet, Otter, Fireflies, or hand-typed notes, and it reconciles what was said against your live project. It proposes new tasks, status updates on existing ones, and the cancellations the call actually decided. Nothing auto-commits: you review the diff, uncheck anything, then apply, and removals are opt-in by default.
The same reliability problem, reused
This feature leans on the same JSON repair layer as generation, plus a check that validates every proposed task against the real ones in your project, so a hallucinated reference is dropped instead of corrupting your board. Honest by construction.
A week of work, in one update
Writing a status update is the chore nobody wants. sprintrr drafts one from what your team actually did, the tasks completed, milestones moved, and risks flagged, then ships it to Slack or email. About ten seconds to generate, a couple more to edit.
You can put it on a schedule for a Friday-morning draft, but it never auto-publishes. Every send is a deliberate click, because a bot quietly emailing a stale report to your stakeholders is exactly the kind of thing that erodes trust.
Wire it into the tools you already build with
I built sprintrr with Claude and Cursor, so it felt obvious that it should connect back to them. sprintrr ships its own MCP server: one npx command gives Claude Desktop, Claude Code, and Cursor around thirty tools to read and modify your projects, tasks, and milestones. Prefer your own scripts? The same tools are available over a plain HTTP API with the same scoped, revocable keys.
The bring-your-own-key story runs deep too. Connect your own Anthropic, OpenAI, or Gemini key on any plan, and every AI or agent change is attributed to a named key in an Activity feed, so there is always a reviewable audit trail of what changed and who, or what, changed it.
Take it to market
Building the product was only half the brief I set myself. A product nobody hears about is a hobby, so I ran the go-to-market too: the brand, the landing page, the launch, and a set of short ad spots that put the real product on screen.
I produced the creative myself, screen recordings of the generate flow and the board, cut against a calm brand and the line that holds the whole thing together: from chaos to clarity. These ran as paid social, and shaping them taught me as much about positioning as the product did about engineering.
How I built it
sprintrr is a Next.js and TypeScript app on Supabase, with Postgres row-level security scoping every record to its owner. The AI runs through a provider layer that can call Claude or Gemini or a user's own key. Ask, the question-answering feature, retrieves context with Gemini embeddings stored in pgvector. Billing is Polar, hosting is Vercel, and Slack and Jira plug in at the edges.
I pair-programmed the whole thing with Cursor and Claude Code, roughly seven hundred and eighty commits across a year, sixty-four database migrations, and more late nights than I will admit to. The least glamorous and most important part was a security and compliance program I documented in the open: encryption, multi-factor auth, data export and deletion, and SOC 2 and ISO 27001 readiness, written down rather than claimed.
Reflection
sprintrr is in early access. I am not going to show you logos or testimonials I have not earned. What I can show is a working product that turns an idea into a structured plan in about a minute, an MCP server and API that real developers can wire up today, and a security program written down in the open.
The thing I take away is less about project management and more about what one person can now build. A few years ago, a single designer shipping a full SaaS, brand, product, code, payments, and marketing, would have been a stretch. With Claude and Cursor as the engineering team, it became a year of evenings and weekends. We are early in this shift, and I wanted to feel its edges by building something real rather than reading about it.
That is the most honest outcome I can offer: not a metric, but a product you can open right now.
