Chat assistants · alternatives
Cumora is an invite-only preview, so the first obstacle is access: you join a waitlist and wait for approval. Sign-in is only via Google or GitHub. No pricing is published beyond free during preview, so post-preview cost is unknown, and the iOS app is announced as shipping next but is not yet available, which leaves no mobile access.
ChatGPT is open now: Plus is $20 per month, with a free plan, and it covers writing, research and analysis. Claude offers a free plan, and its Pro plan is $20 per month. Character.AI lets you chat with user-created AI characters, free to start, with no price captured in our pack. Notion AI puts AI inside a team workspace; Plus is $12 per member per month. None of the four is described as a team chat where agents start conversations.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.

| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Cumora (this page) | Not published | Yes | Web, Desktop | Cumora is an invite-only preview with no published pricing beyond free during preview, and sign-in is only via Google or GitHub. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | All plans have usage limits that reset on a schedule; the paid chat subscription does not include API access, which is billed separately per token. |
| Character.AI | Not published | Yes | Web, Mobile | No official pricing page could be read, so paid-tier prices and limits are unverified. |
| Notion AI | $12/mo (Plus) | Yes | Web, Desktop, Mobile | Full AI needs Business or Enterprise, and even there a rolling six-hour and monthly usage allowance applies; premium models, Custom Agents and Workers consume separately purchased Notion credits. |
