The top picks

  • Gemini — an unusually generous free tier, especially for image generation.
  • ChatGPT — capable free tier (with ads in the US).
  • DeepSeek — strong free coding and maths — but data is stored in China.
  • Meta AI — free inside WhatsApp and Instagram, no install.
  • Stable Diffusion — free and open-weight to self-host (technical).
  • Adobe Firefly — 25 free credits/mo, no watermark, commercial use allowed.
  • Gamma — free decks from a prompt (with Gamma branding).

How to choose

Free tiers cover most casual use. Watch the catches: usage caps, ads (ChatGPT free/Go in the US), non-commercial or watermarked creative outputs, public outputs on some image tools, and the chance your inputs train the model. For commercial creative work, a paid licence usually matters. DeepSeek stores data in China — keep sensitive inputs out.

If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
