Which one is for you
Pick ChatLLM if
- Fits if you want many frontier models without a subscription to each lab
- Works for teams that want chat, an agent and app building on one bill
Look elsewhere if
- Not for you if you want to try before you pay, as there's no free plan or free trial
- Tight if you want the agent on Basic, which stops at 3 tasks of limited complexity and 3 Studio conversations
- Skip it if you expect refunds for poor results, since Abacus.AI says it gives none based on output or performance
- Watch out: heavy models, images, video and agent tasks burn through the 20,000 monthly credits faster
- Pricey if you're a team, as it's $10 for every user, and $20 each with Pro
Pick Writingmate if
- Fits if you want to compare answers from several models in one place
- Works for people who want chat, images and video under one bill
Look elsewhere if
- Skip it if you want a free plan, as the page lists paid plans and a 3-day trial only
- Tight if you chat a lot: Pro is about 200 top-model messages or 100 images a month
- Pricey if you pay monthly, at $29.99 against $19.99 on yearly billing
- Watch out: the trial needs a payment method and renews on its own unless you cancel in Profile Settings
- Watch out: message and image counts per plan are estimates, and prices exclude tax
How we grade them
| 2.4GPAChatLLMFair | 2.4GPAWritingmateFair | |
|---|---|---|
| Value for money | CBasic is $10 a user a month, the middle of this category, and it covers every chat, image and video model with 20,000 credits. The agent stops at 3 limited tasks, though, and lifting that means Pro at $20. | CPro is $19.99 a month yearly, $29.99 monthly, for 800 credits. That is above the $18 where the dearer quarter starts and just under the dearest tenth at $20. |
| Free plan and trial | FNothing is free. No free plan and no free trial, so the first look costs money. The nearest thing to a taster is a first month of Basic at $7 instead of $10, and that month brings 14,000 credits rather than 20,000. | DThe only way in is a 3-day trial that needs a payment method. It starts the chosen plan automatically unless you cancel, and there is no free plan. |
| Features | BMore than 100 models with RouteLLM picking one for you, an agent that builds apps, slides and reports, image and video generation, file and data analysis, web search and a team workspace. That's the job covered. | BMany models, side-by-side comparison, images, video, agents, files, web search and an API, all in one account. Nothing in the listing is missing from the job, though credits limit use. |
| Ease of use | A4.9 from about 3,600 App Store ratings. Leave the picker on Auto and it chooses the model, so you needn't know which is which. Credits are the thing to watch, as heavy models, images and video eat them faster. | BA browser chat with nothing to set up. No store rating is on record. |
| Platforms and integrations | BWeb, iPhone and Android with a voice mode, plus a Chrome extension, and it connects to Slack, Teams, Google Drive, SharePoint, Confluence, Salesforce and Gmail, with an API that routes between models. No desktop app in the platform list. | BWeb only, with an OpenAI-compatible API and apps through MCP. |
| Best for | many AI models on one $10 subscription | several chat models behind one subscription |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
