A chat UI is easy, but Gemini's model access, Google ecosystem integration, multimodality, storage tie-ins, and platform distribution are not solo-buildable.

the prompt
Build me a personal chat client on the Gemini API to replace my Google AI Pro
subscription with per-token billing. Requirements:

- A local web app: Node + Express + better-sqlite3, one page, binds to
  localhost.
- Gemini API key in .env, with optional Claude and OpenAI keys too; a model
  picker per conversation.
- Streaming responses with Markdown and code-block rendering; history in SQLite
  with FTS5 search across old conversations.
- Upload PDFs and images and pass them through to models that accept them.
- System-prompt presets as .md files in ./prompts/, selectable per chat.
- Export any conversation to a Markdown file.
- No accounts, no telemetry; history stays on my machine, only prompts go to
  the APIs.
- Out of scope: Gmail, Docs, and Drive integrations, and mobile apps. Do not
  build Google Workspace OAuth; that ecosystem tie-in is the subscription.
- README: where to create each API key, a rough cost table per model, and state
  that per-token billing can land above or below $20/month depending on use,
  the model itself is only rentable.

why people still pay

They pay for model access and Google-native placement, not because chat UIs are hard.

questions
Can AI replace Google Gemini?

Not really. Google Gemini's value is not the code — . See the honest breakdown above.

How much does Google Gemini cost?

Google Gemini costs about $19.99/month (Google AI Pro, checked 2026-07-30), which is $239.88 per year.

What do I lose by replacing Google Gemini?

Honestly: frontier models; Google app integrations; mobile/native distribution; multimodal stack; reliability. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Google Gemini?

Yes — Open WebUI (Open-source self-hosted chat UI for model APIs and local models.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
