Search for a tool or task, check its pricing, and open its official website. Freemium means a free plan with paid upgrades.

Free self-hosted UI · model costs
Chat with AI models in your own browser-based workspace.
Use the self-hosted UI with its required branding under the current license. There is no included paid-model allowance: cloud APIs, servers and storage can cost extra. Removing branding or qualifying enterprise uses may require a separate license; do not assume the current release is unrestricted BSD.

Free desktop app · separate cloud plans
Ask AI questions about your documents and files.
The local desktop app and self-hosted software have a free MIT-licensed option. Cloud hosting and selected external model APIs can charge separately. Local model use still requires your device resources; free software does not include every model provider.

Free Sandbox · paid cloud plans
Build AI chatbots and automated workflows.
Cloud Sandbox is free with limited credits and storage. The provider lists Professional at USD 590/workspace/year and Team at USD 1,590/workspace/year on annual billing, before applicable taxes. Community self-hosting uses your infrastructure; model API keys and paid features can add costs.

Free 1,000 credits/month · paid upgrades
Turn web pages into text and data for AI apps.
The hosted Free plan includes 1,000 credits each month. Hobby is USD 19/month billed monthly or USD 16/month billed annually for 5,000 monthly credits. Endpoint credit charges vary; optional paid-plan top-ups and extra usage can add charges.
