AI-Softphone: The Free Desktop App That Prompts, Records, and Writes Up Calls

AI-Softphone is a desktop app that turns every call and meeting into a transcript, a live assistant, and a finished write-up, without a per-seat subscription attached to any of it. It's free and open source under GPL v2, and it unifies three capture paths, SIP calls on any IP PBX, meetings in Zoom, Teams, or Meet, and imported recordings, into one searchable library, then adds a live prompter that shows subtitles, live translation, and suggested next lines while the call is still happening. If your day runs through a mix of calls and meetings, this is built to sit underneath all of it.

One Library for Calls, Meetings, and Imports

Most call-recording tools solve one input at a time: a SIP recorder for phone calls, a separate bot for Zoom or Teams, a third tool for files someone hands you after the fact. AI-Softphone treats all three as the same problem. Calls placed or received through its built-in SIP softphone, which connects to any SIP account or IP PBX you already have, meetings running in Zoom, Microsoft Teams, Google Meet, or any other app on your computer, and recordings you import afterward all land in one library. Every conversation is recorded two-channel, so each side of the call is kept separate, with waveform playback, automatic cleanup rules, and a consent method you choose yourself, a spoken announcement, a tone, a manual confirmation, or none at all. Transcription is speaker-separated and time-synced, searchable across your whole history, and exportable as plain text or subtitles. For anyone whose day is genuinely split across phone calls, video meetings, and the occasional recording someone emails over, that's one place to search instead of three.

The Live Prompter: Help During the Call, Not Just a Transcript After

The feature that separates AI-Softphone from a typical recording-and-transcription tool is that it does something useful while the conversation is still happening. The live prompter overlays real-time subtitles, translates what the other person is saying line by line, and suggests what to say next, driven by instructions you write yourself. Four ready-made assistants ship out of the box: subtitles, translation, call-objection handling, and interview help, plus a practice mode that replays an old recording so you can rehearse against it. For sales calls where an objection needs a fast, well-considered answer, or interviews conducted in a second language, having the prompt appear during the conversation rather than in a post-call summary is the practical difference between a transcription tool and a live assistant.

Prompt Studio and the Write-Up Engine

After the call ends, AI-Softphone writes it up automatically: a summary, action items, names and numbers mentioned, categorisation and tags, red-flag alerts, and a sales or support score measured against criteria you define. A per-conversation Q&A box lets you ask follow-up questions about anything discussed, and translation is available on the write-up itself. All of this runs through Prompt Studio, 11 ready-made prompts that are editable in plain language, with a run order and conditions you control. That's a meaningfully different model from tools that hard-code their output format: if your team scores calls differently than the default, or wants a red-flag category specific to your industry, the prompt is yours to rewrite rather than a fixed field you work around.

Local or Cloud AI, Your Choice, With Cost Controls

AI-Softphone doesn't lock you into one model provider. It runs on local models through Ollama, vLLM, or Llama for teams that want conversations processed without any data leaving the machine, or on cloud services including OpenAI, Claude, Gemini, Grok, Mistral, DeepSeek, and Groq for teams that prefer a hosted model's quality. Per-call cost is tracked automatically, and a monthly spending ceiling keeps cloud usage from running away. That flexibility extends to how the app fits into an existing stack: click-to-dial from phone number links, webhooks for call events, and a localhost-only REST API make it straightforward to wire into a CRM or internal tool without AI-Softphone needing to know what that other system is. Business-phone basics, multiple accounts, simultaneous calls, hold, mute, transfer, and conferencing, are all included alongside the AI layer.

Who Gets the Most Value from AI-Softphone

The clearest fit is sales, support, and interview-heavy teams whose day genuinely runs through a mix of phone calls and video meetings and who want every one of them captured, transcribed, and summarised without paying a per-seat fee for the privilege. The ability to choose a local model also makes it a strong fit for anyone handling conversations where sending audio to a third-party cloud service isn't an option. The centralised administration, shared team storage, and corporate knowledge base that larger contact centres eventually want are part of the Enterprise edition, described as in development. For an individual or small team working at their own desk today, the Community edition already covers the full capture-to-write-up workflow.

Ratings

Ease of use8/10

The core recording and transcript workflow is straightforward, but getting the most out of it, connecting a SIP account, choosing a local or cloud AI model, and writing your own Prompt Studio instructions, takes some initial setup

Value for money8/10

Free, open-source GPL v2 software with no account, no per-seat licence, and no subscription for the full Community feature set, though getting the most from the AI layer means bringing your own model or API key

Innovation9/10

A live prompter that suggests what to say mid-call, not just a post-call summary, combined with free choice of local or cloud AI models, is a genuinely distinct approach among call-recording tools

Feature depth9/10

Unified call, meeting, and import capture, live prompting, two-channel recording, Prompt Studio write-ups, webhooks, and a localhost REST API cover the full workflow from first ring to CRM sync

Support8/10

Built and maintained by its author as open-source software, with active development rather than a formal ticketed support desk

Best for

Sales, support, and interview-heavy teams who spend their day across phone calls and video meetings and want one free tool that records, transcribes, and writes up every conversation, especially teams who want the option of a local AI model rather than being locked into one cloud provider.

Not ideal for

Contact centres that need centralised administration or shared team storage right now rather than on the Enterprise roadmap, and anyone whose calls happen primarily on a mobile device or an Intel-based Mac.

Pros

  • Free, open-source (GPL v2) desktop app for Windows, Apple-silicon Macs, and Linux, with no account and no per-seat subscription
  • Unifies SIP calls, Zoom, Teams, and Meet meetings, and imported recordings into one searchable, speaker-synced transcript library
  • Live prompter shows subtitles, live translation, and suggested next lines during the call itself, with four ready assistants and a practice mode
  • Automatic write-ups after every call: summaries, action items, red-flag alerts, and a custom score, all driven by 11 editable prompts in Prompt Studio
  • Works with local models (Ollama, vLLM, Llama) for fully private processing or cloud models (OpenAI, Claude, Gemini, and more) with per-call cost tracking and a spending ceiling
  • Click-to-dial, webhooks, and a localhost REST API make it straightforward to connect to a CRM
  • Available in 30 languages with dark and light themes

Cons

  • The Enterprise edition, with central administration and shared team storage, is still in development, so contact centres that need those today can bridge the gap with the webhooks and REST API to feed their own reporting layer in the meantime.
  • Getting full value from the AI features means setting up a model, a local one through Ollama or vLLM, or an API key for a cloud provider, which is a few extra minutes of setup beyond installing the app.
  • It's a desktop app for Windows, Apple-silicon Macs, and Linux, so Intel-based Macs aren't supported yet, and anyone capturing calls primarily from a mobile device will want to pair it with a mobile tool.

Verdict

AI-Softphone is aimed at a specific daily reality: a lot of professional conversation now happens across phone calls, video meetings, and the occasional recording someone imports after the fact, and most tools only handle one of those well. By treating all three as the same capture problem and adding a live prompter that helps during the call rather than only after it, it covers more of a sales, support, or interview workflow than a typical transcription app, without a subscription attached to any of it. Install it from ai-softphone.com, connect a SIP account or just start capturing your next Zoom or Teams call, and let Prompt Studio write up the first few conversations automatically. If the live subtitles and suggested next lines are still useful by your third or fourth call, it has already earned its place running in the background of every conversation after that.

Frequently asked questions

Is AI-Softphone actually free?

Yes. The Community edition is free, open-source software licensed under GPL v2, with its source published on GitHub, no account required, and no per-seat fee. An Enterprise edition with centralised administration and contact-centre connectors is described as in development, with pricing not yet announced.

What AI models can I use with it?

Either local models, including Ollama, vLLM, and Llama, for processing that never leaves your machine, or cloud services such as OpenAI, Claude, Gemini, Grok, Mistral, DeepSeek, and Groq. Cloud usage is tracked per call with a monthly spending ceiling you control.

Does it work with Zoom, Teams, and Google Meet, or just phone calls?

Both. AI-Softphone includes a built-in SIP softphone for calls on any IP PBX, and it also captures meetings running in Zoom, Microsoft Teams, Google Meet, or any other app on your computer, alongside recordings you import, all in one library.

Is my data private?

Passwords are stored in the OS keychain and data is kept locally by default. Choosing a local AI model means conversations never leave your machine. The app sends one daily anonymous usage report, which you can review yourself.

What does the live prompter do during a call?

It shows real-time subtitles, translates the other party line by line, and suggests what to say next, based on instructions you write. Four ready assistants cover subtitles, translation, objection handling, and interview help, and a practice mode lets you rehearse against an old recording.
