An AI notes app that grew from a smart notepad into an assistant that brainstorms with you and writes the notes itself.
What it does
Let’s work on the go-to-market strategy. Developer communities first, then enterprise.
Writing that down. I’ll structure it as a phased approach.
Created Strategy/Go-to-Market.md
Phase 1 targets developer communities, Phase 2 moves to enterprise. Which communities should we start with?
Flutter first, since that’s our own stack. Then React and Swift.
Updating the note with these specifics.
Updated Strategy/Go-to-Market.md patch_note · +4 lines
Done. Target communities are in Phase 1. Nothing else in the note changed.
Flutter / Dart: our own stack, highest credibility
React: the largest frontend community
Swift / iOS: quality-conscious developers
Open-source contributions and packages
Technical blog posts
Conference talks and workshops
Lean on the case studies from Phase 1.
You brainstorm in the chat. The assistant creates notes, organises them into folders, and edits them as the conversation moves. You never copy anything across.
The key decision
This was the call I cared about most. The assistant edits notes through small, precise tools instead of rewriting whole documents. To change one line, it patches that line. That keeps it fast, and it keeps the bill small.
write_note
Rewrite the whole note

Built in Godot, and live on Google Play.

The warm amber is on purpose: notes should feel like paper, not a dashboard.
Bring your own key
Noteless runs on your own API key. You pay the provider directly, and every request is logged with its input and output tokens and an estimated cost, by chat, project and provider.

How I built it
For v2 I wrote the spec and the design system first, then had AI write the Flutter code against them. I made the calls. It did the typing.
Anthropic, OpenAI and OpenAI-compatible providers like Kimi all plug into the same interface. Switching models never touches your notes.
The assistant can only change notes through a fixed set of tools with strict inputs. It asks before anything destructive.
Projects, notes and chats live in SQLite on the device. API keys sit in the platform’s secure storage.
Golden tests cover the main screens in light and dark, on phone, tablet and desktop layouts.
