## Open WebUI

Open WebUI is an open-source, self-hosted interface for working with AI models. Instead of renting access to a single vendor's chatbot, you run the interface on your own hardware or cloud tenancy, then connect whatever models you want: local runtimes such as Ollama, OpenAI-compatible endpoints, Anthropic, or a mix of local and remote. Everything a team produces — conversations, prompts, models, skills and tools — stays in an environment you administer.

The platform has grown well beyond a chat window. Retrieval-augmented generation, web search, document understanding, voice input and output, and vision are built in, and Python tools, functions and pipelines let developers script custom behaviour and share it. On the operations side it offers enterprise features such as SSO, role-based access control, audit logs, data residency options, and on-premises, hybrid or fully air-gapped deployment for regulated environments. White-labeling and custom branding are also available for organizations that want their own look.

Open WebUI is distributed free of charge under an open-source license and can be installed with a single pip or Docker command, with no account required to get running. A separate enterprise offering is available for organizations that want commercial support, compliance guarantees and managed rollout help, which is quoted on contact. A large community maintains a public hub of prompts, models, tools and functions, so much of what teams need is already shared and ready to install.

**Pricing & Plans:** The core platform is free and open source, installable via pip or Docker with no account required. An enterprise tier with support, compliance and deployment assistance is quoted on contact.

- **Any Model, Any Endpoint:** Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
- **Retrieval and Search Built In:** RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
- **Python Tools, Functions and Pipelines:** Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
- **Enterprise Controls:** SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
- **Community Hub:** Browse and install prompts, models, skills and tools contributed by hundreds of thousands of community members.

**Strengths:** Free and open source with no account needed to install; Works with local and cloud models through a single interface; Strong privacy posture: your data and models stay on your infrastructure; Extensive enterprise features including SSO, RBAC and audit logs

**Limitations:** Self-hosting requires you to handle servers, updates and backups; Some enterprise capabilities and support sit behind a paid, quote-based tier; Feature depth means a learning curve for non-technical administrators; Local model performance depends heavily on your own hardware

## OsmO

OsmO is an AI phone assistant that sits behind your existing phone number and deals with the calls you would rather not take. It answers unknown callers, asks who is calling and why, silences robocall and scam traffic, and texts you a transcript and summary of anything that mattered. Because it works through conditional call forwarding on the number you already have, there is no SIM swap and no second line to pay for.

The product covers both directions of traffic. On inbound calls you define rules that decide what happens: family and known contacts ring straight through, unknown numbers get a chosen assistant character, telemarketers are silenced, and after-hours calls go to a message. OsmO can also clone your voice from roughly fifteen seconds of speech so callers hear you rather than a stranger. For small businesses, the assistant reads your website, PDFs, Google Docs and Sheets, FAQs, service areas and Maps listing to answer customer questions, check availability and book jobs during the call, then confirm the slot in Google Calendar or Calendly.

OsmO is available as a free download for iPhone and Android and supports the United States, United Kingdom, Australia, India and Canada, speaking English, Spanish and Hindi with French and German listed as coming soon. A free 7-day trial is offered; after that Android users choose between Basic and Premium, while iPhone users subscribe to OsmO Pro, with Apple and Google showing the localised price before purchase. Calls are encrypted in transit and you can review, export or delete your transcripts and recordings.

**Pricing & Plans:** Free to download with a free 7-day trial. After the trial, US pricing starts around US$7.99/month on Android (Basic and Premium tiers) and about US$9.99/month for OsmO Pro on iPhone, with localised prices shown by the App Store or Google Play at purchase time.

- **Spam screening and call answering:** Unknown callers are screened automatically: spam is silenced while legitimate messages, bookings and urgent calls are passed through to you.
- **Custom call-handling rules:** Set rules once — let family straight through, have a chosen character handle unknown numbers, silence telemarketers, and send after-hours calls to voicemail-style messages.
- **Knowledge base for businesses:** Feed the assistant your website, PDFs, Google Docs or Sheets, FAQs and Google Maps listing so it answers callers from your own materials rather than guessing.
- **Voice cloning and character voices:** Read a short line aloud and OsmO clones your voice so calls are answered as you, using either your voice or one of the studio and character voices.
- **Outbound calls, bookings and summaries:** OsmO can call out on your behalf, check availability against Google Calendar or Calendly, book slots during the call, and text you a transcript and summary seconds later.

**Strengths:** Runs on your existing number, with no SIM swap or extra line needed; Handles both inbound screening and outbound calling and booking; Voice cloning and character voices make calls sound natural and personal; Answers business questions from your own website, documents and FAQs

**Limitations:** Relies on carrier conditional call forwarding, and forwarded minutes may be billed by your carrier; Supported in only five countries; iPhone and Android use different plan names, so features can differ by platform; Screening can occasionally let an important unknown call slip past, so you still need to check messages
