Tellama

Turn your Android phone into a private, Ollama-compatible AI server.
Run GGUF models on-device. Chat locally. Connect your PC, scripts, and agents through a small authenticated API.

Your phone. Your model. Your endpoint.

Tellama is more than another chat screen. It turns hardware you already own into a reusable local AI endpoint:

• Private by default: compatible GGUF models, chats, and long-term memory stay on your device.
• Useful beyond the phone: trusted computers and agents can call Ollama- and OpenAI-compatible routes over your Wi-Fi.
• Built for real devices: model guidance, measured memory and thermal status, resumable downloads, and safe model unloading protect limited mobile resources.
• Lightweight research agent: summarize or compare public HTTPS pages with persistent sources, then choose whether the result belongs in long-term memory.

Mac / PC / Agent ── Ollama or OpenAI API ──▶ Android phone ──▶ Local GGUF model

The Android app is commercially licensed and its complete source remains private. The working Python and JavaScript clients, examples, and compatibility tests in sdk/ are open source under Apache-2.0.

Quick start

Upgrading from v1.2.0 on Android 10: install a signed v1.2.1-or-later APK manually once from the release page. Android retains your Tellama data and models. In-app updates initiated by v1.2.1 and later use the physically qualified update path.

1. Install the latest APK.
2. In Models, download and select a model that fits the phone.
3. In Server, create an API key, choose Wi-Fi LAN, and start the server.
4. Export the values shown by Tellama:

export TELLAMA_URL="http://PHONE_IP:11434"export TELLAMA_API_KEY="tlm_..."

List the exact model IDs installed on the phone:

curl "$TELLAMA_URL/api/tags" \
-H "Authorization: Bearer $TELLAMA_API_KEY"

Call the Ollama-compatible streaming chat route:

curl "$TELLAMA_URL/api/chat" \
-H "Authorization: Bearer $TELLAMA_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "model": "MODEL_ID_FROM_API_TAGS", "messages": [{"role": "user", "content": "Hello from my Mac"}] }'

The response is newline-delimited JSON. OpenAI-style streaming is available at POST /v1/chat/completions using SSE. See the API compatibility reference for the exact supported routes and current limitations.

Open clients

No cloud account or package registry is required.

# Python 3.10+, standard library only
TELLAMA_URL="$TELLAMA_URL" TELLAMA_API_KEY="$TELLAMA_API_KEY" \
python3 sdk/python/example.py
# JavaScript, Node.js 18+
TELLAMA_URL="$TELLAMA_URL" TELLAMA_API_KEY="$TELLAMA_API_KEY" \
node sdk/javascript/example.mjs

The clients support model discovery, bounded generation options, Ollama NDJSON chat streaming, OpenAI SSE chat streaming, timeouts, and structured HTTP or stream errors. Run their contract suite with:

What the Android app includes

• Phone-aware GGUF model catalog, import, selection, deletion, and per-model generation controls
• Resumable large-model downloads with storage reserve, trusted mirrors, SHA-256 checks, and GGUF validation
• Safe loaded-model deletion that stops active serving, unloads native memory, and then reclaims storage
• Memory-aware model replacement that unloads the resident runtime before recalculating available RAM, reports selected/loading/ready states truthfully, and rolls back both selection and runtime after a failed load
• Local streaming chat with timestamps, slash commands, voice input, and user-controlled long-term memory
• User-initiated HTTPS page summaries and comparisons with persistent sources and explicit approval before saving a result to memory
• Workspace dashboard for serving readiness, measured chat speed, RAM, storage, battery, and thermal guidance
• Authenticated Wi-Fi LAN serving with one-time API keys, permission scopes, rate limiting, foreground status, and automatic stop on Wi-Fi loss
• Non-blocking startup update reminders plus in-app download with SHA-256, package, version, and signing-certificate verification
• Grouped commercial-grade settings with an app-wide, persistent 85%–130% text-size control
• Hardened generation, model preflight, encrypted-data recovery, downloads, memory consent, and API reliability for friend testing
• 15-language resources with TalkBack, large-text, landscape, tablet-width, and RTL layout support

Security boundary

• LAN mode is off until the user starts it.
• LAN requests require Authorization: Bearer <key>.
• Full API keys are displayed once; Tellama stores their SHA-256 hashes.
• Changing or losing Wi-Fi automatically stops the LAN server.
• Do not expose port 11434 to the public internet or forward it from a router.
• External API models have different privacy and billing conditions from Tellama's local server.
• Web research makes direct HTTPS requests to the URLs you provide. Page text stays on the device when a local model is selected; with an external API model, that text is sent to the configured provider after an in-app warning.

Report security issues through SECURITY.md. Feature requests and SDK contributions are welcome; see CONTRIBUTING.md and the roadmap.
