The First Sailing App
for the AI Age.

axiotrax is built with AI at its foundation — not as a feature, but as the engine. It records your sailing, replays every moment, and puts an AI coach in your pocket that actually knows what happened on your water. Free to use. Genuinely powerful.

New to axiotrax? Start with the User Guide — the first page tells you what it does in four steps.

"No athlete reaches their potential without a coach."

Now every sailor has one.

SmartCoach · AI

It reads your race.
Then coaches you on it.

SmartCoach doesn't give generic sailing advice. It reads your GPS track — every tack, every VMG split, every moment you gained or lost — then debriefs you the way a good dock coach would. Direct. Specific. Based on what actually happened.

"What happened to boat speed here?" "Was that tack worth it?" "Where did the upwind go wrong?" It knows the data. You ask the questions.

  • Reads your actual GPS — speed, VMG, tacks, every leg
  • Scrub to any moment — tap the map, ask "what happened here?"
  • ORC VPP polars — tells you how close you got to target

Coaches and clubs — we would rather build this with you

SmartCoach is for the boats you cannot be on. It is not trying to replace what you do on the dock; it is trying to make sure every boat in your fleet turns up to that conversation with the evidence already assembled.

If you run a program, we will shape the coaching to fit it — your language, your priorities, the things you drill and the order you teach them in. At no cost. We would rather learn how good coaches actually work than guess at it.

Personalized Coaching

You tell it what
you're working on.
It coaches you there.

Not every sailor needs the same debrief. Tell SmartCoach whether you're focused on boat speed and trim, or tactics and VMG — then add a note about what you're specifically trying to fix. The coach reads it, and it shapes every conversation. Not a script. Just context.

Speed & Trim

Heel, traveler, outhaul, sail shape — going as fast as possible. Coach leans here first.

Balanced

Follow the data and the question. Speed when speed matters. Tactics when tactics do.

Tactics & VMG

Shifts, laylines, favored side, positioning. Sailing in the right direction, not just fast.

Add a free-text note — "I tack too early at the mark" or "I lose pressure in dying breeze" — and the coach uses it to connect what it sees in your data to what you already know you're working on.

Video Overlay

Data-rich video.
One tap.

Boat speed, VMG and compass. Polar percentage against your boat’s own targets. A live wind rose carrying true and apparent wind, wind speed and your upwind laylines. Course leg, mark, and a track that draws itself as you sail. All of it stamped onto every frame — automatically synced to your GPS, and to your instruments when you have them.

Select your video. Tap Render. Done. Pro subscribers get clean, branded export. Free users get a watermarked version — still genuinely useful, just with the axiotrax badge.

Curated Cohort · Pro

Race your cohort.
Coached as one.

The hardest part of learning from a fleet was never the sailing — it was collecting everyone's tracks afterward. Cohorts kill that step. Pick the handful of boats you want to measure yourself against, go race, and their sessions show up on their own. No group chat, no AirDrop scramble, no "can you send me your file?"

That's the magic underneath: every boat's races live in that boat's own iCloud, and axiotrax quietly assembles your cohort view from the boats you follow. Nobody hosts the fleet. Nobody's data leaves their own account. You join once — and it keeps flowing, race after race.

Then SmartCoach goes to work across the whole group. Not you against a fleet average — you against the specific fast boats you chose. Where did the leader gain? Which side paid for the boat that beat you off the line? Ask, and it answers with the cohort's real tracks.

Learn from the best — not the bottom of the fleet.

  • Join once — the cohort's tracks appear on their own, every race
  • Every boat's data stays in its own iCloud — nothing centralized
  • Benchmark against the boats you choose, not the whole fleet
  • SmartCoach coaches you across the cohort's real races

Compare · Pro

One race.
Two tracks.

You do not need a cohort for this one. Somebody sends you their race — a crew share, a Vakaros file, whatever they have — and you put it on the map next to yours. Ad hoc, one race at a time, nobody following anybody.

Play it back and axiotrax calls the advantage in boat lengths: who was ahead, by how much, and the moment it changed. That is usually a tack, and it is usually one nobody remembered afterwards.

SmartCoach is watching both boats now, so you can ask about the split, the cross, or the leg where it came apart. If you already follow boats in your cohort, their races show up here too.

  • Both tracks on one map and one timeline
  • Advantage measured and called in boat lengths
  • Any race someone sends you — no cohort needed
  • Up to three other boats, not just one

Built with AI at its core

Fast.
Automatic.
Intelligent.

axiotrax is built with AI at its foundation — not bolted on as a feature. That means the app gets smarter, ships faster, and delivers more value every week.

SmartCoach AI

Your AI coach reads every session — speed, VMG, every tack — and debriefs you like a dock coach would. Tell it what you're working on and it focuses there. Speed and trim, or tactics and VMG. You choose.

Record, Import, Replay

Record direct from iPhone with race countdown built in. Import from Garmin FIT or Apple Watch. Every session logged, heat-mapped, and searchable. Works how you already sail.

Video Overlay

One tap renders your complete performance data onto your sailing footage. Speed, VMG, compass, track map — frame-precise. Pro users get clean branded export.

Under the hood

Built different.
Provably.

Most “AI features” are a chat window bolted onto an app. SmartCoach is the other way around — the coaching architecture came first, and it does four things no other sailing app does.

It never blames you for a shift you couldn't see.

SmartCoach reconstructs the wind for your whole race — then asks one question before it critiques any decision: could you have known, at that moment? A correct call that got rolled by an unknowable shift gets credit, not blame.

gun finish reconstructed wind 12° shift arrives your call here unknowable — not your fault your call here knowable — coachable moment

It asks your race for the numbers.

Mid-conversation, the coach queries your actual GPS record — your tacks, your legs, your start — and answers with your numbers, not generic advice. You'll see it work: “Analyzing your tacks…”

Why was my second beat slow? Analyzing your tacks… your GPS record (on device) Three of your seven tacks on that leg lost over 8 m each — all three entered below 4.2 kt. Carry speed into the turn before you commit.

It fact-checks itself before it speaks.

Every coaching answer is checked against your real data — on your phone — before you see it. If the AI's claim doesn't match your GPS record, you see the correction, not the mistake.

AI's draft “…you tacked 9 times” checked against your GPS record actual tacks: 9 ✓ you see it If the claim doesn't match your data, it's corrected or flagged — before it ever reaches you.

It scores the tacks you took — and the ones you should have held.

Every tack gets a verdict against the reconstructed wind: KNOCKED — the breeze headed you, tacking was the right call. LIFTED — you were on the favored board and gave it away. Settle the argument before you reach the dock.

start windward mark TACK 2 · KNOCKED ✓ breeze headed you — right call TACK 3 · LIFTED you were on the paying board — hold it This beat: 4 KNOCKED · 2 LIFTED · 1 MIXED

Patent pending The technology behind SmartCoach — hindsight-fair analysis, live data retrieval, on-device verification, and per-tack shift scoring — is patent-pending.

Works with Vakaros Atlas 2

Atlas on the bow.

Vakaros Connect shows you a track and a speed graph. axiotrax reads the same race — natively, via the open VKX telemetry format — and turns it into a full debrief. One tap in the share sheet is the entire integration.

3 Marks. Heat map. VMG. Coach.
  • Exact gun time from the Atlas race timer — countdown, syncs and all
  • Your pinged PIN and BOAT line imports as truth — DTL and OCS analysis on the replay
  • Bare, zipped, or gzipped .vkx — all three share options just work
  • Your session names carry over, and logs going back years import cleanly

Race a J/70? Your fleet already runs Atlas. Every race you've ever recorded is one tap away from a full AI debrief.

axiotrax founder Clay Babcock worked at Vakaros, so this importer was built by someone who knows the format well. Vakaros and Atlas are trademarks of Vakaros, Inc. axiotrax is an independent product.

Live Instruments · Pro

It's all about
the wind.

Wind is your horsepower. You use it, seek it out, manage it — turn every shift to your advantage. axiotrax already uses next-level intelligence to infer wind, learn the conditions you race in, and build that context into every coaching conversation. It does a great job.

But what if it actually knew your wind — second by second? Everything would go to the next level.

Connect a wind source and axiotrax sees the live signal directly — wind speed, direction, and angle measured on your boat, not modelled from a weather grid. Your polars come to life, and every coaching insight is grounded in exactly what the wind was doing at that moment. There are two ways to feed it, from a full instrument network to a single wireless sensor on your mast.

This is coaching in the AI age.

  • True wind — measured on your boat, not modelled from a weather grid
  • Polars grounded in your actual conditions — not a generalisation
  • AI coaching that knows exactly what the wind was doing

Two ways to feed axiotrax your live wind

Your instrument network

NMEA 2000

Already have masthead wind instruments? Add a small NMEA 2000 Wi-Fi bridge like the Actisense W2K-2, and axiotrax reads your boat's true wind speed, direction, and angle straight off the network. Nothing to calibrate — it's already dialed in.

Calypso Ultrasonic

Wireless · new

No instruments? Mount a Calypso Ultrasonic wind sensor at the masthead. It's solar-powered with no moving parts to break, and it streams wind to axiotrax over Bluetooth — which fuses it with your GPS to ground every reading in true wind. Nothing to wire, nothing to power.

Calypso Ultrasonic Portable — solar-powered masthead wind sensor with no moving parts

Either way, the signal lands in the same place: live on your map, saved with every session, and in front of SmartCoach for every debrief.

Finish Line

Boat powered up. Trim dialed. A busy fleet all around you and the finish line dead ahead. axiotrax locks speed, compass, and VMG to every frame — so when you relive that approach, every number is exactly where it was. The kind of sailing worth remembering.

Crossing Fleets

You're on the upwind leg, mid-course — and another fleet is bearing down under full kite. axiotrax has the whole picture: your speed, your angle, exactly how the cross played out. The kind of moment that makes a great debrief even better.

SmartCourse powers the overlay. axiotrax knows which leg of the race your video is from — windward, leeward, reach — and updates the race leg indicator automatically as the footage plays. No manual tagging. No chapter markers. It just knows.
