Free AI · no key, no sign-up

Your owncalisthenics& nutrition coach.

A coach that reads your live data — food, water, today's session, the joints that hurt — and answers in real time, streamed word by word. No API key to paste: the free AI is built in. It photographs your plate, counts the macros, and writes your program from your gear and level.

What makes it different

Your plan, your logs, your food data — on your phone.

The program, the logs, the food database and the injury logic all live on the device. Only the coach’s words travel: one streamed request, and the rule engine covers the times it can’t.

A coach that streams in words

Replies stream token by token from the free built-in engine — no key, no sign-up — or from any provider you connect instead. The answer starts appearing immediately: no model to download, no 100 MB installer, no warm-up.

  • ~4 MB APK, down from 115 MB
  • Word-by-word streaming in the chat
  • Built-in rules answer when offline

Injury-aware coaching

Say “my wrists hurt” and the model audits the session, names the movements that load the joint and swaps them for joint-friendly versions — then rewrites your plan with one tap.

  • Wrist → knuckle push-ups, forearm planks
  • Knee → bridges, box squats, no impact
  • Every change is reversible

Zero-key AI, your choice of brain

It works the moment it installs: the keyless Puter transport streams the coach with no key and no sign-up. Prefer your own model? OpenAI, Gemini, Groq, OpenRouter, Anthropic or a self-hosted Ollama/vLLM endpoint all take over from one screen.

  • Free to use with no API key
  • Any OpenAI-compatible endpoint
  • Rule engine answers if the AI is unreachable

Indian meal photo analyser

Photograph the plate — 2 rotis with ghee, tadka dal, paneer butter masala, dosa, idli-sambar, chole bhature, biryani, curd rice — and the vision model names the dish, estimates the portion in Indian measures and splits the macros. One tap logs it.

  • Dish + portion in katori / roti / plate
  • Calories, protein, carbs and fat
  • “Log to Daily Nutrition” in one tap

Calisthenics & meal vision

A 60-day phased bodyweight program plus photo or voice food logging. Snap the thali, say “two eggs and curd”, and the macros land in the right slot.

  • 60 days, 70+ movements, zero equipment
  • Voice → macros in one sentence
  • Indian food database built in
Streaming AI engine

Answers that arrive as they are written.

The coach runs on the free keyless engine — or the provider you connect — and streams every reply into the chat token by token, so you read the first line while the rest is still being written. No model file, no warm-up, no spinner — and the deterministic rule engine still answers when the network does not.

Token-by-token streaming

Replies appear as they are generated — never a frozen “thinking…” for two minutes.

Voice in, answer out

Speech is transcribed live on the device, then sent as one clean sentence.

Honest about privacy

Your prompt or meal photo goes to the model that answers — and nowhere else. Logs, weights and meals stay on your phone.

Injury-aware

Tell it what hurts. It fixes the session.

The coach matches what you said to the movements in today's plan, checks each one against the joint it loads, and proposes concrete replacements. You approve once; the plan changes everywhere.

AI program

Your plan, written for you.

Pick a goal — strength, fat loss, skills or endurance — and the coach writes the whole rotation around your level, your equipment and the joints that complain. Every movement is matched to a real exercise with its own form guide, then loaded into the guided player.

Train with a coach that answers

The free AI writes your program, the guided player runs it, and the coach adapts it when something hurts — or when you photograph your lunch.

Calisthenics & food

Log lunch in one sentence.

Say “two boiled eggs, a bowl of rice and curd” — the words are transcribed on-device, parsed against an Indian food database, and turned into calories and macros you can nudge before saving. Or photograph the thali: the vision model names the dish, estimates the portion in rotis and katoris, splits the macros and offers one-tap logging.

Questions

The honest answers.

Nobody's key is needed. FlexPulse ships with the keyless Puter transport, so the coach, the injury fixes, the program writer and the meal-photo analyser all work on a fresh install with no key and no sign-up. If you would rather use your own model, Settings → AI provider takes any provider (OpenAI, Gemini, Groq, OpenRouter, Anthropic or a self-hosted Ollama/vLLM), a base URL, a key and a model name — and everything switches to it.
