Praex

Freemium

Open-source AI coding copartner with its own Velox, Faber and Lucia models, available in terminal, mobile and web.

Own Model Family: Velox II, Faber II and Lucia II are tuned and served by Praex on its own infrastructure, sized from quick edits to frontier-scale problems.
Terminal CLI: Install with a one-line script and let the agent read files, run commands, edit code and verify tests directly in your terminal.
Cross-Device Sessions: Start a task in the terminal, steer it from your phone and review it on the web with the same agent, memory and session.
Bring Your Own Keys: Run Praex on any model with your own API keys or hardware at no extra cost.
Open-Source Core: The CLI is an MIT-licensed fork of opencode, so the agent harness can be inspected and modified.
No Sign-Up Chat: Start chatting on the web with the free Velox II model without creating an account.

Fixing Failing Builds: Hand the agent a broken deploy and let it read configs, run tests and patch source until tests pass.
Everyday Quick Edits: Use the free Velox II model for instant answers and small code changes in the terminal.
Deep Reasoning Tasks: Escalate to Faber II on Pro for complex coding and multi-step reasoning.
Mobile Task Steering: Kick off a refactor at your desk and monitor or redirect it from your phone.
Self-Hosted Workflows: Point the CLI at your own models or keys to keep code on infrastructure you control.

Free

Free, open-source voice-to-text app for dictation, AI assistant, and voice writing across any app on Windows, macOS, and Linux.

Cross-App Dictation: Press a hotkey (Left Ctrl + Left Super by default) and speak — your words type straight into any app: email, editor, or chat, live as you talk.
Hey Flow Assistant: Say 'Hey Flow' to reply to a message, write an email, or draft a prompt without touching the keyboard; trigger name is renamable.
Live Translation: Speak Spanish, Hindi, French, Japanese, or any language and get clean English typed at your cursor, running fully on-device.
AI Cleanup: Strips 'um's and false starts, fixes grammar, and matches a chosen tone (Professional, Friendly, Concise, or custom) so speech reads polished.
Screen-Aware Answers: One hotkey summons a floating assistant that can look at your screen and answer about the error, chart, or email in front of you.
Private Memory & Profiles: Separate profiles per part of your day; remembers how you like to work locally without sending data off-device.
Cross-Platform Downloads: Ships as a Windows installer, macOS build (one Terminal command on first install), and .deb for Ubuntu and Debian.

Faster Writing: Developers, writers, and support agents dictate at 150+ WPM instead of typing at 45 WPM.
Multilingual Reply: Speak in your native language and reply in polished English without switching keyboards or translators.
Private On-Device Voice Work: Users who don't want their voice sent to a cloud get local dictation and translation.
Voice-Driven Prompts: Draft LLM prompts, emails, or Slack replies by voice inside any editor or chat app.
Screen Q&A: Ask the assistant about the specific error or chart on screen without pasting it in manually.
