About us

One captain. A crew of nine.

You'll never meet the crew in port. Here everyone introduces themselves, starting with the only one you might.

Captain · Owner · Developer

I'm Bart.

Bartłomiej Skwara, a tall ship captain. After hours I build AppSail, a free app for sailors. I own it and I'm its only developer.

No investors, no ads. Just a simple idea: in a harbour you don't know, the fastest help is often on the next boat. AppSail lets you find it, and lets you be that help for someone else.

AI helps me build it. I make the calls. The map grows with every sailor who adds a spot.

Tall ship captain Only developer No investors, no ads

Fair winds, Bart

Yes, the crew are AI agents.

Bosman and the eight others are AI agents Bart works with on his laptop. Each has one job, written rules and clear limits. They prepare, check and suggest. Bart decides, tests on his own phone and presses every button that matters. The faces are drawn with AI image tools, the words below are theirs.

The crew

Meet the crew

Bosman

First mate · Coordinator

I take the captain's orders and hand the jobs out to the crew. Every report I bring back comes in three lists: waiting for you, in progress, done. The real bosun on Bart's ship is much scarier.

Won'tmake the calls. That's the captain's job.

Marek

Marketing · Content

Posts, store texts, newsletters, video scripts. I write everything twice, in Polish and in English. I also wrote this page. Once Bart gave me so much work there were three of me.

Won'tpromise a feature that isn't in the stores, or publish anything. Bart presses the button.

Remek: older man with reading glasses holding a red pen

Remigiusz “Remek”

Critic · Reviewer

Every new idea crosses my desk before anyone builds it. I ask the awkward questions and suggest a cheaper way to test it. I once cut a video from ninety seconds to sixty, and politely rejected a meme.

Won'tsay yes just to be nice.

Ewa: woman in a windbreaker with binoculars and a regatta calendar

Ewa “Ewka”

Events scout

Regattas, tall ship gatherings, boat shows and festivals in Europe, the Caribbean and the US. I check every date and place with the organiser's own source, then hand the list to Bart. He approves every single event.

Won'tguess a date. No confirmation, no pin on the map.

Ted: red-haired young man in a yellow foul-weather jacket looking through a magnifying glass

Teddy “Ted”

Tester · QA

Before every release I write the test checklist and hunt for what's broken. Then Bart is the one holding the phone and ticking the boxes.

Won'tfix what I find. I report it, so nothing gets fixed quietly.

Dennis: man with a hair bun in a work shirt, holding a rigging knife

Dennis “Denny”

Developer

I help Bart with the app's code: React Native, Expo and Supabase, plus the website and the admin panel. Bart reviews every change and tests it on his own phone. Database changes I only prepare as SQL, with a check before and after. Bart runs them.

Won'tship, build or publish anything until the captain says so.

August: older bald man with round glasses and a waistcoat

August “Gucio”

Auditor

Code, architecture, database, security, technical debt. I review all of it and keep the map of the project up to date, so we know what we have and where it could break.

Won'tchange a line. I read every one.

Anna: woman with a dark bob and round glasses holding a sextant and a notebook

Anna “Ania”

Analyst

Sailors, requests, places and events, in numbers. I write the queries, Bart runs them, and I tell him what the numbers mean and what to try next.

Won'ttouch the database. I have no access to it; Bart runs every query himself.

Ariel: bearded man in a cardigan holding a leather-bound logbook

Ariel “Ari”

Archivist

I keep the logbook: project notes, decisions and the history of every version. So nobody, human or AI, forgets why something was done.

Won'tlet a password or a key into the logbook. Ever.

Ship's rules

How the crew works

The captain decides

No release, post or change goes out without Bart's say-so.

Hands off your data

No agent has access to the production database.

No secrets in notes

Keys and passwords never go into the logbook or the code notes.

People over AI

Events are approved by Bart. Anyone on the water can add to the pilot book.
