Hey!
I made this app to help myself write error-free emails for professional communication and also improve my writing on other sites. I hated Grammarly's intrusive UI. I wanted something simpler, yet gives me so much control over my writing. So, I built Wandpen as subtle and clean as possible. It works on your fav sites including Google Docs, Gmail, Medium, X, Outlook, LinkedIn, etc.
Link: https://wandpen.com/
There is a pricing section on the website but that's only applicable to users who are interested in using Cloud LLMs like GPT, Claude, and Gemini flash.
However, the app is completely free for anyone who wants to use Gemini Nano (built-in LLM by Chrome). Without any restrictions.
You can launch the extension by selecting a text, or right clicking on context menu, or pressing Option + W.
Please do check out the app and if you like the app, consider leaving a positive review on Chrome web store. If there is something you want to suggest, please do let me know here, I will happy to assist.
Thank you.

This is local LLM community. Can we self host this one??
WordyBug@reddit (OP)
Hi, Gemini Nano runs entirely on your browser. You don't need any server for it. Please let me know if this didn't answer your question.
smallfried@reddit
So, does it still run when my computer is completely offline?
WordyBug@reddit (OP)
Yes, you are right.
puzzleheadbutbig@reddit
I don't see that option, nowhere in your page it instructs how to run this locally? What am I missing?
WordyBug@reddit (OP)
If you select Gemini Nano on the bottom right corner model selection bar on Wandpen, this runs entirely locally.
puzzleheadbutbig@reddit
Well the thing is it doesn't even show up (the actual plugin I mean) when I select the text. So I uninstalled it right after that.
Also, it's not very logical for someone to ask to login/create account if they don't want to use the service side of the extension and it's not clear if local LLM is even supported in your page - I think you definitely need to make it clear on the actual page.
WordyBug@reddit (OP)
hey, did you check out gemini nano w/o signing up to Wandpen? I would love to hear your feedback.
puzzleheadbutbig@reddit
Hey no sorry I didn't have the chance, might check later on
WordyBug@reddit (OP)
Hey, thanks for the response.
If your plan is to only use Gemini Nano, you can ignore the login page. YOu don't need to signup/login to use Gemini Nano.
Also, if you select a text and didn't see the Wandpen tooltip, it's super weird. May I know what site did you try to run it on? Also, is the selected text in an input element/ text box? Because Wandpen tooltip only appears when you select editable text. Otherwise you may need to press Option + W to trigger Wandpen modal to do something with the selected text.
I have mentioned the support of Gemini Nano on Chrome listing page. I am looking forward to add it to my official site when Chrome stabilizes the Prompt API.
Please let me know if you have any questions.
maifee@reddit
Is your source code open sourced? That was my question.
WordyBug@reddit (OP)
No, Wandpen is not open source.
Accomplished_Mode170@reddit
For real, that’s the deal breaker for enterprises or any decent SMB
If I can’t audit your code, I can’t confidently license it and pay you
WordyBug@reddit (OP)
Oh! Thanks for the clarification. I didn't think about this. I actually started Wandpen to solve my own problem. Honestly, I don't have any experience with enterprises.
If you are interested in white label options, I would love to talk to you via DM to better understand this.
superloser48@reddit
Does it require 20GB+ of space on local computer?
"Storage: At least 22 GB on the volume that contains your Chrome profile" ?
WordyBug@reddit (OP)
This is like a prerequisite to download the model to ensure nothing breaks during the functioning of the model. However, the models doesn't take 20GB of space. It is around 2.5 GB.
Silver-Champion-4846@reddit
Can you share a link and a 'textual' guide for this thing? I'm a screen reader user so if there's any graphic content I won't be able to see it.
WordyBug@reddit (OP)
Hi, yeah I would love to help you. Are you asking for the docs of Gemini Nano from Google or you want a guide to use my app - Wandpen?
Silver-Champion-4846@reddit
Both, I guess. Gemini Nano has more promis since it's included in chrome and chrome is good with screen readers, so...
WordyBug@reddit (OP)

Have questions? contact us for assistance or feature requests.
Please let me know if you have followup questions.
Silver-Champion-4846@reddit
Can't deal with the tooltip thing as I can't reach it with the keyboard. Maybe implement an item in the context window of any edit box that opens up a dialog with the suggestions?
WordyBug@reddit (OP)
yes, you can access it from context window.
And also via this shortcut - Option + W in mac. or Alt + W in Windows.
Silver-Champion-4846@reddit
how accessible is it with a screen reader? In other words, how compatible is the ui of the extension with wcag?
QuantuisBenignus@reddit
If you would like something that is open-source, and has no GUI (speech to text and hotkeys) check out BlahST (Linux only). It has a local AI proofreader function, among other features and works in any window that has editable text field. (Disclaimer: some setup required).
For a screen reader app that can do AI summaries of selected text, also check Voluble, a Gnome shell extension.
Silver-Champion-4846@reddit
no not summaries. I just want a good tool that removes spelling issues and does things beyond that like rephrasing and changing style for unambiguity. But then again, i might just have to use hugging chat everytime I need that.
superloser48@reddit
Thanks for clarifying
abitrolly@reddit
As I understand Google releases Gemma models as free alternative to Gemini models. So what's the catch?
WordyBug@reddit (OP)
Gemini Nano runs entirely on your browser so it is 100% local and private. It doesn't consume any APIs like other cloud LLMs.
Iory1998@reddit
Thank you. How good is the Gemini Nano? Also, can it translate between Chinese and English?
And, what about the hardware requirements? Do we need to have a discreet GPU?
WordyBug@reddit (OP)
yes, it translates between chinese and english.
Iory1998@reddit
That's good. What about the other questions?
ahmetegesel@reddit
I agree. This can be replicated with an open source solution in a weekend. To be honest, it is indeed a useful tool, but not sure if it can survive. The moment it gets some traction, it will be replaced by an open source easily.
Johnny_Rell@reddit
Looks nice, but I would prefer to host my own model of choosing/API service rather than having my data flow through some random website. Plus, Gemini nano is just not enough for my usecase (creative writing)
WordyBug@reddit (OP)
would you be interested in a white labeled solution?
ohHesRightAgain@reddit
If your use case is 100% personal, you can "vibe code" a tool like this one within an hour (I would advise using Sonnet). Just stick the free Google API into it, and you are good to go. Will let you use whatever model you want. And if you don't need as many features or don't care about design (by going for hotkeys instead), you can be fully done in 5 minutes. Important keywords to mention in your prompt are "userscript" and "GM_xmlhttpRequest".
MountainGoatAOE@reddit
Open source github link?
Iory1998@reddit
He said it's not opensource.
Erdeem@reddit
It's not open source. You'll need to pay and forfeit privacy to use advanced models. 'Completely Free' is disingenuous.
WordyBug@reddit (OP)
Hi, I am readding the title here in case if you misread it:
I have explicitly mentioned it's completely free with Gemini Nano as I can't provide cloud LLMs for free bacause I have to pay for it so this will not be economically feasible.
jzn21@reddit
Cool. This is what I am looking for, except I want to bring my own keys. I am happy to pay for this app, but because of privacy, I need my own keys.
WordyBug@reddit (OP)
Hi, I am lost here, may I ask what compromises privacy in BYOK vs this?
jzn21@reddit
Thanks for your reply! Let me clarify what I meant.
We’re considering using this for drafting emails and replies, but since we’re handling sensitive personal medical data and are based in Europe, we need to comply with GDPR. That’s why privacy and control are extremely important for us.
Using your platform is interesting, but if the data flows through your infrastructure, it introduces an extra layer of risk from a privacy standpoint — especially for sensitive data. Ideally, we’d use something like OpenAI or Anthropic directly via API, or even better: a self-hosted solution through LLM Studio or OLAMA where we control both the environment and the keys.
So when I mentioned “bringing my own keys,” I meant we need to ensure that data security and compliance are fully under our control, without routing anything through third-party servers that we don’t manage.
Hope that makes more sense!
sandoz25@reddit
I'm curious how you can use anthropic or openai when they are likely to use your data. They may say they don't, but they also claimed to not use any IP that wasn't free use.
I'm generally curious and not challenging you.
Iory1998@reddit
Any AI lab is 100% using user's data... It's in their usage policy. The biggest hint is they tell us that their product is in the testing phase and researchers might see our conversation with the AI, so we should not share sensitive data. If they can see your data, then they can use it.
the_renaissance_jack@reddit
> when I mentioned “bringing my own keys,” I meant we need to ensure that data security and compliance are fully under our control, without routing anything through third-party servers that we don’t manage.
He gives OpenAI and Anthropic as examples, but the true point is total flexibility to manage the data on his own. I'm in the same boat. I use ChatGPT/Claude when necessary, but prefer my own local models where possible. Software that works as flexibly with both gets an A+ from me.
WordyBug@reddit (OP)
makes the perfect sense. If you are interested, can we talk over the DM?

Can't seem to find the source code for local hosting and development?
Strawbrawry@reddit
This looks cool but Writing tools (honestly doesn't get enough recognition) allows a lot of what people want in these comments. Can be used in Desktop and not just browser, can run your own ollama or openai api, can set up buttons for tasks you want, access via hot keys, small footprint. Again this looks cool but it feels limited
s_busso@reddit
What is the relation to local llama? This is a post to promote a commercial product that has nothing to do with llama
m91michel@reddit
Hey, congrats on the launch!
I chose a slightly different approach for rewritebar.com and instead integrated it directly into macOS.
Spirited_Salad7@reddit
totally free for 100 credit ? is this a clickbait ?
WordyBug@reddit (OP)
Hi, 100 credits is only if you use cloud LLMs like Claude or GPT.
The extension is 100% free if you choose Gemini Nano as your model in the app.
Spirited_Salad7@reddit
anyone who wants to recreate this "For Free" , type this in your google ai studio :
create a chrome extension that does this with my own gemini api : https://img.wandpen.com/wandpen%20demo%20extended.mp4
Spirited_Salad7@reddit
One prompt, two minutes... The world is going to crazy places. It even generates cute little placeholder icon when you select something. LOL!
WordyBug@reddit (OP)
lol this is so amazing.

Oh this seems not yet available for Firefox.
WordyBug@reddit (OP)
Gemini Nano not available on Firefox yet.
ahmetegesel@reddit
Hmm, would you actually need bigger models for this task? It sounds overkill
WordyBug@reddit (OP)
you mean like gpt? for me personally, I like the style and expression of gpt 4o mini. It's really clean for my use case. But that's for me personal. And I guess different users would feel different way.
ahmetegesel@reddit
Yeah but correct me if I'm wrong, it can be easily tweaked by prompt engineering.
Fhantop@reddit
Looks great! Do you know how many parameters Gemini Nano is?
WordyBug@reddit (OP)
I got this from wikipedia:
Recoil42@reddit
Heads up, your website still has pricing + claims it uses Gemini Flash 1.5.
WordyBug@reddit (OP)
Yes, pricing section is only if you want to use cloud AI models like Gemini flash, GPT 4o, Claude, etc. As I have to pay for these APIs.
However, on the app, you can select Gemini Nano as the model which is completely free without any limitations. All the features are available to free users as well.
Recoil42@reddit
Worth clarifying on your website. :)
WordyBug@reddit (OP)
I agree.
I am currently waiting for the Chrome team to make the Prompt API stable, so, I can sunset the free plan with 100 credits powered gemini flash entirely and introduce the free plan powered by Gemini Nano for all users without any limitations.
haikusbot@reddit
Looks great! Do you know
How many parameters
Gemini Nano is?
