who it's for

Who openless is for#

AI power users who compose prompts by speaking

OpenLess's AI-prompt mode converts free-form speech into a structured prompt with context and constraints, ready to paste into ChatGPT, Claude, or Cursor. Users who dictate complex, multi-part requests benefit from a cleaner output than they could produce by typing in the same time.

Skip if:

Your prompts are short and simple, or you already compose them faster by typing than by speaking. The AI-prompt mode adds the most value for complex, multi-part requests where spoken structure is hard to preserve.

Developers dictating commit messages and PR descriptions

Position your cursor in a commit message field, hold the hotkey, speak a description of your change, and OpenLess inserts a cleaned, structured version. Style packs tuned to terse commit conventions or PR description formats improve output quality beyond generic polish.

Skip if:

Your commit messages are consistently one-liners. The overhead of voice input is not worthwhile for very short, formulaic outputs.

Writers and knowledge workers drafting long-form content

Use voice input to draft emails, Slack messages, Notion documents, or specifications. Filler words are removed, paragraphs are organized, and punctuation is corrected before insertion. The light-polish mode preserves your word choices while cleaning the transcript.

Skip if:

You work in environments where speaking aloud is impractical, such as open-plan offices or public spaces.

Privacy-conscious users replacing subscription dictation tools

Users who want the Wispr Flow or Superwhisper experience without sending audio to a vendor's servers can replace their subscription with OpenLess. All processing credentials are stored in your OS keychain and audio routes directly to the API provider you configure, never through OpenLess.

Skip if:

You need a zero-configuration experience with no API key setup. OpenLess has more initial configuration overhead than a consumer subscription tool.

the problem

The problem it solves#

Converting spoken thoughts into clean, structured written text is slow and repetitive. Voice dictation apps that emit word-for-word transcripts still leave you deleting filler words, fixing punctuation, and re-organizing ideas before the text is usable. For people who work extensively in AI tools, the problem is compounded: a well-formed prompt for ChatGPT, Claude, or Cursor takes longer to type than the underlying thought, and free-form speech only gets you a rough draft that needs significant editing.

Commercial voice input tools like Wispr Flow and Superwhisper address this with AI polish layers, but they route your audio through proprietary servers, require a monthly subscription, and offer no way to bring your own ASR or LLM provider. Your vocabulary, correction history, and usage patterns are stored in their account system, not yours. When a pricing change or account issue occurs, your trained dictionary and style settings are not portable.

how openless solves it

How it solves it#

AI-prompt mode

Hold the hotkey, speak freely, and OpenLess reshapes your speech into a structured prompt complete with context, constraints, and requests. The output is ready to paste directly into ChatGPT, Claude, or Cursor, removing the typing step from AI prompt composition entirely.

Bring-your-own ASR and LLM providers

Connect to any of a dozen-plus ASR providers, including Volcengine, iFlytek, Alibaba Cloud Bailian, StepFun, OpenAI-compatible endpoints, Apple Speech, and ElevenLabs Scribe, plus a bundled local Qwen3-ASR model (0.6B and 1.7B) on macOS. LLM polish providers include DeepSeek, OpenAI, Google Gemini, and any OpenAI-compatible endpoint. Credentials are stored in your OS keychain.

Style Pack Marketplace

Create named style packs with custom system prompts, switch between them with a hotkey, and browse community packs in the in-app Marketplace. Each style pack shapes how your speech is rendered, from terse commit messages to warm customer-support replies. Uploads are moderated before they appear publicly.

Streaming insertion with clipboard fallback

Polished text is written to the cursor character by character as the AI processes it, reducing perceived latency compared to waiting for the complete result. An automatic one-shot-paste fallback activates when an application cannot accept streamed keystrokes, so no text is lost.

Vocabulary dictionary with correction learning

Add custom terms as hotwords that the ASR and polish model recognize and prefer. When you correct a word OpenLess wrote, it prompts you once to save the correction permanently. On macOS, opt-in cursor context lets the polish model read surrounding text, improving accuracy on homophones and proper nouns.

Four output modes and a translation hotkey

Choose between raw transcript, light polish, structured AI-prompt mode, and formal prose mode. A separate translation hotkey converts dictated speech directly into a configured target language without switching modes. The selection-ask QA panel adds a voice Q&A mode against highlighted text in any app.

Strengths and trade-offs#

Strengths

AGPL-3.0 licensed with no subscription feeThe codebase is AGPL-3.0 licensed as of the 2.0 beta (published 1.x releases stay under their original MIT license), and the software itself costs nothing to install and use. Wispr Flow and Superwhisper both charge monthly subscriptions with no self-hosted path. OpenLess replaces the subscription model with a bring-your-own-credentials approach: you pay only for the ASR and LLM API calls you make.
Audio and data stay on your machineOpenLess connects your device directly to the ASR and LLM providers you configure. No audio passes through OpenLess's own servers. Your vocabulary dictionary, correction history, and style packs are stored locally, not in a cloud account. For teams with compliance or privacy requirements, this is a meaningful difference from commercial alternatives.
Broad provider support prevents vendor lock-inTwelve-plus ASR providers and a comparable set of LLM polish providers are supported, including local models on macOS via the bundled Qwen3-ASR. Switching providers requires only a settings update, not a data migration. If a cloud provider changes pricing or availability, you are not blocked.
Fast-growing project with active maintenanceThe repo accumulated 3,025 GitHub stars and 274 forks in under four months after its April 2026 creation, with a commit as recent as August 14, 2026. Thirteen open issues against 274 forks is a low ratio, indicating active triage. The Discord community is live and the repo includes a beta channel for pre-release builds.

Trade-offs

-Requires setting up external ASR and LLM credentialsOpenLess does not bundle a default cloud account. First-run setup requires obtaining API keys from at least one ASR provider and one LLM provider, then entering them in Settings. Users unfamiliar with cloud AI APIs may find this step non-obvious. The bundled local Qwen3-ASR on macOS avoids cloud ASR, but the polish step still requires an LLM provider key.
-macOS builds are not Apple-notarizedThe app is ad-hoc signed rather than notarized by Apple. After installing from the DMG or Homebrew Cask, macOS users must run a one-time xattr command in Terminal to bypass the Gatekeeper warning. This extra step does not exist for commercial alternatives distributed through the Mac App Store.
-Local ASR is macOS-only; Windows offline mode is experimentalThe bundled local Qwen3-ASR model runs on macOS only. Windows local ASR via Foundry Local Whisper and sherpa-onnx is listed as experimental in the current release. Users on Windows who want fully offline transcription cannot rely on local models in the current version.

versus alternatives

openless vs alternatives#

OpenLess vs Wispr Flow

Wispr Flow is a closed-source, subscription-based voice input tool for macOS and Windows that polishes speech using its own AI backend. OpenLess targets the same workflow but replaces the subscription model with bring-your-own credentials and an AGPL-3.0 license.

Feature	OpenLess	Wispr Flow
License	AGPL-3.0	Proprietary
Price	Free (pay API costs)	Monthly subscription
Audio routing	Direct to your provider	Vendor servers
ASR providers	12+ (your choice)	Fixed (vendor-chosen)
LLM providers	12+ (your choice)	Fixed (vendor-chosen)
Local-first data	Yes	No

OpenLess is the better choice when data privacy matters, when you want to control which AI providers process your audio, or when you want to avoid a monthly software fee. Wispr Flow is the easier starting point if you want a zero-configuration experience and are comfortable with a subscription and vendor-managed AI.

OpenLess vs Superwhisper

Superwhisper is a macOS-only voice input tool with AI polish, distributed as a closed-source subscription product. OpenLess is cross-platform (macOS and Windows, with Android APKs available) and AGPL-3.0 licensed.

Feature	OpenLess	Superwhisper
License	AGPL-3.0	Proprietary
Platform	macOS, Windows, Android	macOS only
Price	Free (pay API costs)	Monthly subscription
Local ASR	Yes (macOS, Qwen3-ASR)	Yes
AI-prompt mode	Yes	No (polish only)
Style packs	Yes, with community marketplace	Limited presets

OpenLess adds an AI-prompt mode that Superwhisper does not have, making it a better fit for users who primarily use voice input to compose prompts for AI tools. Superwhisper requires less initial configuration and is more polished for macOS users who do not need bring-your-own credentials.

OpenLess vs Willow Voice and FluidVox

Willow Voice and FluidVox are also paid, proprietary voice input tools with subscription pricing and no option to bring your own ASR or LLM provider. OpenLess distinguishes itself from both by offering AGPL-3.0 licensing, local-first data storage, and a provider-agnostic architecture that supports a dozen-plus ASR and LLM backends. For users who need to switch providers or avoid a specific vendor for compliance reasons, OpenLess is the only option in this category that supports that flexibility.

frequently asked

FAQ#

Is OpenLess free to use?

Yes. OpenLess is AGPL-3.0 licensed and free to download and install. You pay only for the ASR and LLM provider API calls you make; the application itself has no subscription fee. For light personal use, free tiers on providers like OpenAI or Apple Speech (macOS) can keep API costs minimal.

What platforms does OpenLess support?

OpenLess runs on macOS 12 and later (Apple Silicon and Intel) and Windows 10 and later. Android APK builds are available in GitHub Releases. There is no native Linux desktop app in the current release. The Homebrew Cask install path is macOS only; Windows users download an EXE installer from the Releases page.

Does OpenLess send my audio to its own servers?

No. OpenLess connects your device directly to the ASR and LLM providers you configure in Settings. Your audio and text pass only to those providers. OpenLess operates no audio-processing backend of its own. Your vocabulary dictionary, correction history, and style packs are stored locally on your machine.

How is OpenLess different from standard speech-to-text dictation?

Standard dictation outputs a word-for-word transcript that still requires editing to remove filler words and fix structure. OpenLess adds an AI polish step that cleans the transcript and, in AI-prompt mode, reshapes free-form speech into a structured prompt ready to paste into ChatGPT, Claude, or Cursor. The polish step runs through the LLM provider you configure, not a fixed vendor backend.

Can I use OpenLess without a cloud ASR provider?

On macOS, yes. OpenLess bundles a local Qwen3-ASR model (0.6B and 1.7B variants) that handles transcription without any cloud ASR API. The polish step still requires a cloud LLM provider key in the current release. On Windows, local ASR via Foundry Local Whisper and sherpa-onnx is listed as experimental and may not be production-ready.
