SageGate

Stop paying $20/month for each AI subscription. SageGate connects you directly to your AI providers through one beautiful app — and you only pay for what you actually use.

HOW IT WORKS
Connect your own API keys and pay per conversation instead of $20/month per service. Many users spend under $5/month for heavier usage than any single subscription offers. SageGate shows you exactly what each message costs — no surprises, no waste.

YOUR DATA STAYS YOURS
The free app has no accounts and no sign-ups, and your chats never pass through our servers. Your conversations live only on your device or your personal iCloud. Your API keys are stored in the iOS Keychain, and you can lock the whole app behind Face ID. Chats run over Apple's encrypted networking (TLS) straight to the provider you chose — SageGate is never in the connection, so we can't read or decode them. We never see your messages. Period.

AI PROVIDERS, DOZENS OF MODELS IN ONE PLACE
Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM, Doubao, ERNIE, HunYuan, MiniMax, Spark and more. Ask ChatGPT for writing, switch to Claude for code, then check with Gemini — all in one thread.

ONE KNOWLEDGE BASE ACROSS EVERY MODEL (SAGEGATE CLOUD — OPTIONAL)
Your documents shouldn't be trapped inside one AI. SageGate Cloud gives you your own private vector database that every model can search — pulling back only what's relevant. Switch models and they all reach the same knowledge; nothing is siloed. Upload from your iPhone, or from any browser at portal.sagegate.ai. Upgrade only if you want the shared cloud brain. Still no accounts:
- T4 Managed Cloud ($19.99/mo) — we host your encrypted vault; zero setup.
- T3 Private Cloud ($5.99/mo) — your documents live in your own AWS. Our pipeline processes your documents during ingestion and search, and nothing is retained.
- T2 Self-Host ($1.99/mo) — your AWS only, extracted on your device; we never touch a byte.
The app itself stays completely free — and giving back is built in: 10% of every App Store purchase goes to 501(c)(3) animal-welfare nonprofits (records published at sagegate.ai).

SEE WHAT YOU SPEND
Every message shows exactly how many tokens were used and what it cost. The Cost Dashboard breaks down tokens and spending by provider and model. Think of it as a budgeting app for your AI usage.

AUTOMATE YOUR BUSYWORK
Set up Skills — reusable prompt templates for tasks you do every day, like summarizing emails or translating documents. Schedule tasks to run automatically when you open the app.

BRING YOUR OWN FILES
Drop PDFs, Word docs, spreadsheets, or presentations into the app. SageGate reads them on-device and lets any AI answer questions about them. Stay fully local for free, or add SageGate Cloud to index them for search. Drag files into iCloud Drive from your Mac and they appear instantly.

CUBICLES (BETA)
Give each project its own workspace with its own chats, documents, instructions, and model; chats inside a Cubicle see only that Cubicle's material. Cubicles use models that pass our tool test.

REMEMBER WHAT MATTERS
Tap "Save to Memory" on any helpful AI response. That knowledge carries across every future conversation with every provider — your personal AI memory that grows with you.

RUN AI ON YOUR OWN COMPUTER
Connect to a model server on your Mac or network, such as LM Studio or llama.cpp, for work that should never touch the internet.

WORKS IN YOUR LANGUAGE
Full support for 13 languages: English, Simplified & Traditional Chinese, Japanese, Korean, German, Spanish, French, Italian, Portuguese, Russian, Hindi, and Indonesian.

ADDITIONAL FEATURES
- Watch AI models "think" in real-time with visible reasoning streams
- Export any AI response as a formatted PDF with one tap
- Organize chats with folders, pins, search, and smart sorting
- Full VoiceOver accessibility support, light & dark mode
