What platforms does OnVerb support?

OnVerb is available on Web App.

What are the limitations of OnVerb?

The flagship models (Claude Opus, Gemini 2.5 Pro, GPT 5.5 and others) require a subscription, so the headline model list is partly gated. Free tier is capped at 50 chat credits per month, which will not carry regular daily use. Token and credit billing makes costs harder to predict than a flat per-seat subscription.

What is OnVerb?

OnVerb is an AI chat bot tool. A multi-model AI chat workspace where GPT, Claude and Gemini sit behind one interface, organized around a shared library of system prompts, document context and team collaboration with token-based billing.

OnVerb is a multi-model AI chat platform that puts OpenAI, Anthropic and Google models behind a single interface. Instead of keeping separate subscriptions to ChatGPT, Claude and Gemini, a user picks a model per conversation and switches when one handles a task better than another. The model roster spans the cheaper, faster tiers (GPT-5 Mini, GPT-5 Nano, Claude 4.5 Haiku, Gemini 2.5 Flash Lite) up to flagship options such as Claude Opus, Gemini 2.5 Pro and GPT 5.5, several of which sit behind the paid plan. Context windows range from 200,000 tokens on the Claude models to 400,000 on OpenAI and 1,000,000 on Gemini. The feature that defines the product is the system prompt library. A system prompt holds the instructions, tone rules, examples and background that shape how the AI answers, so a generic assistant becomes a brand-voice copywriter or a research assistant restricted to trusted sources. Users build prompts in a dashboard, attach document context, test them against several models, then save and share them. Updating one attached file refreshes every prompt that depends on it, and global rules apply consistent guidelines across all interactions. An integrated document editor, bulk CSV processing, encrypted prompt storage (AES-256) and shared chats round out the workspace, and teams can invite unlimited members without per-seat charges. It suits teams that already use AI daily and have outgrown ad hoc prompting: marketing groups enforcing a voice guide, consultancies handling client material, writers and analysts who reuse the same instructions repeatedly. Billing is token or credit based rather than per seat, so cost tracks usage. Compared with individual chatbot subscriptions, OnVerb's value is consolidation and prompt reuse; compared with heavier enterprise AI platforms, it is lighter and centered on chat plus documents rather than deep application building. Lone casual users may find the free credit allowance limiting, and the product is not built for image or video generation.

How do you use OnVerb?

1Create a free account
Sign up from the signup page. No credit card is required and the free tier includes 50 chat credits per month with access to select models.
2Build your first system prompt
Open System Prompts in the dashboard and choose New Prompt. Write the instructions, examples and tone rules that define the assistant you want, such as a brand-voice writer.
3Attach document context
Upload reference files to the prompt so answers draw on your own material. Editing that file later updates every prompt using it rather than each prompt individually.
4Test across models
Run the prompt against GPT, Claude and Gemini in turn and compare outputs before saving it to the library. Pick the model you will default to for that task.
5Draft in the document editor
Create or open a document, apply the saved prompt, and refine the text with AI assistance inside the editor rather than copying between tabs.
6Share with your team
Invite colleagues and share prompts, documents and chats so everyone works from the same knowledge base. Team seats are not charged individually.
