Strengths	+ Fully autonomous cloud sessions that run tasks end to end without local setup + Access to multiple frontier model families plus Cognition's own SWE models + Quota-based plans scale from a free tier to high-usage Max and Teams tiers	+ Generous free tier with 15 daily tasks and no local setup required + Asynchronous plan-approve-PR workflow suited to delegating routine fixes and chores + Paid capacity comes bundled with existing Google AI Pro and Ultra subscriptions
Tradeoffs	− Works best on well-scoped tasks; practitioners report mixed results on ambiguous or large refactors − Quota allowances can deplete quickly on long autonomous runs, pushing users to API-priced top-ups − Closed source with less interactive steering than pair-programming style CLI agents	− GitHub-only repository integration; no support for other forges − Paid tiers are currently limited to personal Gmail accounts, with business upgrade paths still pending − Less interactive mid-task steering than terminal-based pair-programming agents
