	Perplexity S	Adobe Firefly A	Symphony A
Tagline	AI search done right. Cited answers, not chat theater.	Commercially safe image gen, deeply integrated with Photoshop.	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	Research	Image	Agents
Pricing	Free + $20/mo Pro	Free + included with Creative Cloud	Free (open-source)
Best for	Replacing Google for any question where you want a cited answer in seconds.	Anyone in Creative Cloud. Brands that need copyright clarity.	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	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Trained on licensed content — commercially safe Generative Fill in Photoshop is incredible Native to Adobe ecosystem	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	Not a general chatbot Answers can be shallow on complex topics	Aesthetic ceiling below Midjourney Tied to Adobe subscription	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	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier inside Photoshop (Generative Fill). 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.)
