Compare AI tools

	Skye A	Claude Code S	Google Veo A	Symphony A
Tagline	An agentic iPhone home screen that replaces your static icon grid with AI widgets that proactively surface health, calendar, finance, and local context — without you having to open a single app.	Anthropic's CLI agent. Opus-powered, operates on your repo directly.	Google's video model. Baked into Gemini + YouTube Shorts.	OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out.
Category	Agents	Coding	Video	Agents
Pricing	Waitlist / Beta (pricing not yet disclosed)	Part of Claude Pro/Max/Team plans	Included with Gemini Advanced $20/mo + YouTube creator tools	Free (open-source)
Best for	iPhone power users who are frustrated that Siri is still reactive and want their home screen to actually anticipate their day.	Developers who want an agent, not autocomplete. Large refactors, tests, docs.	Gemini Advanced users, YouTube Shorts creators.	Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale.
Strengths	Ambient, proactive intelligence delivered via native iOS widgets — no app-switching required Cross-domain context: health, calendar, email, finances, and local recommendations in one layer Works within iOS permission model (no jailbreak or sideloading), making App Store approval plausible Strong pre-launch signal: 25k+ waitlist and backing from a16z, True Ventures, and SV Angel	Runs locally, edits your actual files Strong on large codebases with 1M context Great at multi-step tasks	Included with Gemini Advanced YouTube Shorts native integration Strong prompt understanding	Fully autonomous ticket-to-PR pipeline: every open Linear issue gets its own isolated Codex agent without manual supervision Fault-tolerant Elixir/OTP architecture automatically restarts crashed agents and manages hundreds of concurrent runs WORKFLOW.md keeps all orchestration policy version-controlled inside the repo, so agent behavior is reproducible and reviewable like code Proven internal results: OpenAI reported a 500% increase in landed PRs on some teams within three weeks Open spec encourages community re-implementations in any language, not just Elixir
Weaknesses	Still pre-launch / beta — zero proven track record and no public pricing yet iPhone-only by design, which immediately locks out half the smartphone market Battery drain and privacy concerns from constant ambient context scanning are real and unresolved	Terminal-based — learning curve Can't be used without Claude subscription	Still catching up on quality vs Kling/Runway Less control than pros need	Currently only supports Linear as an issue tracker — GitHub Issues and Jira integrations are not yet official Only OpenAI Codex is officially supported as the agent runtime; other model integrations are community-contributed and incomplete Self-hosted, Elixir-dependent engineering preview with no built-in sandboxing — not suitable for untrusted or production environments out of the box
Kai's verdict	The concept is genuinely compelling — turning the home screen into a living AI layer is a smarter bet than yet another chat interface — but this is vaporware until it ships publicly and we see whether Apple's sandbox lets it breathe. (Verdict pending Phi's full review.)	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier if you already pay Gemini. B-tier standalone.	Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.)
