Chat assistants · alternatives
Dvina's allowances are the usual sticking point. Usage is given as relative multipliers refreshed in 5-hour windows with a weekly ceiling, not as stated amounts, so you cannot easily predict how far a plan goes. Pro is $100 per user per month, Max is shown as $100 with $200 struck through, and Enterprise needs a sales call. The free plan has limited daily usage. Prices checked on 2026-10-02.
ChatGPT starts at Plus, $20 per user per month, and has a free option. Claude starts at Pro, also $20 per user per month, with a free option. Microsoft Copilot starts at Microsoft 365 Personal, $9.99 per month, the lowest entry price of the three and also with a free option. All three start well below Dvina's $100 tiers, though we have not compared their usage limits.
"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.
Taken from the documented limitations in our Dvina profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Dvina (this page) | $18/mo (Plus) | Yes | Web, Desktop, Mobile | Usage allowances are relative multipliers refreshed in 5-hour windows with a weekly ceiling, not stated amounts, and Max pricing shows a struck-through discount. |
| 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. |
| Microsoft Copilot | $9.99/mo (Microsoft 365 Personal) | Yes | Web, Desktop, Mobile | Free-tier usage limits are not quantified; higher usage requires a paid Microsoft 365 plan. |
