No free plan. As of 2026-08-09, browsing the official website copy.ai/prices, there are only two tabs: Self-Serve and Enterprise. Self-Serve has only one plan, Chat, at US$29/month, and Enterprise is quote-based. Neither tab has a free plan card. The previous free plan of 2,000 words per month is no longer on the current webpage.
Free plan US$0, "Free forever". Included credits are "1,000 one-time", i.e. a single 1,000-credit grant (not monthly); the Weekly refresh column shows "–", meaning no weekly top-up (only paid plans get Pro +2,000/week and Max +4,000/week, reset every 7 days and not accumulated). 1 workspace, cannot invite teammates. Concurrent executions capped at 10; rate limits of 50 sync runs/min, 200 async runs/min and 30 API endpoint calls/min; execution timeouts of 5 minutes (sync) and 90 minutes (async); storage of 5GB of files, up to 5 tables, up to 50,000 rows per table, 30 days log retention. Not included on the free plan: Sim Mailer (Inbox), KB Live Sync, Sandboxes, Slack Connect, Access Control, SSO, SOC2 Compliance, Self Hosting, Dedicated Support. When credits run out, the official docs state "usage is capped at your plan's included credits and runs will stop" (runs stop by default; paid plans can enable on-demand overage at US$0.005/credit). 1 credit = US$0.005 (docs). The source conflict recorded on 2026-08-09 ("pricing page monthly vs docs one-time") is resolved: on 2026-09-16 both the pricing page and docs.sim.ai/platform/costs show 1,000 one-time / Pro 6,000 per month / Max 25,000 per month. Sim is an open-source project. (Read directly from sim.ai/pricing and docs via playwright on 2026-09-16)
Cheapest paid plan: US$25 / user / mo（5 user ≈ US$125/mo）
The official site's 'Self-Service' tab has only one plan: US$9/month (the page explicitly says Billed monthly), including 5 seats, unlimited words in Chat, unlimited Chat projects, and access to OpenAI/Anthropic/Gemini models; switching to the annual-billing page shows a 20% savings (the official site does not display the total annual amount)
Enterprise
Official quote (upon inquiry)
The official site's "Enterprise" tab: no public pricing, only a "Get a custom demo" button; includes guided onboarding, API access and batch workflows, 20+ technical integrations, unlimited custom workflows, a dedicated customer team, and enterprise-grade security.
